Flourless Frozen Chocolate Mousse Cake

If you’re looking for a swoon worthy chocolate dessert, look no further and make this sublime Flourless Frozen Chocolate Mousse Cake.

This chocolate number started with a flourless chocolate cake base, topped by an incredibly rich and creamy mousse and iced with a glossy ganache. It was perfect for a friend facing back surgery and her chocoholic husband.

Frozen desserts are perfect for gifting as they don’t need to be eaten right away and are terrific for unexpected company or those pesty cravings! My girlfriend is a chocolate fanatic and I knew having slices of this dreamy frozen chocolate mousse cake in her freezer would brighten up a dreary day of rehab.

There are three layers of decadence in this frozen mousse cake: a flourless chocolate cake, a layer of dreamy mousse, and a topping of chocolate ganache! Each one is fabulous on its own, but together, they create a chocolate extravaganza!

I brought this cake to my friend, Candes, with a couple pre-cut slices for her and our other friends to sample at one of our knitting group meetings. Our hostess is gluten free so rarely gets to enjoy my treats. She was happy to indulge as was the rest of the crew.

I left a slice at home for my own chocolate taste tester—and this was unequivocally a hit across the board. I found this recipe on the blog of my dear blogger friend, Danielle. She and I cook from each other’s blogs each month, and when I spied this chocolate number on Hugs & Cookies XOXO, I knew it would bring sheer bliss to all who indulged.

I got an email from Candy only days after her surgery, requesting the recipe. Her husband told her it was the only chocolate cake she ever needed to make. And she clarified that it was most likely the only dessert she’d ever need to make! If you’re looking for a showstopping treat for the chocoholic in your life, you’ve found it.

If you want any chance of getting the mousse cake out of the springform pan, you’ll want to use non-stick foil to line it. I used two pieces placed perpendicular to each other so that all the inner surface was cover.
I did my best to press the foil tightly against the inside of the pan, but you’ll still see wrinkles and folds on the sides of the dessert when it’s unmolded. No one except the baker will notice this!
Do you know what a springform pan is? It’s used mainly for cheesecakes, but works great for any cakes. It has a removable base and a “collar” for the sides which can be released with a clip. It’s a must for this mousse cake.
I also like using this cake spatula for moving cakes and cheesecakes from the pan to the serving plate.
You will need to separate your eggs for the mousse. PRO-Tip: Remember that eggs separate easiest when cold, but egg whites whip best when at room temperature.
PRO-Tip: And note than any yolk that contaminates the egg whites (or any grease on the bowl or beaters) will prevent them from whipping into stiff peaks. It’s worth taking your time separating the eggs so none are wasted.
The cake layer will shrink as it cools, so the mousse layer invariably will be a little bit wider than the cake below.
To cut, I found using a long, sturdy bread knife worked well as it could straddle the whole cake. Warming the knife helps cut through a frozen dessert if needed.
You’ll want this dessert to sit out at room temperature after it’s sliced and placed on dessert plates. It slices cleanly when frozen solid, but let it soften for a few minutes to make for easier indulging.
Did you know that cold inhibits a dish’s flavor? So for desserts like ice cream, you need to bump up the flavorings a bit.

Instructions

1. Preheat the oven to 350°F (175°C). Line the inside of a 9-inch springform pan with nonstick foil, ensuring it covers all surfaces. Wrap a piece of foil around the outside of the pan as well.
2. For the cake: Melt 2 sticks of butter and 12 ounces of chopped semisweet chocolate in the microwave, stirring until smooth. Allow to cool slightly.
3. In a large bowl, whisk together 6 large eggs, 1 cup sugar, and 1 tablespoon vanilla extract until well combined. Gradually add the melted chocolate mixture, stirring until smooth.
4. Pour the batter into the prepared springform pan and bake for 25-30 minutes, or until the cake is set and the top looks dry. Let cool completely in the pan on a wire rack.
5. For the mousse: Melt 4 tablespoons of butter and 10 ounces of semisweet chocolate in the microwave, stirring until smooth. Allow to cool slightly.
6. In a separate bowl, beat 3 egg yolks with 1/4 cup sugar until pale and thick. Gradually add the melted chocolate mixture, stirring until smooth.
7. In another bowl, whip 1 cup of heavy cream until soft peaks form. Gently fold the whipped cream into the chocolate mixture until combined.
8. In a clean bowl, beat the 3 egg whites until stiff peaks form. Gently fold into the chocolate mixture until no streaks remain.
9. Spread the mousse over the cooled cake layer in the springform pan. Cover and freeze until firm, at least 4 hours or overnight.
10. For the ganache: Heat 1 cup of heavy cream in a saucepan until it just begins to simmer. Remove from heat and add 8 ounces of semisweet chocolate, stirring until smooth and glossy.
11. Remove the cake from the freezer and pour the ganache over the mousse layer, spreading evenly. Return to the freezer until the ganache is set.
12. To serve, remove the cake from the springform pan and let it sit at room temperature for a few minutes before slicing. Use a warm knife for clean cuts.

Notes

Use non-stick foil to line the springform pan for easy removal. Separate eggs while cold, but whip egg whites at room temperature for best results. Allow the cake to sit at room temperature for a few minutes before serving to enhance flavor. A warm knife helps in slicing the frozen cake cleanly.
