Preheat oven ti 350 degrees. In a large bowl combine almond flour, ½ cup chopped pecans, 1 egg, coconut oil, maple syrup, 2 teaspoons vanilla and ½ teaspoon of salt. Spray an 8×8 pyrex dish with coconut oil spray and add the dough, pressing it into an even layer. Bake crust for 15 minutes.
While the crust bakes, start the topping. In a large bowl combine brown rice syrup, coconut sugar, 4 eggs, coconut flour, 2 teaspoons vanilla and 1 teaspoon of salt. Whisk until completely combined then stir in 2 cups of chopped pecans. Pour topping onto crust and cook for 35-40 more minutes or until the filling is firm (with only a slight jiggle when you shake it).
