Dessert: Chocolate Mousse Crunch Cake

http://www.ourbestbites.com/2010/03/chocolate-mousse-crunch-cake.html

1 package Duncan Hines Devil's Food Cake
1 recipe (give or take a little) Chocolate Ganache
Crushed Heath bars or a bag of chocolate-covered Heath bits
1 tsp. unflavored gelatin
1 Tbsp. cold water
2 Tbsp. boiling water (just heat it in a small bowl in your microwave)
1/2 c. sugar
1/4 c. unsweetened cocoa powder
1 c. whipping cream
1 tsp. vanilla

Bake cake according to cake mix instructions in 2 8" round pans. Allow to cool and set aside. This can be done several days in advance; just freeze the cakes when you're done.

In a small bowl, combine gelatin and cold water and allow to stand for about 1 minute. While gelatin is softening, bring 2 Tbsp. water to a boil in the microwave. Whisk into the softened gelatin and allow to cool slightly.

In a medium mixing bowl, combine sugar, cocoa powder, whipping cream, and vanilla. Beat with an electric mixer until medium-stiff peaks form. Mix in gelatin mixture and refrigerate for 30 minutes.

Prepare ganache (if you haven't already) according to directions.

With a serrated knife, carefully slice the dome-iest part of each cake layer off so the layers are level. Place one layer on the serving plate and spread about 1/2 of the chocolate mousse over the cake. Sprinkle with Heath bits.

Place second layer on top of Heath bits.

Spoon ganache over the top layer, allowing it to drip down the sides. Mine was actually a little thicker here than I wanted--I could have warmed it up longer or added a little more heavy cream. Sprinkle with additional Heath bits
and refrigerate until ready to serve.
