Streusel-Topped Lemon Shortbread Bars

Prep time 15 mins
Bake time 1 hr, 8 mins
Yield Makes 32 bars


  • 2 cups all-purpose flour
  • 3 tablespoons sugar
  • 1/2 teaspoon salt
  • 1 cup cold butter, cut into 1/2-inch pieces and divided
  • 2 egg yolks
  • 6 large eggs
  • 2 1/2 cups sugar, divided
  • 1 1/4 cups all-purpose flour, divided
  • 1 teaspoon baking powder
  • 4 teaspoons grated lemon rind
  • 1/2 cup fresh lemon juice
  • 1/4 teaspoon salt
  • Powdered sugar

How to Make It

  1. Combine first 3 ingredients in a food processor. Add 3/4 cup butter pieces to food processor, and pulse 12 to 15 times or until mixture resembles coarse meal; chill remaining 1/4 cup butter pieces. Add egg yolks, and process just until mixture forms clumps. (Clumps will be moist.) Press mixture onto bottom of a lightly greased 13- x 9-inch pan.

  2. Bake at 350° for 16 to 18 minutes or just until golden brown around edges. Remove pan from oven, and reduce temperature to 325°.

  3. Whisk together eggs and 2 cups sugar in a large bowl until blended. Combine 1/2 cup flour and baking powder; whisk into egg mixture until blended. Whisk in 4 tsp. grated lemon rind and 1/2 cup fresh lemon juice. Immediately pour lemon mixture over hot crust in pan.

  4. Bake at 325° for 20 to 25 minutes or until filling is set. Remove from oven.

  5. Combine 1/4 tsp. salt, remaining 1/2 cup sugar, and remaining 3/4 cup flour. Cut in reserved 1/4 cup butter pieces with a pastry blender or fork until crumbly. Sprinkle topping over hot lemon mixture, and bake 25 more minutes or just until lightly golden. Let cool completely on a wire rack. Cut into 32 (1 1/2- x 2-inch) bars, and sprinkle evenly with powdered sugar.
