Microwave Brownie in a Cup

Microwave Brownie in a Cup

I’m really excited to share this recipe for a microwave brownie in a cup! It’s based off my popular recipe for Chocolate Chip Cookie in a Cup, and I have been working hard to develop this delicious, decadent, single serving treat. I’ve used simple ingredients to create a real homemade brownie in the microwave.

Just like my other cookie in a cup recipes, you can mix and microwave this right in a coffee mug. I used a ramekin for these pictures, but either will work wonderfully. Just make sure it is microwave safe.

Brownie in a cup is absolutely amazing with a scoop of vanilla ice cream on top!

Just a note, make sure to follow the steps I have outlined in the recipe, and don’t substitute spreads for butter:0) For more fun ideas, follow me on Pinterest.

  6. I think you have me hooked on this cook it in a cup stuff! Thanks (no, really I mean it even if I have to really exercise now!)

  7. This looks sooo yummy! And I love the microwave desserts in a cup. My hubby always wants the real deal, baked in the oven, and I’m like, “Um… this takes all of two minutes and is easy to clean up. Get over it.”

  8. Holy cow Melissa! This was delicious! I made it last night and am in love. I’m sharing your recipe on my blog today, I linked back to you.

  9. Woowee…these may be about to get me into to some trouble!! YUM!

    Delicious :-)

  11. Ooh, this looks great and dangerously easy!

  12. Oh YES. I love these cup recipes! I’ve made the chocolate chip and peanut butter one countless times. The peanut butter cookie was my valentines treat to my other half! Love these.

  13. I made this tonight and it’s perfect. Exactly what I wanted, and sooo chocolate-y. I replaced the butter with equal amounts coconut oil and it still worked great. Thank you for this recipe!!! I’m going to pin it for future safekeeping too :)

  14. This is such an easy recipe. Yummy, too! I made one with half/half vanilla and almond extract and used butterscotch chips, just as good as the original.^_^ I would not change anything else in the recipe, it wont turn out right.

  15. I just made this right now.
    I put a tad less butter, and I didn’t have any chocolate chunks.. so I broke up a Milky Way in there.
    Was really yummy. Definitely a once in a long while dessert because of all the butter in it, but was
    super easy and fun to make. Thank you for the recipe! ♥
    P.S
    My name is Melissa too. :)

  16. I made a vegan version of it by substituting the butter with vegan margarine and egg yolk for 1/2 flax egg (1/2 tbs ground flax meal with 2 tbs hot water). It was fantastic!!! Tender and full of chocolatey goodness. Not gummy at all..unlike recipes like these that calls for vinegar. No one could tell that it was vegan or that it was made in a microwave!

  17. Mmmm. Thanks for sharing!

    Just curious…what happens if you use the whole egg, not just the yolk?

    • The egg white adds much more lift and will make it more cake like. The egg white can also get rubbery when microwaved, so I try not to use it in my microwave recipes. Thanks for the comment:0)

  18. I made it and it was a little too sugary for me, (25.2 grams) but it was sooooo yummy unlike other mug cakes/ cookies/ brownies! Next time I would use about 1 tbsp & 1 tsp sugar. But other than that it was super delicious!!!!

  19. Hi! I just wanted to say that this recipe is AWESOME! I had tried another popular one that’s all over the internet but it honestly wasnt that good! thank you for sharing this!! :)

  20. This was my first foray into single serving baking and it turned out awesome! I actually did one small substitution though just because I am a chocolate hazelnut fanatic. Our store has lately been selling a chocolate hazelnut spread ala nutella but it’s thicker, less oily and is more akin to the filling of Ferrero Rochers (sssooo yum!). I only used 1 heaping tablespoon of semi sweet chips and added 2 teaspoons of the hazelnut spread. IT was AH-mazing! My boyfriend is also quite grateful as he can now request “a” brownie whenever he wants!

  21. I am so gonna make this when I get home tonight. Been thinking of brownies all day but don’t want a shop bought one. This is just the ticket.

  22. It’s Friday evening and I wanted a treat so I gave this a try.
    It was divine!
    So rich & chocolatey in just a couple of minutes.
    I’ve pinned this and plan on adding it to my favorites.

    BTW, I’ve tried your chocolate chip cookie in a cup and the peanut butter cookie in a cup and this one is by far my favorite!

    Great idea kids love the cookies in a cup yum!

  24. This is sooooo good!

  25. AMAZING!!!
    The BEST mug cakes i have tried!

  26. Michelle says:

    Best microwave cake I have ever had. I have tried a few! Thanks!

  27. My friend and I tried to make these– we have since nicknamed them ‘The Brownie’s From Hell.” Obviously we did something wrong…

  28. RebekahSue says:

    Can I use egg substitutes instead of egg whites? I don’t think it will work but I’m dying for a brownie right now and I don’t have regular eggs :-/ I guess I could just try it….lol. Just wondering?

  29. Adrienne says:

    soooo good!!!!!! i added chopped pecans and caramel bits to mine for a turtle brownie. and i had chocolate chips on hand instead of chunks. i just used around a tablespoon of chips since i added the caramel bits. love this quick n easy recipe!!

