Put the flour, sugar and baking powder in a bowl and mix together. Make a well in the middle and add the remaining ingredients. Work all the ingredients from the middle into a smooth dough.
Divide the dough into 15-20 evenly sized pieces. Shape into a small roll with your hands and flatten it a little. Put the sugar in a plate and roll the rolls in it. Place the rolls on a parchment-lined baking sheet. Bake in the oven preheated to 180 ° C for about 20 minutes.
The cookies stay fresh for a long time in a closed container.
