I love single serving desserts! When I want something sweet at night and don’t want to turn on the oven this peanut butter brownie in a mug recipe is just perfect! It is quite simple and perfect for a late night treat and you can really fool around with it and add other goodies too if you want. We love the added peanut butter but if you have an allergy in your house you can omit it and it is still delicious! Here’s how to make a brownie in a mug which is definitely one of our favorite mug recipes! (originally published 8/16)
You don’t have to add peanut butter to make a 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!
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 and just make 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.
This is what you’ll need and a video showing how to make a brownie in a mug

If you love this easy brownie in a mug recipe you could put together the dry ingredients in small baggies to use on other nights and write with a sharpie on the bag what wet ingredients you need so it’s quick!!
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.

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.
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!
