Ingredients
Method
- In a large mixing bowl combine the egg yolks, sugar, lemon zest and vanilla extract. Whisk until all the ingredients are incorporated. Add soften butter and whisk again.
- Add the flour, baking powder and salt and start mixing with a spatula. When the flour has absorbed all the liquid ingredients, add the sour cream and keep mixing the dough. When mixing with a spatula becomes too hard to do, start kneading the dough with your hands. The dough should turn out very soft and not stick to your hands.
- To form the cookies, tear off a small piece of dough and roll into a ball the size of a walnut. Flatten it a little and place on the baking sheet covered with parchment paper or Teflon sheet. Bake it at 350 F degrees for 15-18 minutes. Let them cool completely and dust with the powdered sugar.
