How to Make a Tuxedo Cake (The Ultimate Recipe)

Follow these steps carefully to assemble your stunning Tuxedo Cake. Organization is key, so read through everything before you begin. A great dessert starts with great preparation, like in our popular Chocolate Chip Cookie Pie recipe.

Step 1: Bake the Chocolate Cake Layers

1. Preheat your oven to 350°F (175°C). Grease and flour two 8-inch round cake pans and line the bottoms with parchment paper.
2. In a large bowl, whisk together the flour, sugar, cocoa powder, baking soda, baking powder, and salt.
3. In a separate bowl, combine the eggs, buttermilk, oil, and vanilla extract.
4. Pour the wet ingredients into the dry ingredients and mix on medium speed until just combined. Carefully pour in the hot coffee and mix on low until the batter is smooth. It will be thin.
5. Divide the batter evenly between the prepared pans. Bake for 30-35 minutes, or until a wooden skewer inserted into the center comes out clean.
6. Let the cakes cool in the pans for 15 minutes before inverting them onto a wire rack to cool completely.

Step 2: Prepare the Chocolate Mousse

1. Melt the semi-sweet chocolate in a double boiler or in the microwave in 30-second intervals. Let it cool slightly.
2. In a small bowl, sprinkle gelatin over 2 tablespoons of cold water and let it bloom for 5 minutes. Gently heat it in the microwave for 5-10 seconds to dissolve.
3. Whip 1 ½ cups of heavy cream to soft peaks. Gently fold the slightly cooled melted chocolate and dissolved gelatin into the whipped cream until no streaks remain.

Step 3: Whip Up the White Chocolate Mousse

1. Follow the same process as the chocolate mousse, using the white chocolate and the remaining heavy cream and gelatin. Be careful not to overheat the white chocolate as it can seize easily.

Step 4: Assemble the Layers

1. Once the cake layers are completely cool, level them with a serrated knife if needed. Place one cake layer in the bottom of a springform pan or a cake ring.
2. Spread the chocolate mousse evenly over the first cake layer.
3. Top with the second cake layer, pressing down gently.
4. Spread the white chocolate mousse evenly over the top.
5. Cover and refrigerate the cake for at least 6-8 hours, or preferably overnight, to allow the mousse layers to set completely.

Step 5: Create the Chocolate Ganache

1. Place the chopped dark chocolate in a heatproof bowl.
2. Heat the heavy cream in a small saucepan until it just begins to simmer. Pour the hot cream over the chocolate and let it sit for 5 minutes without stirring.
3. Whisk the mixture gently until it’s smooth and glossy. Let the ganache cool for 15-20 minutes, until it’s thick enough to pour but still fluid.

Step 6: Decorate Your Masterpiece

1. Remove the cake from the springform pan or cake ring and place it on a wire rack with a baking sheet underneath to catch drips.
2. Pour the ganache over the top of the cake, allowing it to drip down the sides. Use an offset spatula to gently smooth the top and guide the ganache if needed.
3. Decorate with chocolate shavings, curls, or fresh berries, if desired. For a fun twist, consider topping it with treats like from our Double Chocolate Chip Cookies recipe.
4. Refrigerate the cake for at least 1 hour for the ganache to set before slicing and serving.

Pro Tips for a Flawless Tuxedo Cake

• Use Room Temperature Ingredients: For the cake batter, ensure your eggs and buttermilk are at room temperature for a smoother, more uniform batter.
• Don’t Overmix: Overmixing the cake batter can develop gluten and result in a tough cake. Mix until just combined.
• Cool Completely: The cake layers must be 100% cool before you add the mousse, otherwise, the mousse will melt and you won’t get clean layers.
• Patience is Key: Allowing the assembled cake to set overnight is crucial for the mousse to firm up, ensuring clean, beautiful slices. Just like with a good no-bake pie, setting time is everything.

Storage and Make-Ahead Instructions

This Tuxedo Cake Recipe is perfect for making ahead. The assembled cake needs to be stored in the refrigerator and is best enjoyed within 3-4 days. You can also freeze the entire cake or individual slices for up to a month. To do so, wrap it tightly in plastic wrap and then in aluminum foil. Thaw in the refrigerator overnight before serving.
