First of all, combine the flour with the cold butter.

Add the rest of the ingredients to the mixture, 2 egg yolks, powdered sugar and vanilla sugar. Blend it all well into the mixture.

Cover it with cling-wrap and put it into the fridge for 30 minutes.

Roll out the cookie dough with a rolling pin. Use a circle shaped cookie cutter to cut out the cookies.

Now it’s time to whip up the egg whites. Combine the egg whites with the powdered sugar and whisk them for about 20-25 minutes. Then pour the whisked egg whites into a piping bag.

Pipe the egg whites onto the cut-out pastry, so it nearly covers the top of the whole cookie. Then bake them for 10-12 minutes at 180ºC. After taking them out of the oven let them cool.

Stick the bottoms of the cookies together with apricot jam. And voila! You can now enjoy your tasty cookies!
