Cover a baking sheet with parchment paper. Slice the bananas about ¼" thick. Arrange half the slices on the baking sheet. Spread peanut butter onto each slice and then top with another banana slice. Place in freezer for 30 minutes.
Place chocolate and coconut oil in heat proof bowl and heat in 30 second intervals until chocolate is melted.
Using a fork, dip the frozen bananas in the chocolate until it's coated. Place back on baking sheet with parchment paper and repeat until all bananas are coated. Place in freezer for 1 ½ hours or until they are set. You can eat immediately or let out of freezer for a couple of minutes before eating.
Notes
Use quality dark chocolate. If you don’t love dark chocolate, semi-sweet or milk chocolate works as well.
Use refined coconut as it doesn't have a coconut flavor but allows the chocolate to set.
The banana bites will last in the fridge in an airtight container for a week or in the freezer for 6 months.
