One-Minute Microwave Brownie — 🍫 When chocolate cravings strike, make this EASY brownie recipe in one bowl, without a mixer, and it’s ready in ONE MINUTE!! Rich, FUDGY, decadent, and accidentally vegan!! (no dairy, no butter, no eggs!)
Easy Microwave Mug Brownie Recipe
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 it 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 have a 2013 recipe for a Fudgy Chocolate Brownie Microwave Mug Cake, and while that recipe is great, there’s an egg involved.
This new mug brownie recipe is egg-free (and dairy-free), which makes it accidentally vegan. That’s great for those of us who like our brownies more along the lines of raw and gooey rather than well cooked.
Not that I haven’t eaten my fair share of raw eggs in cake batter, brownie batter, and cookie dough and am still alive to tell wonderful tales all about those batters and doughs, but I digress.
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 brownie ready in one minute, it’s warm, decadent, and studded with chocolate chips throughout. Enough said.
Ingredients for a Microwave Brownie
For this supremely easy single serve brownie recipe, you’ll need:
- Granulated sugar
- Cocoa powder
- Water
- Vegetable oil
- 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.
No really, that’s it! Just make sure your chocolate chips are vegan if you’re strict about that kind of thing. Most semi-sweet chocolate chips are naturally vegan, but it doesn’t hurt to double check!
I also like to top my microwave mug brownie with a scoop of ice cream or a dollop of whipped cream, but that’s optional.
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.
Can I Make This With Gluten-Free Flour?
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!
Can I Omit the Chocolate Chips?
Yes, but they add extra flavor and make the brownie super gooey! You can also try using peanut butter or butterscotch chips, just saying.
Can I Add Other Mix-Ins?
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.
How Long Should I Cook a Microwave Brownie?
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.
What Size Mug Should I Use?
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.
Tips for Making a Microwave Mug Brownie
- I stuck to chocolate chips, but you’re welcome to use any baking chip(s) you’d like in this mug brownie recipe.
- 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.
- I like to mix all of the ingredients together in the bowl or mug I plan on microwaving the brownie in. That way, I don’t had to dirty any extra dishes.

Sound great, but too many ingredients for a mug brownie. I like fast and simple. Might as well make a whole pan!
There’s basically two sugars, oil and water, flour and cocoa.
It’s really not that many things IMO in order to make something that tastes like a brownie in *one minute* but we all have our opinions what constitutes too much.
Can you cook in oven instead of microwave?
Probably yes.
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!

Hi Avery:
This looks amazing. Can i use whole wheat pastry or oat flour?
I have only used AP flour so can’t say how the others will work.
Made this tonight for small dinner party, added rasberries on the side, main was your slow cooked lamb shanks, I am soooo happy, I’m not a very good cook, but the feedback from the dinner quests was 10/10 for both courses, thanks so much, you are a gem for putting these on your web site. Viv
Thanks for the 5 star review and glad you enjoyed this

Glad this is your favorite microwave brownie!
Made this. Super gooey and good! Used Hershey’s syrup instead of chocolate chips, had to cook for 1 min 30 sec. honestly, I don’t recommend trying to eat the whole thing without ice cream, it’s almost too much without something to break it up.
I dont have chocolate chips currently/cause my mom hides them, but I have peanut butter; so maybe i could put a tablespoon in the center. 🤔
So yummy! I made this tonight and halved it for myself. Perfect size. I followed the recipe exact and it was great. I think I will try peanut butter chips instead of chocolate chips next time to change up the flavor.
Thanks for the five star review and I’m glad it was perfect! PB chips sound great too.
