Peel and slice bananas into rounds about 1/4 inch thick.
Line a baking sheet with parchment paper.
Spread about 1/2 teaspoon peanut butter onto one banana slice and top with another slice to create a sandwich.
Repeat until all banana slices are used, forming about 30 bites.
Place the bites on the prepared sheet and freeze for 1 hour.
In a microwave-safe bowl, melt chocolate chips with coconut oil in 30-second intervals, stirring until smooth.
Remove frozen bites and dip each one halfway into the melted chocolate.
Place coated bites back on the parchment-lined tray.
Freeze again for 15 minutes until chocolate is set.
Enjoy your Chocolate Peanut Butter Banana Bites immediately or store for later.
