Preheat oven to 350 degrees and grease an 8x8 baking pan.
Cut avocado, remove the pit, and scoop the flesh into a mixing bowl.
Add almond butter and mix well until mixture is creamy (about 2-3 minutes).
Add cocoa powder and erythritol, mixing until combined well. Leaving the mixer on, add coconut oil and vanilla and combine.
Add chocolate chips to the mixture and stir to combine.
Spread mixture in the prepare pan. Top with additional chocolate chips if preferred (this will alter nutrition facts).
Bake for 22-25 minutes. Once finished, allow the brownies to cool before serving. Enjoy!
