3/4 c. unsweetened cocoa powder
1/4 c. sugar
1/2 c. boiling water
1 (16 oz.) pkg. angel food cake mix
1 1/4 c. water
1 tbsp. instant coffee powder
1 1/2 c. skim milk
1 (1 1/2 oz.) pkg. whipped topping mix
1 (1.4 oz.) pkg. sugar-free instant chocolate pudding mix

Preheat oven to 350°F. Line a 10 x 15-inch jellyroll pan with waxed paper. Whisk together cocoa, sugar and boiling water. Cool to lukewarm. Prepare cake mix per package directions, using 1 1/4 cups water and adding cocoa mixture. Spread batter evenly in the pan.

Bake 20 minutes or until top looks dry. Invert onto a large wire rack. Remove the pan and waxed paper. Cool. In a medium bowl, dissolve coffee in milk. Add topping and pudding mixes. Beat on low speed until moistened. Beat at high speed until soft peaks form. Chill 5 minutes. Cut cake crosswise into thirds. Cover each layer with topping. Stack and chill 2 hours.
