We love making this banana mug cake for one for a quick dessert or breakfast idea. This mug cake recipe is a single serving making it the perfect portion-controlled dessert. Single-serve desserts are such a fun thing to whip up if you’re looking for a portion-controlled recipe or live alone. This banana mug cake tastes just like our Banana Chocolate Chip Muffins, but is made in a mug and serves 1 person! Let’s get started.

Banana Mug Cake Ingredients

First things first, it’s time to assemble your ingredients. Here’s what you need with a few modification suggestions:
  • mashed banana – if you’re not a fan of banana (not sure why you landed on this recipe :P), feel free to use any fruit puree such as pumpkin or applesauce.
  • egg – we have not tried this recipe without eggs, but if you’re willing to give it a shot, you can use a flax egg.
  • butter – option to sub melted coconut oil instead!
  • white whole wheat flour – try using all-purpose flour or gluten-free all-purpose four instead!
  • baking powder – a little goes a long way for one serving.
  • cinnamon – option to omit or use something like chai spice.
  • coconut sugar – feel free to swap for another granulated sugar. We recommend brown sugar.
  • chocolate chips – this recipe is still delish without chocolate chips, but why do that to yourself?!
You’ll want to make sure that you have a medium/large mug or microwave-safe bowl

How to Make a Mug Cake

Making a mug cake is easy and takes less than 5 minutes. First things first, get yourself a medium/large mug or small bowl (yes, bowls work, too!). Make sure that it’s microwave and/or oven safe. Now, let’s get cooking!

1. Mix

First, spray your mug with nonstick cooking spray or rub it with butter or coconut oil. Then, place all ingredients into your mug and use a whisk or fork to mix. I like to start off by mashing my banana on the bottom of the mug. Then, I whisk the egg, and then I add the rest of the ingredients. Option to add more chocolate chips on top for presentation (and more chocolate). Tip: for better presentation and easier cleaning, mix your mug cake in a separate bowl and then transfer into your mug.

2. Cook

We’re sharing 2 cooking options below. The oven method will give you more of a traditional cake/muffin texture, but it takes much longer whereas the microwave cooks much faster, but the results are a bit denser. Oven: Bake at 350ºF for 22-25 minutes. Microwave: Cook on high for 60-90 seconds.

3. Eat

Once your mug cake is fully cooked, it’s time to dig in! We recommend eating IMMEDIATELY ๐Ÿ˜€

I love this. I did this with wheat flour since I didn’t have white and a dab of vanilla. I put sugar free chocolate chips in it, topped it with bananas and pb when done, and gobbled it up. This will def be made again.

I added too many chocolate chips. But the banana cake was delicious. I also added more bananas, and it tasted great.

I love this soooooooooo much! It always comes out just fine. I make this for my family, and I’ll set all the mugs out and basically make an assembly line. ๐Ÿ˜‚ Thanks for this recipe.

Tasted great! I used pumpkin instead of bannana and I only had 2 eggs so I added about a teaspoon of chia and 2 tablespoons of water. Then I ommitied the chocolate chips and added some extra walnut filling we had leftover from walnut bread rolls. (Essentially crushed walnuts, sugar, and cinnamon) I also used some on the top as a streusel.

Hi, do you have the old single serve banana chocolate chip cake recipe archived? I went to my bookmark and was led to this updated recipe. If so, please point me toward it. Thanks!

I gotta ask, is the Big “T” in the recipe tablespoon and the little “t” for teaspoon?

I just made this and I have to say, it was DELICIOUS! I’ve never had good luck with single serve cakes before. I don’t really know why, they just always turned out so-so. But I was so in the mood for a banana cake, and I knew I couldn’t make a whole cake because I’d eat it all (:P), so I decided to try this recipe and I’m so glad I did. It’s already been saved to my all-time favorite recipes ๐Ÿ™‚ Thank you!

Great recipe! I often make it without the chocolate, but pour a little maple syrup over the top when its done, per Diana’s suggestion. I’m pretty crazy with banana ratios – it can get a little soupy if I put in too much banana. Also, I bake at 350 for 25 minutes. Works for my oven. Thanks for the inspiration!
