Creating Tiramisu Cupcakes is straightforward if you follow these simple steps:

1. Preheat Oven: Preheat your oven to 350°F (175°C) and line a cupcake pan with paper liners.
2. Mix Dry Ingredients: In a large bowl, sift together the flour, granulated sugar, cocoa powder, baking powder, and salt.
3. Cream Butter and Sugar: In another bowl, cream the softened butter with sugar until light and fluffy.
4. Add Eggs and Vanilla: Beat in the eggs one at a time, followed by the vanilla extract.
5. Combine Wet Ingredients: Gradually add the cooled coffee and milk, mixing until well combined.
6. Combine Mixtures: Slowly add the dry ingredients to the wet mixture, stirring until smooth and no lumps remain.
7. Fill Cupcake Liners: Pour the batter evenly into the prepared cupcake liners, filling each about two-thirds full.
8. Bake: Place in the preheated oven and bake for 20-25 minutes or until a toothpick inserted in the center comes out clean.
9. Cool Cupcakes: Remove from the oven and allow to cool in the pan for 10 minutes before transferring to a wire rack to cool completely.
10. Prepare Frosting: In a separate bowl, beat the mascarpone cheese and powdered sugar until smooth. In another bowl, whip the heavy cream until stiff peaks form.
11. Combine Frostings: Gently fold the whipped cream into the mascarpone mixture until fully combined.
12. Frost Cupcakes: Once the cupcakes are completely cool, pipe or spread the mascarpone frosting on top.
13. Dust with Cocoa: Lightly dust the frosted cupcakes with cocoa powder and add chocolate shavings if desired.
