This chocolate mug cake is a quick and easy single-serving dessert! It’s irresistibly fudgy, moist, fluffy, and packed with chocolate flavor. It’s made with vegan and gluten-free ingredients, like overripe bananas and oat flour. Satisfy your sweet tooth with this healthy mug brownie in less than 5 minutes. You won’t believe how easy it is!


  • 1 small overripe banana, mashed
  • 1 tbsp peanut butter or almond butter
  • 1 tbsp plant-based milk
  • 1 tbsp coconut sugar
  • 1/4 tsp vanilla extract
  • 1/3 cup oat flour
  • 1 tbsp cocoa powder or cacao
  • 1/2 tsp baking powder
  • Pinch of salt
  • 12 tbsp chocolate chips, plus more for topping


  1. Add the overripe banana to a bowl and mash until nearly smooth. Add nut butter, plant-based milk, coconut sugar, and vanilla extract. Mix together.
  2. Add oat flour, cocoa powder, baking powder, and salt to the bowl. Mix together, then add the chocolate chips.
  3. Very lightly grease a mug with coconut oil or non-stick spray. Pour the chocolate batter inside the mug. Top with extra chocolate chips, if desired.
  4. Microwave for 2 minutes. Enjoy!


  • You can combine the ingredients inside the mug, but I recommend using a separate bowl.
  • I recommend using pre-made oat flour, but you can also create your own at home. To create oat flour, simply grind rolled oats inside a food processor until a super fine flour forms.
