2 cups all-purpose flour
1 cup butter
1/2 cup powdered sugar
4 large eggs, beaten
1/4 cup all-purpose flour
1/3 cup key lime juice
2 cups sugar
1/2 teaspoon baking powder
Preparation:
Combine first three ingredients and press into a 9x13x2-inch baking pan. Bake at 350° for 20 minutes or until golden brown. Mix the remaining ingredients and pour over baked crust. Place in 350° oven again and bake for approximately 30 minutes or until filling is set. If needed, cover with foil and bake longer than 30 minutes to ensure a complete baked filling but not a burned top! Let cool completely and sift with additional powdered sugar. Cut key lime bars into squares.
