Ingredients You’ll Need
- Butter: Use unsalted butter, and if you're using salted butter, be sure to reduce the amount of added salt. I also recommend using butter at room temperature, as it melts faster in the microwave. Cold butter takes longer to melt and can make the mug hotter by the time it fully melts.
- All purpose flour: Be sure to fluff your flour before scooping it into the measuring cup to avoid adding too much, which could make the chocolate chip mug cake denser than desired.
- Milk: I add 2 tablespoons of whole milk to add richness and moisture. Any kind of milk will work.
- Brown sugar: I love using dark brown sugar for its rich, molasses-like flavor, which gives the mug cake that classic chocolate chip cookie taste. However, light or golden brown sugar works just as well. If you're a visual learner, check out the video on YouTube for a step-by-step guide!
- Chocolate chips: My go-to brand is Ghirardelli, which I use in all my chocolate chip recipes. I’ve also had great results with the Costco-sized bags and Nestlé chocolate chips.

Serving suggestion
Remove it from the microwave, then sprinkle with more chocolate chips and a pinch of sea salt. Enjoy it warm with a cold glass of milk for the ultimate treat, or top with vanilla ice cream or whipped cream for an extra indulgence!
Recipe tips
- Butter - Use unsalted butter, or reduce the added salt if using salted. I prefer to use room temperature butter as it melts faster without making the mug hot.
- Brown sugar - I love using dark brown sugar for its rich, molasses-like flavor, however, light or golden brown sugar works just as well.
- Enjoy Hot - Like most microwave cakes, it can dry out if eaten later, so we recommend serving it hot for the best texture!
- Finish with salt!

I tried this with substitutions to lower the carbs. I used truvia brown sugar (you use 1/2 the amount of brown sugar called for), sugar free chocolate chips and low fat milk. The "cookie" turned out a little dry, perhaps from the substitutions or the flour I had to use was an ultra cheap generic brand or I may have overcooked it. Next time I will adjust. However, the taste was VERY good. It really satisfied my craving for chocolate chip cookies because a shop recently had a prominent display. Thanks.
Maria Doss
I love the modifications! I'd suggest using a little lesser flour next time to make it more moister:)
Areeya
this was so good! Highly recommend, though I didn't use dark brown sugar!
Maria Doss
So glad that you loved it:)

I thought this was an amazing idea, but I couldn't get mine to work. Do you have any idea what I could have done wrong. also I used GF flour because I have celiacs, could that be why they didn't turn out?
Maria Doss
Hi Elsa, I'm so sorry that you did not have a great outcome. My guess will be the same as well. This recipe is tested for the normal flour and not for gluten free kind. Here is a recipe for gluten free cookie mug cake that I found online - https://www.glutenfreepalate.com/gluten-free-chocolate-chip-mug-cookie-8-ingredients/. Hope it helps:)
Marie Chérie
LOVE IT!! I have been looking for a good mug cookie recipe for FOREVER. Like since the dawn of the microwave. Or at least since college. It’s moist, fluffy, and full of chocolates goodness. Sometimes I like to add a pinch of cinnamon.
Maria Doss
YAY!!! So glad that you loved it, thank you for the kind words:)
Elaine
This is delicious. And also dangerous if you are hoping to maintain a diet. I didn’t have dark brown sugar, only light, but is was still so yummy. I can definitely see how the dark brown sugar would be even better.
Lisa
The first several times I made this recipe were excellent. I don't know what's going wrong now. The past several times I've made it, my result has been a weird goopy boiling mess 😭😭
Maria Doss
Hmm.. that's strange. Are you using a different brand of something? Is it gluten free flour?
Linne
Iets super yummy!!! 😋
Maria Doss
That’s so great to hear, so glad you loved it - Maria ♡
