This recipe is great because it includes candy pieces in the cupcakes as well as on the icing. You will need two 10 packs of fun-sized candy bars to make these cupcakes, 12 for the cupcakes, and 8 for the icing.
Chop all of the Baby Ruth Bars. Set aside half for the cupcake batter and half for the icing.
Combine all of the ingredients for the cupcakes, except the candy pieces, into a large bowl and beat until pale. Slowly mix in the candy chunks by hand.
Spoon batter into the baking cups and bake for 20 minutes, or until done. Check with a toothpick.
While the cupcakes cool, you can assemble your icing. Beat the powdered sugar and butter until icing is formed. Spread on the cooled cupcakes, and top the cupcakes off by sprinkling the remaining candy pieces on top.
