Chocolate Mouse Cake

The cake below was my attempt at a topsy turvey cake.  I made the bow and all the flowers...what fun this was.  I used the chocolate mouse cake recipe because it is everyone's favorite cake.

The cake:
2 cups all-purpose flour
2 cups sugar
3/4 cup unsweetened cocoa powder
1 1/2 tsp baking powder
1 1/2 tsp baking soda
3/4 tsp salt
1 cup milk
1 cup express coffee or very strong coffee (hot)
3/4 cup vegetable oil (do not substitute for a low cal oil)
2 large eggs
Preheat oven to 350 degrees. Grease and flour 3- 9 inch round cakepans.
In large bowl, combine flour, sugar, cocoa, baking powder, baking soda, and salt and mix well. Add milk, Oil, and eggs. Beat at med speed till
mixed well. Add hot coffee and starting on low beat till mixed in and then turn back to medium and mix till smooth.
Pour mixture evenly into prepared pans and bake for 23 to 25 minutes, or until a wooden pick inserted in the center comes out clean. Let
cakes cool completely on wire racks. Using a serrated knife, cut cake layers in half horizontally to make 6 layers. Place 1 layer, cut side up, on a
cakeplate; spread with one-fifth of the Chocolate Mousse. Repeat procedure with remaining cake layers and mousse. Freeze cake for 1 hour.
Spread chocolate Fudge Frosting evenly over top and sides of cake. You can garnish sides of cake with grated chocolate and top with chocolate
curls for a nice touch.
