Chocolate Tiramisu Cupcakes

Make the Chocolate Cupcakes

Preheat your oven to 350°F (175°C) and line a cupcake tin with cupcake liners.
In a large mixing bowl, whisk together the flour, sugar, cocoa powder, baking powder, baking soda, and salt until well combined.
In another bowl, combine the egg, milk, vegetable oil, and vanilla extract. Mix until smooth.
Gradually add the wet ingredients to the dry ingredients, mixing until just combined.
Carefully stir in the boiling water. The batter will be thin, but this is normal.
Pour the batter into the prepared cupcake liners, filling each about 2/3 full.
Bake in the preheated oven for 18-20 minutes, or until a toothpick inserted into the center comes out clean.
Remove from the oven and allow to cool in the tin for 5 minutes before transferring to a cooling rack.

Prepare the Coffee Syrup

In a small bowl, combine the cooled brewed coffee and granulated sugar. Stir until the sugar is dissolved.
Once the cupcakes are completely cooled, use a toothpick to poke holes in the tops of each cupcake.
Brush the coffee syrup generously over the tops of the cupcakes, allowing it to soak in.

Make the Mascarpone Frosting

In a mixing bowl, combine the mascarpone cheese, heavy cream, powdered sugar, and vanilla extract.
Using an electric mixer, beat on medium speed until soft peaks form. Be careful not to overmix, as it can become grainy.
Transfer the frosting to a piping bag fitted with a star tip.
Pipe the frosting onto the cooled cupcakes in a swirl pattern.
Dust with cocoa powder before serving.
