Slice the bananas into about 12 slices per banana. You can slice them crosswise or lengthwise depending on your preferred shape.
Spread about 1 teaspoon of peanut butter onto one banana slice and top it with another banana slice to create a sandwich.
Place the peanut butter banana sandwiches onto a baking sheet or tray lined with parchment paper.
Freeze for 15 minutes so the banana bites firm up before dipping.
While the bananas chill, melt the chocolate chips. Microwave in 30-second intervals, stirring each time until smooth. You can also melt the chocolate using a double boiler on the stovetop.
Remove the banana bites from the freezer. Using a fork, dip each one into the melted chocolate until fully coated.
Return the coated Chocolate Peanut Butter Banana Bites to the tray and freeze for another 15 minutes or until the chocolate hardens.
Transfer the frozen bites to an airtight container and store in the freezer for up to 2 weeks.
