Heat the oven to 175°C (350°F)
Soften the butter in the microwave for a few seconds
Mix all dry ingredients first, then add the rest.
Use a hand mixer with the dough hooks and mix everything until it is possible to combine it to a ball with your hands
Line a baking sheet with parchment paper
Divide the dough in 4 and spread them out in lines across the sheet (they expand slighlty so leave some space between).
Carefully roll them out and even out the edges.
Bake for 15 min, take it out of the oven and start cutting the cookies while it is still hot. Make the cuts slightly slanted to get the classical look of the Swedish kolasnittar
