Preheat the oven to 350°F. Grease a mini cast-iron skillet with coconut oil or prepare a baking sheet with coconut oil, parchment paper, or a silicone mat.
Place the almond flour, brown sugar, pecans, chocolate chips, baking soda, and salt in a large mixing bowl. Mix together so that everything is combined.
Add the coconut oil, egg, and vanilla extract and mix in with a spatula or spoon. It will take a moment to get everything mixed in well and to form a nice dough.
Put the dough in your prepared skillet or form 2 large dough balls and place them on your baking sheet. Bake the skillet cookie for 20-22 minutes (if you are making cookies, bake for 11-13 minutes). Once done, allow the cookie to cool for a few minutes before serving. For cookies, allow them to cool on the baking sheet for 5-10 minutes so that they can firm up before serving. Enjoy!
