Ingredients
CHOCOLATE CAKE
- 1/4 cup (56g) unsalted butter, room temperature
- 1/2 cup (104g) sugar
- 1/4 cup (58g) sour cream, room temperature
- 1/2 tsp vanilla extract
- 2 egg whites, room temperature
- 1/2 cup + 2 tbsp (81g) all purpose flour
- 1/4 cup + 2 tbsp (43g) Hershey’s special dark cocoa
- 1 1/8 tsp baking powder
- 1/4 tsp salt
- 1/4 cup (60ml) milk, room temperature
- 2 tbsp water, room temperature
CHOCOLATE FUDGE
- 6 oz (170g) semi sweet chocolate chips
- 2 tbsp (30ml) light corn syrup
- 1/2 tsp vanilla extract
- 1/2 cup (120ml) heavy whipping cream
CHOCOLATE MOUSSE
- 4 large egg yolks
- 1/4 cup (52g) sugar
- 1 3/4 cups (420ml) heavy whipping cream, divided
- 8 oz (227g) semi sweet chocolate chips
- 3/4 cup (86g) powdered sugar
WHITE CHOCOLATE MOUSSE
- 1 1/4 tsp unflavored powdered gelatin
- 1 1/2 tbsp (23ml) water
- 9 ounces (255g) white chocolate chips
- 1 3/4 cups (420ml) heavy whipping cream, cold, divided
- 1/3 cup (38g) powdered sugar
Instructions
1. Preheat oven to 350°F (176°C) and prepare an 8 inch cake pan with parchment paper in the bottom and grease the sides.
2. In a large mixing bowl, cream the butter and sugar together until light in color and fluffy, about 3-4 minutes. Do not skimp on the amount of creaming time.
3. Add sour cream and vanilla extract mix until well combined.
4. Add egg whites one at a time, mixing until well combined after each. Scrape down the sides of the bowl as needed to be sure all ingredients are well incorporated.
5. Combine dry ingredients in a separate bowl, then combine milk and water in a small measuring cup.
6. Add half of the dry ingredients to the batter and mix until well combined. Add the milk mixture and mix until well combined. Add remaining dry ingredients and mix until well combined.
7. Spread the batter evenly into the prepared pan and bake for 19-21 minutes, or until a toothpick inserted in the middle comes out with a few crumbs.
8. Remove cakes from oven and allow to cool for 3-4 minutes, then remove to cooling rack to cool completely.
9. One the cake is cooled, prepare the cake pan for layering. To set up your cake pan, line an 8×3 inch springform pan with parchment paper that goes about 2 inches above the top edge of the pan. A springform pan is best so that you can easily remove the cake once it’s been assembled. If you only have a regular 8×3 inch cake pan, line the cake pan with plastic wrap (which can later be used to lift your cake out of the pan once it’s assembled), then add the parchment paper. You can also place a cardboard cake circle in the bottom of the pan, on top of the clear wrap. In lou of using a cake pan to build the cake, you could also use cake collars.
10. Cut the dome off of the cake, then place it in your pan or cake collar.
11. To make the fudge layer, add the chocolate chips, corn syrup and vanilla extract to a medium heat-proof bowl.
12. Heat the heavy whipping cream until it just starts to boil, then pour it over the chocolate chips. Cover the bowl with clear wrap and allow to sit for 3-5 minutes, then whisk until smooth.
13. Pour the chocolate on top of the cake and spread into an even layer. Place the cake in the fridge while the ganache firms, about 1 hour.
TO MAKE THE CHOCOLATE MOUSSE:
1. Combine egg yolks, sugar and 1/2 cup (120ml) of heavy whipping cream in the top of a double boiler. If you don’t have a double boiler, you can use a mixing bowl set over a pot with simmering water in it. I use my mixer bowl. Do not let the water boil, or it will be too hot. To ensure that the steam cooking the eggs doesn’t get too hot, occasionally lift the bowl to release the steam.
2. Cook mixture, whisking constantly. The mixture will thin out at first, then begin to thicken. The egg mixture will be ready when is has thickened, lightened in color and has more volume. It should take about 7-10 minutes and reach 160°F (71°C). Do not boil. When done, remove egg mixture from heat and set aside.
