How to Make Tuxedo Cake – Triple Chocolate Mousse Cake
Step 1: Make the Chocolate Cake
Start by preheating your oven to 350°F (180°C). Greasing and lining two 8-inch round cake pans will help ensure your cakes come out smoothly without sticking. In a large mixing bowl, sift together the flour, sugar, cocoa powder, baking powder, baking soda, and salt. Whisk these dry ingredients well; this helps aerate them and ensures an even distribution of flavors.
In another bowl, combine the eggs, milk, sour cream, oil, and vanilla until smooth. Mixing wet ingredients separately allows them to blend thoroughly before combining them with dry ingredients. Add this mixture into your dry ingredients and stir until everything is fully combined.
Next comes the secret ingredient—dissolve espresso powder in hot water and add it to your batter. This step intensifies the chocolate flavor! Divide your batter between the prepared pans and bake for about 35 minutes. Check doneness by inserting a toothpick; it should come out clean!
Step 2: Make the Chocolate Mousses
While your cakes cool down completely in their pans, let’s whip up those fabulous mousses! Start by placing chopped dark and white chocolates into separate bowls. Then whisk together egg yolks with sugar and cornstarch until pale; this will be the base of your mousse.
Heat one portion of heavy cream with vanilla until steaming—this helps melt your chocolates later on! Slowly drizzle this hot mixture into your egg yolk mix while whisking constantly; it’s important not to scramble those eggs! Pour everything back into the saucepan and cook over medium heat until thickened—it’ll take about 1-2 minutes of constant whisking.
Now pour half of that custard over each bowl of chocolate and stir until smooth. Fold whipped cream into both mixtures carefully; we want them light and airy!
Step 3: Assemble the Cake
It’s time to layer everything together! Place one layer of cake at the bottom of a cake ring on a serving plate or board. Spread an even layer of dark chocolate mousse over it first—this is where things start getting exciting! Carefully spoon white chocolate mousse on top next.
Chill these layers in the fridge for about 30 minutes so they can set slightly before adding on that second cake layer. Once added on top, chill again for at least 4 hours—this ensures everything binds beautifully together!
Step 4: Make the Chocolate Ganache
Let’s finish off our masterpiece with ganache! Heat more cream until steaming again but not boiling this time. Pour it over chopped milk chocolate; let it sit for one minute before stirring until smooth. Let it cool slightly until thickened before spreading over your chilled cake.
Step 5: Decorate
Feel free to get creative here! Garnish with chocolate shavings or sprinkles—whatever makes you smile! Refrigerate until you’re ready to serve.
And there you have it—a stunning Tuxedo Cake – Triple Chocolate Mousse Cake that’s sure to impress! Enjoy every decadent slice with friends and family!
Pro Tips for Making Tuxedo Cake – Triple Chocolate Mousse Cake
Creating a stunning Tuxedo Cake can seem daunting, but with these simple tips, you’ll be on your way to baking success!
-
Use room temperature ingredients: This ensures better mixing and helps your cake rise evenly, resulting in a moist and fluffy texture.
-
Measure accurately: Baking is a science! Use a kitchen scale for the best results, especially for ingredients like flour and sugar, to ensure consistency in your cake.
-
Be patient with chilling: Allowing the mousse layers to set properly in the fridge will give your cake a beautifully structured look when sliced and enhance the flavors.
-
Don’t rush the ganache: Give the ganache time to cool and thicken slightly before pouring it over the cake. This will help it maintain a glossy finish without dripping off too much.
-
Experiment with flavors: While this recipe features rich chocolate flavors, feel free to add a hint of orange zest or espresso powder to the mousse mixtures for an extra layer of depth.
