Line a 6x6' pan with parchment paper and set aside.
Whisk together flour, powdered sugar, cocoa powder, instant coffee, baking powder and salt in a medium sized bowl.
In a large mixing bowl combine sugar, oil, chocolate chips, and vanilla.
Microwave your sugar and oil mixture for 45 seconds. Mix well and allow this to cool fully.
Once fully cooled whisk in your egg.
Slowly add in your flour mixture until just combined.
Pour brownie batter into prepared baking pan and cover with aluminum foil.
Preheat your air fryer to 325 degrees (or let it run at that temp for ~3-5 minutes if you don't have a preheat function)
Bake in the air fryer for a total of 20 minutes. Cook your brownies with the aluminum foil on top for the first 15 minutes, then remove the foil for the last 5 minutes.
Remove brownies from air fryer, allow to cool fully, cut and enjoy!
