Old-Fashioned Lemon Bars

Soft and custard-y old-fashioned lemon bars topped with lots of powdered xylitol. These bars are a snap to prepare and even funner to eat!
Prep Time 10 minutes
Cook Time 40 minutes
Total Time 50 minutes
Servings 1 dozen bars


  • CRUST:
  • 1/2 cup butter softened
  • 1/2 cup sour cream
  • 1/4 cup powdered xylitol
  • 1-1/2 cups white whole wheat flour
  • 4 large eggs
  • 1/3 cup lemon juice
  • 1 tablespoon grated lemon zest
  • 3/4 cup xylitol
  • 1/4 cup white whole wheat flour
  • Powdered xylitol for sprinkling


  • Prepare the crust: In a medium bowl, whisk butter, sour cream, and xylitol until smooth. Stir in flour until a ball of dough forms. Press dough evenly into a greased 9x13 baking pan. Prick dough all over with a fork. Bake crust at 350F 20 minutes, or until lightly browned.
  • While crust bakes, prepare the filling: In a medium bowl, whisk eggs, lemon juice, zest, xylitol, and flour until smooth. Pour evenly over pre-baked crust. Return pan to oven and bake at 350F for an additional 20 minutes, or until filling is set. (filling may puff up a little bit---don't worry, it will deflate while it cools) Cool bars on a wire cooling rack completely before cutting and sprinkling with extra powdered xylitol.


Store lemon bars in refrigerator up to 4 days.
