In a bowl add the yolks, the sugar and the vanilla and beat with an electric mixer until foamy.

In a second bowl beat the cream and the stabilizer until stiff.

Add the mascarpone to the yolks and mix well.

Carefully add the whipping cream and fold it in until it's fully incorporated. Set aside.

Take a square or rectangle dish and line the bottom with a layer of ladyfingers. Carefully pour some coffee over the biscuits until they are soaked and almost soft throughout.

Spread half of the mascarpone mixture over the biscuits.

Add another layer of ladyfingers on top and soak them again with some spoonfulls of coffee.

Finish the tiramisu with the remaining mascarpone mixture and spread evenly.

Put some clingfilm over the tiramisu and chill for at least four hours or until set.

Dust with the cocoa before serving. Enjoy!
