Method
- Preheat oven to 350°F (175°C). Line a baking sheet with parchment paper.
- In a bowl, cream butter and powdered sugar until light and fluffy.
- Mix in egg yolk, vanilla, flour, cornstarch, and salt until dough forms.
- Roll dough into small balls and flatten slightly onto baking sheet.
- Bake for 10–12 minutes until lightly golden. Cool completely.
- For the filling, whisk mascarpone, powdered sugar, espresso, and cocoa until smooth.
- Pipe or spread filling onto one cookie and top with another to form sandwiches.
- Dust tops lightly with cocoa powder.
- Serve immediately or refrigerate for 1–2 hours for firmer filling.
Notes
For an extra tiramisu touch, lightly brush cookies with cooled espresso before filling. Store chilled for best results.
