Olive Garden Tuxedo Cake Copycat Recipe

This Olive Garden tuxedo cake recipe brings home the restaurant’s signature layered chocolate and vanilla dessert without the reservation. It’s a showstopper that comes together with straightforward steps, and it’s the kind of thing you can bake on a weekend and serve all week.

If you’ve had the real thing, you know it’s all about the contrast: dark chocolate cake, white chocolate mousse, and a glossy ganache on top. This version nails that balance.

Why I Love This Recipe

The white chocolate mousse layer stays light and creamy without being cloying, because the ratio of cream to chocolate is kept in check. The chocolate sponge has a tight crumb that holds up to slicing without crumbling.

This is the version I keep coming back to for birthdays and dinner parties. It looks complicated, but every component is one bowl or one saucepan.

Recipe Ingredients

• 2 cups all-purpose flour – Spoon and level it; packing the cup makes the cake dense
• 2 cups granulated sugar – Standard white sugar works best here
• 3/4 cup unsweetened cocoa powder – Dutch-process gives a deeper, less bitter chocolate flavor
• 2 tsp baking soda – Makes the layers rise evenly
• 1 tsp baking powder – Works alongside the baking soda for lift
• 1 tsp fine salt – Balances the sweetness throughout
• 2 large eggs – Room temperature, so they blend smoothly into the batter
• 1 cup buttermilk – Keeps the crumb tender and slightly tangy; see swaps below
• 1 cup strong brewed coffee, cooled – Deepens the chocolate flavor without tasting like coffee
• 1/2 cup vegetable oil – Keeps the cake moist even after refrigerating
• 2 tsp vanilla extract – Split between the cake and mousse layers
• 8 oz good-quality white chocolate, finely chopped – Avoid chips; they have stabilizers that can make the mousse grainy
• 2 1/2 cups heavy cream, divided – 1/2 cup goes into the mousse base, 2 cups are whipped
• 2 tbsp powdered sugar – Stabilizes the whipped cream in the mousse
• 6 oz semi-sweet chocolate, finely chopped – For the ganache topping
• 3/4 cup heavy cream – For the ganache; measured separately from the mousse cream above
• 1 cup fresh raspberries – For garnish; the tartness cuts through the richness

Variations / Substitutions

• No buttermilk – Mix 1 cup whole milk with 1 tbsp white vinegar and let it sit for 5 minutes; the cake bakes up nearly identically.
• Dark chocolate ganache – Swap the semi-sweet chocolate for 70% dark chocolate for a sharper, more bitter finish that contrasts harder with the mousse.
• Coffee-free – Replace the 1 cup brewed coffee with 1 cup hot water; the cake is slightly less deep in flavor but still solidly chocolatey.
• White chocolate swap – If white chocolate is unavailable, a vanilla pastry cream works as the mousse base, though the texture is denser.
• Dairy-free – Full-fat coconut cream can replace the heavy cream in the mousse and ganache; the mousse will be slightly coconut-forward.
• Raspberry garnish – Sliced strawberries or dark cherries work just as well on top and lean into the chocolate pairing the same way.

If you enjoy layered chocolate cakes like this one, the Olive Garden Black Tie Mousse Cake is a close cousin worth making next.

How To Make Tuxedo Cake

Step 1: Bake the Chocolate Layers

Heat your oven to 350°F (175°C). Grease two 9-inch round cake pans and line the bottoms with parchment. In a large bowl, whisk together the 2 cups flour, 2 cups granulated sugar, 3/4 cup cocoa powder, 2 tsp baking soda, 1 tsp baking powder, and 1 tsp salt. In a separate bowl, whisk the 2 eggs, 1 cup buttermilk, 1 cup cooled coffee, 1/2 cup vegetable oil, and 1 tsp vanilla extract. Pour the wet ingredients into the dry and stir until just combined, about 30 seconds of stirring once the dry flour disappears.

The batter will be thinner than most cake batters, almost pourable. That’s fine. Divide it evenly between the two pans and bake for 30 to 35 minutes, until a toothpick inserted in the center comes out with just a few moist crumbs.

Let the layers cool in the pans for 10 minutes, then turn them out onto a wire rack and cool completely before assembling. A warm cake will melt the mousse layer, so give it at least an hour.

Step 2: Melt the White Chocolate Base

Pour the 1/2 cup heavy cream into a small saucepan over medium-low heat. Warm it until you see steam rising and small bubbles forming at the edges, about 3 to 4 minutes. Do not let it boil. Take it off the heat and add the 8 oz finely chopped white chocolate all at once. Let it sit for 2 minutes, then stir slowly from the center outward until completely smooth.

Stir in the remaining 1 tsp vanilla extract. Transfer the mixture to a wide bowl and let it cool at room temperature for 20 minutes, then refrigerate for at least 30 minutes until it’s thick and cool to the touch but not set solid.

