Melt the chocolate chips in a saucepan. Use a brush to line cupcake liners with a thin layer of chocolate. Put in the freezer.
Put all the remaining ingredients in a VitaMix (high speed blender) and blend – you can leave some chunks, it does not need to be totally smooth, but you can if you want.
Take the cupcake pan out of the freezer and add the peanut butter filling. Push it down in each cupcake liner, and cover with a thin layer of the remaining chocolate. Put in the freezer or refrigerator. The chocolate with harden quickly so fear not, the wait won’t be more than a few minutes!
