Here’s how to make a brownie in a mug which is definitely one of our favorite mug recipes! I love single serving desserts! When I want something a fudgy brownie but don’t want to turn on the oven this peanut butter mug brownie is just perfect! (originally published 8/16)
This brownie mug recipe is quite simple and perfect for a chocolate craving. Sometimes you just want a single serving of yum, not to make a whole pan full.
We love peanut butter inside. Of course you can add other goodies too if you want.
Peanut butter is a must in our house thugh. Yes you can omit it if there’s an allergy, and it is still tastes amazing.
- You don’t have to add peanut butter brownie in a mug, but this addition is delicious!
If you have a sweet tooth but don’t want to make an entire package of brownies or cake this is a great alternative dessert for one!
How do you make microwave treats?
I like this brownie in a mug recipe from Simply Recipes because it is easy and I had everything in my cupboard at home.
I changed a few things and added peanut butter and it came out amazing!
I’m all about easy and ooey gooey desserts so I’ve made this one often because it’s just so easy and hits the spot when I want something sweet.
- I decided to add a dollop of peanut butter in the center but you could also add a few Rollo caramels or leave it all out.
- A “regular” microwave brownie in a mug which is amazing as well.
I’m a peanut butter fanatic so if I am really going to go all in and indulge myself when making a microwave dessert for one I am going to really go for it if you know what I mean.
How to make a brownie in a mug
- Cocoa powder (I use this one)
- Sugar
- Flour
- Salt
- Oil – vegetable or olive oil if that’s all you have
- Vanilla
- Peanut butter (optional, great without it too)
- medium/large microwave safe mug
The reason why you need a mug a bit larger than a standard tea or coffee cup is it may overflow.
Mug cake no egg
Cooking time is short because it is just one (or two) serving really. If you’re looking for a dessert with no eggs necessary, this is the one to make!
- A dollop of whipped cream of vanilla ice cream on top can be added too.
- It’s pretty darn sweet though so I would first try as is. It’s to die for!
If you love this easy brownie in a mug recipe you could put together the dry ingredients in small baggies.
- Then use another “batch” on other nights.
- Write with a sharpie on the bag what wet ingredients you need so it’s quick when you’re ready to make it again.
Seriously, it is so easy that way. Just make a large batch of this brownie in a mug mixture but portioned out into ziplocs so it’s ready when you are.
Looking for another easy mug recipe to try? This one is probably one of our most popular but we have even more below:
Best mug recipe you should try next!
- Chocolate chip cookie in a mug as you can see above and is ooey gooey delish! We love pancake in a mug too.
- Strawberry cake in a mug only requires 2 ingredients. It’s a fat free dessert that’s light and fluffy. A great midnight treat.
- Have you tried to make a Blueberry muffin in a mug yet? My kids love this one.
- Caramel chocolate mug cake is a fun one too using a Rolo in the middle!
Then try our fun pizza in a mug recipe that’s actually SO good!
Can you reheat a mug cake? Well to be honest I have never not finished the entire thing on the first go around.
If I don’t my husband will finish it off but I suppose you could cover with plastic wrap and then microwave for 10 seconds for the next go around.
Make sure you measure flour properly when measuring ingredients.

Donna says
I just made this and it is like a cake you brownie. I cooked mine for 1 1/2 mins since my microwave is only 900 watts.
It tastes just like a peanut butter cake brownie.
The Typical Mom says
So good right?
Moderate Sweet Tooth says
Very tasty but please update your calorie count or serving size (hence my rating). I calculated 672 calories for this serving! Not sure how you got your numbers but they are deceiving.
The Typical Mom says
I don’t calculate that, the recipe card does. It would vary greatly depending on the type of peanut butter you used for sure.
Rachel says
Came here to say the same thing, mine came to 646 calories, with only 90 of those being attributed to peanut butter. I should have checked it myself before eating it but now I know for next time!
