Keto Lemon Bars

Becky
Sweet, tart, with a chewy yet delicate crust, these keto lemon bars are irresistible and well worth the little bit of time it takes to put them together.

Instructions
 

FOR CRUST:

  • Preheat your oven to 350 degrees and line an 8x8 inch pan with cooking oil and parchment paper. Set aside.
  • In a large bowl, using an electric hand mixer, beat together the butter and erythritol until creamy and well combined. Add the flours and salt and mix until a dough forms.
  • Press the dough evenly into the prepared pan and bake until just lightly golden brown, about 10 minutes. Allow to cool for 30 minutes.
  • Lower oven temperature to 325 degrees.

FOR FILLING:

  • In a small saucepan set over low heat, add lemon juice and erythritol. Heat for 2-3 minutes until dissolved, then remove from heat and cool. 
  • In a large bowl, whisk together eggs, cooled lemon juice mixture, lemon zest, stevia, and vanilla, mixing until well combined. Stir in coconut flour and allow to thicken for about 5 minutes.
  • Pour filling into crust, then bake for 15-20 minutes until the center is slightly wobbly. 
  • Remove from oven and let bars cool to room temperature. Cover and refrigerate 5-6 hours, or overnight.
  • Sprinkle the top with powdered erythritol.

Notes

  • Use Fresh Lemons for this recipe. You want to use fresh lemon juice, not bottled or frozen juice. It just won't taste as good.
  • When zesting your lemon, you want to be careful not to zest any of the white part of the lemon. That part is bitter. Use just the bright, shiny yellow skin. Add extra zest if you want an extra lemony bar.
  • It's important to chill the lemon bars after you bake them. This will allow everything to finish setting. You'll have a difficult time trying to cut the bars if they aren't cold.
  • Top these bars with powdered erythritol or Keto Whipped Cream.
