Spread peanut butter on half of the banana pieces and top it with the other half of banana pieces. Do not worry if it looks messy it will turn out great.
In a pan, warm up coconut oil and chocolate chips on low. Stirring consistently until they melt together. Careful not to burn it!
On a silicone baking mat, drizzle the melted chocolate over the banana sandwiches.
Freeze for at least 20 minutes. The inside will still be soft but the coating should be hard around 20 minutes -My preference. Freeze longer for frozen bites all the way through.
