About to try these for the first time but we're using lime instead of lemon. The original recipe is here from Taste of Home.
3/4 cup butter, softened
2/3 cup powdered sugar
1½ cups + 3 tablespoons all purpose flour, divided
3 large eggs
1½ cups sugar
¼ cup lemon juice
extra powdered sugar
Preheat oven to 350°. In a large bowl, beat butter and powdered sugar until blended. Gradually beat in 1½ cups flour. Press into bottom of a greased 9x13 baking pan. Bake 18-20 minutes or until golden brown.
In a small bowl, whisk eggs, sugar, lemon juice, and remaining flour until frothy; pour over hot crust.
Bake 20-25 minutes or until lemon mixture is set and lightly browned. Cool completely on a wire rack. Dust with additional powdered sugar. Cut into bars. Refrigerate leftovers. Yield: 4 dozen.