If the white chocolate seizes or looks lumpy, the cream was likely too hot. Press it through a fine mesh strainer while it’s still warm and it will usually smooth out.

Step 3: Whip the Mousse

Pour the 2 cups heavy cream and 2 tbsp powdered sugar into a chilled bowl. Beat on medium-high speed until stiff peaks form, about 3 to 4 minutes with a hand mixer. Take the cooled white chocolate mixture out of the fridge and fold about one-third of the whipped cream into it using a spatula, pressing gently to lighten it. Fold in the remaining whipped cream in 2 additions until just combined, with no white streaks.

The mousse should feel airy but hold its shape when you lift the spatula. Work quickly once the whipped cream goes in, and keep the bowl in the fridge until you’re ready to build the cake.

Step 4: Assemble the Layers

Place one cooled cake layer on a serving plate or cake board. Spread half the white chocolate mousse over the top in an even layer, going nearly to the edges. Set the second cake layer on top and press down gently so it sits flat. Spread the remaining mousse over the top and smooth it with an offset spatula, leaving the sides of the cake exposed. Refrigerate the assembled cake for at least 30 minutes so the mousse firms up before the ganache goes on.

Getting the mousse layer level matters here because the ganache will flow over whatever surface it finds. Take an extra minute to flatten it.

Step 5: Pour the Ganache

Place the 6 oz finely chopped semi-sweet chocolate in a heatproof bowl. Heat the 3/4 cup heavy cream in a small saucepan over medium heat until it just begins to simmer, about 3 minutes. Pour it over the chocolate, wait 2 minutes, then stir slowly from the center out until the ganache is completely glossy and smooth. Let it cool at room temperature for 8 to 10 minutes until it’s thick enough to coat the back of a spoon but still pours in a slow, steady stream.

Pour the ganache over the center of the chilled cake and nudge it toward the edges with an offset spatula, letting it drip slightly over the sides for a natural finish. If the ganache sets too fast, warm it for 10 seconds in the microwave and stir before continuing.

Step 6: Garnish and Serve

Scatter the 1 cup fresh raspberries over the top of the ganache while it’s still slightly tacky, pressing each one down gently so they stay put. Slice with a sharp knife run under hot water and wiped dry between cuts. Serve each piece showing the full cross-section of dark cake, white mousse, and glossy ganache.

Recipe Tips

• Use room-temperature eggs and buttermilk. Cold dairy straight from the fridge can cause the batter to look curdled. It won’t hurt the final cake, but it does mix more evenly when everything is at the same temperature.
• Chill your bowl before whipping cream. A cold metal bowl keeps the cream from warming up mid-whip, which is the most common reason mousse ends up runny.
• Chop chocolate finely. Smaller pieces melt faster and more evenly in the hot cream. Coarse chunks can leave you with a lumpy ganache or mousse base even after stirring.
• Level the cake layers before assembling. If either layer has a dome in the center, use a serrated knife to trim it flat. A level surface means the mousse layer won’t slide.

Cook times vary slightly by pan material; here’s a quick guide.

Pan material	Pan size	Approximate bake time
Light aluminum	9-inch round	30 to 33 minutes
Dark nonstick	9-inch round	28 to 30 minutes
Glass	9-inch round	33 to 36 minutes

How To Store

• Refrigerate – Cover the cake loosely with plastic wrap or store it in a cake dome. It keeps well for up to 4 days. The mousse firms up overnight, which actually makes slicing cleaner.
• Serve Cold – This cake is best served cold or at cool room temperature. The mousse layer holds its shape better when it hasn’t been sitting out for more than 30 minutes.

What To Serve With Tuxedo Cake

A small scoop of vanilla bean ice cream alongside a slice works well because the cold, plain dairy contrasts the richness of the ganache without fighting the white chocolate. A shot of espresso or a strong americano is a natural match since the bitterness cuts right through the sweetness of the mousse. If you’re serving it at a dinner party, a glass of dry sparkling wine does something similar, the acidity keeps the richness of the cake from becoming heavy.

Frequently Asked Questions

Can I make this cake a day ahead?

Yes. The assembled cake actually slices more cleanly after overnight refrigeration because the mousse sets firmer. Add the raspberries the day you serve it so they stay fresh.

Can I use a box cake mix for the chocolate layers?

You can. Use a dark chocolate box mix prepared according to its directions and proceed from the mousse step onward. The crumb will be slightly springier, but the overall result holds up.

How do I prevent the ganache from sliding off the mousse layer?

Make sure the assembled cake is well-chilled (at least 30 minutes in the fridge) before you pour the ganache, and let the ganache cool to a spoon-coating thickness before it goes on. A warm ganache on a soft mousse will always migrate.

Can I freeze slices?

Yes. Wrap individual slices tightly in plastic wrap, then foil, and freeze for up to 1 month. Thaw in the fridge overnight. The mousse texture softens slightly but is still good.
