Death by Chocolate

Step 1
Preheat the oven to 350 degrees F (175 degrees C). Grease and flour a 9×13-inch dish.

Step 2
Mix cake batter according to package directions, adding water, eggs, and oil as directed. Spread batter into the prepared dish.

Step 3
Bake in the preheated oven until a toothpick inserted into the center comes out clean, about 30 minutes. Cool and crumble.

Step 4
Make pudding according to package directions, adding milk as directed.

Step 5
Place 1/2 of the crumbled cake into a large trifle or other glass serving bowl. Pour 1/2 of the coffee over cake and spread 1/2 of the pudding on top. Cover with 1/2 of the whipped topping and sprinkle with 1/2 of the crushed candy bars. Repeat layers in the same order. Refrigerate until serving.
