You'll use just a tad less than two sticks of butter to make these delicate little gems.
3/4 cup plus 2 Tbsp. butter, softened
1 1/2 cups powdered sugar, divided
1 tablespoon lemon zest
2 tablespoons fresh lemon juice
1 1/2 cups all-purpose flour
1/4 cup cornstarch
1/4 teaspoon table salt
How to Make It
Beat butter at medium speed with a heavy-duty electric stand mixer until creamy. Add 1/2 cup powdered sugar; beat at medium speed until light and fluffy. Stir in zest and juice. Whisk together flour and next 2 ingredients. Gradually add flour mixture to butter mixture, beating at low speed just until blended. Cover and chill 1 hour.
Preheat oven to 350°. Drop dough by level spoonfuls 2 inches apart onto parchment paper-lined baking sheets, using a 1-inch cookie scoop.
Bake at 350° for 13 minutes or until lightly browned around edges. Cool on baking sheets 5 minutes.
Toss together warm cookies and remaining 1 cup powdered sugar in a small bowl.
