Banana Bread Muffin in a Mug

This easy banana bread muffin recipe is made with only 5 ingredients and ready in under 5 minutes! This healthy muffin in a mug has no oil, egg or sugar. The ingredients are simple: ripe bananas, flour, baking powder, vanilla and a pinch of salt. These microwave mug muffins are mini and perfect if you’re baking for one or don’t have much time. Of course, if you want to whip up a batch, you can make these banana bread muffins or my favorite banana nut bread recipe.

My bananas were so ripe they were black, which makes them sweet enough that you don’t even need to add sugar. But if you want to add some, one teaspoon is more than enough. I tried them with and without oil, and both worked out great, so I am skipping the oil. Of course, if you want to add it, you certainly can. Just mix in coconut oil in with the bananas.

So far, I have tested them plain and with peanut butter, chocolate chips and nuts. I’d love to see what variations you come up with. Leave your comments below!

Helpful Tips:

  • Make sure you use a microwave safe mug.
  • I used an espresso mug which was the perfect size for a half banana. A ramekin would also work.
  • To use a whole banana double the recipe and use a larger coffee mug.
  • For an espresso-size mug this took 90 seconds in my microwave. If you make double, increase the time to about 2 minutes.
  • You will know when it’s done when the center is no longer wet.
  • Oven Directions: If you don’t have a microwave, you can bake this in a preheated oven in a ramekin of cupcake liner. Bake until the tops are golden and a toothpick inserted in the center comes out clean, 325F for 25 to 30 minutes.
  • Air Fryer Directions: If you want to bake this in the air fryer, preheat the air fryer to 300°F. Bake until the tops are golden and a toothpick inserted in the center comes out clean, about 15 minutes. Let cool before eating.
