Melt the butter in a bowl, add the vegetable oil, beer, salt, and sugar. Stir, then add the flour in parts and knead into a dough.

Gather the dough into a ball and chill in the fridge for one hour. Then roll it out into a thin sheet, sprinkle with sugar if you like, and cut into pieces.

Arrange the cookies on a baking tray and bake for 15 minutes at 180-200°C.

Let the finished cookies cool. Enjoy!
