Making Tiramisu Cups is a delightful process, and following these simple steps will ensure success:

1. Brew the coffee and let it cool to room temperature. Add coffee liqueur if desired.
2. In a large mixing bowl, whip the heavy cream until soft peaks form.
3. In another bowl, mix the mascarpone cheese, granulated sugar, and vanilla extract until fully combined and smooth.
4. Gently fold the whipped cream into the mascarpone mixture until well blended. Be careful not to deflate the whipped cream.
5. Dip each ladyfinger briefly into the cooled coffee mixture, ensuring they are soaked but not soggy.
6. Begin layering the cups: Start with a layer of soaked ladyfingers at the bottom.
7. Add a layer of the mascarpone cream mixture on top of the ladyfingers.
8. Repeat the layers, finishing with a layer of mascarpone cream at the top.
9. Cover each cup and refrigerate for at least 4 hours, or overnight for maximum flavor.
10. Before serving, dust the top of each cup with cocoa powder and garnish with chocolate shavings if desired.

These easy steps will guide you in crafting these delightful Tiramisu Cups with minimal fuss!
