Preheat oven to 350°F (175°C).
In a mixing bowl, combine almond flour, melted coconut oil, maple syrup, and salt. Press the mixture into a tart pan to form the crust.
Bake the crust for 10 minutes, then let it cool.
In another bowl, mix chopped pecans, maple syrup, coconut sugar, melted coconut oil, beaten eggs, vanilla extract, and salt.
Pour the filling into the cooled crust.
Bake for 35 minutes or until the filling is set.
Let the tart cool before serving.
