Chocolate Chip Mug Cake

This single serving microwave chocolate chip mug cake starts with a fluffy brown sugar cake base mixed with chocolate chips. It cooks in just 1 minute and tastes like a chocolate chip cookie that got turned into a cake.

Update! I’ve created a video to go along with this post, showing you just how easy this is to make!

Do you ever have one of those days where it just isn’t your day? And you just want to hide in bed or sit in a dark corner and wait for the day to be over so nothing else goes wrong? I had one of those days yesterday.

In the morning I woke up to rain, which was fine, since we are in a serious drought. But the rain was accompanied by some really strong winds which knocked over one of my precious fruit trees. This was then followed by my shower rod suddenly crashing down into the tub (luckily no one was in the shower at the time). When I stepped outside for 30 seconds to see my tree, I managed to miss a FedEx delivery that needed a signature. (I was seriously only outside for 30 seconds.)

Then, while in a rush cooking a dish, I sliced my finger. It was at this point that I wanted to stop doing anything else and just wait for the day to be over. A few more things happened that I won’t get to into. But yeah, it was definitely not my day. And I kept thinking through the whole day that I really needed some comfort food, aka, this chocolate chip mug cake.

This mug cake really hit the spot. It was warm, fluffy, and reminded me of my childhood. It’s a small, single serving cake, which is perfect since I would have consumed twice as much otherwise. And it comes together in about five minutes.

  • 4 tbsp all purpose flour
  • tbsp brown sugar lightly packed
  • 1/4 tsp baking powder
  • 3 tbsp low fat milk
  • 1/8 tsp vanilla
  • 1/2 tbsp vegetable oil
  • 2 tbsp semisweet chocolate chips


  • Combine all ingredients except chocolate chips into a microwave safe mug. This is a small cake so you can use an 8 oz mug and it should just reach the top when finished cooking. You can also use an oversized mug, but the cake will be lower in the mug. Mix with a small, sturdy whisk until a smooth batter forms and no lumps remain.
  • Stir in half of the chocolate chips. Sprinkle remaining half over surface. Cook in microwave for about 1 minute. Let cool a few minutes before eating.

  1. its probably the best (blank) in a mug ive ever had, its amazing with sugar sprinkled over top

  2. I’ve tried many a horrible mug cake- and by that I mean stomach ache inducing and throwing in the trash. This is the second mug cake recipe I found that is perfect, light, airy, fluffy, chocolatey, and not too sweet. In other words, it hit the spot perfectly. Me and my family of four all shared this, and they’ve tried my other failures and agreed, this was a keeper. A note- I cooked it for about 70 seconds and it was done. Thanks for such a great recipe!!

  3. At first I didn’t think this would work but I’m in heaven it’s so good

  4. Yummy and great this recipe I would use

  5. I subbed the veg oil for olive oil and it turned out just fine. Nice one 🙂

  6. BEST RECIPE for chocolate chip mug cookies I’ve tried so far! The outside is cooked, but the inside is still gooey and the chocolate chips melted a little bit – PERFECT!

  7. Perfect, simple and easily tweakable to taste and a great base recipe for adding other toppings for variety. Thank you so much! 

  8. Good but a bit dry and sticky

  9. I have been making this regularly for the last 5 years and know it by heart. 4 different homes, 4 different kitchens with 4 different microwaves, countless ups and downs in my life, but this recipe has remained constant. (Is that too dramatic for a mug cake? It’s true!) Sometimes I go months in between making it, sometimes it’s ‘one of those days’ every day and I’m making it like once a week… The point is, this recipe is definitely tried and true, and the perfect small way to end both a good or bad day.
    Moist and warm and not too sickly sweet, plus very easy to make, especially compared to other mug cakes with awkward ingredient amounts. It’s the first mug cake I ever tried, and the one I always return to. Just a few notes to anyone reading this, from my experiences, in case they’re helpful: [1] I typically use a non-dairy milk (often vanilla soy), only because that’s what I keep around, and it turns out just as well as the times I use cow’s milk. [2] Adjusting the chocolate chips to taste has never turned out badly for me. When making for others, I used the amount called for, because people love chocolate. I am the rare, weird breed who prefers less (in general), but using a bit less doesn’t make this less flavourful IMHO, because it’s a good base. [3] When using your typical microwave, 60 seconds is the perfect bake time. In my current home, however, I have a tiny 700 watt microwave, which is nearly as low as you can go wattage-wise. After trial and error, I’ve found it takes 85 seconds to get the same fully-cooked-but-not-dry result. [4] Leaving it in the microwave to rest for a few minutes before digging in is worth the wait. You’re not going to want to, because you’ll be able to smell the chocolate goodness, but find the patience in you somehow. It just tastes better when you do (Maybe because it’s cooled enough that you can actually taste it?? No idea). Thank you for this recipe! Sorry for such a wordy comment, but after half a decade of use, I just really appreciate you putting this out there for people like me to enjoy!

    • thank you for taking the time to leave such a detailed comment. I really appreciate it and I love that this recipe has been your constant. Totally not too dramatic in my opinion!

  10. i’ve just made it. turned out perfect. i only sub soy milk and vegan chocolate that i cut it in pieces since i didn’t have chocolate chips.

  11. First ever mug cake. I’ve looked at a ton of recipes but this had everything I wanted. No egg and not a ton of oil. Followed directions with no substitutions. It was delicious. Was large enough it could easily be shared. So easy to put together. I cooked for one minute and it was perfect. Will definitely make again! Thanks for sharing. 

  12. Very dense

    • it shouldn’t be. Make sure you measure out the flour properly. Too much flour can make the cake dense. Also be careful not to cook too long which can also make the cake dense.

  13. The best cake mug recipe I’ve ever had! Most are hit or miss but this one has been perfect every time I’ve made it! Perfect for those lazy days or when you are on your period and you’re craving baked goods but dont have the time, energy or willpower to even then the oven to 350 ? Yum, yum, yum! Thanks for this recipe! ???

  14. I’ve made this 3 times….Its so yummm. Its not just your averagemug muffin…Its beautiful! Thx so much!!?

  15. Delicious! Tempted to make a second 😉

  16. so glad I found this recipe, just gave it a try and it was so easy! Perfect for when you crave something sweet but don’t want to make an entire cake.

  17. This is probably one of the best things i have ever eaten in my life. It is so amazing and super easy to make. I absolutely love it! Thank you for sharing this!!

  18. I love your recipes and trust them 100% and this has been my go to dessert since this recipe came out its so good. Definitely will recommend you to my friends. Your my go to website for any meals. This is my number 1 favorite dessert. Thank you for sharing this with everyone.

  19. I didn’t have any vanilla so I made this with two tablespoon of milk then a tablespoon of French vanilla coffee creamer. And it came out amazing.

  20. I made this with almond milk, dairy free chocolate chips, and no oil. Turned out great!
