How would you adapt a brownie recipe to a two-bite cupcake size?
Depending on the size of the cupcake tin you may have to increase or decrease the cooking times and temperature. My favorite "brownie disguised as a cupcake" recipe is from Paula Deen - http://www.foodnetwork.com/recipes/paula-deen/peanut-butter-brownie-cupcakes-recipe/index.html
