Peanut Butter Mousse: Easy No-Bake Dessert with 5 Ingredients

There’s something inherently nostalgic about the flavor of peanut butter. Whether it brings back memories of childhood lunches or late-night snacks straight from the jar, it’s one of those ingredients that instantly evokes comfort. Now, imagine that warm familiarity blended with silky cream cheese, sweetened just enough, and folded into fluffy clouds of whipped cream. What you get is a decadent yet light dessert: peanut butter mousse.

This no-bake peanut butter mousse is my personal love letter to all the creamy desserts out there. It’s incredibly smooth, has the perfect peanut butter-to-cream ratio, and feels luxurious without being fussy. The best part? You don’t need a stovetop, oven, or even fancy kitchen tools. All it takes is a few bowls, a hand mixer, and a little patience (mostly to resist eating the entire batch before it chills).

I first created this recipe during a time when I was experimenting with quick desserts that didn’t require baking. I had some cream cheese that needed to be used, a jar of peanut butter I couldn’t resist dipping into, and a craving for something sweet but not overly rich. One bowl led to another, a few whisks later, and there it was—fluffy, sweet, creamy peanut butter mousse. Since then, it’s become a staple in my kitchen.

This mousse has earned a permanent spot in my dessert rotation not just because of how easy it is to make, but because it feels special enough for celebrations yet simple enough for a regular Tuesday night. Serve it in little jars, top it with crushed peanuts, chocolate shavings, or even a drizzle of honey—it’s the kind of dessert that’s endlessly customizable and always crowd-pleasing.

Whether you’re hosting a dinner party, prepping make-ahead treats for the week, or just indulging in a quiet moment to yourself, this peanut butter mousse is your new best friend in the kitchen.

Why You’ll Love This Recipe

There are plenty of reasons this peanut butter mousse is going to win you over. From its minimal ingredient list to its cloud-like texture, this dessert checks all the right boxes. If you’ve never made mousse before, don’t worry—this version is completely beginner-friendly and requires no complicated techniques or equipment.

1. It’s Effortless Yet Impressive

One of the standout features of this recipe is how effortlessly it comes together. You’ll only need five main ingredients, most of which you probably already have on hand. The process involves mixing, whipping, and folding—no baking, cooking, or chilling required unless you prefer a firmer texture. Despite being so easy to make, the result is elegant and polished. It’s the kind of dessert that looks and tastes like you spent hours making it, even though you barely spent 20 minutes.

2. Creamy and Dreamy Texture

Texture is everything in mousse, and this one nails it. The cream cheese gives it a slight tang and richness, while the whipped cream lightens everything up and adds that signature airiness. The peanut butter brings depth and a lovely nutty creaminess. Together, they form a dessert that is both velvety and pillowy at the same time. Every bite melts on your tongue and leaves you wanting just one more spoonful.

3. Crowd-Pleaser for All Ages

Kids love it. Adults devour it. And even people who claim they don’t like peanut butter end up asking for seconds. This dessert hits that sweet spot (literally and figuratively) where it appeals to a wide range of palates. It’s indulgent without being too heavy, and customizable for different flavor preferences—add chocolate chips, swirl in some jam, or top it with whipped cream and nuts. The possibilities are endless.

4. Make-Ahead and Meal-Prep Friendly

If you’re someone who loves preparing ahead for guests or simply enjoys having a little sweet treat ready to go in the fridge, this mousse is ideal. It holds up beautifully in the fridge for days, and its texture actually improves after a few hours of chilling. You can serve it in jars, ramekins, or glasses, making it perfect for individual servings and easy storage.

Health Benefits

At first glance, a dessert like this may not seem like it would offer any health benefits, but when you look a little closer, there are actually some surprising nutritional upsides—especially when compared to traditional desserts that are heavy on refined sugars and saturated fats.

1. Peanut Butter Offers Protein and Healthy Fats

Peanut butter isn’t just delicious; it’s also a good source of plant-based protein and healthy monounsaturated fats. These fats are known to support heart health when consumed in moderation. In addition, peanut butter contains essential vitamins and minerals like magnesium, vitamin E, niacin, and phosphorus. The protein and fat combo helps with satiety, meaning this dessert can help you feel full and satisfied with a smaller portion.

