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!)

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.

How to Make a Brownie in a Mug

  1. 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).
  2. Microwave the brownie for about 1 minute, or until it’s as set in the center as you’d like. 
  3. Wait a few seconds before diving in, as the brownie in a cup will be piping hot when you first take it out. 
  4. 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

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.

Can this recipe be made in advance?

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 still not found the perfect microwave brownie / lava cake. This tasted great, but the texture was meh – not smooth, sort of “textured”. The top was bubbling with – I’m guessing – the oil, which left me with a pock-marked top. So, while I enjoyed eating it, it’s still not everything I’d like it to be.

    1. Thanks for trying the recipe. It perhaps has to do more with the cooking intensity of your microwave. Bubbling and pock marked just sounds ‘hot’ to me. Maybe try cooking at a lower power level and/or for a bit longer duration. Microwaves are so variable so you may need to play around with the recipe.

    I have to watch my sugar intake so I substituted swerve white and brown sugars and I substituted almond flour for white flour. Sugar free chocolate chips, too! It was delicious! (I microwaved intermittently for about 4-5 minutes.)

    I LOVED this recipe. It turned out amazing! I did have to microwave it for about 3 minutes or so, but I paused it in between and persevered. I usually get really nervous about baking things in the microwave, so I was amazed when this turned out delicious. This brownie was gooey, warm, and everything you’d want! Thank you for sharing this recipe! :)

    1. I’m so glad to hear that you loved the recipe, and that it worked out so well for you! Anytime someone is cooking some thing in the microwave, it definitely takes a bit of trial and error since all microwaves are different, and the exact type of bowl or dish that you use in the microwave also impacts things, but glad everything worked out great for you!

    I made this and it was bubbling in the microwave. I took it out at the one minute mark and it was still liquid. I thought, maybe it’s MY microwave which is the problem, but I put it in for about a minute or so more and it started bubbling and didn’t settle. I think some modifications to the recipe are needed…

    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!!
