100 g butter, 2 tbsp sugar, 1 pc egg
Add ground cinnamon and crushed orange zest.
1 tbsp zest, ½ tsp cinnamon
Punch the ingredients until smooth.
Add flour and baking powder.
170 g flour, 1 tsp baking powder
Mix. The dough will be very soft. Put it in a cellophane bag and put it in the refrigerator for an hour. The oil will harden and the mass will noticeably thicken. In any case, it will not be difficult to pour the missing flour later, but if the dough turns out to be excessively thick, the cookies will not turn out soft and crumbly.
Transfer to a baking sheet. Bake in the oven at 170° for 15-17 minutes.
Orange stars with cinnamon are ready. The cookies are soft and fragrant. Enjoy your meal!
