Banana Mug Cake Recipe (Gluten-free)

Got a craving for something sweet and delicious? This gluten free banana mug cake takes only 5 minutes to make and is a perfect little treat for one (or for two to share if you're feeling generous!). Tastes exactly like banana bread, but takes a fraction of the time to make it. It's even quite good for you!

Ingredients

  • ½ small banana (ripe is best)
  • 1 small egg
  • 1½ tablespoons brown sugar
  • 2 tablespoons almond butter
  • 2 tablespoons milk (any kind including non dairy)
  • ⅓ cup almond flour (or almond meal/ground almonds)
  • ¼ teaspoon baking soda
  • 1½ tablespoons white chocolate chips (or to taste!)

Instructions

    Cup of Yum
  1. Mash the banana in a very large mug or small baking dish with a fork. Whisk in the egg.
  2. Stir in the sugar, almond butter, and milk.
  3. Stir in the almond flour/meal, the baking soda, and most of the chocolate chips. Sprinkle the remainder of the chocolate chips on the top.
  4. Microwave on full power for 2 minutes. Let cool for a few minutes, then enjoy either plain or with a scoop of ice cream.

Notes

  • How to make: Start by mashing the banana in a big mug or small baking dish. Then whisk in all the other ingredients one by one. Sprinkle a final few white chocolate chips on the top.
  • Cooking time: I find that 2 minutes is about right. You might need to 'test' this in your microwave the first time you make it, however, Start with 90 seconds. If it isn't quite done (a skewer comes out with raw batter on it still) microwave for 30 seconds longer. 
  • Substitutions: You can use regular gluten free flour instead of almond flour if you like. Coconut flour works too, but use just 1.5 tablespoons as it has a drying effect. If you don't have or don't want to use almond butter, any other nut butter works, including peanut butter. If you'd prefer a nut free mug cake, simply replace with 2 tablespoons oil. 
  • To serve: This is a BIG mug cake and easily serves 2. No judgment from me however if you want to eat it all by yourself. Alternatively, it keeps quite well covered in the fridge for a day or two. 
  • More ripe banana recipes: Try banana and carrot muffins, Greek yogurt banana muffins, or air fryer banana bread.
