Prepare the Cream Mixture:

In a mixing bowl, whip the heavy cream until soft peaks form. In another bowl, combine the mascarpone, sugar, and vanilla extract. Fold the whipped cream into the mascarpone mixture until smooth and creamy.

Prepare the Coffee:

In a shallow dish, mix the brewed espresso and coffee liqueur (if using).

Dip the Ladyfingers:

Quickly dip each ladyfinger into the coffee mixture, ensuring they’re soaked but not overly saturated.

Assemble the Tiramisu:

Arrange a layer of soaked ladyfingers in the bottom of an 8x8-inch baking dish. Spread half of the mascarpone cream mixture over the ladyfingers. Repeat with another layer of soaked ladyfingers and the remaining mascarpone cream.

Chill:

Cover and refrigerate the tiramisu for at least 4 hours, or overnight for best results.

Add the Topping:

Before serving, dust the top of the tiramisu with cocoa powder using a sifter. Garnish with chocolate shavings if desired.

Serve:

Slice and serve chilled. Enjoy this elegant and creamy dessert!
