This cake features all-purpose flour, baking powder, butter, eggs, and buttermilk for the base. The coffee soak includes strong brewed coffee, marsala wine (or rum), and sugar. The mascarpone frosting combines mascarpone cheese, powdered sugar, heavy cream, and vanilla, finished with cocoa powder.
Learn how to cook Tiramisu Sheet Cake by first baking a vanilla cake, then soaking it with coffee and marsala mixture. Prepare a mascarpone frosting by folding whipped cream into sweetened mascarpone cheese, then spread over the soaked cake. After chilling for at least 4 hours, dust with cocoa powder before serving for that authentic tiramisu flavour.
Yes, you can easily make an alcohol-free version by omitting the marsala wine or rum and replacing it with additional coffee or coffee extract. For a family-friendly option, use 2 tablespoons of vanilla extract mixed with the coffee soak instead to maintain depth of flavour.
Mascarpone frosting will keep well in the refrigerator for up to 5 days when properly stored in an airtight container. The frosting may firm up significantly when chilled, so allow it to sit at room temperature for 15-20 minutes before using if you're making it in advance.
For the best coffee flavour, use freshly brewed espresso or very strong coffee rather than instant coffee. Allow it to cool completely before adding to your soak mixture. For an even more pronounced coffee taste, add 1-2 teaspoons of coffee extract or a tablespoon of coffee liqueur.
