3 shots espresso
White Chocolate Mousse
8 ounces white chocolate, chopped

Instructions
Step 1: Prepare the Cake Pans
Preheat the oven to 350°F.
Lightly grease three 6-inch round cake pans.
Step 2: Brown the Butter
Add the butter to a saucepan over medium heat.
Cook until the butter begins to turn golden brown and develops a warm, nutty aroma.
Remove from the heat.
Step 3: Add the Chocolate & Espresso
Add the semi-sweet chocolate to the warm brown butter and stir until completely melted and smooth.
Pour in the espresso and stir to combine.
Set aside briefly.
Step 4: Make the Chocolate Cake Batter
In a large mixing bowl, combine the flour, granulated sugar, cocoa powder, baking powder, baking soda, and salt.
Add the eggs, milk, and vanilla and begin mixing.
Pour in the brown butter, chocolate, and espresso mixture.
Mix until everything is fully incorporated and the batter is smooth.
Step 5: Bake the Cake
Divide the batter evenly between the three prepared 6-inch cake pans.
Bake for approximately 45–55 minutes, or until a toothpick inserted into the center comes out clean or with a few moist crumbs.
Allow the cakes to cool in their pans briefly before transferring them to cooling racks.
Cool completely before assembling.
Step 6: Make the White Chocolate Mousse
Melt the white chocolate in the microwave in approximately 15-second intervals, stirring between each interval until smooth.
Allow it to cool slightly.
In a separate bowl, whip the heavy cream until it begins forming soft peaks.
Add the powdered sugar and vanilla and continue whipping until the mixture holds its shape.
Gently fold the cooled white chocolate into the whipped cream, taking care not to deflate the mixture.
Cover and refrigerate for at least 2 hours.
Step 7: Make the Dark Chocolate Mousse
Repeat the same process using the dark chocolate.
Melt the chocolate until smooth and allow it to cool slightly.
Whip the heavy cream until soft peaks begin to form, then add powdered sugar and vanilla.
Gently fold in the cooled dark chocolate.
Cover and refrigerate for at least 2 hours.
Step 8: Make the Milk Chocolate Ganache
Heat the heavy cream until hot and just beginning to bubble.
Place the milk chocolate in a heat-safe bowl and pour the hot cream over it.
Add the maple syrup.
Let everything sit undisturbed for approximately 1 minute, then slowly stir until the chocolate and cream are completely combined and smooth.
If needed, heat in approximately 10-second intervals and stir again until smooth.
Press plastic wrap directly against the surface of the ganache and allow it to cool for approximately 3 hours, or until it reaches a thick, spreadable consistency.
Step 9: Level the Cakes
Once the chocolate cakes have completely cooled, use a serrated knife to carefully level the tops if needed.
Step 10: Assemble the Tuxedo Cake
Place the first chocolate cake layer onto your cake stand.
Spread one of the chocolate mousses evenly over the cake.
Add the second cake layer and spread the contrasting mousse over the top.
Finish with the final chocolate cake layer.
Step 11: Crumb Coat
Spread a thin layer of chocolate ganache over the entire cake.
This crumb coat will catch any loose crumbs and create a smooth base for the final layer.
Chill until the crumb coat has set.
Step 12: Finish the Cake
Cover the cake with the remaining milk chocolate ganache.
Smooth the exterior or create a more textured finish depending on the look you prefer.
Decorate as desired, slice, and enjoy!
Amanda's Quick Tips
Don't rush the brown butter. Wait for that nutty aroma before removing it from the heat.
Melt the chocolate directly into the warm brown butter.
Espresso enhances the chocolate flavor, so I wouldn't skip it unless you need to.
Let melted chocolate cool slightly before folding it into whipped cream.
Fold the mousse gently so you don't lose its light texture.
Chill both mousses for at least two hours.
Make sure the cakes are completely cool before assembling.
Level your cake layers for the cleanest finished slices.
Give the ganache enough time to cool and thicken before frosting.
A crumb coat makes the final ganache layer much easier to apply.
