Sugar-Free Lemon Bars Recipe


  1. Preheat the oven to 350 degrees. Line a baking pan with parchment paper.
  2. In a large bowl, whisk together the dry crust ingredients (flour, Purecane™ Confectioners Sweetener, and salt). Add in the wet ingredients (room temp butter and vanilla extract) and mix until combined.
  3. Press the crust mixture into the bottom of the pan. Use a butter knife of a spatula to create an even layer.
  4. Bake the crust for 17-20 minutes to brown. Set aside to cool.
  5. While the crust is browning, make your lemon custard by mixing together the dry ingredients in a bowl (Purecane™ zero calorie baking sweetener, flour, and salt). Next, mix the eggs and lemon juice until just combined.
  6. Add your custard on top of your cooled crust. Bake at 350 for 20 minutes.
  7. Allow your lemon bars to cool and set completely before garnishing.
  8. Garnish with a light dusting of Purecane™ Confectioners Sweetener and some lemon zest.
  9. Enjoy!
