I know I didn't turn out the most beautiful cake in the world but it was absolutely wonderful. I made this a few months ago for a family event but ended up taking it in to work instead. Everyone asked for the recipe! The mousse in the middle was super easy to make. It truly surprised me because I didn't know how it would work at first. I didn't use as much toffee chips as the recipe called for and will probably add in more the next time I make it. I also didn't make a ganache ( I was making this for my mom and she doesn't like ganache) for the top but made a frosting like The Pioneer Woman's frosting for the Best Chocolate Sheet Cake Ever.
Chocolate Mousse Crunch Cake
Recipe Adapted from Our Best Bites
1 package Devil's Food Cake Mix
Crushed Heath bars (or a bag of toffee bits from the baking aisle)
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
Chocolate Frosting (adapted from this recipe)
1 stick Butter
2 Tablespoons (heaping) Cocoa
3 Tablespoons Milk
1 teaspoon Vanilla
2 Cups Powdered Sugar
Bake cake mix according to instructions on the box and bake in 2 8" round pans. Cool cakes completely before proceeding with the next steps.
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.
Place one layer on the serving plate and spread about 1/2 of the chocolate mousse over the cake. Sprinkle with Heath bits. Place the next layer of cake on top of the mousse layer and then pour the cooled chocolate frosting on top. Cake will need to be refrigerated but it probably won't last that long!!
