These were amazing and fun to do with the kids! 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 Ohhhh! Sounds so good!!
