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. It was really good but as it says in the recipe it is really small so if you have a bigger mug and want to have more cake just double the recipe.

    • We don’t recommend doubling the recipe in one mug – instead, we recommend making two separate mug cakes. That way, they cook evenly and have the right texture.

  2. Just made my first mug cake using this recipe. Choose it because it didn’t need an egg. Drizzled caramel on top but made it a bit too rich. Will cut choc chips back a bit next time. Will also try swirling strawberry jam into batter instead of chips.

  3. Can I use self rising flour and omit the baking powder?

    • Not sure how that will work – you need the same ratio of flour to baking powder that is in the recipe. It’s hard to know if 4 tablespoons of self-rising flour will have that correct amount baking powder. If it’s less, your cake won’t puff up as much (or at all). If you give it a try please let us know how it works for you!

  4. Students did not like this recipe 

    • Can you share more about what didn’t work – would love to help troubleshoot! The recipe has been made countless times by lots of readers with success.

  5. OMG! I Just Made It 2day and was AMAZING. Definitely Recommend This For Every Age But A Tip Don’t Put A Lot Of Chocolate Chips??

  6. Finally found a mug cake that tastes good. Would be phenomenal with caramel drizzled on top!

  7. Bookmarked! This recipe is delicious! I used a 16 oz mug and doubled everything. Microwaved for about 3 mins (I’m paranoid about undercooking anything) and I definitely could’ve done with about 30 seconds less. It was a bit firm and overcooked, but that was totally my own fault. I plan on trying this again tomorrow night with a bit less microwave time. Perfect pick-me-up for after my son goes to bed and I get a bit of Me Time!! Also goes amazing with a cup of coffee.

  8. Amazing mug cake very delicious

  9. I’m actually shocked. It’s AMAZING! Tastes just like a soft chocolate chip cookie! I added some sea salt on top of the second one I made and I love it soooo much! Great recipe!

  10. Can I substitute vegetable oil for unsalted butter and if so what would be the quantity? Love your recipes!

  11. Very tasty and very simple to make. The recipe needs a sprinkle of salt. 

  12. This has been my go-to chocolate chip mug cake recipe for a couple years now and it always hits the spot 🙂 Thank you, Jennifer!

  13. Cake tastes delicious. It did need some extra time in microwave.
