Banana Bread Mug Cake (Paleo)

Single serving paleo banana bread mug cake made in the microwave. This cake cooks in about 2 minutes and tastes like fluffy banana bread.

I love making banana mug cake because it satisfies my craving for banana bread while also providing portion control. When it comes to banana bread, I can half of a freshly baked loaf in one sitting.

So for my next paleo mug cake recipe, I decided to tackle banana bread.

This mug cake is fluffy and light. Because bananas are naturally sweet, I only used a little bit of sweetener. I also added walnuts because banana bread just doesn’t taste the same to me without walnuts.

Banana Bread Mug Cake (Paleo)

A single serving banana cake that is also paleo and gluten free.


  • 4 tbsp mashed ripe banana (about 64 grams weighted; approximately 1 small banana)
  • 2 tbsp coconut flour
  • 1/4 tsp baking powder (please note commercial baking powder is not paleo so you may need to make your own homemade paleo baking powder)
  • 1/8 tsp cinnamon
  • 1 large egg
  • 1 tsp olive oil
  • 1 tsp maple syrup
  • 2 tbsp almond milk
  • 1 tbsp chopped walnuts


  1. In a microwave-safe mug, add all ingredients except walnuts. Whisk until batter is smooth. Stir in walnuts.
  2. Cook in the microwave at full power for about 2 minutes or until cake is cooked. Allow cake to cool a few minutes before eating. The banana flavor will be more prominent if you allow the cake to cool for about 15-20 minutes.
This recipe works best with overripe bananas. Make sure to mash them as much as possible. Also keep in mind that 4 tbsp of mashed bananas is more than just 4 tbsp of bananas, so make sure to measure after the bananas have been mashed.

  1. Yum! This was good! Swapped the walnuts for dark chocolate chips, and that was also good! Thanks for the recipe!

  2. can skim milk or 2% be used instead of almond milk?
