Preheat the oven to 350 degrees F. Generously grease a large cast iron skillet (I used a 10inch) with coconut oil, butter or ghee. Set aside.
In a medium sized bowl, mix together the dry ingredients: almond flour, cacao powder, baking soda, and sea salt.
In a larger bowl, using an electric mixer, beat together the melted coconut oil, coconut sugar, cashew butter, eggs, and real maple syrup. Slowly fold in the dry ingredients and gently mix until well combined. Stir in chocolate chips.
Using a spatula, pour the batter into the prepared skillet (It will be slightly thick). Spread around to even out the top. Sprinkle with more chocolate chips if desired.
Transfer to the oven and bake for 20-25 minutes (this will depend on the size of skillet, and how gooey you want your brownies!) If using larger than 10 inch skillet, pull out the skillet at 20 minutes. If using a 10 inch or smaller, this may require a few extra minutes.
