Ingredients
Method
- Make the Cupcakes
- Preheat the oven to 350°F (175°C). Line a 12-cup muffin tin with cupcake liners.
- In a bowl, whisk together flour, baking powder, baking soda, and salt.
- In another bowl, beat the butter and sugar until creamy and light, about 2–3 minutes.
- Add the eggs, one at a time, mixing well after each addition.
- Mix in the milk, sour cream, and vanilla until smooth.
- Add the dry ingredients to the wet mixture and stir until just combined.
- Divide the batter into cupcake liners, filling each about 2/3 full.
- Bake for 16–18 minutes, or until a toothpick comes out clean.
- Transfer to a cooling rack and allow to cool fully.
- Add the Coffee Soak
- Mix the coffee and liqueur (if using).
- Use a toothpick to poke holes in each cupcake.
- Spoon 1–2 tsp of coffee mixture over each cupcake to soak in.
- Make the Mascarpone Frosting
- In a mixing bowl, beat the heavy cream until soft peaks form.
- Add the mascarpone, powdered sugar, and vanilla, and beat until thick, smooth, and pipeable.
- Transfer to a piping bag with a round or star tip.
- Assemble
- Pipe the frosting generously onto each cupcake.
- Dust lightly with cocoa powder before serving.
Notes
For stronger coffee flavor, brush the cupcakes twice with the coffee soak.
Keep cupcakes refrigerated, but let them sit 10–15 minutes at room temperature before serving.
Mascarpone must be cold to prevent the frosting from becoming runny.
For a festive look (Halloween or party theme), add chocolate curls, mini ladyfingers, or edible decorations.
Can be made one day ahead — flavors deepen overnight.
