1 box (18 1/4 oz) chocolate cake mix
1 orange, zested and juiced
2 pkgs (2.8 oz each) dark chocolate mousse mix
1 carton (12 oz) frozen whipped topping, thawed
Preheat oven to 350 degrees.
Prepare cake mix according to the package directions, adding 2 teaspoons of the orange zest. Divide batter into 3 8-inch round cake pans. Bake around 15 minutes or until a wooden toothpick inserted in the center comes out clean. Cool in pan about 5 minutes then transfer to wire racks to cool completely. Place both packages of mousse mix in a medium mixing bowl. Add 1/4 cup orange juice. Beat mixture for 2 minutes. Fold in the whipped topping. Chill frosting until ready to layer the cake. Put one layer on a serving plate. Top with 1 cup of the frosting. Add second layer and repeat, add third layer. Using the remaining frosting, completely frost the top and sides of the cake. If desired, use thinly sliced orange slices arranged in the center of the cake for garnish.
