Makes 24 cupcakes For the cupcakes
90g unsalted butter, at room temperature
1 1/3 cups granulated sugar
1 1/2 cups all-purpose flour
1/4 teaspoon salt
1 tablespoon baking powder
2 large eggs, at room temperature
a “scant” 1 cup whole milk
1/2 teaspoon vanilla extract
For the Coffee Soaking Syrup:
1 cup coffee, strong
5 tablespoons coffee liqueur
3 tablespoons granulated sugar
For the Mascarpone Frosting:
300g mascarpone cheese
3 1/2 tablespoons coffee liqueur
1 cup double cream
¼ cup icing sugar
espresso powder, for dusting
cocoa powder, for dusting
For the Tiramisu Cupcakes: Preheat the oven to 190C/fan oven 170C, and line a muffin tin with muffin cases. Using a handheld electric whisk or a freestanding electric mixer with a paddle attachment, beat butter, sugar, flour, salt, and baking powder on low speed until the ingredients are well incorporated and have the texture of fine breadcrumbs.
Break eggs into a measuring cup, then add whole milk and vanilla and whisk together by hand.
With the mixer running on a low speed, slowly pour three-quarters of the wet ingredients into the flour and butter mixture. Once everything has been mixed together, scrape down the sides of the bowl to pick up an ingredients that were missed, then add the rest of the milk mixture and continue mixing the batter until it is smooth and even.
Divide the batter between the paper cases, filling each case with 2 tablespoons of batter (or, filling each up to two-thirds full).
Bake for 18-20 minutes in the preheated oven until well risen and the tops bounce back when touched. Leave to cool slightly before removing them from the tin, then place on a wire rack to cool completely while you make the coffee soaking syrup.
For the Coffee Soaking Syrup:
Pour coffee and coffee liquer into a saucepan and whisk in 3 sugar.
Bring to a boil, allowing the liquid to reduce by about half the pot, then remove from heat and set aside to cool.
For the Mascarpone Cream Frosting:
Using a handheld electric whisk, beat together mascarpone cheese and coffee liquer until smooth.
Pour cream in a separate bowl, icing sugar and using a handheld electric whisk to whip together until the mixture forms soft peaks.
Fold the whipped cream into the mascarpone mixture, making sure the mascarpone and the cream is fully incorporated.
Putting It All Together:
When the cupcakes have cooled, use your corer or a knife to cut out a piece of cake — about 1 inch wide and 1.5 inches deep — from each cupcake. Set aside.
Pour approximately 1 teaspoonful of the Coffee Soaking Syrup over each cut-out piece of the sponge, as well as another teaspoon into the hollow of each cupcake.
Fill each hollow to about halfway with the Mascarpone Cream Frosting, then place the cut-out pieces of the cupcake back on top of the hole, covering the filling and, if necessary, trimming the cupcakes pieces to fit.
Lastly, top the cupcakes with the remaining mascarpone cream frosting (I used about a tablespoon for each cupcake), and dust lightly with espresso and cocoa powder.
