Ingredients

(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)

For the Vanilla Cake:
2 1/2 cups all-purpose flour
2 1/2 teaspoons baking powder
1/2 teaspoon salt
1 cup unsalted butter, softened
2 cups granulated sugar
4 large eggs
1 teaspoon vanilla extract
1 cup whole milk

For the Chocolate Ganache Filling:
8 oz semisweet chocolate, chopped
1 cup heavy cream

For the Tiramisu Buttercream:
1/2 cup unsalted butter, softened
8 oz mascarpone cheese
2 cups powdered sugar
1 tablespoon instant espresso powder
1 tablespoon warm water
1 teaspoon vanilla extract
Cocoa powder for dusting

Directions

Preheat the oven to 350°F (175°C). Grease and flour two 9-inch round cake pans.

In a medium bowl, whisk together the flour, baking powder, and salt. Set aside.

In a large bowl, cream the softened butter and sugar together until light and fluffy. Add the eggs one at a time, mixing well after each addition. Stir in the vanilla extract.

Alternately add the flour mixture and milk to the butter mixture, beginning and ending with the flour mixture. Mix until just combined. Divide the batter evenly between the prepared pans.

Bake for 25 to 30 minutes, or until a toothpick inserted into the center comes out clean. Allow the cakes to cool completely on wire racks before assembling.

To make the ganache, heat the heavy cream in a saucepan until it just begins to simmer. Pour the hot cream over the chopped chocolate and let it sit for 2 minutes. Stir until smooth and glossy. Let the ganache cool until thickened but still spreadable.

For the tiramisu buttercream, dissolve the instant espresso powder in warm water. In a large bowl, beat the butter and mascarpone together until smooth and creamy. Gradually add the powdered sugar, followed by the espresso mixture and vanilla extract. Beat until light and fluffy.

To assemble, place one cake layer on a serving plate. Spread an even layer of ganache over the top. Add the second cake layer and frost the entire cake with the tiramisu buttercream. Finish with a light dusting of cocoa powder before serving.

Variations

For a stronger coffee flavor, brush the cake layers lightly with cooled espresso before adding the ganache.

You can swap semisweet chocolate for dark chocolate in the ganache for a deeper, more intense flavor.

Add a splash of coffee liqueur to the buttercream for an extra tiramisu-inspired twist.

Top the cake with chocolate shavings or chocolate-covered espresso beans for added texture and visual appeal.

For a lighter option, use a stabilized whipped cream frosting instead of buttercream while keeping the mascarpone for flavor.

Storage/Reheating

Store the cake in an airtight container in the refrigerator for up to 4 days due to the mascarpone in the frosting. Allow the cake to sit at room temperature for about 30 minutes before serving to soften the buttercream and enhance the flavors.

If you need to freeze it, wrap the unfrosted cake layers tightly in plastic wrap and freeze for up to 2 months. Thaw overnight in the refrigerator before assembling and frosting.

FAQs

Can I make this cake ahead of time?

Yes, you can bake the cake layers a day in advance. Store them tightly wrapped at room temperature and assemble the cake the next day.

Can I use cake flour instead of all-purpose flour?

Yes, cake flour will give the cake an even softer crumb. Substitute it in equal amounts for a lighter texture.

What if I don’t have mascarpone cheese?

You can substitute with full-fat cream cheese, though the flavor will be slightly tangier and less traditional.

How do I prevent the ganache from being too runny?

Allow the ganache to cool and thicken before spreading it on the cake. If it’s too warm, it will not set properly.

Can I turn this into cupcakes?

Yes, divide the batter into cupcake liners and bake for 18 to 22 minutes. Fill and frost as directed.

Does the cake need to be refrigerated?

Yes, because of the mascarpone in the buttercream, refrigeration is recommended.

Can I make the buttercream less sweet?

You can reduce the powdered sugar slightly and add a pinch of salt to balance the sweetness.

How do I get clean cake slices?

Chill the cake for about 20 minutes before slicing and wipe the knife clean between cuts.

Can I use milk chocolate instead of semisweet?

Yes, but the filling will be sweeter and less intense in flavor.

What makes this cake taste like tiramisu?

The combination of mascarpone, espresso, vanilla, and cocoa powder recreates the classic tiramisu flavor profile in cake form.
