Preheat the oven to 350° and line a cookie sheet with parchment paper. Set aside.
In a large bowl, combine the coconut oil, almond butter, coconut sugar, salt, egg, and vanilla. Stir well until fully mixed. Add in the almond flour until a dough is formed and it is mixed evenly.
Using a 1 tablespoon measuring spoon, scoop the dough and form it into a thin, long log. Place it on the cookie sheet and repeat until the cookie sheet is full, leaving about 1 inch between each cookie.
Use a fork to press the indentations on the cookie and gently squeeze the center inward to form a peanut shape. Bake for 15 minutes and let cool completely.
Once the cookies are cooled, make the filling. In a medium bowl, combine the almond butter, maple syrup, coconut oil, and salt.
Mix until smooth and spread on half the cookies then top them with the remaining cookies- creating a sandwich.
