The Best Lemon Squares Recipes

Steps:

• Preheat oven to 350 degrees F (175 degrees C).
• In a medium bowl, blend together softened butter, 2 cups flour and 1/2 cup sugar. Press into the bottom of an ungreased 9x13 inch pan.
• Bake for 15 to 20 minutes in the preheated oven, or until firm and golden. In another bowl, whisk together the remaining 1 1/2 cups sugar and 1/4 cup flour. Whisk in the eggs and lemon juice. Pour over the baked crust.
• Bake for an additional 20 minutes in the preheated oven. The bars will firm up as they cool. For a festive tray, make another pan using limes instead of lemons and adding a drop of green food coloring to give a very pale green. After both pans have cooled, cut into uniform 2 inch squares and arrange in a checker board fashion.

Steps:

• Preheat the oven to 350 degrees F. Line a 9-by-13-inch baking pan with foil, leaving an overhang on 2 sides; spray lightly with nonstick cooking spray. Set aside.
• For the crust: Add the flour, cornstarch, confectioners' sugar and salt to the bowl of a food processor and pulse 10 times until combined. Add the cold butter and pulse until the mixture looks like coarse sand, about 30 times. (The dough will not come together in one mass.) Sprinkle the mixture evenly in the prepared pan and lightly pat it down. Bake, rotating the pan halfway through, until golden brown around the edges, 20 to 25 minutes.
• For the filling: Combine the eggs, yolks, sugar, flour, salt and lemon juice in a medium saucepan. Whisk continuously over medium heat, occasionally scraping down the sides and edges of the pan with a rubber spatula, until simmering and thickened, 4 to 5 minutes. Remove from the heat and whisk in the lemon zest and butter until combined.
• Lower the oven temperature to 300 degrees F. Pour the filling over the crust and bake until just set, 12 to 15 minutes.
