Creating the ultimate Strawberry Shortcake in a Jar is straightforward if you follow these steps:

1. Prepare Strawberries: In a bowl, combine sliced strawberries with granulated sugar and vanilla extract. Let them sit for about 15 minutes to release their juices.
2. Whip Cream: In another bowl, beat the heavy whipping cream and powdered sugar using a hand mixer until soft peaks form.
3. Layer Ingredients: Take your jars and create layers starting with a layer of pound cake cubes at the bottom.
4. Add Strawberries: Spoon a generous amount of strawberry mixture over the cake layer.
5. Add Whipped Cream: Dollop whipped cream on top of the strawberries.
6. Repeat Layers: Continue layering with more pound cake, followed by strawberries, and then whipped cream until the jar is filled. Aim for at least three layers.
7. Chill: Cover the jars with lids or plastic wrap and refrigerate for at least one hour to set.
8. Garnish: Before serving, add a fresh mint leaf on top of each jar for an extra touch of color and flavor.

These steps will guide you through the process of assembling your delicious Strawberry Shortcake in a Jar.
