Recipe

Chocolate Chip Cookie in a Mug
Author:Ingredients
- 1 tablespoon oil , such as sunflower oil, vegetable oil, canola oil. mild olive oil (or 1 tablespoon of drippy nut butter for an oil-free cookie)
- 1 tablespoon water
- ¼ teaspoon vanilla extract
- 2 teaspoons ground flaxseed , IT MUST BE GROUND NOT WHOLE. If you don't have ground flax you can omit it. It still works but the texture doesn't get so cookie-like.
- ⅛ teaspoon fine sea salt
- 2 tablespoons cane sugar or white sugar
- 4 tablespoons all purpose flour (in the UK use plain flour). For gluten-free, use certified gluten-free oat flour and increase the amount to 6 tablespoons.
- ⅛ teaspoon baking soda (bicarbonate of soda in the UK)
- 2 tablespoons dairy free chocolate chips
INSTRUCTIONS
PLEASE SEE THE RECIPE NOTES BEFORE YOU MAKE A START
- To a mug, add the oil, water, vanilla, ground flax, salt, and sugar. Stir them up, then add the flour and baking soda. Stir together until everything is combined. Don't over-mix it. Then add the chocolate chips and stir gently again. If you used nut butter instead of oil, you might find that it's a bit too stiff to stir. If so add a teaspoon or 2 of water to loosen it up slightly.
- Smooth the top out a little then place the mug in a microwave and cook on high for 45 seconds. Leave to stand for 30 seconds to 1 minute before eating for optimum cookie texture.

out of the whole world i cant believe this is popular If i could i would throw this recipe in the trash. No one should be eating this including you
you are telling me right now that people love eating a bland and bad tasting cookie in a mug
hope you think of deleting this wannabe cookie dough trash
Loree says
Yum! Easy and tasty. I doubled the recipe for 2 mugs. We liked it as it was but will reduce the Sugar by half the amount to make it a little less sweet to our taste. The batter seemed a little greasy so I added an additional tablespoon full of flour to get to consistency I wanted. 40 seconds seemed a bit undercooked so I cooked for 30 Sec more. I also added a sprinkle of cinnamon to my batter, gave it an added aroma to the finished cookie. To make it a La mode, we added a small scoop of vegan ice cream: Trader Joe’s, Okey-Dokey, nondairy, oat milk frozen dessert. Delicious
Mackenzie says
I subbed the almond flour for 2 tsp ground flax and it worked great. I also added some shredded coconut and a sprinkle of sea salt on top - deelish!
Alexa says
Sooo good! Easy to follow instructions. It was a perfect serving size - definitely hit the spot!
Tracie R says
This is SO GOOD! It's summer, I don't want to turn the oven on, I don't even want to take time to do a small batch of air fryer cookies -- I just want a chocolate chip cookie FAST. This hit the spot! The hardest part was waiting 30+ seconds to not burn my mouth on the finished cookie :)
Ada Stones says
I have made this recipe easily 50+ times since I discovered it, and it’s honestly what got me through my second pregnancy! So good-I even double the recipe and put it in a bowl because a mug is not enough
Melanie McDonald says
Love that! So pleased you're enjoying it. There's a new mug recipe dropping in the morning. I think you'll like it ;O)
S. E. says
Holy delicious!!! I love it as written, but if you ever try subbing the sugar for brown sugar it is DIVINE!!! Costco makes really good dairy free chocolate chips (just check the packages because sometimes they change manufacturers). This recipe is a keeper and if you really want to step it up add some dairy free vanilla ice cream on top! Excellent recipe…no regrets on doubling it every time.
Hege says
This is a dangerous recipe to exist in the world! I am obsessed! So simple and delicious. All the best things about a cookie fresh out the oven. YUM.
Melanie McDonald says
So pleased you're enjoying it! Watch out for a new mug recipe coming up in about a week. I think you'll like it ;O)
Margie McGee says
Please...what size mug should I use???
Melanie McDonald says
Just a regular-sized mug you drink your tea and coffee from. They are usually about 11 or 12 oz. It doesn't really make a difference though so no need to be exact.
Annalise says
I make this recipe alllll the time and it’s one of my all time faves. I’ve found substituting things doesn’t really work well so I stick to the recipe. I use tahini as my oil and frequently use less sugar but that’s the only change I recommend!
Kate says
I usually don't review recipes but I'm hoping to offset Jen's 2 star review where she changed the recipe and then rated it 2 stars?? Who does that? Anyway, this is my absolute favorite mug dessert recipe! I have been making it for years and it's always such a nice treat for when I want a chocolate chip cookie but don't have any on hand. You definitely have to be used to baking with ground flaxseed but like... it's a vegan mug cookie; flax and vegan baking go hand in hand. I don't mind the little flax bits and don't find that it changes the flavor.
Melanie McDonald says
Thank you so much Kate. I'm really pleased you're enjoying the recipe!
jen says
unfortunately I failed with this recipe. I used almond flour as can't digest grains but otherwise all the rest of the ingredients I followed. It came out like a dense cake, not sweet enough but ate it anyway. Guess almond flour cannot be subbed in this recipe:(
Melanie McDonald says
So you don't follow the recipe then rate it 2 stars.....Thanks so much. For future reference star ratings affect how my recipes rank in Google, which has consequences on my income.
Marcy says
Just me and my non vegan, non loving chocolate chip cookie husband. So grateful for this one serving recipe! Excellent. Used the Enjoy Life brand of chocolate chip chunks. 😋 . . . . no flax seed on hand, but looked up a sub on the internet and they said almond meal. I had almond flour, and used it. Not sure if this was tops for this recipe but it is a winner in my book!!!! I'm high elevation so added a little extra regular flour. Delicious!
Melanie McDonald says
So pleased you enjoyed it, Marcy!
brianna says
I started making this before realizing I was out of flax, but I used the same amount of bob's red mill egg replacer and it worked just as well!
Maureen Cram says
Could this be prepared and then frozen for nuking later on? Thinking of making some of these for my son's coffee shop.
Melanie McDonald says
I have never tried it. You'd have to be careful about putting a frozen mug/ramekin in the microwave as they might break.
Sundae says
This was yummy, I’ve been looking for a dairy free mug cookie. It almost didn’t make it into the microwave!
