Celebrating National Chocolate Cupcake Day 5 Guys 1 Plate style. We didn't have a cupcake pan and we don't know how to properly decorate. So the end result, from this point on, will forever be known as a "5 Guys Cake". It's a cross between a cupcake and absolute chaos. In the end though it all turned out great, we had our cupcake and ate it too. Now show us some pictures of you celebrating National Chocolate Cupcake Day.
