Banana Mug Cake

I love banana bread, but when I develop a craving for it, it takes a while to satisfy. I have to mash some bananas, bake for an hour, let it cool, etc. But not anymore.

Banana cake is possible in just a few minutes.

Someone requested I try making this cake, but I didn’t get a chance to try creating it until now, after being given some lovely organic bananas from Organics Unlimited . This cake came out light and fluffy with a flavor of bananas and cinnamon.

When I added egg yolk to the batter, it turned the cake quite yellow. I worried it would affect the taste, but it didn’t taste too eggy.

I even lightened the cake a little by replacing by eliminating the oil with some nonfat yogurt and nonfat milk. Though I haven’t figured out how to make it as light as some of the other mug cakes I’ve altered.

Like all the other mug cakes I’ve made, this one was easy to make.

A little more information about the bananas. Organics Unlimited is a woman-owned company that grows organic bananas for their brand GROW. The bananas are grown in Mexico and a portion of proceeds is donated to their GROW fund which helps fund health, dental and educational programs for Organics Unlimited workers and their families. You can read all about the young company on their website. I didn’t detect too much of a difference in taste for the bananas, but I do love that they are organic.

  1. I agree, banana bread usually takes some planning! First, you must have very ripe bananas. And then the mashing and baking. Also, some recipes say to wrap the bread in foil and let it stand for a day for the flavors to develop! This mug cake looks tasty.

    • It’s not quite banana bread, since it’s a cake, but it’s still yummy and satisfies my banana bread cravings. =) I try to keep some really ripe bananas in the freezer at all times so I don’t have to wait for new bananas to ripen.

  2. i love how easy your mug cake recipes are! i want to try this but need to buy that Greek yogurt though.

    haha, when I first glanced at your post, i thought it said, “Banana SLUG Cake”!

    • hehe, bananas are kind of slug looking after they turn too ripe. I’m sure there is a version that can be made without greek yogurt but I’ve been trying to healthify some recipes, so I played around with one using some greek yogurt. Though if you do have greek yogurt, you can make the greek yogurt chocolate cake or the greek yogurt chocolate cookies. Both really good! Or the greek yogurt fudgy Nutella mug cake. All of them used the greek yogurt and I was completely able to eliminate eggs and veg oil so I cut out hundreds of calories and most of the fat.

  3. I was just thinking about making a banana cake when this popped into my google reader! 🙂 Thank you!

  4. Delicious! I didn’t use the yoghurt at all, added an extra tblspn of lite milk instead. Couldn’t eat all of it, very filling.

  5. i just tried it and it tastes so much like banana bread. I didnt have plain greek yogurt so i uses vanana(vanilla/banana).
    love your much cake recipes

  6. I was craving, and have been wanting to try your mug cake for a while now. Unfortunately I didn’t have yoghurt or eggs at the ready, so I substituted the yoghurt with a tbsp of milk like someone commented before and left out the egg. I’m amazed it still got the job done, and is very yummy! Thank you so much for sharing!!

    • I’ve actually been making a lot of them without egg now. I like them better without the egg too and it’s so much easier.

  7. To make mug cakes do we have to grease the inside of our mugs with oil first? I’m a beginner and it’s my first time trying to make one. 🙂

    • No you don’t need to spray. The cake won’t just pop out of the mug after, but if you soak it after you eat it, it should be pretty easy to clean.

  8. I was making banana loaf for tomorrow and got cravings, so gave this a go. But, sadly, after six or seven minutes in the microwave, it was still uncooked. Beats me!

  9. My banana loaf failed as well! Different oven, so the common factor was: me. 🙂

  10. I’d just bought new. Or so I thought until the memory of your comment made me check. Turns out it was the baking soda and cream of tartar that was new, d’oh! Thank you.

  11. I love these Mug cake thing they are so Good! In this one I didn’t use yogurt, I hate yogurt I used vanilla to make it amazing! It was super yummy! Thx:)
