Preheat oven to 325F and grease a small ramekin with butter or oil.
Add all ingredients to a mixing bowl, stirring until well combined. Transfer brownie mix to the prepped ramekin, top with a few more chocolate chips, and bake for 15-18 minutes. Consistency will have a slightly underbaked texture, bake for 1-2 mins longer for desired consistency.
Dust with powdered sugar and serve immediately. Enjoy!
