Ingredients

  • 1/4 cup butter melted
  • 1.5 cups pecans finely chopped
  • 3 tablespoons confectioners sugar substitute
  • 4 eggs
  • 4 egg yolks
  • 1/2 cup confectioners sugar substitute divided
  • 1/2 cup lemon juice
  • 1 tablespoon lemon zest
  • 1 teaspoon lemon extract
  • 2 tablespoons egg whites
  • 1/4 teaspoon salt
  • 2 tablespoons butter room temperature

Instructions

  • Spray an 8x11 baking dish with cooking spray. Preheat the oven to 350. Add finely chopped pecans to baking dish and stir in confectioners sugar substitute, mixing well. Add melted butter and combine until coated. Press into an even layer on bottom of baking dish. Bake for 15 minutes and allow to completely cool.
    1.5 cups pecans, 3 tablespoons confectioners sugar substitute, 1/4 cup butter
  • In a large mixing bowl, whisk eggs, egg yolks, 1/4 cup of the sugar substitute and 2 tsps of egg whites until frothy and smooth.
    4 eggs, 4 egg yolks, 1/2 cup confectioners sugar substitute, 2 tablespoons egg whites
  • In a medium boiler over low heat, combine other 1/4 cup of sugar replacement, lemon juice, lemon zest, lemon extract and salt. Cook for a minute or so over low heat until sugar has dissolved. Do not boil.
    1/2 cup lemon juice, 1 tablespoon lemon zest, 1 teaspoon lemon extract, 1/4 teaspoon salt
  • Take a small amount of warmed lemon juice and add to egg mixture. Stir to gently temper the eggs. Once egg mixture is warm, add all of it into the remaining juice mixture in the boiler. Cook while whisking over low heat until custard is thick and smooth. Remove from the heat and add in room temperature butter. Continue to whisk to incorporate butter and help cool and thicken custard.
    2 tablespoons butter
  • Pour mixture over cooled crust, smoothing out into an even layer. Cover with plastic wrap and refrigerate for at least 4 hours to set. Cut into bars and serve.
