How to Make Chocolate Peanut Butter Cup

Fill your cups with a small spoonful of melted chocolate, then use the paintbrush to paint the chocolate up the sides of the cup to the top. Try to create an even layer, and inspect the cups as you finish them to make sure there are no weak, streaky areas. Once all of the cups have been lined with chocolate, set aside the remaining chocolate for later and let the cups set at room temperature or in the refrigerator until they have hardened.
