One Minute Brownie Mug Cake

Yes, that’s right. I created a brownie mug cake that takes only one minute to make in the microwave. I have to confess, I’m pretty thrilled. This is my favorite mug cake creation yet. And it is still super easy to make.

It’s super chocolatey like a brownie should be. This is more like the cake-type brownies rather than the chewy brownies, but it’s still so good. When it first came out of the oven, the brownie was quite fluffy, like a really good chocolate cake. After a minute or so, the batter turns denser, much more like a brownie because of the minimal amount of flour.

I made two, offered one to the FH. At first he refused. He’s gotten kind of sick of my mug cake creations. I insisted he take a bite and he didn’t regret it. He loved it and kept the brownie for himself.

Because brownies are denser, these don’t rise nearly as much and you don’t need an oversized mug unless you want to double the quantity. A regular mug will do.

There’s one extra step required to create these cakes, but it’s still super easy and clean up is still minimal.

  1. Soooooo good!

  2. Hi! I’m not sure what I’m doing wrong, I made the recipe, I put everything in 1 mug (a bigger one) and then put it in the microwave for 2 mins. It came out really wet and sticky. Do I leave it in for longer? Bacause last time I did that, it came out all rubbery. 🙁

    • This recipe is designed for 2 individual cakes. You should divide the batter into two mugs as stated in the instructions and cook each separately. Adding them all into one will make the batter too dense when it is fully cooked.

  3. Definitely the best mug brownie I’ve made! Is it possible to make this without self-raising flour? That’s what I’ve been using.

  4. loved this recipe!! delicious, easy and overall just simply amazing! 100 % would recomend.
