Lime Bars

2 cups all-purpose flour

½ cup confectioners sugar

½ teaspoon salt

1 cup butter

4 eggs

⅓ cup lime juice

¼ cup all-purpose flour

2 cups white sugar

2 teaspoons grated lime peel, or more to taste

½ teaspoon baking powder

1 drop green food coloring, or as desired

1 ½ cups confectioners sugar

1 tablespoon lime juice

1 teaspoon grated lime peel

Preheat oven to 350 degrees F (175 degrees C). Grease a 12x15-inch baking dish.

Mix 2 cups flour, 1/2 cup confectioners sugar, and salt in a bowl; cut in butter with a pastry cutter until crust mixture resembles crumbs. Pat crust evenly into bottom of the prepared baking dish.

Bake crust in the preheated oven for 10 minutes.

Whisk eggs, 1/3 cup lime juice, 1/4 cup flour, white sugar, 2 teaspoons lime peel, baking powder, and food coloring in a bowl; pour over the crust.

Return baking dish to oven; bake until filling is set, about 25 minutes. Cool thoroughly.

Whisk 1 1/2 cup confectioners sugar, 1 tablespoon lime juice, and 1 teaspoon grated lime peel to make a smooth glaze; spread evenly over cooled lime bars. Let glaze set before serving.
