Got this from something Prevention magazine sent me to get me to buy something! Since I used to be in Weight Watcher's I have learned a box of Angel Food Cake mix can be the basis for many delicious, and much lower calorie dessert treats. This goes well at the potlucks, even if they don't realize it is a reduced calorie treat. It does need to chill in the fridge for at least two hours before serving. Each slice is 261 calories.
Preheat oven to 350 degrees; Line a 10x15" jelly-roll pan with parchment paper
Whisk together cocoa, sugar and boiling water. Cool to lukewarm.
Prepare cake mix per package directions, using 1-1/4 cup water and adding cocoa mixture; spread batter evenly in the pan; bake 20 minutes or until top looks dry; Invert onto large wire rack; remove the pan, and paper. Cool
In medium bowl, dissolve coffee in milk; topping and pudding mixes; Beat on low speed until all is moistened; Beat until soft peaks form; chill 5 minutes.
Cut cake crosswise into thirds; cover each layer with topping. Stack; chill for 2 hours before serving.