  30. mzerikarara says:

    I made it the first time and thought a few tweaks needed to be made. I added just 1 tbsp sugar, and 1 tbsp butter and 1 tspn coconut oil instead of 2 tbsp. I might use self raising flour instead of plain flour next time (hopefully 3rd time lucky) (which I did the first time, turned out great).. The boyfriend liked it last time but thought texture and sweetness was a bit off. Said it was perfect this time and guest finished it this time around too! =)

  31. This is a fantastic recipe! I got a really smooth spongy cake, which was soo much better than one from another recipe. And it only takes 45s! Awesome.

  32. Didn’t have chocolate chips, so I used butterscotch ones instead… DELICIOUS! Excellent microwave recipe!

  33. what flour do i use?

  34. I made this tonight! And it’s absolutely delicious! My only concern is I’m not very sure whether my brownie is cooked haha it turns out a bit crumbly but still delicious! I microwaved it for abt a minute :-)

  35. Replaced the butter w oil, and added a tablespoon of greek yohgurt. Honestly the yummiest thing ever!!! Needs to be eaten still gooey but hot =)

  36. LoverOfPastry says:

    I tried a mug-cake recipe yesterday and was disappointed by the spongy texture, but this… it was wonderful! I used chocolate chips instead and threw in some walnuts, but it was really nice. Thank you!

  37. This looks amazing! I love how you make single serving desserts, just for those special craving :)
    I hope you don’t mind if I use this in a food fight feature?! (photo only and lined back, of course!)

  38. Great recipe! It’s the first Mug Brownie recipe I’ve found which is actually a brownie, and not cake. I cut the sugar back by half (I just prefer less sweet desserts) and the results were delicious.

  39. I just wanna say, I’ve made this recipe about a million times, and it turns out perfectly each one!!! The ONLY thing that I recommend is putting the cocoa powder in before the flour, which makes it a whole lot easier to mix in and disperse evenly (:

  40. if i bake this in a jar with a narrow top, will the brownie still be fine? as in the edges wont be hard and crusty and what not. same with the chocolate chip cookie recipe?

  41. Hi! I was just wondering, how do you keep the brownie from tasting burnt? And how do you know when it’s time to take it out of the microwave so it won’t be overcooked?

    P.S. Your single serving recipes are great for dormers like me! Thank you for sharing them. (:

  42. this was absolutely amazing!! I used 2.5 tablespoons of brown sugar because I didn’t have white sugar. Maybe that’s why it took a bit longer to cook? Its a keeper! Thank you

  43. I just made this and it is SPOT ON. Tastes amazing and super, super easy. Thank you! Perfect for the upcoming cold winter months. :)

  44. This recipe is truly Mmmmmmmm-azing!! I have made other brownie in a cup recipes and they left a lot to be desired. This is absolutely perfect just as it is! I did use margarine instead of butter and chocolate chips instead of chunks being as that’s all I had on hand. The only problem is I can’t get enough and they’re too convenient. Thanks for the recipe!! The kids love them, too!!

  45. add a drop of orange extract, AMAZING

  46. Just made this with a few tweaks… very yummy! Thanks for creating this! Pinned :)

  47. I loved this recipe so much I decided to feature it on my blog! Feel free to come visit. I am just starting out, but can’t wait to add more posts! http://sugarandspicemakeslifenice.blogspot.com/2014/01/25-sweet-treats-that-wont-break-bank.html

  48. The second time I made this I added a half teaspoon of baking soda and it got SO fluffy and amazing! This is an great tweak if you want something fluffy and chocolate flavored! Be sure you make it in a BIG mug because it expands A LOT!

  49. This was amazing! It tastes exactly like a regular brownie and is so moist and delicious. We put walnuts on top. A great treat for Valentine’s Day!

  50. I am totally hooked on these. I too made a couple of changes. I’m not crazy about chunks in brownies, so I substituted a tablespoon of chocolate syrup. Yum! and I also found that the whites can be used on the next brownie with no real change in taste. Thanks for the recipe. I don’t know why my friend told me to back away from the microwave. I’ve only gained three pounds because of these. ;)

  51. Chocoholic says:

    Thinking about putting Nutella in this…can I sub it for cocoa powder or should I add in addition to? How much?

  52. I cannot wait to make this!! Looks so good :)

  53. This is the best brownie in a mug recipe I have come across! Most are way to oily and rich but this one was surprisingly light. I actually halved this recipe and added a really creamy chocolate icing into two small mugs and everyone just raves around it! Thanks for sharing.

  54. I am lactose intolerant, what do you suggest as a substitute for the butter?
    Thanks!

      Hey Lynda! I have a dairy allergy and had a bit of a frown when I saw the warning to not use any substitute spreads. I was craving some Brownie in a Mug, though, so I went on and risked it. I used “Earth Balance” Original ‘buttery’ spread, which is what I use for everything requiring butter, and it made a fantastic brownie. Don’t be afraid to take the risk! I hope this helps.
      -Caroline

  55. I made this today, following the recipe exactly yet the final product was very grainy in texture. Other than the texture, the flavor was nice. Entirely too sweet for me, but otherwise it was the type of chocolate flavor I would expect from a brownie. I may try it again, dropping the sugar down and see how it goes.
