First, the softened butter, sugar and vanilla sugar are whipped until frothy. Add the eggs one by one and stir into the butter mixture.
Put the flour together with the baking powder and the pinch of salt in a bowl and stir everything together a little. In between, add the milk in small quantities. Mix everything with a hand mixer to form an even dough.
Divide the dough into 6 equal parts and fill each part in a separate bowl and color with one of the colors. Pour a teaspoon of each of the different colored dough into each muffin tin.
Put everything in the oven at 180 ° C (top / bottom heat) for 12-15 minutes.
Finally, let the muffins cool down and decorate with sprinkles as needed.
