Chocolate chip cookie in a mug, missing a scoop.

I know I often share “cheffy” recipes on this site, but I also love simple, kid-friendly recipes, like this warm and gooey chocolate chip cookie in a mug. This delightful “cookie” takes just a few minutes to prepare and a mere 45 seconds to bake in the microwave—and the ingredients are always on hand. What’s more, this recipe recipe makes just a single serving, so I can whip one up for the kids or get my chocolate fix without making a whole batch of chocolate chip cookies (or having temptation in the house!). I use an 8-ounce mug for this recipe; you can use a larger mug, although the cookie won’t be quite as cute, but I don’t recommend going any smaller or the dough won’t have to space to rise.

And if you’re a fan of quick and easy microwave desserts, don’t miss out on my equally delicious brownie in a mug recipe—it’s another instant hit!

Servings: 1 cookie in a mug
Prep Time: 5 Minutes
Cook Time: 1 Minute

  • 2 tablespoons packed dark brown sugar
  • ⅛ teaspoon vanilla extract
  • Pinch salt
  • 1 egg yolk
  • 3 tablespoons all-purpose flour
  • Pinch baking soda
  • 1 heaping tablespoon semisweet chocolate chips


  1. Place the butter in a mug (an 8-ounce mug is the perfect size, but larger will work too) and melt in the microwave for about 30 seconds. Using a small spoon, stir in the brown sugar, vanilla, and salt (don't worry if it looks a little separated). Add the egg yolk and stir until smooth. Stir in the flour and baking soda. Stir in two-thirds of the chocolate chips, and then sprinkle the remaining chips on the top. Microwave on high heat for about 45 seconds, until the dough puffs and looks dry. Remove from the microwave and let cool for a few minutes before eating. (The cookie should be eaten warm; it dries out once cool.)

  • I wanted a sweet treat without a ton of leg work. This fit the bill perfectly. I love that the ingredients are items that I always have on hand. I did cut the brown sugar back to 1 1/2 T as I am trying to cut down. Thanks for another yummy recipe.

  • YUM! Enough said! Perfect for a nice after-dinner indulgence for someone who is too tempted to have a whole batch of cookies around. This will definitely be a go-to when I need to satisfy my sweet tooth!

    • Hi HW, using a whole egg would be too much volume considering the small amounts of the other ingredients.

  • I had tried a few other chocolate chip cookies in a mug recipes, but they came out overcooked and/or lacking flavour. I found this recipe when looking to satisfy an afternoon cookie craving, and it was perfect! It came out almost cake-like, but tasting like a delicious chocolate chip cookie. The best recipe of its kind I have tried yet! Thank you!

  • This was SO yummy! I have a hard time controlling myself around a big batch of chocolate chip cookies, so having built in portion control is perfect for me. I have tried a number of online recipes for cookies in a mug and this one was, by far the best! It was quick and easy to make and had the perfect amount of chocolate. I will be making this over and over!

  • Needing a quick treat tonight and have always been unimpressed with every mug cake recipe I’ve tried so far…until your recipe entered the scene tonight. I whipped it up in a jiffy and me and my hubby enjoyed it so much, getting every last morsel we could scrape up. Just like a soft gooey chocolate chip cookie, but made in only a few seconds…Yum. Thank you for such a great recipe. This one’s a keeper.

  • I’ve made a few of these types of recipes and they always turn out crummy. I thought I’d try this because everything from this site turns out amazing. Well…. It was AMAZING. The only thing that would make it better is a scoop of vanilla ice cream on top.

  • I was so disappointed after making this. Turned out like a dense cake. The cookie was not fully baked. Also after topping it off with chocolate chips, they fell to the bottom after baking. Absolutely disgusting. 0/10 will not make again.

  • I make this often. Hits the spot. Could you come up with a Brownie one? 🙂

    • Glad you like it! I will add a brownie version to my list of recipes to potentially develop. 🙂

    • why? it is awful

      • If you don’t like a recipe & feel you must post, it’s much more helpful to all if you say what you didn’t like about this recipe. “it is awful” is not helpful to anyone.

