Line a baking sheet with parchment paper or a silicone baking mat. This will prevent the banana from sticking to the sheet and make for easy removal later.

Cut up bananas into 1 inch slices and add to prepared baking sheet. Make sure all banana slices are touching.

Cover with another piece of parchment paper. Using the bottom of a glass, press down on banana pieces so they become one layer.

Add melted peanut butter over the banana layer and add to freezer for 30 minutes until hardened.

In a microwave-safe bowl or using a double boiler, melt the dark chocolate and coconut oil until it becomes smooth and glossy. Stir occasionally to ensure even melting.

Once the banana and peanut butter layer have hardened, add the melted chocolate over top. Sprinkle with course sea salt and add back to freezer to harden again.

Once solidified, break up the chocolate peanut butter banana bark into pieces. Enjoy!
