My favorite cookie recipe is yours this Christmas Eve
Cream together: 1/2 cup butter, 1 cup sugar
Add: 1/2 t vanilla, 1 egg, 1 T lemon zest, 2 T fresh lemon juice
Stir in: 1/4 t baking powder, 1/4 t baking soda, 1 1/2 cups flour.
Refrigerate for at least two hours. Form into small balls, roll in powdered sugar, place on greased baking sheet, squish down with the palm of your hand, and bake 8 minutes at 350 degrees F.
Do not skip the roll-in-powdered-sugar step; necessary to make them turn out “crinkled.”
