Preheat oven to 350°F (175°C) and line an 8x8 inch baking pan with parchment paper.
In a medium bowl, combine almond flour, melted coconut oil, maple syrup, and sea salt until a dough forms.
Press the dough firmly into the bottom of the prepared pan.
Bake the crust for 12-15 minutes or until the edges are lightly golden brown.
While the crust bakes, whisk together eggs, lemon juice, lemon zest, honey, and coconut flour in a bowl until smooth.
Remove the crust from the oven and pour the lemon filling over the warm crust.
Return to the oven and bake for an additional 18-20 minutes until the center is set.
Allow the bars to cool completely at room temperature, then refrigerate for at least 2 hours before slicing into squares.
