Step-by-step baking and assembly guide
Make the cake layers
- Set oven to 350°F (175°C). Grease and flour three 8-inch round pans or line with parchment.
- Whisk together sugar, flour, cocoa, baking powder, baking soda and salt until uniform.
- Beat in eggs, milk, oil and vanilla on medium speed until smooth, about 2 minutes.
- Carefully pour in hot brewed coffee and stir until batter is fluid and even.
- Divide batter between the three pans and bake 30–35 minutes. A toothpick should come out clean.
- Let pans cool 10 minutes, then transfer cakes to a wire rack to cool completely.
Prepare the dual chocolate fillings
- Gently melt the semisweet chocolate and allow it to cool to room temperature.
- Melt the white chocolate separately and set aside to cool.
- Whip the heavy cream with powdered sugar until soft peaks form.
- Beat in the cream cheese and vanilla until the mixture is smooth and even.
- Split the cream mixture into two portions: one larger and one smaller.
- Fold melted semisweet chocolate and cocoa into the larger portion for the dark filling.
- Fold melted white chocolate into the smaller portion for the light filling.
Assemble the cake and create the swirled finish
- Place one cake layer on a serving plate. Spread a layer of the white chocolate filling.
- Add the second cake layer and spread the dark chocolate filling on top of it.
- Top with the third layer. Use the dark filling to frost the sides and top of the assembled cake.
- For the glossy glaze, melt 4 oz semisweet chocolate with 1 tablespoon oil until smooth.
- Pour the glossy chocolate over the frosted cake, letting it drip slightly down the sides.
- Melt 1 oz white chocolate with 1 teaspoon oil and drizzle thin lines across the top.
- Drag a toothpick through the lines to produce a decorative swirl pattern.
- Chill the finished cake in the refrigerator until the fillings and glaze firm up.
Practical tips for a successful tuxedo cake
- Use hot coffee: it enhances the chocolate flavor and thins the batter for even layers.
- Allow melted chocolate to cool to room temperature before folding into whipped cream.
- If a layer breaks, press the pieces together with a little filling; the cake will still taste great.
- Chill between steps to make spreading and glazing easier.
- For cleaner slices, refrigerate the cake and run a warm knife through each cut.
Common mistakes and quick fixes
- Too-soggy layers: reduce coffee slightly or bake an extra 2–3 minutes.
- Fillings too loose: whip a touch longer or add a tablespoon more cooled melted chocolate.
- Glaze too thick: stir in a small amount of warm cream or more oil, one teaspoon at a time.
- White chocolate grainy: melt gently over low heat or in short bursts in a microwave, stirring often.
