OK, I give up. I need to break my healthy streak and give in to my chocolate craving. I tried. I really did. This one has a few steps but the result is so worth it. Chocolate cake, chocolate mousse, chocolate shell, and a sweet sauce. Oh, I almost forgot. Did I say there is coffee in there?? Save this and bring it out for special occasion. Mine is Sunday. Just Sunday… Enjoy!

Death by Chocolate Cake
For the cake and mousse:
- 1 18 .25- ounce box devil's food cake mix plus required ingredients
- 14 ounces bittersweet chocolate chopped
- 12 tablespoons 1 1/2 sticks
- unsalted butter diced
- 1/4 cup strong coffee
- 10 large eggs separated
- 1 1/2 cups plus 6 tablespoons sugar
- 1 teaspoon vanilla extract
- 1/2 teaspoon salt
- 2 cups cold heavy cream
For the shell and sauce:
- 12 ounces bittersweet chocolate chopped
- 3/4 cup heavy cream
- 5 tablespoons light corn syrup
- 2 tablespoons unsalted butter
- 1 1/2 cups cold heavy cream
- 1 tablespoon sugar
- 1 pint vanilla ice cream
Make the cake:
- Prepare the cake mix as the label directs for a 9-by-13-inch cake. Bake; cool slightly in the pan, then invert onto a rack to cool completely.
- Clean out the cake pan and line it with plastic wrap. Cut the cake in half lengthwise, then in thirds crosswise to make 6 rectangles. Using a serrated knife, slice each rectangle in half to make two layers. Arrange half of the pieces snugly in the cake pan. Crumble the remaining pieces and press tightly into 6 small balls; arrange 1 cake ball in the center of each cake rectangle in the pan.
Make the mousse:
- Heat the chocolate, butter, coffee and 1/4 cup water in a heatproof bowl set over a saucepan of simmering water (do not let the bowl touch the water), stirring, until melted. Remove the bowl from the pan; stir until cool. Reserve the simmering water. Fill a large bowl with ice water.
- Whisk the egg yolks, 1 1/2 cups sugar and 2 tablespoons water in a separate large heatproof bowl. Set the bowl over the saucepan of simmering water and whisk until pale yellow, 6 to 8 minutes. Add the chocolate-coffee mixture and the vanilla and whisk until combined, about 2 minutes. Remove the bowl from the pan and set in the bowl of ice water; whisk until slightly cool but not thick, about 4 minutes.
- Beat the egg whites and salt in a bowl with a mixer until foamy. Add 2 tablespoons sugar and beat until almost stiff; gently fold into the chocolate-yolk mixture to make a dark chocolate mousse. Spread 5 cups over the cake and cake balls. Freeze until firm on top, about 30 minutes.
- Beat the heavy cream and the remaining 4 tablespoons sugar until soft peaks form; fold into the remaining mousse. Remove the cake from the freezer; spread with the light chocolate mousse, cover with plastic wrap and freeze until firm, at least 6 hours or overnight.
Make the chocolate shell:
- Stir the chocolate, heavy cream and 4 tablespoons corn syrup in a heatproof bowl set over a saucepan of simmering water (do not let the bowl touch the water) until melted. A spoonful at a time, spread half of the shell mixture over the frozen mousse. Return to the freezer.
Make the chocolate sauce:
- Add the remaining 1 tablespoon corn syrup and the butter to the remaining chocolate shell mixture. Microwave 30 seconds, then stir until glossy.
To serve the cake:
- Beat the heavy cream with a mixer until foamy. Add the sugar and beat until soft peaks form. Remove the cake from the freezer; invert onto a baking sheet and unmold, then invert again onto a platter, chocolate shell-side up.
- Cut the cake in half lengthwise using a warm knife, then cut into thirds crosswise to make 6 rectangles; cut each rectangle in half diagonally to make 2 triangles. Top each triangle with whipped cream, ice cream and the prepared chocolate sauce.