        I haven’t made this recipe yet but look forward to making it with my granddaughters;-)

  • This is a great recipe when you just feel like a fresh cookie and don’t want to bake three dozen! What I particularly like is the small amount of baking powder, which is much greater in other one cup recipes and makes them taste unpleasant. Your recipes are always foolproof and come out perfectly. I also love your chocolate mousse recipe, which is now a family favorite. Thank you!

  • I am always skeptical of mug microwave desserts, but this was legit really good! With some vanilla ice cream on top it was like a pizookie:) so yummy and i would make again

  • Love this recipe so much that we make it almost every day! So simple and quick to make. Depending on how we’re feeling, we either follow this recipe to a T or make tiny tweaks (for example, adding some raspberries or peanut butter powder) to it here and there to change it up once in a while.

  • Wow! absolutely amazed at how alike this came out in relation to an actual choc chip cookie. My new go to recipe for those days when you just don’t have the time or energy to bake a whole batch of cookies.

  • Oh my goodness!
    I used a whole egg because I am too lazy to separate them, added more chocolate chips and sprinkled salt on top.
    gtg, my second one today is ready

  • This is delicious! Tasted like a warm chocolate chip cookie! So easy to make, which is a bad thing since I loved it so much!! But nice to make when I need that sweet fix! Thanks!

  • This is the best mug cake I have tried to date and I have tried quite a few. It’s somewhat cake like, but flavor and warm, gooey chocolate chips reminded me of a cookie. Thanks for giving me a quick and fun way to satisfy a sugar craving.

  • Excited to try, but I have almost every night your choc chip cookies. Took your advice to make balls and freeze. Take one ( or 2..ha) out before dinner to defrost then back after dinner. Perfect treat and you or forced to eat only 1 ( or 2 😋)

    • Hmm I am digging this idea. I’ll have to see if I have the self control to only pull out one or two to bake up occasionally… 🙂

  • Another positive review! This is delicious. It’s a cakey cookie recipe, but very tasty. For convenience, I used a pyrex measuring cup. I also added more chocolate chips (cause it’s what I do) and it still baked perfectly. We are going on a sailing vacation with the grandchildren, and we can easily make this on the boat! Thank you!!!!!!!!!!

  • can this be made using a ramekin in the oven for those who don’t have a microwave? Suppose that defeats the purpose of quick no-oven recipe but still would be great for single serving kids activity!

    • It should as long as the ramekin is large enough (it should hold at least 8 ounces). Not sure what the bake time will be so keep a close eye on it. Hope you enjoy!

  • Easy enough to make. Good serving for one. Not too much like a cookie. Not fond of how it “baked” in the microwave. Did eat it. Wouldn’t make it again. Not good enough to spend my calories on.

  • Can I bake it instead of using a microwave? Note- I love your recipes! Thank you

    • Hi Winne, I assume you could, but I wouldn’t use a mug (an 8-ounce ramekin should work). I don’t know how long it will take to bake though, so you’ll need to keep a close eye on it. Please LMK how it turns out if you try it!

  • When I saw this recipe in my inbox this morning, I knew my 17 year old daughter would love it. I printed the recipe for her and she immediately made it. Once she finished eating it, she said “This is a 10 out of 10 for sure!” We agreed that we will have to make one for everyone after dinner because it was so delicious and easy to make. Thanks for another yummy recipe that the whole family will enjoy!

  • OMG! Jenn, I don’t know whether to bless you or curse you for this recipe…SO EASY, SO GOOD! Would vanilla ice cream really kick it up a notch? Also, can I use a small whisk instead of a spoon? This will be my go to on many occasions.

    • Ha! Yes on the ice cream, and you can use anything you like to stir it. 🙂

  • I have tried lots of the mug cookie/cake/muffin recipes. This is honestly the first one that tastes like something I’d intentionally eat, not just out of desperation. 😆 No weird aftertaste or texture. Maybe the magic is in the egg yolk. I even made one without the chocolate chips and added a bit of cinnamon and it was still delicious. I can always trust your recipes!

