Ingredients for SUMMER DECADENT TRIPLE CHOCOLATE MOUSSE CAKE
Creating this SUMMER DECADENT TRIPLE CHOCOLATE MOUSSE CAKE starts with a few simple yet delightful ingredients. For the cake base, you’ll need all-purpose flour, unsweetened cocoa powder, baking powder, and a pinch of salt. The moist texture comes from eggs, sugar, vegetable oil, milk, and a dash of vanilla extract.
The star, of course, is the chocolate. Both semi-sweet or dark chocolate chips and white chocolate chips will elevate your mousse layers. And don’t forget the heavy cream—cold and whipped to perfection is crucial for those luscious mousses. For an optional touch, you can garnish with chocolate curls for that extra wow!

How to Make SUMMER DECADENT TRIPLE CHOCOLATE MOUSSE CAKE
Step 1 – Prepare the Cake Base
Let’s start with the foundation of our cake—the chocolate cake base. Preheat your oven to 350°F (175°C) and prepare an 8-inch round or springform pan by greasing it and lining the bottom with parchment paper. In a mixing bowl, whisk together the all-purpose flour, cocoa powder, baking powder, and salt. In another bowl, beat the eggs and granulated sugar until they turn pale and fluffy. Add in the oil, milk, and vanilla extract, mixing until everything is incorporated. Now, gently stir in your dry ingredients until the batter is smooth. Pour this delicious mixture into the prepared pan and bake for about 18 to 20 minutes, or until a toothpick comes out clean. Once baked, let it cool completely.
Step 2 – Make the Dark Chocolate Mousse
Now for the rich dark chocolate mousse—a true star of the show! Begin by melting the dark chocolate chips. You can do this in the microwave, heating in 15-second bursts, or using a double boiler. Let that cool for a few minutes while you whip some cold heavy cream. In a large bowl, beat the heavy cream with half a teaspoon of vanilla extract until stiff peaks form. Then, gently fold the whipped cream into the melted chocolate. It’s crucial to do this gently—keep that airy texture! Once smooth, spread this layer generously over the cooled chocolate cake base. Pop it in the fridge for 30 minutes to set.
Step 3 – Create the White Chocolate Mousse
Next up, we’ll make the heavenly white chocolate mousse. Melt the white chocolate chips in a similar fashion as the dark chocolate, and let it cool slightly. In a separate bowl, whip more heavy cream with the remaining vanilla extract until stiff peaks form. Once the melted white chocolate has cooled, fold it into your whipped cream carefully. The key is to be gentle again—nobody wants a deflated mousse! Once combined, spread this luscious white chocolate mousse over the dark mousse layer. Give it another chill in the fridge for at least 30 minutes until nicely set.
Step 4 – Assemble the Cake
Assembling is where the fun really happens! Once the white chocolate mousse is firm, remove the cake from the fridge. Now, let’s finish it off! You can whip up some more heavy cream with powdered sugar until you achieve those lovely stiff peaks once again. Spread or pipe this whipped cream on top of the white chocolate mousse layer. For that gorgeous finish, garnish with chocolate curls or shavings if you’re feeling fancy. It adds a beautiful touch, doesn’t it?
Step 5 – Finish and Serve
It’s almost time to indulge! To serve, refrigerate your cake for at least 2 to 4 hours, allowing it to set properly. When you’re ready to slice into your masterpiece, here’s a little secret: dip your knife in hot water and wipe it between cuts for cleaner slices. Trust me, it makes a world of difference! Finally, plate it up with some extra chocolate shavings on the side, and watch everyone’s faces light up. There’s nothing like sharing a slice of this SUMMER DECADENT TRIPLE CHOCOLATE MOUSSE CAKE with friends and family!
