Peel the bananas and slice them into rounds approximately ¼-inch thick.

Line a baking sheet, tray, or large plate with parchment paper.

Spread about ½ teaspoon of peanut butter onto one banana slice.

Top with another banana slice to create a mini sandwich.

Repeat until all banana slices have been used.

Arrange the banana sandwiches on the prepared tray.

Freeze for at least 1 hour or until firm.

Add the dark chocolate chips and coconut oil to a microwave-safe bowl.

Microwave for 1 minute and stir.

Continue microwaving in 30-second intervals until fully melted and smooth.

Remove half of the frozen banana bites from the freezer.

Dip each bite halfway into the melted chocolate.

Return them to the parchment-lined tray.

Repeat with the remaining bites.

Freeze for another 15 minutes until the chocolate hardens.

Enjoy immediately or store in a freezer-safe container.
