MARTHA STEWART LEMON SQUARES RECIPES

Steps:

• Heat oven to 325 degrees. In a medium bowl, combine 1 1/2 cups flour and confectioners' sugar. Using a pastry cutter, cut in butter until mixture resembles coarse meal. Gently pat into a 9-by-13-inch glass baking dish, and bake until crust is golden brown, 20 to 25 minutes. Transfer dish to a rack to cool.
• Reduce oven to 300 degrees. Whisk together eggs and granulated sugar in a medium bowl. Add lemon zest and juice, and combine. Sift in remaining 1/2 cup flour, add nuts, and stir to combine. Pour filling onto baked crust, and bake until filling sets, about 40 minutes. Refrigerate until well chilled before slicing, 1 hour and preferably overnight. Dust with confectioners' sugar, slice into pieces with a sharp knife, and serve.

Steps:

• Preheat oven to 350 degrees, with rack in center. Coat a 9-inch square baking pan with cooking spray; line pan with two crisscrossed rectangles of parchment paper, leaving a 2-inch overhang on all sides.
• Make the crust: In a food processor, pulse flour with confectioners' sugar, cornstarch, and salt. Add butter; pulse until mixture resembles coarse crumbs. Press into bottom and 3/4 inch up sides of prepared pan. Refrigerate 15 minutes.
• Bake until crust is lightly browned 20 minutes. Let cool slightly in pan. Reduce oven heat to 325 degrees.
• Meanwhile, make the lemon filling: In a bowl, beat eggs with an electric mixer until thick. Beat in granulated sugar, lemon juice, flour, baking powder, and salt. Pour over warm crust. Bake until set, about 20 minutes. Cool to room temperature; refrigerate about 1 hour.
• Using paper overhang as an aid, lift square from pan. Sift remaining tablespoon confectioners' sugar over the top. Cut into 16 squares.
