1 pkg brownie mix for a 9x13 inch pan (I like Martha White Fudge)
1/2 cup prune puree (or applesauce)
1 egg
1/2 cup water

Preheat oven to 350 deg. Spray a 9x13 pan with cooking oil spray. Blend all ingredients until thoroughly mixed. Turn into prepared pan and bake according to pkg directions. Allow to cool before cutting into squares.
