I found this recipe through Crazy Daisy's Tuesday Taste. It looked like something my kids and husband would love. S'mores are like the greatest ever and put that on top of a cupcake. You have something irresistible. I varied the recipe a little. I chose to frost with marshmallow fluff, instead of mixing half frosting, half marshmallow.
1 chocolate cake mix
Crush your graham crackers and mix with melted butter to make crust. I used a 1/2 of a stick and 1 package of graham crackers for the crust. set aside
Prepare cake mix to box directions.
Line pan with cupcake liners. Fill the bottom with a thin layer of the graham cracker mixture.
Then fill the cups with the chocolate cake mix. Top the cake mix with a sprinkling of chocolate chips. Bake according to box directions.
Allow the cupcakes to cool completely and frost with marshmallow fluff. Drizzle some chocolate sauce on top and finish with a toasted marshmallow.
