The boys and I made this dessert the other day and it was delicious! It was super easy too. One of those desserts that I can have my 3 and 5-year-old help me with. I used some store bought cookie dough and spread it out on the bottom of a greased 9x13in pan. You could also use your normal cookie dough recipe… I was just being a little lazy. Then layered double stuffed oreos on top and then spread brownie batter on top of the cookies. I baked it in the oven for about 35-40 minutes.
