Preheat oven to 350 degrees f. Spray 11x7 baking pan with nonstick spray. In a large bowl, combine cake mix, oil and egg. Add the milk slowly. Fold in the chopped cookie pieces and sprinkles, reserving some for a topping. Pour into prepared baking pan, sprinkle a few more sprinkles and crushed Oreos on top. Bake for 25-30 minutes until edges are just turning brown. Cool for at least 30 minutes so the center sets, before cutting into squares. |
