Preheat oven to 350 degrees.
Line an 8 by 8 baking dish with parchment paper.
Whisk the coconut flour, sesame flour, 1/4 cup sweetener together and salt in a large bowl.
Cut the coconut oil into the dry ingredients with two butter knifes or use food processor and pulse until combined.
Press this mixture onto the parchment paper in an even layer by pressing down as evenly as you can with your hand or the flat bottom of a cup.
Bake for 10 minutes until golden brown.
While the crust is cooking, in a medium bowl, beat the eggs, lime juice, zest, remaining 1 cup sweetener and coconut stevia.
Once the crust is done, remove from oven and pour this egg mixture onto the buttery crust.
Sprinkle coconut flakes evenly over the top and bake for 12-15 minutes or until the center is set.
Allow to cool for 10 minutes then remove by lifting the ends of the parchment paper and place onto a cutting board.
Slice into bars and you can enjoy immediately or give them some chill time in the fridge before serving if you prefer.
Best if kept refrigerated.
