First, brew the Lavazza coffee so that it has time to cool to room temperature.

In a large bowl, whisk together the egg yolks and sugar until the mixture becomes pale and light. Add in the alcohol or vanilla extract, and beat well. Add in the mascarpone cheese, and mix until no lumps remain.

In a medium bowl, using a hand mixer, beat the whipping cream until fluffy and stiff.

Using a spatula, gently fold the whipped cream into the egg and mascarpone mixture, being careful to not overmix.

When mixture is smooth and well incorporated, add in the cocoa, 1-2 tablespoon at a time, until no lumps of cocoa appear.

Grab a large serving dish, and place one layer of ladyfingers in it. Feel free to trim the cookies to fit! Using a spoon, thoroughly soak the cookies using the Lavazza coffee.

Top cookies with a generous amount of chocolate cream, smooth it down using a spatula, and top with some dark chocolate shavings.

Create another layer of ladyfingers on top, and repeat the process. Depending on the size of the dish, you should get 3-4 layers.

Allow tiramisu to sit in the refrigerator for at least 24 hours before enjoying.
