Preheat your oven to 350F and line an 8x8-inch pan with parchment paper.
In a bowl, mix together all the crust ingredients until a dough forms. Transfer it to the pan and press it down evenly, making sure the thickness is consistent throughout. I did it using a spatula.
Pop into the oven and bake for 10 minutes.
While the crust is baking, prepare the filling. In a medium bowl, whisk the eggs, then mix in the lemon juice, honey, and coconut flour. Continue whisking until the mixture is smooth with no lumps.
Once the crust is done, take it out of the oven and pour the filling over it. Return it to the oven and bake for another 15 minutes.
Turn off the oven, crack the door open, and let the lemon bars sit inside for 15 minutes to cool gradually. It should prevent the lemon bars from cracking.
Remove from the oven and let cool at room temperature for about 20 minutes, then transfer to the fridge and chill for at least 2 hours.
Slice into 9 squares and serve immediately.
