Firstly, blend the powdered sugar with the butter, until it’s smooth and fluffy.

Add the egg yolks to the mixture one by one.

Add the flour, the vanilla sugar and the lemon zest. Blend well, until you get a smooth and a bit sticky dough.

Pour the mixture into a piping bag, and pipe out 2-3cm cookies. Put them on a baking tray which is lined with baking paper. Pop them into the oven for 10-12 minutes at 180ºC. Leave them to cool.

Spread jam on the bottom part of the cookies and stick them together.

Finally melt the dark chocolate and with the help of a spoon dribble it over the cookies. Wait until the chocolate has cooled down and you can serve them!