  • This was SO good! And easy. And I’ll make it again soon! Exactly the treat if you don’t want to make a huge batch of cookies but want all the delicious flavor. I may undercook it ten seconds next time to see what a more cookie dough kind of mug cookie tastes like. 🙂

  • If I wanted to make two of these, could I use a whole egg, beaten, instead of two yolks? I never know what to do with egg whites left over. Don’t make meringues. Might try with other flours and less sugar too,.

    • Sure, Amanda, that should work. Enjoy!

  • JUST what we needed. After a nice meal (your recipes again) we wanted dessert and this was just perfect. No chance of overeating. I loved this and will be making more of these instead of baking a batch of cookies or a cake that always manage to get eaten. What a lovely little treat!!

  • I’ve made so many of your recipes that in my house people know when it’s a “Miss Jenn Recipe”, it’s going to be good 😂. Made this for my 5 y/o daughter for her treat this evening in a pretty china mug and she was very impressed! Love how the ordering of the ingredients came together really well! Thank you for another great recipe!!! Can’t wait for your new cookbook!

  • I confess: I haven’t always trusted the mug foods. They just seemed too simple to be any good. So I never tried them…until today..because you make anything good. This is a great pick-me-up for mid-afternoon. Thank you for proving me wrong! 😊
    *extra information: I used white sugar because I didn’t have brown and I used 1 tablespoon (total) of mini chocolate chips for the same reason. Lastly, I used King Arthur all purpose gluten free flour because I don’t use regular flour.

  • My cookie turned out perfectly and I’d like to make this again with my granddaughters. Can I microwave two mugs at a time and if so how would I adjust the time?

    • Hi Millie, Glad it came out well! For 2 of them, you could up the time in the microwave to 1 minute and see if that’s enough. Or to take any guesswork out of it, you could just microwave them separately.

      • Let each of the girls mix up their own cup,; they wanted to microwave separately and they both came out perfect. I love that they could do their own and yet share the experience – Thank you 🙂

  • This sounds absolutely fabulous. I was wondering if there are metric conversions for it?
    Thanks, Maureen

    • Hi Maureen, I just added them. Hope you enjoy if you make it! 🙂

  • I made the chocolate cookie in a mug as a surprise for my wife. It was a huge hit. She raved about it. Going to make it for my grand daughter when we go to visit. So easy to make and so yummy. Thanks for this.

    • After a long (short) week, I needed a portion controlled cookie. Very good!

  • This was fun n so tasty! Only wish I had vanilla ice cream!

  • I couldn’t resist making this as soon as your newsletter popped into my inbox this morning — it’s SO easy and yummy. I made a second one for my teenage son. He devoured it and then asked for another…so much for the single serving!

  • I made this today with my seven -year old grandson. It didn’t look quite done after 45 seconds so we added about 20 more seconds but then it was a bit dry and hard but my grandson loved it and asked me to send the recipe to his mom. Also, I used light brown sugar since I didn’t have the dark brown so that probably was part of the reason it didn’t look done after 45 seconds. But, it was enjoyed by him and I was “allowed” a taste. It was a great activity for “Camp Grammy” and I’m sure will be a regular quick dessert.

  • This was YUMMY! I work from home, this came through on the email of the day and I took a little break to try it. This was quick, delicious, super easy and completely worth the calories! Thanks so much!

  • Loved that this recipe was so simple yet delicious! Thank you Jenn!

  • I made it G.F. by exchanging 2tbsp almond flour and 1 tbsp oatmeal for the flour. delicious

    • Holy cow…so easy…so perfect. Another solid recipe from Jenn for the win!

  • I love the idea of these, especially as a Home Ec teacher, a quick recipe like this can be fun when you have a spare 10 minutes! I’d try this again with half as much sugar. The texture and flavour was great but just a bit sweet for me x
