Chocolate Oreo Dream Cake (made with a boxed Devils food cake mix!!) SO EASY! I used butter instead of oil, milk instead of water or sour cream, didn't use sour cream at all. I halved the filling recipe but still used 12 Oreos. Everyone loves this cake!
In a tall trifle-style glass bowl, make a layer of brownies on the bottom, then layer with about 1/3 of the chocolate mousse, sprinkle on some of the crushed Heath Bars. Layer about 1/3 of the cool whip. Again sprinkle with some crushed Heath Bars. Repeat layers until the bowl is full up to the top. Top with the remaining Heath Bar crumbles.
