In a mixing bowl, combine almond flour, melted coconut oil, maple syrup, and a pinch of salt, stirring until well blended. Mix until it forms a dough-like consistency.
Line an 8x8-inch baking pan with parchment paper and press the dough evenly into the bottom of the pan.
Bake the crust for 10-12 minutes, or until it reaches a light golden hue. Take it out of the oven and let it cool to room temperature before handling.
In a medium saucepan over medium heat, combine maple syrup, brown sugar, and coconut oil. Stir constantly until the mixture thickens slightly, which should take approximately 5-7 minutes.
Remove from heat and stir in the pecan halves, vanilla extract, and a pinch of salt.
Spread the pecan filling evenly over the baked crust, using a spatula to smooth it out.
Return the pan to the oven and bake for an additional 20-25 minutes, or until the filling is set but still slightly gooey.
Allow the bars to cool completely at room temperature, then refrigerate for 1-2 hours before slicing to get clean, tidy pieces.