3. Place the chocolate chips for mousse in a medium sized bowl and melt in the microwave in intervals of about 10-15 seconds, stirring well between each interval, until smooth. You could also melt them in a double boiler, if you prefer.
4. Vigorously whisk the egg mixture into the melted chocolate until smooth. Set aside to cool to about room temperature.
5. In another bowl, whip remaining 1 1/4 cups (300ml) of heavy whipping cream and powdered sugar until stiff peaks form.
6. Fold about a ¼ cup of the whipped cream into the chocolate mixture until , then fold about a 1/4 of the chocolate mixture into the whipped cream. Slowly fold the remaining chocolate mixture into the whipped cream.
7. Spread the chocolate mousse into an even layer on top of the chocolate fudge. Refrigerate for about an hour.
TO MAKE THE WHITE CHOCOLATE MOUSSE:
1. In a small bowl, sprinkle the powdered gelatin over the water, making sure the powder is all touching water. Let stand for about 5 minutes.
2. Place the white chocolate chips in a medium glass bowl. Microwave 1/2 cup (120ml) of heavy cream in a medium measuring cup until it comes to a boil.
3. Add the gelatin mixture to the hot heavy cream mixture and whisk until the gelatin is dissolved.
4. Pour the hot cream over the white chocolate chips and let stand, covered, for 3-5 minutes. Whisk the white chocolate mixture until the chocolate is melted and the mixture is smooth. If it doesn’t completely melt, microwave in 10-15 second intervals, whisking well between each, until smooth. Set aside to cool to about room temperature.
5. Whip remaining 1 1/4 cups (300ml) heavy cream and powdered sugar at high speed with a mixer until stiff peaks form.
6. Gently fold about a third of the cooled white chocolate mixture into the whipped cream until combined. Add the second third of the cooled white chocolate and gently fold into the whipped cream. Add the remaining white chocolate and fold together until completely combined.
7. Spread the white chocolate mousse into an even layer on top of the chocolate mousse. Refrigerate until completely firm, at least 3-4 hours.
TO FINISH OFF THE CAKE:
1. Once firm, remove the cake from the pan or remove the cake collar from the sides. If needed, smooth the sides of the cake using an offset spatula, and place cake on a serving plate.
2. Finish off the cake with chocolate curls and a sprinkle of cocoa powder. Keep cake refrigerated until ready to serve.

Texture & Flavor Magic in Every Layer
Why Texture Is the Secret Star of This Triple Chocolate Mousse Cake
It’s not just a dessert; the Triple Chocolate Mousse Cake is a conversation starter.
The genius of a triple chocolate mousse cake isn’t just in its flavor—it’s in the way each layer contrasts and complements the next. The journey starts at the bottom with a soft, dark chocolate cake that has just the right crumb. It’s moist, but structured enough to hold the decadent layers that follow. This isn’t a spongy throwaway base—it’s part of the full experience.
Next, we pour on a thick, shiny chocolate fudge—almost like ganache, but silkier and not too sweet. It brings depth and a slight chew, locking in moisture and adding richness. By the time you get to the chocolate mousse layer, you’re floating. It’s airy but still holds shape, creating a pillowy contrast against the fudge. And just when you think it’s all done, the white chocolate mousse comes in like a whisper of sweetness and light. It’s creamy, slightly floral from the white chocolate, and balances the darker layers beneath.
Every slice of Triple Chocolate Mousse Cake melts in your mouth, providing a truly decadent experience.
Every bite delivers a perfect blend: soft cake, smooth fudge, and fluffy mousse.
The gentle chill from refrigeration makes it stand out.
Unlike warm desserts, this one is refreshing, elegant, and totally satisfying.
How to Balance Bitterness, Sweetness, and Creaminess
One of the most common mousse cake mistakes? Making it too sweet. This recipe solves that by using Hershey’s Special Dark cocoa in the cake base and semi-sweet chocolate in both mousse and fudge. The result is a mellow bitterness that keeps the dessert grown-up while still indulgent.
The white chocolate mousse isn’t cloying either. It’s sweet, yes—but it’s also tempered with cold whipping cream and a touch of gelatin to give it body without overwhelming the palate. This balance is crucial, especially if you’re serving it after a heavy meal.
A good mousse cake should have contrast. Each layer here brings something different: rich base, chewy center, smooth rise, creamy top. And the best part? You can build it all ahead of time, letting the flavors meld in the fridge overnight.

