Ingredients

For the cake

2 tablespoons unsalted butter, melted
3½ tablespoons whole milk
¼ teaspoon vanilla extract
2 tablespoons granulated sugar
¼ cup (38g) all-purpose flour
¼ teaspoon baking powder
Pinch kosher salt

For the filling

4 oz (115g) mascarpone cheese
4 oz (115g) cream cheese, softened
¼ cup (50g) granulated sugar
¼ cups (600ml) heavy whipping cream

For the soaker

½ cup (120ml) coffee, at room temperature
2 tablespoons instant coffee
⅓ teaspoon sugar (optional)

Preparation

Make the cake: In a Square dish, combine all cake ingredients and mix until a batter forms, being careful not to over mix. Scrape down the sides, then cover with lid (knob lifted).
Cook in the microwave for 2-3 minutes, or until the cake is bouncy to the touch. To test if the cake is done, gently insert a toothpick or cake tester into the center of the cake and if it comes out clean, the cake is ready.
Make the mascarpone filling: While the cake cools, mix mascarpone, cream cheese, and sugar until smooth. Add cream and mix until fully incorporated. Set aside.
Make the soaker: Stir instant coffee into the cooled coffee and add sugar to taste, if desired.
Assemble the cake: Once the soaker is fully absorbed, top the cake with the mascarpone mixture, spreading the cream evenly with an offset spatula.
Cover with the lid and chill in the refrigerator for at least 3 hours before serving. When ready to serve, dust the top with an even layer of cocoa powder.

Serving suggestions & tips

Salted caramel: Spread a layer of salted caramel sauce on top of the cake before adding the mascarpone filling for a rich, sweet contrast.
Spiked tiramisu: For an adult twist, add a splash of coffee liqueur, Irish cream, or bourbon to the coffee soaker to infuse your tiramisu with a delightful kick.
Chocolate tiramisu: Substitute chocolate milk for coffee to create a kid-friendly version.
Ricotta tiramisu: Use ricotta in place of cream cheese for a lighter filling reminiscent of cannoli cream.

Recipe notes

For a more classic tiramisu, use store-bought ladyfingers instead of making the cake. Simply layer the ladyfingers in the Anyday dish, soak with coffee mixture and top with the mascarpone filling!

All You Need to Know About Making Tiramisu Sheet Cake in the Microwave

What is Tiramisu?

Tiramisu is a classic Italian dessert made with layers of coffee-soaked ladyfingers, creamy mascarpone cheese, and cocoa powder. Our recipe updates the classic by using a homemade, microwave “baked” cake instead of ladyfingers, adding a fresh twist to this beloved treat.

Can I make tiramisu sheet cake in the microwave?

Yes, you can! Using a Square dish, you can easily make a light and tender cake that holds up beautifully under the filling and soaker. Using an Anyday allows you to cook, assemble and serve all in the same dish. Cover the Anyday with the lid and take this dessert to any potluck or party!

Can I use regular coffee instead of instant coffee in the soaker?

Absolutely. You can substitute instant coffee with regular brewed coffee in the soaker. Just adjust the quantity to achieve your preferred strength of coffee flavor, or use espresso for an even bolder taste.

How long should I let the cake cool before adding the filling and soaker?

Allow the cake to cool for approximately 5 minutes before adding the filling and soaker. This brief cooling period helps the cake set properly. After adding the filling and soaker, place the dessert in the fridge to chill and develop its flavors.

Can I substitute mascarpone cheese with another type of cheese?

Yes, you can use sour cream, crème fraîche, or ricotta in place of mascarpone. Keep in mind that these substitutions may slightly alter the flavor and texture.

How far in advance can I make the Tiramisu Sheet Cake before serving?

You can prepare the Tiramisu Sheet Cake 1-2 days in advance. Always make sure the cake is made at least 3 hours before serving to let the flavors meld, then cover the Anyday dish with its lid and refrigerate until ready to serve.
