I made S'mores themed cupcakes for my son, Charles, to take to school for his 8th Birthday.
To make them, I used chocolate cupcakes, filled them with a marshmallow frosting, and finished them off with a graham cracker buttercream frosting. Oh...and I topped them all with a hershey's chocolate piece.
I used these recipes:
buttercream frosting (mix in 1/4 cup of graham cracker crumbs)
