Understanding Tiramisu Cake
Tiramisu, an Italian dessert that translates to "pick me up" or "cheer me up," is a heavenly mix of coffee-soaked ladyfingers and mascarpone cheese, dusted with cocoa powder. Joanna Gaines' Tiramisu Cake takes this classic dessert and transforms it into a show-stopping layered cake, perfect for satisfying your sweet tooth while impressing your guests.
Gathering Your Ingredients
Before you begin, ensure you have all the necessary ingredients to create this masterpiece. Here's a list of what you'll need:

- 2 cups all-purpose flour
- 2 cups granulated sugar, divided
- 3/4 cup unsweetened cocoa powder, divided
- 2 teaspoons baking powder
- 1 1/2 teaspoons baking soda
- 1 teaspoon salt
- 1 cup buttermilk
- 1/2 cup vegetable oil
- 2 large eggs
- 2 teaspoons vanilla extract
- 1 cup strong brewed coffee, cooled
- 1 cup mascarpone cheese, at room temperature
- 1 cup heavy whipping cream
- 1 teaspoon rum extract (optional)
Baking the Cake Layers
Preheat your oven to 350°F (175°C) and grease and flour two 9-inch round cake pans. In a large bowl, whisk together the flour, 1 1/2 cups of sugar, 1/2 cup of cocoa powder, baking powder, baking soda, and salt. Create a well in the center and add the buttermilk, vegetable oil, eggs, and vanilla extract. Mix until well combined and smooth.
Divide the batter evenly between the prepared pans and bake for 25-30 minutes, or until a toothpick inserted into the center comes out clean. Allow the cakes to cool in the pans for 10 minutes before transferring them to a wire rack to cool completely.
Assembling the Tiramisu Cake
While the cakes are cooling, prepare the coffee syrup by combining the remaining 1/2 cup of sugar and 1/4 cup of cocoa powder with the cooled coffee in a small saucepan. Heat over medium heat until the sugar dissolves, then remove from heat and let it cool.

In a separate bowl, beat the mascarpone cheese until smooth, then gradually add the remaining 1/2 cup of sugar and beat until light and fluffy. Add the heavy whipping cream and rum extract (if using), and beat until stiff peaks form.
Once the cakes have cooled completely, use a fork or a skewer to poke holes in the surface of one of the cakes. Brush the coffee syrup over the cake, allowing it to soak in. Spread half of the mascarpone mixture over the cake, then place the second cake on top. Poke holes in the second cake and brush with the remaining syrup. Spread the remaining mascarpone mixture over the top and sides of the cake.
Dust the entire cake with the remaining 1/4 cup of cocoa powder, using a sifter or a fine-mesh strainer to ensure an even coating. Chill the cake for at least 2 hours before serving to allow the flavors to meld together.
Serving and Storing Joanna Gaines' Tiramisu Cake
When ready to serve, slice the cake into generous portions and enjoy the perfect balance of coffee, cream, and chocolate in every bite. Store any leftovers in an airtight container in the refrigerator for up to 5 days.
