Brownie in a Mug | Easy + Quick

This Brownie in a Mug recipe is SO GOOD. I’m telling you right now the texture is not like a regular chewy brownie….but it’s not a mushy, rubbery cake texture either (the kind you usually get with recipes like this). Instead, it lies somewhere else in a place I like to call dream town.

I’ve got a feeling that you all will be making this mug brownie this weekend…and it’s all thanks to my friend Claudia. That girl knows what’s up. I have no idea where she got this recipe, but it is PRIME. I was way skeptical at first, but then I tried it and just about died because:

  1. no cake made in the microwave is typically worth my time/the calories
  2. this recipe has no eggs….whaaaaa?
  3. it was super chocolatey and delicious, probably thanks to the copious amounts of whipped cream up on top.

Um, swoon.

Main Ingredients Needed

You’re only 9 simple ingredients away from this delicious single-serving treat. Like many of the people who have tried this brownie in a mug recipe (see the comments) feel free to experiment to make this recipe even more perfect for you! Here’s what you’ll need to make this perfect mug brownie:

  • Flour – this is all the structure we need for this brownie, especially if you keep it in the mug. No eggs here!
  • Brown Sugar – to sweeten. You could also use regular sugar here as well.
  • Cocoa Powder – unsweetened cocoa powder to be exact. To make it chocolatey.
  • Milk – for moisture.
  • Vegetable Oil – you can also melt the same measurement of butter and use that instead. Do not use olive oil, the taste is too pungent for this sweet treat.
  • Salt – to balance out flavors.
  • Vanilla – a good complement to the chocolate.
  • Coffee Extract – optional but it brings out the chocolate flavor even more.
  • Whipped Cream – use storebought or make your own homemade whipped cream for this recipe. Or even top with vanilla ice cream.

Microwave Brownie Pro Tips

To ensure a perfect brownie in a mug every time, I’ve compiled these tips and tricks, just for you!

  • Don’t Overmix. The more you mix, the more gluten will form, the more it will taste like rubber.
  • Don’t Overbake. Again with the rubber thing…..not good when we’re talking about brownies.
  • Adjust Microwave Times. You’re probably going to have to do a little trial and error with your microwave, but I’m sure tummies across this great globe will happily oblige.
  • Toppings. Ice cream and/or whipped cream is best placed on top of such a mug brownie.
  • No Mug Brownie. If you want to not eat your brownie out of the mug and make it look prettier a la Lauren’s Latest, combine the batter together in a small bowl and pour into a greased mug. After it’s baked, loosen up the edges and plop it onto a plate. Add appropriate accouterments as necessary.

    Is it important to use vanilla cause i already mixed the batter and then realised i don’t have any vanilla at home but i have the powder one so can i use it instead?

    I made this bc I was craving brownies so much and I was not disappointed! 😍 This recipe isn’t like other mug recipes at all. The brownies were nice and soft and not dry at all! I will definitely save this recipe! Thank you for saving my night😋

    This recipe is amazing! I’ve made it so many times in the last year. Best mug brownie I’ve ever had! Thanks, Lauren!

    on the Youtube video, it says you don’t have to spray the mug and can just bake with the mug you were mixing in. Also, did you use flavorless oil like canola oil or sunflower oil? that might be the reason, because mine turned out delicious and did not taste like oil at all!

    The brownie is extremely rich and probably for two people. I added a bit more brown sugar and some chocolate chips to get more sweetness. Cooked for 1.5 minutes. My daughter is allergic to eggs, so I saved her some to enjoy tomorrow.

    Love this recipe! The calorie count is pretty crazy, though, so I always just make half and decrease the sugar a little. Problem solved 😋. Thanks for sharing!

    Yummy! I knew it would be tasty when I saw Brown sugar and coffee. 🙂 it’s the little things that turn a regular recipe into an over the top one.

    I’ve never enjoyed any mug cake, but I had a bad brownie craving and didn’t have the energy to full-on bake. After some research and review-reading, I decided to go with your recipe and I am surprised to say that it was absolute heaven! The first mug brownie I’ve not only liked but LOVED! I can’t believe this worked without baking powder! I used chocolate almond milk and olive oil. Unfortunately I didn’t have coffee flavor but it was wonderful nonetheless. Next time I’ll half the recipe though. Even with a sweet tooth, it was a bit much! Thank you for this!!!!!

    This is my favorite mug recipe I’ve ever tried. I’ve probably made this over 20 times, and it always turns out great. If you’re craving a quick and easy chocolate dessert, this is it! I always use dark chocolate cocoa powder and microwave it for a minute and 15 seconds and it makes it rich and fudgy. Thanks so much, Lauren!

    Disappointed, been craving something ooey gooey fudgey for days now; seen pics/read reviews and decided to try. Unfortunately it’s just like all the other microwave mug recipes I’ve tried this week…..drier than the desert, nothing ooey or gooey about it; I even added a spoon of fudge sauce!
    Guess I’ll just have to half bake a pan of brownies.

    I just made this…had a peanut butter cup left over that I sunk into the middle, then leftover whipped cream to top it off…amazing! Thanks for another great (and easy to remember!) recipe, Lauren!

    Just tried this recipe!Very excited!Although the mix seemed to have a putty like texture.It could be the cocoa mix I used though.

    Yeah, Sammie! I used to fix this and had no whipping cream, but I did have ice cream, usually vanilla, that I used in it’s place. It was wonderful. Almond milk in it sounds wonderful, too. I’ll try it.
