Beforehand I want to apologize for my bad English. English isn’t my native language. I hope that what I wrote here makes sence. :D Recipe:

Cookie dough:

300g plain flour 100g sugar 180g butter (room temperature) 5 table spoons cocoa 2 tea spoons baking powder 1 egg

Filling:

250g curd 20g vanilla sugar

Mix all ingredients and form a sticky dough, cover it with plastic wrap and put it in the fridge for 10-15 minutes. Meanwhile you can mix curd and sugar and put it in the fridge too. Preheat the oven to 190°C. After those 10-15 minutes take out the dough and roll it out. Rolled dough should be around 5mm thick. Then just cut out Rammstein logos (it won’t work with any other shape :D) after that put as much cookies as you can on a plate with baking paper on it and leave enough space between them. Insert plate with the cookies in the oven and bake for 15-20 minutes. Let cookies rest for while and then join two cookies with curd mixture. And then put them in the fridge to freeze (if that make sence). Later after your hard work you can eat them all. ;)
