Wash the lemons, dry them, grate the zest. Squeeze the juice from one lemon. Warm the butter from the refrigerator to room temperature. Cover a baking sheet with parchment.
Break the eggs into a deep bowl and add sugar. Add lemon zest and beat with a mixer until smooth and creamy. Add soft butter to the resulting mixture and pour in lemon juice. Beat everything well again.
Combine flour with baking powder and mix well. Pour the flour mixture into the dough and mix well until all ingredients are completely moistened. The dough turns out soft and tender. Cover the bowl with the dough with the bag and place in the refrigerator for 30 - 40 minutes.
Divide the dough into walnut-sized pieces. Roll into a ball and roll it first in flour and then in powdered sugar. Place on a baking sheet, flattening slightly at a short distance from each other. Bake in the oven at 180°C for 15 minutes.
Dust the cookies with powdered sugar before serving.
