Introduction: Banana Bread Mug Cake Recipe

About: I work at instructables by day, and turn into a stitch witch by night. follow me on instagram @jessyratfink to see what i'm working on! ^_^

I love banana bread, so when I saw a mug cake version of it, I knew I needed to give it a go.

This banana bread mug cake cooks in under two minutes in the microwave and tastes very similar to traditional banana bread. It's a little sweeter and a bit denser, but it will definitely hit the spot if you're craving banana bread.

This mug cake is awesome with whipped cream or ice cream, too! I had a little Cool Whip left over from other recipes and put some of that on top. :)

Step 1: Ingredients + Mug & Microwave Info

  • 1 tablespoon butter, melted OR 1 tablespoon of cooking oil
  • 1 egg, beaten
  • 1 tablespoon milk (can use regular, soy or nut)
  • 1 very ripe banana, mashed
  • 3 tablespoons of all purpose flour (make sure to scoop the flour out of the bag with a measuring spoon so you get enough!)
  • 3 tablespoons brown sugar, lightly packed
  • 1/2 teaspoon baking powder

You need a 12 oz+ mug for this! I'm using a 14 oz mug. Any smaller than 12 oz and you risk running over the edges. Plus, it's really hard to mix everything in a teeny mug.

The microwave I'm using is 1000 watts.

Try not to deviate from the ingredients above - I can't guarantee this will work if you substitute all the things. ;)

Step 2: Melt the Butter and Add the Egg and Milk

If you're using butter, throw it in the mug and pop it into the microwave for 15-20 seconds to melt.

If the mug is extremely hot after this, let it cool down until you can easily hold it. This will keep you from scrambling the eggs.

Add the milk first and then the eggs and mix everything together well with a fork. :)

Step 3: Add the Mashed Banana

Add the mashed banana into the mug and stir everything with the fork - you can be pretty rough with it to make sure it's all mixed well.

Step 4: Add the Dry Ingredients

Add the flour, brown sugar and baking powder.

Mix this well with the fork again - try to break up any clumps! Just don't mix it for too long or you'll have a chewy cake.

Step 5: Cooking

This cake will take between 1 and 2 minutes in the microwave.

Here's how I recommend cooking it:

  1. Cook the mug cake in the microwave for 1 minute at full power. Stand near the microwave to babysit it - if it starts to rise above the rim of the mug, open the door and let it fall. Once it's fallen, close the door and begin cooking again.
  2. After the first minute, check the top. Is is still wet? If so, do an additional 30 seconds.
  3. Continue cooking at 15 second increments if the top still looks wet after the initial minute and thirty seconds.

When it's done, the cake will look dry on top and be firm to the touch. It should pull away from the edges of the mug, too!

Made it. It was delicious :)

I putted some blueberries and chocolate topping ;)

But didn't have baking powder so it was not as pretty as yours, but I ate it and it was great.

Thank you

I've often heard of banana bread but had never tried it, until now. Used your recipe and it turned out great, it's definitely a keeper.

Could this be done with a longer baking time in the oven? I don't own a microwave oven and don't intend to acquire one, but the recipe sounds interesting.

Oooh, joins the rank of the chocolate cake in a mug gallery! Bravo! Now I know what ELSE to do with those over ripe bananas!

Genius!

Just made two cups for me and my wife and wow! This is so good, but requires quite a bit of stamina to finish due to its richness. Next time we will share a single cup.

A single cup is much more romantic anyway.

Oh yeah, for sure! I tend to eat one and then lie down on the couch for a while. But it's so good I can't help myself. :D

I think I need "evil baking genius" to be added as a skill on my LinkedIn page

My thoughts exactly. I can't wait to try this.

Have you tried it adding nuts to make it a banana nut cake?? Does it work well?

1 reply

I have not! I bet if you did a couple tablespoons of finely chopped nuts it would work.

Sadly, no nuts allowed in my house or I'd try it out!

That looks TASTY! Gonna download this and try it!

Did I miss something, because the popularity of mug cakes has exploded in the last month!

Ha! I think it just comes in waves sometimes. You might be about to see a lot more of these from me if I find good ones. :D
