Instructions

Crust:

  • Place butter (1 cup) in the freezer for 30 minutes before starting.
  • Grate the frozen butter with a box grater then place it back in the freezer for 10 minutes.
  • Preheat oven to 350 F and line a 9x13 baking dish with parchment paper.
  • In a large bowl, combine the xanthan gum (1 teaspoon), almond flour (2 cups), erythritol (3/4 cup) and lemon zest (1 teaspoon).
  • Add the butter and toss to coat.
  • Sprinkle into prepared baking dish. Use your spatula to smooth out the top so the crust is in an even layer.
  • Bake in the preheated oven for 20-24 minutes until edges of the crust begin to brown.
  • Set aside and cool.

Filling:

  • In a small bowl combine the baking powder (1/2 teaspoon), xanthan gum (1 teaspoon), and almond flour (1/4 cup) and set aside.
  • In a large bowl, whisk the eggs (4 large in size).
  • Add erythritol (1 cup), fresh lemon zest (2 1/2 teaspoons), fresh lemon juice (1/3 cup) and combine.
  • Add almond flour (1/4 cup) mixture and combine.
  • Pour filling over the cooled crust and bake in preheated oven for 25 minutes, or until the center of the filling is set.
  • Allow the bars to cool in the pan.
  • Once cooled, remove from the pan and slice.
  • Sprinkle with powdered erythritol and enjoy!

Notes

  • Almond Flour. Using fine-grained almond flour will yield the most "flour-like" results. My favorite brands are Bob's Red Mill, Trader Joe's, or Costco brands. 
  • Lakanto, Swerve, or Erythritol. I stick to Lakanto and Swerve which are a 1:1 swap with traditional sugar. If using a different brand of Erythritol, keep in mind it's 70% as sweet as sugar, so you may need to add more to taste. 
  • Xanthan Gum is necessary for binding the ingredients of this recipe together, you CAN'T SKIP OR SUB!
