How to Prepare
Start by preheating your oven and greasing a sheet cake pan. In a mixing bowl, whisk together flour, baking powder, and salt. In a separate large bowl, beat the eggs and sugar until pale and fluffy, then add in vegetable oil, milk, and vanilla extract. Slowly fold the dry ingredients into the wet mixture until smooth. Pour the batter into the prepared pan and bake until a toothpick comes out clean.
Once the cake cools, poke small holes across the surface and brush generously with brewed espresso to infuse it with rich coffee flavor. For the frosting, whip heavy cream with powdered sugar until soft peaks form, then gently fold in mascarpone cheese and a splash of vanilla. Spread this creamy mixture evenly over the cooled cake. Finish with a generous dusting of cocoa powder on top before slicing and serving.
Pro Tips
Use freshly brewed espresso for the best depth of flavor. Allow the cake to cool completely before adding the mascarpone frosting to prevent it from melting. For extra richness, chill the cake overnight to let the flavors fully develop. Always whip the cream to soft peaks before folding in mascarpone to achieve a smooth and airy texture.
Perfect Pairings and Toppings
This tiramisu sheet cake pairs wonderfully with a hot cup of espresso or cappuccino to complement the coffee notes in the cake. For gatherings, serve it with a glass of dessert wine or a creamy latte for a more indulgent experience. You can also top the cake with shaved chocolate curls, a sprinkle of cinnamon, or even a drizzle of chocolate sauce for an elegant finish.
