Here’s how to make a brownie in a mug which is definitely our favorite mug recipe! I love single serving desserts! When I want something a fudgy brownie but don’t want to turn on the oven this peanut butter treat is just perfect! (affiliate links present)
Brownie in a Mug No Egg Recipe
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.
This is just one baking hack we figured out when I wanted a late night snack but not make an entire batch. A single serving brownie was just what I needed that night. I had made brownies out of cake mix so I knew I could make it other ways than in a square pan, it was time to experiment and figure this out.
Peanut Butter Brownie in a Mug
I didn’t just stop there, I thought adding a bit of hidden peanut butter in the center would be amazing too. That is a must in our house and we always have a few jars in the pantry. 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! My girls will make this as a quick treat for themselves after school and I am guilty of making one late at night when we are watching movies on the weekend. 😉
What ingredients do you need to make a mug brownie?
- Cocoa powder for that classic rich flavor
- Sugar, white gives it sweetness
- All purpose flour is the base of dry ingredients
- Salt, just pinch actually makes the chocolate taste richer
- Oil – vegetable or olive oil if that’s all you have, could use melted butter if necessary
- Vanilla extract will bring out the yum
- Large microwave safe mug so it doesn’t overflow
Boxed Brownie Mix in a Mug
You can do this too!! I mean from scratch is better in our recipe card below but you can combine 2 tbsp brownie mix + 1 tbsp water. Stir and heat on 100% power for 1 minute too. If you have allergies both of these are eggless and dairy free! I know, killer right?? Perfect for my husband who can no longer have either.
Variations
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.
You could use a pinch of chocolate chips instead into the center or 1 tsp of crushed nuts too if you’d rather. I like to keep my baked goods very tender so I don’t like crunchy bites inside myself. I would suggest making it as is directed below and go from there. Compare with and without the add ins and see which is your favorite bites.
Tips for Making the Best Mug Brownie
Make sure you measure flour properly when measuring ingredients for this single serving brownie recipe. What that means is that you need to fluff it, scoop with a spoon when measuring and don’t pack it down. If you do it will become much more dense and not rise properly.
The reason why you need a mug a bit larger than a standard tea or coffee cup is it may overflow. 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!
You can but the best way to do it so that the texture is perfect is to make one serving brownies in a microwave using the mug directions here. You can use boxed batter or our homemade recipe here is even better.
You can actually. I think our homemade recipe below is better but if you want to “bake” an individual brownie just combine 2 tbsp of mix with 1 tbsp of water, mix into a batter and heat for 1 minute. Allow to cool for a few minutes and top with whipped cream!
How do you make microwave treats?
I mean it is really easy, and doesn’t heat up your entire house in the process. This one takes about 10 minutes to prep or so. If you need a simple 2 ingredient microwave treat this is how to make a mug cake with cake mix too.
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 adding the wet ingredients to make the mix into a batter. 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.
How to Make a Fudgy Brownie in a Mug
- Add dry ingredients to mug and stir – use 12 oz. mug or larger.
- Add wet ingredients and stir until mixed.
- Put tbsp. of peanut butter in middle of mix (optional) and push down a bit so it is submerged into brownie batter.
- Microwave for 60 seconds, allow to sit for a few minutes…done!!
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!
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.
Other Mug Desserts You’ll Love
Another one of these treats without eggs is to make our cake mix mug cake below. Fewer ingredients, not as rich and decadent but still satisfies a sweet tooth for sure.
- Strawberry cake in a mug with cake mix only requires 2 ingredients. It’s a fat free dessert that’s light and fluffy. A great midnight treat.
- Chocolate chip cookie in a mug as you can see above and is ooey gooey delish!
- Have you tried to make a Blueberry muffin in a mug yet? My kids love this one.

I love this! Thanks so much for posting it 🙂
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!
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.
I’ve never used almond flour so it is probably a different consistency I would imagine.
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!
It’s great with chocolate chips or white chocolate chips too
Plain flour or self rising?
All Purpose
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.
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
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?
Not sure that would work, could try.
What size mug would you recommend and should it have flat sides, not tapered? I’m super excited to try this! Thanks so much!
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.
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.
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!
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!
SO glad you loved it!!
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!
OH yeah, so glad!
