1 box of Devils Food Cake, plus the ingredients to make it
Bake cupcakes according to package directions.
Once the cupcakes have fully cooled, place one on a microwave safe plate and top them with a marshmallow. Microwave for 5-10 seconds.
In the meantime, spray the back of a spoon with cooking spray (prevents the marshmallow from sticking to the spoon).
When the microwave is done, take the back of the spoon and gently spread the melted marshmallow over the top of the cupcake.
Sprinkle with crumbled graham crackers, and enjoy!
