Ingredients

Crust

  • cup coconut oil
  • ¼ cup honey or maple syrup
  • 1 teaspoon vanilla extract
  • 1 ½ cups almond flour
  • cup coconut flour
  • ¼ teaspoon salt

Filling

  • 4 large eggs room temperature
  • ½ cup honey or maple syrup
  • ½ cup lemon juice from 3-4 large lemons
  • zest from one lemon about 1 tablespoon of zest
  • 3 tablespoons tapioca flour

Instructions

  • Preheat the oven to 350F/177C. To make the crust, whisk together the coconut oil, honey, and vanilla extract in a large bowl. Add the almond flour, coconut flour, and salt. Stir together or use your hands to mix everything together, until you have a crumbly dough.

  • Pour the dough into an 8x8-inch baking pan lined with parchment paper. Use your hands to press the dough flat in the pan. Make sure it's pressed down very firmly.

  • Bake the base crust for 13-15 minutes in the oven, or until lightly golden on top and slightly darker around the edges, then remove.
  • The order of whisking the filling is important. Whisk the eggs and honey together in a bowl until smooth. Add the lemon juice and lemon zest and whisk again. Then add the tapioca flour and whisk again, until smooth, and no flour clumps remain.

  • Let the pan cool on the counter for an hour, then transfer to the fridge and let cool another 2 hours before serving, to firm up. Slice into bars and serve plain, or with a dusting of powdered sugar.
