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 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.

Microwave Brownie Ingredients

For this supremely easy brownie recipe, you’ll need:

  • Granulated sugar
  • Cocoa powder
  • Water
  • Vegetable oil
  • Light brown sugar
  • Vanilla extract
  • Salt 
  • All-purpose flour
  • Chocolate chips

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.

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). Cook 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.

More Microwave Mug Recipes: 

  • Microwave Cinnamon Apple Crumble — Buttery apples are tossed with cinnamon-and-sugar and nutmeg, and the crumble topping is made with cinnamon, brown sugar, and oats. The recipe is pleasantly, but more boldly spiced from the cinnamon and nutmeg.
  • Chocolate-Covered Microwave Peanut Brittle — This flavorful, buttery, and very crunchy peanut brittle is made in the microwave in one bowl in just 9 minutes, without needing a candy thermometer.
  • Chocolate-Covered Microwave Caramels — The recipe works and produces the best-tasting caramels I’ve ever had!  They’re rich, buttery, creamy, sweet, and softly flavored with vanilla.

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!

Yield: 1 to 2 servings
Prep Time 2 minutes
Cook Time 1 minute
Total Time 3 minutes

Ingredients

  • 1/4 cup granulated sugar
  • 3 tablespoons unsweetened natural cocoa powder
  • 3 tablespoons water
  • 2 tablespoons canola or vegetable oil
  • 2 tablespoons light brown sugar, packed
  • 1/2 teaspoon vanilla extract
  • pinch salt, to taste
  • 1/4 cup all-purpose flour
  • 1/3 cup semi-sweet chocolate chips*
  • ice cream or whipped topping, optional for serving

Instructions

  1. To a small microwave-safe bowl, add the granulated sugar, cocoa, water, oil, brown sugar, vanilla, salt, and whisk to combine.
  2. Add the flour and stir until just combined, don’t overmix.
  3. Add the chocolate chips and stir to combine.
  4. Cook on high power in the microwave for about 1 minute, or until the brownie is as set in the center as desired. 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.
  5. Optionally add ice cream or whipped topping and serve immediately. Brownie is best warm and fresh.

Notes

*Double check that your chocolate chips are vegan, if you want this recipe to be 100% vegan.

  1. This looks fudgy and delicious! I have tried other microwave mug cakes with egg and baking powder but sometimes they came out a little “spongy”. It’s good to know the egg isn’t necessary when a craving hits!

  2. Just found your site and am already loving it

  3. Oooh I love small-scale recipe like this, and the fact that it’s only 1 minute? I’m 120% sold!

  4. Love the pictures. The ice cream oozing into the brownie … sigh.

  5. I need to make this for my husband. He is a chocoholic for sure. He would make this a ‘for one’ dessert. HA!

  6. Averie The One Minute Microwave Brownie Looks like fun in a Mug Thank you for the cute idea .

  7. I am so tempted to make this microwave brownie right now! So easy and looks so fudgy! Pinning!

  8. hey girl- this is right up my alley! So yummy!

  9. SO rich and good! Definitely best for two people! Great recipe for intense chocolate lovers!

  10. Oh sweet jesus this is dangerous.

  11. This is tasty. Satisfies my chocolate craving for the day… Maybe even the next two or three!

  12. I make this with 30ml brown sugar, 30ml white, a teaspoon ground flaxseed and a bit of extra water to make it more healthy (it’s the thought that counts…)

  13. Yummy Deliciousness! I used Coconut oil and Gluten Free Flour. I microwaved it for 1:30 . (Used 15 sec increments after first 45 secs.

  14. Just tried this out! Followed the ingredients completely except for the chocolate chips and cocoa (I used less chocolate chips and a very dark cocoa for a little less sweetness). I ended cooking it for a lot longer than 1 minute, I added a lot of additional 20 seconds! (Probably because my microwave isn’t up to snuff!) While this isnt oven baked brownie good, I love that this doesn’t require eggs or milk; it’s a perfect treat for when you dont have anything in the house but are craving something sweet!

  15. Make sure you mix this thoroughly, otherwise, you’ll end up with a goopy mess.

  16. are chocolate chips optional?

  17. 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.

  18. 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. 🤔

  19. 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.

  20. 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
