Knead the butter, sugar
and flour and a pinch of salt together and divide the dough in two equal
parts. Add the cacao to one part. Put the dough in the fridge for half
an hour. Roll both the white and the brown dough into two long thin
rolls, so you have four rolls. Lay a brown and a white one together
and push softly with your hand until they stick. Put a brown one on
top of the white and a white one on top of the brown. Now cut slices
and put them on the oven tray. Bake 20 minutes at 180 degrees
Celsius.
