Sometimes you might need a little more than a single-serve I know, and that would be why I have a number of brownie recipes in our recipe box, such as vanilla, chocolate, and such.

I want to first off say there are two ways to cook these, one way is quick and simple: the microwave. About a minute and it’s done depending on your microwave.

The other way is in the oven. I have used both methods… loving how quickly it cooks in the microwave, but we were a microwave-less household for quite a few years by choice so I often used my oven to make this when I needed a pick-me-up.

This is a great treat at the end of a long day. Maybe top with a little sprinkling of powdered sugar. Or mix up a little frosting. Oh man, vanilla ice cream would be amazing on this, you know, if you can hold on to, eating all the ice cream, which I can not do.

*I am back to having a microwave and this delicious single-serve, just for me, I am not sharing a treat, ready in just 5 minutes.*

In the microwave for 1 minute or until a toothpick comes out clean. If 1 minute doesn’t do it, put it back in for 10 seconds and recheck, repeat until cooked through.

OR if you are using your oven:

Bake in the oven at 350 for 20 minutes or until a toothpick comes out clean.

Delicious! It is light and chocolaty! There is nothing like quick and easy desserts for one to turn your day and night around after a long, hard day.

Be careful because your mug or bowl is going to be hot. These bowl cozies are great to keep you from burning your fingers because you just want to enjoy a sweet treat. Place your microwavable dish inside the bowl cozy and put it in the microwave to heat, grab the cozy instead of the bowl.

  1. I enjoyed it, heavier than I expected but a nice quick dessert. I even made a healthy version for my mom with stevia! Worked well.

  2. The recipe says microwave, but then step 3 says put it in the oven. I would love to make this mug cake- I’m guessing only steps 1 and 2 are required?

  3. Delicious! I did use milk instead of water and added a spoonful of mini chocolate chips. Definitely rich but just what I was looking for!

  4. joking!
    Great and easy to do at home, yummy AND worth it!

  5. AMAZING, I make mug cakes and brownies a lot and this has been the best!

  6. can you substitute the canola oil for anything else? like vegetable oil or something like that?

    1. @olivia, I used coconut oil and it tasted pretty good!

    2. @olivia, Canola Oil and Veggie Oil are interchangeable you can use refined coconut like Mick and it wont give any additional flavor but a non-refined coconut oil but thats based on taste just dont use olive oil lol

    3. @olivia, sorry meant a non-refined coconut oil would give an added flavor and that is based off preference

  7. Really easy and tastes amazing! I think I might be out of coco powder soon because this recipe is so easy and fast to make! No clean up and little to no mess!

  8. Best mug brownie/cake I’ve tried! I added a small pinch of salt and some chocolate chips. Perfect with a scoop of vanilla ice cream, thank you!

  9. This is great! I halved the recipe, used a small pyrex bowl, microwaved one minute and, magic, a wonderful and yummy desert! Thank you!

  10. This was awesome! Love that it’s more fudgy than cakey. I added in 3 dashes of cayenne powder for a little kick. Great with a little ice cream on top!

  11. I really loved this recipe! Turns out we didn’t have any ice cream left in the freezer and I was sad, but googled ‘single serve microwave recipes’ and this one was definitely worth it! Rich, airy, and even fudgy in the middle! Couldn’t’ve made a better recipe myself! Thank you!

  12. This is a good basic recipe. Next time I would add a pinch of salt to balance the sweetness.

  13. I’m a big chocolate lover so I figured I might need to make two, but one was SO chocolaty! It was perfect!