LeeAnn says
Just made this, it was amazing. It is now the only one I’ll make
Bay says
It is a really good recipe and it tasted amazing. The only problem for me was the cook time, I think it should have been more of 1 minute and 30 seconds.
Rose says
Ooey gooey goodness! It is so fudgy and satisfying. Perfect for a late night craving! I love that it is eggless so I can like the spoon without worry. Thank you!
Day says
Could I assemble this and then put it in the refrigerator or in the pantry for a couple of days? My boyfriend’s bday is coming up and I’m working so I want him to have a bday treat when he comes home.
Lauren says
Wasn’t my favorite.
Mona says
This is delicious!
Carly Beth Holtzman says
If I want to double or triple the recipe and do it in a microwave safe dish , would the cook time increase 1 min per amount of increased ingredients ( ie: recipe is quadrupled (×4) then cook time is 4 min instead of 1min)?
The Typical Mom says
Haven’t done that but my guess would be yes.
Scarlett Watson says
WOW!! This is so delicious, I really recommend it.
The Typical Mom says
So glad you loved it.
credit cards says
We know how this can work for us.
Vanshika says
Can I use simple cocoa powder as you used the dark one? Do it will have some effect on my brownie.
Vanshika says
Which oil did you use, it’s coconut oil or any other?
Ansleigh says
Mine taste great ,but what can I do if the batter isn’t turning into a brownie?
The Typical Mom says
You could put it in for another 15 sec. if you like a drier consistency.
Kim Cuellar says
I used Trulia and cut it to an 1/8th of a cup and this was awesome!
The Typical Mom says
Awesome idea!
Amy says
I love this! Thanks so much for posting it 🙂
Brandie says
I tried making his with almond flour and it didn’t turn out. Microwaved it for a total of 3 minutes and still the consistency of runny pudding. Stick to all purpose!
Kathryn says
Is that the problem? ? very been trying with almond flour and while I love the taste no mater how long I microwaved or baked it I couldn’t get it to solidify.
The Typical Mom says
I’ve never used almond flour so it is probably a different consistency I would imagine.
Jess says
I used almond flour as well and it was pudding consistency as others have mentioned *maybe recipe could note that regular flour is necessary.* was still sweet and great to kill that sweet tooth!
self says
It’s great with chocolate chips or white chocolate chips too
T says
Plain flour or self rising?
The Typical Mom says
All Purpose
Lauren says
I stopped adding up the calories on this when I got to over 600. Yikes! You could have something much more decadent and satisfying if you’re willing to eat that many calories. Definitely not a little sweet indulgence before bed.
Writergeek says
You can cut so many calories and grams of fat by swapping unsweetened applesauce for the oil. I did that and only used 1/2 the sugar and it still turned out well
Jaime says
Do you think this recipe could be done using a toaster oven rather than a microwave? If so, how long/what temp do you think?
The Typical Mom says
Not sure that would work, could try.
Jerita says
What size mug would you recommend and should it have flat sides, not tapered? I’m super excited to try this! Thanks so much!
The Typical Mom says
I put a link to a mug in the post just now, 12 oz. or larger. Just don’t use a small coffee cup because it will rise and bubble over.
Aimee says
This is the second time I’ve made this, amazing!! Just can’t remember, is a Tablespoon or teaspoon of peanut butter? The ingredients list says 1 t., but the directions say 1 T.
The Typical Mom says
Sorry! Was transitioning to a new recipe plugin and it transferred it weird. It is 1 tbsp., fixed it! So glad you love it too!
Hannah says
Probably the best mug cake I’ve tried so far (and I’ve tried a heaping handful)! Also worked with gluten free flour as a sub for regular flour 😀
Thanks!
The Typical Mom says
SO glad you loved it!!
maramark says
I started making this treat whenever I get chocolate cravings and it’s so easy and yummy! I also love that it is dairy free. Thanks so much for sharing!
The Typical Mom says
OH yeah, so glad!
