Mix dry ingredients (except chocolate chips) in a mug
Add in wet ingredients and stir until well combined.
Fold in the chocolate chips.
Place in the microwave for 1 minute. Then continue to bake in the microwave for increments of 10 seconds until the brownies are set and a toothpick comes out clean. (I baked mine for 1 minute and 30 seconds but every microwave is different.)
Let it cool for a few minutes and serve with vegan ice cream. Enjoy!
