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. Pour the soaker over the cooked caked and set aside.
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!