2. Cream Cheese Adds Calcium and Fat-Soluble Vitamins

Full-fat cream cheese, while rich, does contribute important nutrients like calcium, vitamin A, and B vitamins. Calcium is crucial for bone health, and vitamin A supports immune function and vision. The fat-soluble nature of these vitamins means they’re more easily absorbed in a dish like this, where fat is present in natural and unprocessed forms.

3. Heavy Cream in Moderation Can Support Nutrient Absorption

Although heavy whipping cream is calorie-dense, it also enhances the overall creaminess and adds structure to the mousse. In moderation, it helps with the absorption of fat-soluble vitamins from the other ingredients. Plus, it’s a better alternative to many ultra-processed whipped toppings, which often contain hydrogenated oils and artificial additives.

4. Low-Sugar or Sugar-Free Options Are Easily Available

This recipe is incredibly flexible when it comes to sweetness. You can easily use a low-carb powdered sweetener like erythritol, monk fruit blend, or stevia-based sugar substitutes without sacrificing texture or flavor. That means if you’re trying to manage your blood sugar or reduce refined sugar intake, this mousse can be adapted to fit into a balanced eating plan.

5. No Artificial Ingredients or Preservatives

Since you’re making it at home, you know exactly what’s going into it. Unlike store-bought mousses or packaged puddings, which are often full of stabilizers, artificial flavors, and preservatives, this recipe uses only whole ingredients. That makes it not just a tastier option, but also a cleaner one.

Preparation Time, Servings, and Nutritional Information

Ingredients List

Now that you’re ready to get started, gather the following ingredients. The beauty of this list is its simplicity—just a handful of pantry and fridge staples that come together to make something magical.

Main Ingredients

• 1 cup peanut butter (smooth, not natural or crunchy): The smooth texture is key to achieving that creamy consistency. Natural peanut butters with separated oils can make the mousse grainy or too loose. Choose a brand that’s already emulsified.

• 1 cup cream cheese (softened, full-fat preferred): For best results, use full-fat cream cheese and let it soften at room temperature before mixing. This ensures it blends smoothly without lumps.

• 1 cup powdered sugar (or low-carb alternative): This adds the necessary sweetness and also helps stabilize the mousse. Powdered erythritol or other sugar-free substitutes work well here.

• 1 cup heavy whipping cream: Whipping the cream separately and folding it in adds air and creates that mousse-like texture. Make sure it’s cold for the best whip.

• Optional: 1 teaspoon vanilla extract: A touch of vanilla deepens the overall flavor and balances the richness. It’s optional, but highly recommended.

Step-By-Step Cooking Instructions

Here’s where the magic happens. Follow these steps, and you’ll have a luscious peanut butter mousse ready in no time. No oven. No stovetop. No stress.

Step 1: Soften the Cream Cheese
Take the cream cheese out of the fridge at least 30 minutes before starting. This makes it easier to beat into a smooth consistency and ensures it blends well with the other ingredients. If you’re in a hurry, you can soften it slightly in the microwave for 10-15 seconds.

Step 2: Combine Peanut Butter and Cream Cheese
In a large mixing bowl, use an electric mixer on medium speed to beat the peanut butter and cream cheese together. Mix until the texture is smooth, creamy, and fully combined. This step ensures there are no lumps and that your base is rich and uniform in texture.

Step 3: Add Powdered Sugar and Vanilla Extract
Once the mixture is smooth, add in the powdered sugar and vanilla extract. Continue mixing until the sugar is fully incorporated. Taste at this point to check sweetness. If you like it sweeter, you can add a bit more powdered sugar or sweetener to your liking.

Step 4: Whip the Cream
In a separate chilled bowl, pour in the heavy whipping cream. Using clean beaters or a whisk attachment, whip the cream on high speed until stiff peaks form. You’ll know it’s ready when the cream holds its shape and doesn’t droop when you lift the beaters.

Step 5: Fold Whipped Cream into Peanut Butter Mixture
Now it’s time to bring everything together. Gently fold the whipped cream into the peanut butter mixture using a silicone spatula. Do this in 2 to 3 batches to avoid deflating the whipped cream. Use broad, sweeping motions to incorporate the cream without losing the airy texture.

Step 6: Taste and Adjust
Once everything is combined, give it a taste. Adjust the sweetness or saltiness if needed. If it’s too rich for your preference, you can lighten it further by folding in a bit more whipped cream.

