Step 1: Peel the bananas and slice them into 1/2-inch thick rounds. Ensure you have an even number of slices.
Step 2: Lay half of the banana slices on a baking sheet lined with parchment paper. Place a small dollop (about 1/2 teaspoon) of peanut butter onto each slice.
Step 3: Top each peanut butter-covered slice with another banana slice to create a sandwich. Place the tray in the freezer for at least 1 hour until firm.
Step 4: In a small microwave-safe bowl, combine the dark chocolate chips and coconut oil. Microwave in 30-second increments, stirring until completely smooth.
Step 5: Using a fork, dip each frozen banana sandwich into the melted chocolate to coat thoroughly. Place back on the parchment paper and immediately sprinkle with crushed peanuts and sea salt.
Step 6: Return the Frozen Banana Snickers Bites to the freezer for another 30 minutes to set the chocolate. Serve frozen.
