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’ve made a lot of baked goods with bananas, like my Peanut Butter Banana Chocolate Chip Muffins, but I love this banana mug cake because it satisfies my craving for banana bread while also providing portion control. When it comes to banana bread, I can eat 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.

Ingredients

  • 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

Instructions

  • In a microwave-safe mug, add all ingredients except walnuts. Whisk until batter is smooth. Stir in walnuts.
  • 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.

Notes

  • 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. i like it so yay

  2. This turned out great!

  3. Does it work with frozen bananas?

  4. Can I replace the egg with egg whites? It looks delicious!

  5. Wow! I’m so amazed at how well this turned out for a mug cake! Thanks for this recipe, I can’t wait to try some of your other mug recipes!

  6. This was really good! My only substitution was chocolate chips because I didn’t have walnuts. I may try omitting the baking powder next time as I could still taste it. Great recipe for using up ripe bananas 🙂

    • make sure to use an aluminum free baking powder. I wouldn’t recommend omitting it altogether because your cake won’t rise enough

  7. Just tried this without baking powder. It was great! It didn’t rise much, but was still good. I topped with non-dairy whipped cream cold bananas and walnuts. Delish! Thank you for sharing the recipe. ?

  8. Would this recipe work with almond flour instead of coconut flour?

    • Not as a direct substitute. You would have to adjust the liquid measurements and without testing it, I don’t know what those adjustments would be.

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

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