Single serving microwave vegan mug brownie made with healthy ingredients! Fudgy, chewy, melty chocolate goodness. YUM. 



Optional Add-ins: 



  1. Add peanut butter, coconut sugar, 2 tbsp non dairy milk and any of the add-ins in to a mug and stir until combined. Add in the oat flour and cocoa powder and stir until a batter forms. If the batter is too thick, add in the extra tbsp of non dairy milk. Fold in 1 tbsp of chocolate chips. Top with more chocolate chips if desired. 
  2. Microwave on high (1000 W) for 50-60 seconds. The tops should just be cooked it’s okay if the middle is slightly undercooked. Let it stand for 2 minutes (the brownie will continue to cook as you let it stand). Top with fancy salt, vanilla ice cream or coconut whip cream and enjoy!


  • *If you prefer a more cake-y texture, add in 1/4 tsp of baking powder or 1/8 tsp of baking soda.
