The official title of this dessert,the recipe for which I cut out of a magazine, is "Jell-O and Cool Whip Easy Chocolate Trifle," but my niece simplified it at our family 4th of July get-together as "Brownie Trifle." [p.s. it wouldn't let me put "1 box of brownie mix" in the ingredients, but that's what you need. I like Duncan Hines, myself.]This dessert was absolutely the hit of the party. We had ages 2-72 in the house, and everyone LOVED it. Super easy to make, and can be as high or low fat as you'd like. When I told my mom after the fact that I'd used skim milk in the pudding and fat-free Cool Whip, she was totally stunned because people were lining up for second helpings. Prep and cooking time sound high, but the "cooking time" is the chill time and the time it takes the brownies to come out of the oven; "prep time" would be the time to make the brownie mix--10 minutes--and the time to make the pudding--about 10 minutes. The milk, water, eggs, and vegetable oil are for the pudding and brownies, but the ingredient list wouldn't quite let me put that, so there it is then.
