You could save time by using store-bought mixes for your chocolate layer cake, the mousse, and the ganache, BUT you might not want to, as the homemade versions taste SO much richer!

Easy instructions on How to Make Chocolate Mousse and How to Make Chocolate Ganache are given below on this page.

Chocolate Mousse Cake


You'll need one 9-inch round chocolate cake, cooled and cut into 2 layers; or, a couple of 9-inch cakes, if you prefer a thicker layer cake for more servings.

1 batch of chocolate mousse, set and chilled (recipe below)
2 cups stabilized whipped cream
1 batch of chocolate ganache (recipe below)
3 Hershey's Skor® chocolate bars, crumbled
(Canadians can substitute Crispy Crunch® bars)
Fresh strawberries for garnish

Assembly Instructions for the homemade Chocolate Ganache Mousse Cake Recipe:

Begin by placing your first cake layer on a cake board or plate and top with the chocolate mousse layer.

Add the second cake layer and top with the whipped cream, making sure you set aside enough whipped cream for the piped decoration on top.

Spoon some of the chocolate ganache over the whipped cream after first making sure your ganache is not too warm, or it will melt your whipped cream.

Then simply spoon and drizzle the ganache all over the cake, letting it drip and trickle down the sides.

Don't worry if it gets a bit messy looking, as you can always wipe your cake board with a cloth later before serving.

Next, chill your Skor® or Crispy Crunch® bars in the refrigerator, then place them in a plastic bag and crumble them into small pieces by gently tapping them with a hammer or the bottom end of a glass bottle.

Place the whipping cream in your mixing bowl and beat until peaks start to form. Add the sugar, cocoa, and vanilla, and continue beating until stiff peaks form.

Easy Chocolate Ganache Recipe

Here's how to make homemade ganache the easy way. You'll love its decadent taste, yet it's a much creamier ganache than most, so feel free to adjust the quantity of chocolate to match your preference.

It's the perfect ganache to use with the homemade Chocolate Ganache Mousse Cake recipe. And, it's also delicious as a topping on your favorite ice cream sundae treat.

How to Make Chocolate Ganache


6 ounces semi-sweet chocolate (6 wrapped squares)
3/4 cup of heavy whipping cream

Break the chocolate squares into small pieces and place them in a double boiler to melt, while stirring occasionally as the chocolate softens.

A heatproof bowl set in the opening of a saucepan will serve as a double boiler in a pinch. Simmer about an inch of water in the saucepan, making sure the water does not touch the bottom of the bowl.

You may add a few chocolate chips if you don't have enough baking squares. If you prefer to use all chocolate chips instead of squares, you'll need 1 cupful.

Now add the heavy cream to the melted chocolate and heat for about 2 minutes while constantly stirring.

If the chocolate hasn't completely blended with the cream, continue heating and stirring the mixture for another minute or so.

You will know your ganache is ready when the chocolate and cream are thoroughly combined, and you have a smooth mixture that's easy to pour.

Use your ganache immediately in your chocolate ganache mousse cake recipe or store it in the refrigerator for later and reheat it to get the perfect consistency required for use as a topping.

About the Chocolate Bars

Skor® Bar

Skor® bars were first produced and sold by The Hershey Company in 1981. Skor is Swedish for shoes, believe it or not, and the bar consists of a crispy butter toffee center covered in milk chocolate. They are popular everywhere.

Crispy Crunch Bar

Canadians might choose to substitute Crispy Crunch® bars, a Canadian favorite since 1923. Invented by a Neilson® employee in 1912, these delicious Canadian chocolate bars are made by Cadbury® and feature a crunchy, flaky, peanut layered, sponge toffee center covered in milk chocolate.

Apologies to our American friends, but Crispy Crunch bars are not sold in the United States. Sorry!

Either of the above bars is delicious when used as a crumbled topping in your Chocolate Ganache Mousse Cake recipe.
