Slice the ripe bananas into 1/4-inch thick rounds and place half on a parchment-lined baking sheet.

Soften peanut butter in a microwave-safe bowl for 30 to 45 seconds, then spoon 1/2 teaspoon onto each banana slice.

Press remaining banana slices on top of the peanut butter-covered slices to create sandwiches.

Freeze the assembled bites for about 1 hour until solid.

Melt chocolate chips and coconut oil in a microwave-safe bowl until fully melted and smooth.

Dip each frozen banana bite into the melted chocolate and place back on the baking sheet.

Return to the freezer for at least 1 additional hour to allow chocolate to set.

Store in a freezer-safe bag or container for up to 1 month.
