Preheat oven to 350. Line an 8 x 8 baking dish with foil and grease it with coconut oil.
In a microwavable bowl combine the coconut oil and chocolate. Microwave in 30 seconds intervals, stirring after each until it is completely melted.
Whisk in the sweetener. Add the egg, vanilla, cocoa powder, xanthan gum, and salt. Stir until smooth. Fold in the chocolate chips. Pour into the prepared baking dish.
Bake at 350 for 25-30 minutes. The top should not jiggle. Do not overbake or they get crumbly.
Cool for an hour. (I know it’s hard to wait but they really need time to cool and set). Lift out the foil and put the foil layer and brownies on a cutting board. Cut into 16 pieces.