Step 7: Chill or Serve Immediately
You can serve the mousse right away for a soft, creamy texture, or refrigerate it for at least 1 hour to let it firm up slightly. Chilling also deepens the flavor, making it even more indulgent.

Step 8: Portion and Garnish
Spoon or pipe the mousse into small jars, bowls, or ramekins. Garnish with a sprinkle of crushed peanuts, shaved chocolate, or even a dollop of whipped cream. You could also add a few chocolate chips or a drizzle of melted dark chocolate on top.

Step 9: Serve and Enjoy
Bring it to the table and watch it disappear. Whether served as-is or with toppings, this peanut butter mousse always makes a lasting impression.

Step 10: Clean Up and Save Leftovers
This dessert is just as easy to clean up as it is to make. Seal leftovers in an airtight container and refrigerate. It keeps well and actually tastes better the next day.

How to Serve

Presentation plays a big part in elevating any dessert, and this peanut butter mousse is no exception. Because it’s so smooth and airy, it works well in a variety of serving vessels and formats. Whether you’re planning an elegant dinner party or just want to enjoy a cozy dessert for one, the way you serve your mousse can truly enhance the experience.

1. Individual Dessert Cups

One of the most common and convenient ways to serve mousse is in small glasses or jars. Think ramekins, mason jars, mini parfait cups, or even wine glasses. Serving it this way makes it easy to control portion sizes, and it looks beautiful layered with toppings.

2. Family-Style Bowl for Sharing

If you’re hosting a casual gathering or want to keep things low-maintenance, scoop the entire mousse into a large serving bowl and let everyone dig in. Offer a selection of toppings on the side so guests can build their own perfect dessert bowl.

3. Layered Parfaits

For an eye-catching presentation, layer the mousse with crushed graham crackers, crumbled cookies, or chocolate shavings. Add a drizzle of caramel or melted dark chocolate between the layers. This not only adds texture but also brings depth to each bite.

4. Frozen Dessert Alternative

If you’re in the mood for something cool and refreshing, freeze the mousse in popsicle molds or small silicone muffin cups. Once frozen, you’ll have a peanut butter ice cream-like treat that’s perfect for summer afternoons.

5. Add a Garnish

Don’t underestimate the power of a good garnish. Here are a few topping ideas that pair beautifully with the rich, nutty flavor of the mousse:

• Crushed roasted peanuts or almonds for crunch
• Mini chocolate chips or chocolate curls
• A drizzle of melted peanut butter or chocolate
• Whipped cream and a dusting of cocoa powder
• Fresh banana slices or strawberries for a fruity contrast

No matter how you serve it, this mousse will always feel like a treat—and the presentation possibilities are endless.

Pairing Suggestions

What you serve alongside your peanut butter mousse can make all the difference. Whether you’re looking for complementary textures, contrasting flavors, or complete meal ideas, there are plenty of ways to turn this dessert into a standout course.

1. Serve with Fresh Fruit

Fruits bring a juicy, acidic brightness that cuts through the richness of the mousse. Berries—such as raspberries, strawberries, and blueberries—pair particularly well with the creamy peanut flavor. You can either serve the fruit on the side or layer it into the dessert.

Bananas are also a natural pairing with peanut butter. Try placing a few fresh banana slices on top of the mousse or layering them between spoonfuls for added sweetness and texture.

2. Offer a Crunchy Side

Since the mousse itself is so soft and fluffy, pairing it with something crispy or crunchy creates a more dynamic bite. Try offering:

• Butter biscuits or shortbread cookies for dipping
• Pretzel sticks for a salty crunch
• Graham crackers or chocolate wafer cookies as a base or side

These crunchy elements balance the smoothness of the mousse while making it even more fun to eat.

3. Hot Beverages to Balance the Chill

If you’re serving the mousse chilled or frozen, warm beverages create a cozy contrast. Some great options include:

• A strong brewed coffee or espresso
• A chai tea latte with warming spices
• A decaffeinated herbal tea like mint or chamomile for a mellow ending to your meal

The bitterness of coffee, especially, pairs wonderfully with the sweetness and nuttiness of the mousse.

4. Serve After a Light Meal

Because this mousse is quite rich, it’s best served after a light meal. Think grilled chicken salads, roasted vegetables, or lean protein dishes. Avoid overly heavy main courses, which could compete with the richness of the dessert.

