Instructions
For the Cake
- Prepare ½ package of cake mix according to the instructions on the box. The above ingredient measurements are for ½ box of Betty Crocker Devil's Food Cake, so be sure to use halved measurements for the appropriate ingredients if you use a different brand of cake mix. If your cake mix calls for 3 eggs, use 1 egg and 1 egg yolk as your halved measurement. Bake in a 9-inch springform pan according to the instructions (around 25 minutes) and let cool on a wire rack while you prepare the mousse.
For the Chocolate Mousse
- In a small bowl, combine the gelatin and cold water and bloom for 5-10 minutes.
- Meanwhile, place chocolate chips in a heatproof bowl. In a small saucepan set over medium-high heat, bring 1 cup of heavy cream to a simmer (between 112-115°F), then remove from the heat.
- Whisk in the bloomed gelatin and stir until completely dissolved. Pour mixture over the chocolate chips and whisk until melted and combined. Allow mixture to cool, stirring occasionally.
- In the bowl of a stand mixer fitted with the whisk attachment, or with a hand mixer in a large bowl, beat the remaining 2 cups of cream with the powdered sugar until stiff peaks form.
- Stir about ¼ cup of the whipped cream into the melted chocolate. Gently fold in the remaining whipped cream until fully incorporated.
- Spread the chocolate mousse evenly on top of the cooled cake while still inside the pan.
- Cover with plastic wrap and refrigerate for at least 8 hours or up to overnight.
For the Ganache
- Once the cake has chilled overnight, place the chocolate chips in a heatproof bowl. In a small saucepan set over medium-high heat, bring 1 cup of heavy cream to a simmer (between 112-115°F), then remove from the heat.
- Pour the warm cream over chocolate chips and allow to sit for 3-4 minutes, then whisk gently until smooth and shiny. Allow to cool until slightly thickened, then pour over the mousse.
- Cover and chill for 1 hour. Serve garnished with chocolate shavings and berries, if desired.
Notes
- Storage: Store chocolate mousse cake in an airtight container in the refrigerator for up to 5 days.
- Your mousse needs time overnight to sit before the ganache is poured on top. Do not try to rush this process!
- Devil's food cake or just regular chocolate cake are both great box mixes to use for this recipe.
- Heavy cream can NOT be substituted with whole milk, or anything else for that matter. Don't even try it!
