Ingredients for banana bread mug cake

HEre are the ingredients you will need for this banana bread mug cake recipe, make sure to scroll down to the recipe card for the full detailed ingredient list.

  • Butter- You will need a little bit of butter then you will need to melt directly in the mug where you will be making your banana mug cake.
  • Brown sugar– The brown sugar will lightly sweeten the mug cake and add more moisture to it as well.
  • Egg yolk– You will need one egg yolk for this mug cake.
  • VanillaA little vanilla goes a long way to brighten up your banana mug cake.
  • Milk– The milk is used to make the mug cake moist as well.
  • Banana– Use a very ripe small banana for this recipe.
  • Flour– Regular all-purpose flour works great for this recipe.
  • Salt– I always like adding some salt to my baked goods to balance out the sweetness.
  • Baking powder– The baking powder is the leavening agent used in this recipe.
  • WalnutsIf my banana bread doesn’t have walnuts, I don’t want it! But hey if you’re not a nut in your banana bread kinda person, it’s all good, you can omit

Ingredient substitution

I understand that sometimes, you might not have all the ingredients on hand. Here are a few substitutions that will work just as well.

  • Granulated sugar instead of brown sugar- This will work just as well but will slightly change the flavor.
  • Pecans or other nuts instead of walnuts– I almost prefer pecans over walnuts in my banana bread but either or works ๐Ÿ™‚
  • Chocolate chips instead of walnuts- Okay, hear me out! I get it, not everyone is a nut person, so if you still wanna treat yourself but without the nuts, add chocolate chips instead. You can thank me later!
  • Heavy cream or half and half instead of regular milk- You can even use dairy-free milk. This is just used to give your mug cake more moisture.

What type of banana should I use for banana bread?

When making banana bread, the best type of banana you can use has to be an overripe banana. You know those bananas that are just hanging out on the counter of your kitchen getting darker and darker by the hour.

Those are softer and easier to mash, they are also a whole lot sweeter and have a stronger banana flavor to make your banana bread mug cake taste even better!

How to mash banana for banana bread?

The possibilities are endless when it comes to mashing your bananas for banana bread. Since we are making a single-serve dessert, I would recommend that you mash it with a fork in a bowl.

I personally enjoy having little chunks of banana leftover but that’s a preference thing. The most important thing is that you start with an overly ripe banana and mash it to your likings before adding it to the rest of the batter.

How to make a banana bread mug cake in the microwave?

Here is how you can make your own banana bread mug cake in the microwave. Make sure to scroll down to the recipe cake to get the full instructions and ingredient list.

  • Melt the butter in the same mug you are going to bake your banana bread cake in.
  • Add in the brown sugar and egg yolk, then milk and the mashed banana and mix until combined.
  • Add in the dry ingredients (flour, salt, baking powder, and walnuts) and mix one last time.
  • Bake in the microwave.
  • ENJOY!

Can I bake a mug cake in the oven?

Unfortunately no, unless specified otherwise.

This mug cake recipe is specifically made to make your life easier and be baked extra fast in the microwave. Plus who wants to turn on a whole oven. and wait for it to preheat for just one serving. That’s why the microwave is a god send!

What can I top my banana bread cake with?

Topping your banana mug cake might be one of the most fun part of this whole recipe if I can say so myself. Here are a few ideas that you can use next time you make this for yourself:

  • Nutella- Are you freaking kidding me!! Imagine adding something amazing to something that’s already extra amazing! That’s what I live for TBH.
  • Ice cream– You can never go wrong with topping literally anything with a generous scoop of your favorite vanilla ice cream. In my case some Tillamook sweet cream ice cream … Ohmygerddd!!! So good!
  • Caramel– Caramel and bananas are a match made in heaven so topping your banana mug cake with caramel seems only logical at this point!
  • Candied nuts– Candied nuts on banana bread is what will make this treat a next level delicacy. Try it out!
  • Caramelized bananas– Caramelized bananas on banana bread mug cakes are for my avid banana lovers. Can’t get enough banana in the mug cake? Add more on top! YOLO.
