In a small bowl combine the ingredients for the chocolate layer and stir until everything is well combined. In a separate small bowl, combine ingredients for the peanut butter layer and stir until everything is well combined. Both mixtures should be free of clumps and creamy.
Line mini muffin tin with 14 mini muffin liners (I used silicone), and spray with cooking spray. Pour 1 tsp of the chocolate mixture into each liner. Follow with 1 tsp of the peanut butter mixture on top of the chocolate layer, and finish off by pouring 1 tsp of the chocolate mixture on top of the peanut butter layer.
Place muffin tin in the freezer and freeze for 1-2 hours, or until they are firm enough to remove from the muffin liners. Enjoy! (Note: These must be kept and stored in the freezer! They can be enjoyed by popping them out of the freezer about 10 minutes before enjoying!)
