Table of Contents
I was tempted to call this recipe “One-Minute Microwave Brownie For One,” but if you have some restraint and self-control you can split it with someone and it becomes For Two.
I make this mug brownie for my daughter and I when a craving for chocolate in the baked and gooey form comes over us and handfuls of chocolate chips or nibbles of chocolate bars from the pantry just won’t do.
There’s something about warm, molten chocolate that is just so satisfying, and when you need your chocolate fix in this fashion and have no patience to wait, this microwave brownie is the recipe to make.
It’s extremely easy, made in one small bowl without a mixer, and your brownie is ready in one minute, give or take, depending on your microwave’s strength.
I just saw this recipe, had all of the stuff, so I made it. OMG – it is so good!!! And used Cool whip as I didn’t have any ice cream. Will use that next time. Thank you for those of us who are choco-holics – this is just what is called for when you have a chocolate attack.

This microwave chocolate brownie in a mug is egg-free. That’s great for those of us who like our brownies more along the lines of raw and gooey rather than well cooked.
There’s no baking powder or baking soda in this easy mug brownie recipe, which is great for a few reasons. The texture stays denser and more brownie-like rather than cakey.
And if you’ve ever ‘baked’ anything in the microwave, you know that things have a tendency to rise and overflow with no warning. That’s less likely to happen with this recipe sans baking powder or soda.
The texture isn’t as densely chewy as typical baked brownies, but ‘beggars can’t be choosers’ is what comes to mind with this recipe. It’s a mug brownie ready in one minute, it’s warm, decadent, and studded with chocolate chips throughout. Enough said.
Ingredients for a Microwave Brownie

- Light brown sugar
- Vanilla extract
- Salt
- All-purpose flour
- Chocolate chips
Note: Scroll down to the recipe card section of the post for the ingredients with amounts included and for more complete directions.
How to Make a Brownie in a Mug
- To make a gooey brownie in a mug, simply add all the mug brownie ingredients into a large mug or bowl and stir to combine, making sure not to overmix (otherwise you’ll activate the gluten in the flour and your brownie may become tough).
- Microwave the brownie for about 1 minute, or until it’s as set in the center as you’d like.
- Wait a few seconds before diving in, as the brownie in a cup will be piping hot when you first take it out.
- I like to top my microwave mug brownie with a scoop of ice cream or a dollop of whipped cream, but that’s optional.
I know this post is almost 3 years old but I just have to comment and tell you that I have lost count of how many times I’ve made this. It’s gotten me through 2 pregnancies 😂 it’s delicious, easy, I always have the ingredients on hand and it never disappoints. There’s a lot of microwave brownie/cake posts on the internet but when I finally discovered this one, there was no looking back.

Recipe FAQs
I haven’t tried making this microwave brownie recipe with gluten-free flour, but I’ve had readers say it worked out for them! You may need to play around with this recipe a bit to figure out what works for you. Please leave me a comment if you find a way to make this gluten-free that you like!
Yes, but they add extra flavor and make the brownie super gooey! You can also try using peanut butter or butterscotch chips, just saying.
Sure, why not! Pretty much any baking chip will work, as would chopped nuts or dried fruit. You can add up to 1/3 cup of your favorite mix-ins.
All microwaves, bowls, ingredients, and preferences for doneness vary, so you will need to experiment with how long it takes to cook given your variables. I recommend stopping to check at the 45-second mark and going from there in 15-second bursts as necessary.
This single serve brownie recipe can be made in either a large coffee mug or a bowl. Make sure to choose something that’s large enough as you don’t want the brownie to overflow as it cooks. Also, it goes without saying that you should use a microwave-safe mug or bowl for this recipe.
No. Since this is a microwave dessert, I recommend enjoying the brownie right away. It doesn’t keep as well at room temperature like regular brownies do.

This was the greatest recipe I’ve tried so far with microwaved brownies! Every recipe I’ve tried always came out WAY too fudgy. This one had a perfect balance. Thank you so much for the recipe!

I’ve tried making this recipe several times and I think I’ve finally solved it. I’ve tried mugs and bowls (mugs work better) with varying but similar results – burnt top/sides, raw middle. So today, as I’m giving it one last shot, I decided to add a 1/4 tsp baking soda and a small egg to the batter. And voilà, a perfect mug brownie!!
Thanks for persevering with this one and glad it came out perfectly finally!
This was good but almost too sweet/rich for me. I like sweets a lot so this is saying something 😂
Good, but…. a *little bit* disappointing. I ended up microwaving it for over 13 minutes, in little time chunks, and it was still kind of goopy, although burnt. I was also stirring it every now and then in the microwave. I’m sure this is a me problem, though, and although it was rich, it still provided a delicious snack and cured my chocolate craving. For this reason I’m still giving this recipe 5 stars.

Thanks for giving this 5 stars despite it being a little difficult for you. Microwave-able desserts are a tricky area because everyone’s machine + the mug you cook it in vary, and therefore results and overall experience can vary, by a lot sometimes. Thanks for trying the recipe!

Thanks for the 5 star review and I’m glad this has been an invaluable recipe for you – including two pregnancies! It’s actually older than 3 years (I reposted it 3 years ago with updated info, but it originated in 2017 actually!)
This was absolutely delicious. I used butter instead of oil and a chopped chocolate bar instead of chips. Oh and I used black cocoa bc that’s all I had. But this was everything I was hoping for in a mug brownie!!

Followed exactly. Cooked for 5 minutes so far and all it did was boil in my microwave.
Followed the recipe exactly and I’ve cooked the brownie 4 times now for 1 minute each. It’s still super gooey. Everyone else in the comments seem to have had success but I can’t seem to get it to work
Then I suggest simply cooking it longer. Not all microwaves have the same strength and power.
I had the same trouble. One minute is simply not enough for this amount of batter in a bowl. If you used a flat baking dish, one minute may work.
One minute is a guideline, but all microwaves very dramatically. And some of them are real scorchers and some aren’t. Of course cook it until it’s done based on your microwave.
I just saw this recipe, had all of the stuff, so I made it. OMG – it is so good!!! And used Cool whip as I didn’t have any ice cream. Will use that next time. Thank you for those of us who are choco-holics – this is just what is called for when you have a chocolate attack.

Thanks for the 5 star review and I am glad this was OMG good for you and that it helped you out with your chocolate attack :)
No way this comes out correct! After 3 minutes, all it resembles is molten lava. It never set up.
Can this be made with olive oil?
Thanks!
Yes but it will have a more pronounced flavor and taste than using a more neutral oil.
great
Needed chocolate fix around 9pm. Tried this quick and easy recipe and loved it. Satisfied my chocolate craving.thank you!
