Recipe Details
Ingredients
  • 3 Tbsp margarine, softened
  • 3 Tbsp fat-free cream cheese
  • 1 1/2 cup(s) sugar
  • 1 large uncooked egg yolk(s)
  • 3/4 cup(s) all-purpose flour
  • 2 Tbsp all-purpose flour
  • 3 Tbsp powdered sugar
  • 1 large egg(s)
  • 1/4 cup(s) regular liquid egg substitute
  • 1/3 cup(s) fresh lime juice, or to taste, from Key limes
Instructions
  1. Preheat oven to 350ºF. Coat an 8-inch square baking dish with cooking spray.
  2. To make the crust, beat margarine, cream cheese and 1/2 cup of sugar with an electric mixer until light and fluffy. Beat in egg yolk and gradually add 3/4 cup of flour. Spread into baking dish using your hands (coat hands with 1 tablespoon of powdered sugar to prevent batter from sticking). Bake until crust is lightly browned, about 15 minutes.
  3. To make the filling, beat egg and egg substitute in the same bowl used to make crust. Add remaining 1 cup of sugar and 2 tablespoons of flour; beat on low speed until blended. Add lime juice; beat on low speed until blended. Pour onto warm crust and bake 15 minutes more.
  4. Cool on a rack. Sprinkle with 2 tablespoons powdered sugar and cut into 16 pieces.
