Ingredients:
- 1 cup (2 sticks) butter, softened
- 1½ cups granulated sugar (plus extra for rolling)
- 1 egg, at room temperature
- 2¼ cups all-purpose flour
- ½ teaspoon baking powder
- ½ teaspoon Kosher salt
- 1 teaspoon vanilla
- zest of two large lemons
- 1 tablespoon lemon juice
Method:
- Preheat oven to 350º F. Line cookie sheets with parchment paper or a nonstick baking mat (don’t skip this step! Spray will not work!).
- Cream together butter and granulated sugar until light and fluffy, about 3 minutes. Add egg and mix until well-combined.
- Stir in flour, baking powder, salt, vanilla, lemon zest and lemon juice. Refrigerate for about 20 minutes to allow lemon flavor to develop and to firm up the dough.
- Scoop cookie dough by the tablespoon full and roll into a ball. Roll each dough ball in additional sugar.
- Place cookie dough onto baking sheet, spacing about 1½-inches to 2 inches apart. Lightly press each cookie down. Bake for 10 to 12 minutes or until lightly browned.
