Preheat oven to 350; smoosh 1.5 squares of break-apart refrigerated cookie dough into the bottom of each well. Place Reese cup upside down on top of cookie dough (or an Oreo!). Top with prepared box brownie mix, filling 3/4 full. Bake for 18 minutes! HEAVEN.
I used this recipe for some chocolate cupcakes last week and they were dense, moist, and SO much better than the regular! I still prefer baking cupcakes by scratch, but if I ever use box again, I will do this again! ~Christine