5. Make it a Dessert Flight

Why not turn dessert into an event? Serve the mousse alongside small portions of other easy no-bake treats, like mini cheesecakes, fruit sorbets, or chocolate truffles. This gives guests a chance to explore different textures and flavors—and it’s always fun to have options.

Storage, Freezing & Reheating Instructions

One of the many perks of this peanut butter mousse is that it stores beautifully. Whether you want to prep it ahead for a party or simply enjoy leftovers throughout the week, knowing how to properly store it will help maintain its texture and flavor.

1. Refrigeration for Short-Term Storage

For best results, store the mousse in an airtight container in the refrigerator. It will keep well for up to 4 days. In fact, the flavor tends to deepen slightly after a day of chilling, and the texture firms up just enough to make it even more luxurious.

If you’re storing individual servings, cover each jar or ramekin tightly with plastic wrap or a lid to prevent moisture or fridge odors from affecting the mousse.

2. Freezing for Long-Term Storage

Yes, you can absolutely freeze this mousse. While the texture changes slightly—becoming more like peanut butter ice cream—it’s still delicious and refreshing when served frozen.

Here’s how to do it:

• Spoon the mousse into freezer-safe containers.
• Leave a little space at the top to allow for expansion.
• Seal tightly with lids or plastic wrap.
• Freeze for up to 2 months.

When you’re ready to enjoy, thaw the mousse in the fridge for 2 to 3 hours if you want a softer texture. Alternatively, serve straight from the freezer as a frosty dessert.

3. Reheating Is Not Recommended

Since this is a chilled dessert, reheating isn’t necessary—and actually not recommended. High heat would break down the whipped cream and cream cheese, resulting in a separated, runny mixture. Instead, let it sit at room temperature for 5 to 10 minutes before serving if it’s too firm.

4. Texture Tips After Storage

If the mousse looks like it has deflated slightly after refrigeration or freezing, give it a gentle stir to restore some of the fluffiness. For an even more luxurious texture, you can fold in a spoonful of freshly whipped cream before serving.

Common Mistakes to Avoid

Even though this recipe is wonderfully simple, a few common mistakes can interfere with the final result. Here are some pitfalls to watch out for so your mousse turns out perfectly every time.

1. Using Natural Peanut Butter

While natural peanut butter is great for sandwiches, it’s not ideal for this recipe. The oil separation in natural varieties can make your mousse greasy or cause it to separate. Stick with smooth, no-stir peanut butter for the best results.

2. Not Softening the Cream Cheese

Cold cream cheese doesn’t blend well and can create lumps in your mousse. Make sure to let it sit at room temperature for 30 minutes before using. If you’re pressed for time, microwave it for 10 seconds, but don’t overdo it or it could become too runny.

3. Over-Whipping the Cream

It’s important to whip the cream until stiff peaks form, but over-whipping can turn it grainy or even start to form butter. Keep a close eye and stop whipping as soon as the cream holds its shape when the beaters are lifted.

4. Deflating the Whipped Cream While Folding

When folding the whipped cream into the peanut butter base, use a gentle hand. Stirring too vigorously will knock out the air you just whipped in, making your mousse less airy and fluffy. Fold with slow, deliberate motions using a rubber spatula.

5. Adding Too Much Sweetener

It can be tempting to add extra sugar, especially if you prefer a sweeter dessert. But too much powdered sugar can overpower the peanut flavor and make the mousse too dense. Start with the suggested amount and taste as you go.

Pro Tips

To take your mousse from good to absolutely unforgettable, here are some tried-and-true tips that will elevate your final dish and make the process even smoother.

1. Chill Your Mixing Bowl and Whisk

When whipping heavy cream, using a chilled metal bowl and cold beaters helps achieve stiff peaks faster. Simply pop your bowl and whisk into the freezer for 10 minutes before starting. This is especially helpful in warmer kitchens.

2. Use High-Quality Ingredients

Since this recipe has so few ingredients, quality really does make a difference. Use a good brand of peanut butter, fresh cream cheese, and pure vanilla extract (not imitation). Each component contributes to the final flavor, so using the best you can find or afford will elevate the mousse.

