Tiramisu

Prepare the coffee and let it cool.

Separate the egg yolks from the whites.
Beat the egg yolks with the sugar until the mixture is light and fluffy.
Add the mascarpone to the egg yolks and mix until smooth.

In a separate bowl, beat the egg whites until stiff peaks form.
Gently fold the egg whites into the mascarpone mixture.

Layer the bottom of a dish with the mascarpone mixture.
Dip the biscuits into the coffee and layer them in the bottom of a dish.
Repeat the layers until all the mascarpone mixture and biscuits are used.
Sprinkle the top with cocoa powder.
