Fudge Brownies

1 (18.25 ounce) box chocolate cake mix (any flavor chocolate)
1 small box instant chocolate pudding
1 1/2 cups milk
6 ounces chocolate chips

Combine all ingredients using a spoon or whisk (don't use a mixer). Spread in a greased jellyroll pan or 9 x 13-inch pan. Bake at 350 degrees F for 25 minutes (longer if using a 9 x 13-inch pan). For an even more fudgy taste, reduce the milk to 1 cup.
