Making Frozen Chocolate Peanut Butter Banana Bites is a straightforward process. Follow these steps:

1. Prepare the Bananas: Peel the bananas and cut them into bite-sized slices, roughly ½ inch thick.
2. Spread Peanut Butter: On half of the banana slices, spread a generous amount of peanut butter.
3. Top with Banana: Place another banana slice on top of the peanut butter-spread slice, creating a mini sandwich.
4. Line a Baking Sheet: Use parchment paper to line a baking sheet to prevent sticking.
5. Arrange the Bites: Place the banana sandwiches on the lined baking sheet in a single layer.
6. Melt the Chocolate: In a microwave-safe bowl, combine the dark chocolate chips and coconut oil. Microwave in 30-second intervals, stirring in between, until fully melted and smooth.
7. Dip the Bites: Using a fork, dip each banana sandwich into the melted chocolate, allowing excess chocolate to drip off.
8. Sprinkle Toppings: Before the chocolate hardens, sprinkle with sea salt, chopped nuts, or shredded coconut if desired.
9. Freeze: Place the baking sheet in the freezer for at least 1 hour or until the chocolate is completely set.
10. Store: Once frozen, transfer the banana bites to an airtight container. Keep them stored in the freezer for the best quality.

This straightforward process guides you in creating marvelous treats that meld well together.
