Place 15 banana slices on a baking sheet lined with parchment paper. Spread about a teaspoon of peanut butter on top of each banana slice.
Top with another banana slice, and slightly press them together to make banana peanut butter “sandwiches.”
Transfer the bananas with peanut butter to the freezer for about 1 hour to harden.
Melt together the chocolate chips and coconut oil in either a microwave or over a double boiler until the chocolate is completely smooth.
Remove the bananas with peanut butter from the freezer and carefully dip them into the melted chocolate. Place the chocolate-dipped bananas back onto the baking sheet.
Freeze the banana and peanut butter bites for about 30 minutes, or until the chocolate has hardened and you’re ready to eat!
