A simple Swedish classic that is ridiculously tasty.

Take 4 dl of oatmeal and mix to a mealy powder in a mixer.
Mix together the ground oatmeal, 150 g of butter, 1½ dl of sugar, 4 tbsp of cocoa powder, 1 tbsp of vanilla sugar and 2 tbsp of cold coffee.
Form round balls and roll them in pearl sugar.
Let chill in the refrigerator before serving.
