  • ¼ cup almond flour
  • 4 large eggs beaten
  • 4 lemons zested and juiced
  • ¼ tsp xanthan gum

  • Preheat oven at 350°F.
  • In a large bowl, add all the ingredients for the crust and combine well. Mix the dry ingredients first before adding the wet ingredients.

  • After baking let it cool and sit for at least one hour.
  • After it's cooled completely, cover and refrigerate for at least 2-3 hours.
  • When it's ready, take out of the refrigerator and remove the lemon bars from the baking dish and place on a cutting board. Cut into 12 square bars.
