Lemon Squares

Ingredients:
2¼ cups all-purpose flour, divided
½ tsp baking powder
½ cup powdered sugar
1 cup cold butter, cut into pieces
4 large eggs
2 cups granulated sugar
1 tsp lemon zest
½ cup fresh lemon juice

Directions:

Preheat oven to 350̊F. Line bottom and sides of a 13x9 inch pan with heavy-duty aluminium foil or parchment paper, allowing 2 to 3 inches to extend over sides; lightly grease foil.

Stir together 2 cups flour and ½ cup powdered sugar. Cut in butter using a pastry blender or fork until crumbly. Press mixture onto bottom of prepared pan.

Bake at 350̊F for 20 to 25 minutes or until lightly browned.

Meanwhile, whisk eggs in a large bowl until smooth; whisk in granulated sugar, lemon zest, and lemon juice. Stir together baking powder and remaining ¼ cup flour; whisk into egg mixture. Pour mixture over hot baked crust.

Bake at 350̊F for 25 minutes or until filling is set. Let cool in pan on a wire rack 30 minutes. Lift from pan, using foil sides as handles. Cool completely on a wire rack (about 30 minutes). Remove foil and cut into bars; sprinkle with powdered sugar.
