Learn how to make super easy Tiramisu Cake Recipe. A homemade vanilla cake is soaked with espresso and finished with an espresso mascarpone whipped cream frosting. Watch the Tiramisu Cake Video for step by step instructions!



Vanilla Cake

  • 260g all-purpose flour
  • 2 tsp baking powder
  • 1/2 tsp kosher salt
  • 220g buttermilk, at room temperature
  • 1 tsp vanilla bean paste
  • 150g unsalted butter, at room temperature
  • 160g granulated sugar
  • 2 large eggs, at room temperature

Coffee Soak 

  • 50g strong coffee, cold.

Espresso Mascarpone Frosting

  • 230g mascarpone, cold
  • 1 1/2 tsp espresso powder or fine instant coffee
  • 110g powdered sugar, sifted
  • 1/4 tsp vanilla bean paste
  • pinch of salt
  • 240g heavy cream, cold from the fridge

Cocoa powder to dust



  1. Preheat the oven to 350°f / 180°c. Grease and line a 9"x13" (20cm x30cm) pan or quarter sheet pan with parchment paper. 
  2. In a medium bowl, combine the flour, baking powder, and salt.
  3. In a small bowl, combine the buttermilk and vanilla.
  4. In a medium bowl using an electric mixer cream together the butter and sugar until light and fluffy, scraping down the sides as needed. 
  5. Add the eggs and mix until incorporated. Scrape down the sides of the bowl using a spatula. 
  6. With the mixer on low, alternately add the wet and dry ingredients. Add a third of the dry ingredients, followed by half the wet ingredients, then another third of the dry ingredients, followed by the second half of the wet ingredients. Finally, add the remaining third of the dry ingredients. Mix until just incorporated, scraping down the sides as needed. 
  7. Transfer the mixture to the prepared pan and smooth down. Tap the pan on the counter a few times to ensure the mixture is settled. 
  8. Bake the cake for 25 to 30 minutes, until the top is golden brown, springs back when lightly pressed, and a skewer inserted into the middle of the cake comes out clean.
  9. Cool the cake in the pan for 10-15 minutes, then transfer the cake to the serving plate. Brush liberally with the coffee and leave to cool completely. 


  1. Place the mascarpone and espresso powder into a medium bowl. Whip with an electric hand mixer on high, until the mascarpone is smooth and the coffee is incorporated. 
  2. Add the powdered sugar, salt, and vanilla, and mix to combine. 
  3. With the mixer still going, stream in the heavy cream until it is all added, then continue to whip. The cream will incorporate and the frosting will seem quite thin - keep mixing until it has the consistency of thick whipped cream. Be careful not to over whip. It will come together quickly. 
  4. Transfer the frosting to a piping bag lined with a french star tip. Pipe blobs all over the surface of the snack cake. Alternatively you can smooth it on with an offset spatula. 
  5. Dust the top of the cake with cocoa powder. Store in the fridge until you serve. 
  6. Store leftovers in an airtight container in the fridge.
