I’m a huge fan of banana bread, so the idea of being able to whip up a mini banana bread in just a few minutes is super appealing.

This is perfect for a weeknight dessert and makes one serving, so no need to share the deliciousness! Plus, all you need is a microwave.

Ingredients for a Banana Bread Mug Cake

Before you make this recipe, take a peek into your pantry to make sure you have all the ingredients you need to make this banana mug cake.

  • Banana: ideally ripe or softened in the oven
  • Egg
  • Milk: milk alternatives would work fine as well
  • Coconut oil: melted in the microwave
  • Whole wheat flour
  • Brown sugar
  • Baking powder
  • Chocolate chips: I use semi sweet chocolate chips

Tip: Ripe bananas work best for this recipe because they are softer and sweeter than unripe bananas.

How do you make a banana mug cake?

Step 1: In a mug, mash up the banana. Add the egg, milk and melted coconut oil. Stir until well combined.

Step 2: Add whole wheat flour, brown sugar and baking powder. Stir again until well combined.

Step 3: Fold in chocolate chips.

Step 4: Microwave the mug for 2 minutes in 30 second intervals to prevent excessive rising. Then enjoy!

What makes a mug cake rise?

You may notice that the banana mug cake loves to rise in the microwave. If you use too small of a mug, it may even overflow. So what causes this reaction?

The baking powder acts as a leavener in this recipe. It creates small air bubbles which expand the cake and make it rise. Pretty cool right?

So make sure to add baking powder to this recipe or you’ll probably get a pretty flat and dense mug cake, which isn’t great.

Is this a single serving mug cake?

Yes! This recipe makes one single serving. This is perfect if you live on your own or just want a small dessert to satisfy a sweet tooth.

I wouldn’t recommend making more than one serving in a mug because it will likely overflow. If you want to make more than one serving, add one serving to each mug. 

You may even find that a single serving is too much. If you have leftovers, I recommend covering the mug and storing it in the refrigerator for 2-3 days.

Is this banana mug cake healthy?

Yes! This banana mug cake is a healthier option compared to traditional banana bread because it’s higher in fiber and lower in sugar.

That being said, don’t feel like you need to replace regular banana bread with this recipe. Regular banana bread is fine to consume in moderation.

This recipe contains six grams of fiber, 20 grams of added sugar and 17 grams of saturated fat. You can omit the brown sugar or chocolate chips to lower the sugar content and replace the coconut oil with olive, avocado or canola oil to lower the saturated fat content. 

There are also a variety of vitamins and minerals in this recipe. In fact, it’s an excellent source of vitamin B1 (thiamine), B2 (riboflavin), B5 (pantothenic acid), B6 (pyridoxine), B12, copper, magnesium, manganese, phosphorus, selenium and zinc.
