For the crust:

For the topping:

  • 4 Eggs
  • 2 tsp Lemon zest
  • 3/4 Cup Fresh lemon juice (about 6 large juicy lemons)
  • 1/2 Cup Monkfruit
  • 1 1/2 tsp Coconut flour, sifted


  • Preheat your oven to 350 degrees and generously rub an 8x8 inch pan with coconut oil. Set aside.
  • In a large bowl, using an electric hand mixer, beat together the monkfruit, coconut oil and pinch of salt until creamy and well combined. Stir in the coconut flour until a dough forms.
  • Press the dough evenly into the prepared pan and bake until just lightly golden brown, about 10 minutes.  Once cooked, let cool for 30 minutes.
  • Lower the temperature of your oven to 325 degrees  and ensure the oven rack is in the middle of the oven.
  • Once the crust has cooled, gently whisk together the eggs and lemon zest in a large bowl. Do NOT use an electric mixer here or you will over-beat the eggs and the topping with crack once baked. Use a hand whisk.
  • In a separate, medium bowl, lightly heat the lemon juice (I used a microwave.) Whisk in the monkfruit and stir until it is dissolved. Whisk the coconut flour into the lemon juice mixture, 1/2 tsp at a time, until well mixed. Make sure you continually whisk as you add the flour so that it doesn't clump up.
  • Pour the lemon juice mixture into the egg mixture, whisking while you pour, until evenly combined.
  • Pour the topping over top of the cooled crust and bake until it is just set, and the very center is just slightly jiggly, about 20-22 minutes. Let cool completely at room temperature. Then, cover and refrigerate for at least 6 hours, best over-night. You need to let the crust completely cool, or it will be soft.
  • Using a VERY sharp knife (or else you might not cut through the crust) cut the bars into squares and DEVOUR. ***

**As with all GF baking, please weigh your flour to ensure results
*** The first bar is a little difficult to get out, so be gentle! But, once one is out, it's smooth sailing!
Store bars in the refrigerator until ready to serve. Monkfruit does become grainy as it cools and sits for a long term, so bars are best made as close to serving as possible (keeping chilling time in mind)
