Preheat oven to 350. Mix box cake mix, milk, oil & eggs. Crush 12 Oreos & add to mix. Spray 13x9 pan with baking spray. Bake for 30 min.

Once cake is done, take a fork and place holes all over the cake. Let cool for 30 minutes. Slowly cover with milk mixture. Cover & refrigerate for 2 or more hours. Add your favorite frosting or whipped cream and add the rest of the crushed Oreos, saving 2-4 to place on top.