3. Mix the Base Thoroughly Before Folding

Before you add the whipped cream, make sure your peanut butter, cream cheese, and sugar mixture is completely smooth and well-blended. Any lumps at this stage will be harder to fix later and could affect the texture of your mousse.

4. Customize the Flavor

This recipe is a fantastic base for a variety of flavor combinations. You can add a tablespoon of cocoa powder for a chocolate peanut butter twist, swirl in some raspberry jam for a PB&J vibe, or sprinkle cinnamon for a warm, spiced note.

5. Let It Rest for Deeper Flavor

If you have the time, refrigerate the mousse for a few hours before serving. This gives the flavors time to meld and intensify, and the texture becomes more luxurious with time.

Frequently Asked Questions (FAQs)

No matter how simple a recipe may seem, there are always a few questions that come up—especially when you’re working with whipped cream and cream cheese. Below, you’ll find answers to the most common questions I’ve received about this no-bake peanut butter mousse. These should help you troubleshoot, adapt, and perfect the dessert every time you make it.

1. Can I use crunchy peanut butter instead of smooth?

While you technically can use crunchy peanut butter, it will significantly change the texture of the mousse. The smooth, airy consistency that makes this dessert so special comes from using smooth peanut butter. Crunchy versions tend to disrupt the mousse’s fluffiness, making it feel more like a thick dip than a dessert. If you really want a bit of crunch, consider folding in chopped peanuts at the end instead.

2. Can I make this mousse ahead of time?

Yes, absolutely. In fact, this mousse is one of the best make-ahead desserts you’ll find. Once made, it can be stored in the fridge for up to four days without losing its texture. If you’re preparing it for a special event, you can make it the night before, portion it into serving cups, and keep it covered until you’re ready to serve.

3. What’s the best sugar substitute for a low-carb version?

If you’re trying to keep the carb count low or avoid refined sugars, powdered erythritol and powdered monk fruit sweetener both work really well. You’ll want to avoid granulated sugar substitutes, as they can make the mousse grainy. Powdered alternatives dissolve much more smoothly into the cream cheese and peanut butter mixture.

4. Can I freeze peanut butter mousse?

Yes, this mousse freezes surprisingly well. It becomes slightly firmer and takes on a texture similar to ice cream, which is especially nice during hot months. To freeze, spoon the mousse into airtight containers or silicone molds. It will keep for up to two months. Just let it thaw in the fridge for a few hours before serving if you prefer a softer consistency.

5. Can I double or halve the recipe?

This recipe is incredibly forgiving and can easily be doubled or halved. If you’re hosting a big group, double the ingredients and prepare in a large bowl, then portion into serving cups. If you’re making it just for yourself or a couple of people, halve everything and follow the exact same steps.

6. What if I don’t have a hand mixer?

If you don’t have an electric hand mixer, you can still make this mousse with a whisk and some elbow grease. The most challenging part will be whipping the cream, but it’s doable if you use a chilled metal bowl and whisk vigorously. It might take a bit longer, but the results will be just as tasty.

7. My mousse looks runny. What went wrong?

A few things could cause a runny mousse. First, make sure the whipped cream was beaten until stiff peaks formed. If it was under-whipped, it won’t hold structure well. Second, don’t use natural peanut butter, as its oil separation can cause the base to become too loose. Finally, folding the whipped cream too aggressively can deflate it, resulting in a less airy texture.

8. Can I turn this mousse into a pie filling?

Yes, this mousse makes an excellent no-bake pie filling. Simply pour the prepared mousse into a pre-made or homemade graham cracker crust and chill for several hours until firm. You can top the pie with whipped cream, shaved chocolate, or a drizzle of melted peanut butter for a show-stopping dessert.

9. Is there a dairy-free version of this recipe?

It is possible to make a dairy-free version, although the texture may vary. Use dairy-free cream cheese (such as almond- or cashew-based) and substitute the heavy cream with chilled full-fat coconut cream. You’ll need to whip the coconut cream just as you would dairy cream. Keep in mind that the flavor may change slightly, but it’s a great option for those avoiding dairy.

10. Can I add chocolate to the mousse?

Definitely. You can stir in a tablespoon or two of cocoa powder into the peanut butter mixture for a chocolate-peanut butter mousse. Alternatively, fold in mini chocolate chips or layer the mousse with melted chocolate for a parfait-style dessert. The combination of peanut butter and chocolate is always a crowd favorite.
