Step‑by‑Step Instructions for Tuxedo Cake – Triple Chocolate Mousse Cake
Step 1: Preheat and Prepare Cake Pans
Preheat your oven to 350°F (175°C). Grease two 9-inch round cake pans with butter or non-stick spray, then line the bottom with parchment paper for easy release. In a large mixing bowl, sift together the dry ingredients: all-purpose flour, sugar, cocoa powder, baking powder, baking soda, and a pinch of salt until blended.
Step 2: Mix Wet Ingredients
In a separate bowl, whisk together the wet ingredients: whole milk, large eggs, sour cream, vegetable oil, espresso powder, and vanilla extract until smooth. Gradually combine the dry and wet mixtures, stirring gently. Next, add in the hot water to create a batter that is smooth and glossy, ensuring no lumps remain.
Step 3: Bake the Cake Layers
Divide the cake batter evenly between the prepared cake pans, smoothing the tops with a spatula. Place the pans in the oven and bake for 30-35 minutes, or until a toothpick inserted in the center comes out clean. Once baked, allow the cakes to cool in the pans for about 10 minutes before transferring them to wire racks to cool completely.
Step 4: Prepare the Dark Chocolate Mousse
As the cake cools, start on the dark chocolate mousse. In a saucepan, heat 1 cup of heavy cream over medium heat until it simmers. In a mixing bowl, whisk egg yolks with sugar and cornstarch, then slowly pour in the hot cream, whisking constantly to temper the yolks. Return the mixture to heat and stir until it thickens.
Step 5: Add Dark Chocolate and Whipped Cream
Remove the thickened mixture from heat, divide it into two bowls, and fold melted dark chocolate into one half. For the rest, fold in half of the whipped cream gently, taking care not to deflate it. This creamy dark chocolate mousse will be perfect for layering on the cake later.
Step 6: Prepare the White Chocolate Mousse
Using the same method, repeat the process for the white chocolate mousse. Heat another cup of heavy cream, temper the egg yolks as before, then pour over the white chocolate, stirring until smooth. Finally, fold in the remaining whipped cream to create a fluffy texture.
Step 7: Assemble the Cake Layers
Once the cake layers are completely cool, place one layer on a serving plate. Spread a generous layer of the dark chocolate mousse on top, smoothing it with a spatula. Carefully place the second layer of cake on top, and then spread a layer of white chocolate mousse, creating a delightful contrast.
Step 8: Chill the Assembled Cake
Cover the cake with plastic wrap and refrigerate for at least 2 hours to allow the mousses to set and meld together. This chilling period is crucial for achieving the perfect texture in your luxurious Tuxedo Cake.
Step 9: Prepare the Ganache
While the cake chills, make the ganache. In a small saucepan, heat the remaining cup of heavy cream until it simmers. Pour the hot cream over the milk chocolate in a bowl and stir gently until combined and smooth, creating a luscious glaze for your cake.
Step 10: Glaze the Cake
Once the cake has chilled for the required time, carefully pour the ganache over the top, allowing it to drip down the sides for an elegant finish. Let the ganache set for about 10 minutes at room temperature before slicing and serving your glorious Triple Chocolate Mousse Cake.

Expert Tips for Triple Chocolate Mousse Cake
-
Choose Quality Chocolate: Use high-quality chocolate for the best flavor. Cheap chocolate can compromise the mousse’s rich taste and overall enjoyment.
-
Gelatin for Stability: If you prefer your mousses to hold together better, consider adding unflavored gelatin when making the dark and white chocolate mousses. This helps maintain structure when serving.
-
Chill Thoroughly: Allow the assembled cake to chill for at least 2 hours, preferably longer. This setting time is crucial for the mousses to firm up nicely, enhancing the final texture.
-
Warm Knife for Slicing: For clean slices when cutting your cake, dip a knife in warm water and wipe it dry before each cut. This technique keeps the layers intact and visually appealing.
-
Don’t Overmix: When folding in whipped cream, do it gently. Overmixing will deflate the mousse, reducing its light, airy texture that makes the Triple Chocolate Mousse Cake so divine!
-
Garnish Creatively: For an extra special touch, consider garnishing with fresh berries or chocolate shavings. This adds both color and fresh flavor, making your cake even more irresistible!
How to Store and Freeze Triple Chocolate Mousse Cake
Fridge: Keep your cake stored in the refrigerator covered with plastic wrap touching the surface to prevent the mousses from forming a crust. It will stay fresh for up to 3 days.
Freezer: If you have leftovers, you can freeze individual slices wrapped tightly in plastic wrap followed by aluminum foil for up to 3 months. This makes for a perfect treat later!
Thawing: To enjoy frozen slices, simply transfer them to the fridge and let them defrost overnight for the best texture or leave them at room temperature for a couple of hours before serving.
Reheating: If you prefer to warm your cake slightly, microwave each slice for about 10-15 seconds. Enjoy the indulgent flavors of this Triple Chocolate Mousse Cake!
Make Ahead Options
These Triple Chocolate Mousse Cake layers are perfect for meal prep enthusiasts looking to save time! You can prepare the cake layers up to 24 hours in advance; simply cool them completely, wrap tightly in plastic wrap, and refrigerate to keep them moist. Both chocolate mousses can be made up to 3 days ahead, as they actually improve in flavor when given time to chill. Just store them in airtight containers in the fridge. When ready to serve, assemble the cake by layering the cakes with the chilled mousses and drizzle the ganache on top. This way, you’ll have a stunning dessert with minimal effort, ready to impress your guests!

Tuxedo Cake – Triple Chocolate Mousse Cake Recipe FAQs
How can I tell if my ingredients, like eggs and milk, are fresh?
You can check the freshness of eggs by placing them in a bowl of water; fresh eggs will sink, while older eggs float. For milk, look for a sell-by date and give it a sniff—sour smell means it’s past its prime. If you’re unsure, always err on the side of caution!
What’s the best way to store leftover Triple Chocolate Mousse Cake?
Absolutely! Cover the cake tightly with plastic wrap, ensuring it touches the mousse to avoid any crust formation. Store it in the refrigerator for up to 3 days. For longer storage, consider freezing individual slices wrapped in plastic followed by foil to seal out air.
Can I freeze the Triple Chocolate Mousse Cake, and if so, how?
Yes, you can freeze it! First, ensure the cake has cooled completely. Slice it into individual pieces, then wrap each slice in plastic wrap, followed by aluminum foil. This can keep your cake fresh for up to 3 months! When you’re ready to enjoy, just thaw it in the fridge overnight or let it sit at room temperature for a couple of hours before serving.
What should I do if my mousse doesn’t set properly?
If your mousse doesn’t set, it could be under-whipped or not chilled long enough. For a perfect outcome, ensure that the whipped cream is whipped to soft peaks before folding it into your chocolate mixture. Additionally, make sure to chill the assembled cake for at least 2 hours to allow the mousse to firm up properly.
Are there any allergy considerations I should be aware of when making this cake?
Definitely! For those with gluten sensitivities, substitute all-purpose flour with almond flour for a gluten-free alternative. To make this a dairy-free dessert, swap heavy cream for coconut cream and choose dairy-free chocolate. Always check ingredient labels for allergens if you’re sharing with friends or family who might have dietary restrictions.
Can I use a different type of chocolate for the mousse?
Very much! While dark, milk, and white chocolates all create that luxurious trio, feel free to experiment! You can use semi-sweet chocolate for a richer taste or even flavored chocolate—like orange or mint—for a fun twist. Just remember to choose high-quality chocolate, as it really makes a difference in taste and texture.
