- 1 box brownie mix, plus the ingredients to mix per instructions on box
- 1 roll of refrigerated chocolate chip cookie dough
Make brownies according to instructions on box, but do not bake. Place cupcake liners in two muffin tins and fill each liner about half way with the brownie mixture.
Slice cookie dough about ¼-inch thick. If using regular muffin tins, use half of the slice; for mini-muffin tins, use a quarter of a slice. Roll the piece of sliced cookie dough into a ball and place on top of each brownie muffin.
Bake muffins in a 350-degree oven for 12–15 minutes, depending on oven and size of muffin tins you use. Do not over bake. They are done when a toothpick comes out clean.
