I have tried this recipe also with spoiled milk and it worked fantastically!

Ingredients
- 210gr flour
- 20gr sugar
- 2 teaspoons baking powder
- 1 pinch salt
- 130ml sour milk
- 20gr butter in room temperature
Steps
- Preheat the oven in 170 degrees Celsius
- Shift the flour and baking powder and mix it with sugar and salt
- Add the sour milk and mix
- Add in small portions the butter and knead the dough
- Add a baking paper in your tray and make small balls (12 pieces), that in the end you push them a bit in order to become a bit flat
- Optionally you can sprinkle them with sugar and cinnamon
- Bake theme till they become slightly golden