Mastering the Mousse – Tips for Smooth, Stable Layers
How to Avoid a Runny or Grainy Mousse
When in doubt, serve Triple Chocolate Mousse Cake to wow your guests every time.
If you’ve ever tried to make mousse and ended up with soup or lumps, you’re not alone.Mastering the perfect temperature and folding technique is the key to success.For both the chocolate and white chocolate mousse layers, your goal is an airy yet firm texture. That means your chocolate should be fully melted but not hot when you add the whipped cream. If it’s too warm, you’ll deflate the cream or even curdle it. Too cool, and the mixture becomes stiff and streaky.
Also crucial: use cold heavy cream and beat it to stiff peaks—not soft. You want structure that can support itself when layered over the fudge. Whip with powdered sugar to create a light sweetness and extra body. And always fold, never stir—cut through the center of the bowl, turn, and repeat to preserve air.
A stabilizing agent like unflavored gelatin, used in the white chocolate mousse, helps hold the shape without making it rubbery. Just make sure the gelatin is dissolved completely before mixing it into your melted chocolate.
Build and Chill for Perfect Assembly
Once the cake and fudge are in the pan, chilling time becomes your best friend. Each mousse layer needs to set before adding the next—about an hour each in the fridge. Rushing this step causes layers to bleed into each other, losing that beautiful definition when sliced.
With Triple Chocolate Mousse Cake, you can impress your friends and family without fuss.
For clean lines and smooth edges, use a springform pan lined with parchment or acetate cake collars. Not only do they help release the cake cleanly, they also create those bakery-level sides. When it’s time to unmold, a quick warm towel around the edges (or gentle run of a warm spatula) helps you get a polished finish.
This Triple Chocolate Mousse Cake can be varied with different toppings to suit your taste.
Want to level up? Decorate the top with chocolate curls, shavings, or even gold leaf for an elegant finish. I also love dusting with a little cocoa powder to echo the richness below.

How to Customize the Triple Chocolate Mousse Cake for Any Diet
While the original version is rich and decadent, it’s surprisingly easy to adapt this Triple Chocolate Mousse Cake to suit various diets. Whether you’re baking for a gluten-free guest, watching sugar intake, or avoiding dairy, a few smart swaps make this dessert more inclusive without compromising taste.
For gluten-free: Replace the all-purpose flour in the cake base with a high-quality 1:1 gluten-free baking flour.Be sure to use baking powder that’s labeled gluten-free as well.The mousse layers are naturally gluten-free, so that’s one less thing to worry about.
For dairy-free: Substitute the heavy cream with coconut cream (chilled and whipped), and use dairy-free chocolate chips. The fudge layer can also be made with almond or oat milk cream alternatives. Just note—these swaps will slightly change the flavor profile, but the result is still luscious.
For lower sugar: Use semi-sweet or bittersweet chocolate with at least 70% cacao to reduce overall sugar content, and swap powdered sugar with a low-glycemic sweetener like powdered monk fruit or erythritol.
No matter your modifications, make sure to taste as you go—especially when using alternative chocolates or creams. Some may be more bitter or less stable, so adjust sweetness and consistency accordingly.

Before we wrap up, let’s answer your most-asked questions in the FAQ section.
Frequently Asked Questions About Triple Chocolate Mousse Cake
Can chocolate mousse be used as a cake filling?
Absolutely! Chocolate mousse is a fantastic option for cake filling. It’s light, creamy, and, when stabilized correctly, it holds its form beautifully. In this recipe, it does more than fill—it becomes a full layer, adding both structure and a luxurious, airy texture. Just be sure it’s fully chilled for clean slicing.
What is the difference between a mousse cake and a regular cake?
The key difference lies in texture and preparation. Traditional cakes are typically made with baked layers and frosted with creams or icings. Mousse cakes, on the other hand, rely on fluffy, whipped mousse layers that are set by chilling. The result is a smoother, lighter dessert often served cold—perfect for sophisticated occasions.
What was Julia Child’s favorite cake?
Julia Child had a fondness for rich, French-inspired treats. One of her most beloved cakes was the Reine de Saba—a moist chocolate and almond cake with a tender center and glossy dark chocolate glaze. Like mousse cake, it’s all about deep flavor and refined texture.
