Step‑by‑Step Instructions for Tuxedo Cake
Step 1: Preheat the Oven
Start by preheating your oven to 350°F (175°C). While the oven heats, prepare your two 8-inch cake pans by greasing them well and dusting with flour. This ensures the Tuxedo Cake comes out smoothly after baking. Set the prepared pans aside while you move on to the next step.
Step 2: Mix the Dry Ingredients
In a large mixing bowl, sift together the all-purpose flour, granulated sugar, unsweetened cocoa powder, baking powder, baking soda, and salt. Use a whisk to combine these dry ingredients evenly; this helps to aerate the mixture. Once well mixed, you’re ready to introduce the wet ingredients, bringing together the elements that make this Tuxedo Cake so decadent.
Step 3: Combine Wet Ingredients
In a separate bowl, mix together the buttermilk, vegetable oil, eggs, vanilla extract, and sour cream. These ingredients add moisture and flavor to your Tuxedo Cake. Gradually add this wet mixture to your dry ingredients, mixing until you achieve a smooth batter. The batter should be rich and velvety, ready for the next important addition.
Step 4: Incorporate Boiling Water
Carefully stir in the boiling water to the cake batter, which will give the mixture a thinner consistency. This step ensures that your Tuxedo Cake bakes up moist and tender. Mix until well combined and pour the batter evenly into the prepared cake pans.
Step 5: Bake the Cakes
Place the filled pans in the preheated oven and bake for 35-40 minutes, or until a toothpick inserted in the center comes out clean. As they bake, the wonderful aroma of chocolate will fill your kitchen. Once done, remove the pans from the oven and let the cakes cool in the pans for about 10 minutes before transferring them onto a wire rack to cool completely.
Step 6: Prepare the Dark Chocolate Mousse
While the cakes are cooling, start on the dark chocolate mousse. In a saucepan, melt together the semi-sweet chocolate and unsalted butter over low heat, stirring continuously. Once melted, let it cool slightly. In a separate bowl, whip the heavy cream until soft peaks form, then gently fold in the cooled chocolate mixture. Lastly, incorporate the meringued egg whites to achieve lightness in the mousse.
Step 7: Create the White Chocolate Mousse
Next, prepare the white chocolate mousse. Melt the white chocolate over low heat, stirring until smooth. In another bowl, whip the cream and egg whites separately until they each hold soft peaks. Carefully fold the whipped cream into the melted white chocolate, followed by the egg whites, creating a fluffy texture that will complement the Tuxedo Cake beautifully.
Step 8: Make the Ganache
For the ganache, heat the heavy cream in a small saucepan until it’s just about to boil. Pour the hot cream over chopped semi-sweet chocolate in a bowl and let it sit for a minute to melt. Stir until smooth and glossy, allowing it to cool slightly to a spreadable consistency while you get ready to assemble your cake.
Step 9: Assemble the Tuxedo Cake
Once the cakes are completely cooled, carefully level each layer with a serrated knife. Place one cake layer on a serving plate, and spread a layer of buttercream followed by the dark chocolate mousse. Top with a second cake layer, then spread the white chocolate mousse. Repeat the process until all layers are assembled, finishing with the final cake layer at the top.
Step 10: Finish with Ganache and Decoration
Pour the cooled ganache over the top of the assembled Tuxedo Cake, allowing it to drip down the sides for a beautiful finish. For an elegant touch, decorate the top with chocolate curls or additional ganache, creating a stunning presentation. Refrigerate the cake until set; this will enhance the flavors and textures before serving.

Very good question! Store your Tuxedo Cake in the refrigerator, tightly covered with plastic wrap or an airtight container, where it can last for up to 5 days. This helps maintain its freshness and keeps the mousse layers intact.

How do I prevent my mousse from becoming grainy?
To avoid a grainy texture, don’t over-whip your cream. Whip until soft peaks form but stop before it becomes stiff. Keep an eye on the temperature of your melted chocolate as well; it should cool slightly before being combined with the whipped cream. This will help create a smooth and creamy consistency for your Tuxedo Cake.

If your cake layers come out domed, no worries! Use a serrated knife to level the tops gently. This ensures that your layers fit well together when assembling the Tuxedo Cake, resulting in a neat and professional-looking dessert.
Are there any allergen considerations for Tuxedo Cake?
Definitely! If you’re catering to specific dietary needs, you can consider using gluten-free flour if needed.
