Satisfy your cookie dough and/or cake craving in less than 5 minutes with this delicious oatmeal cookie dough mug cake! Soft and doughy, this mug cake is gluten-free and made without butter or oil. Quick, easy, and single-serve. The perfect healthy snack!
If you use a microwave to make something, does that mean it’s technically no-bake?
No, seriously. I was trying to figure out how to categorize today’s recipe, and I didn’t know whether or not I should check the little box marked “no-bake treats.” So I did what I always do when presented with one of life’s many mysteries — I got my geek on and Googled it.
Bake:
: to make (food) by preparing a dough, batter, etc., and cooking it in an oven using dry heat
: to cook (food) in an oven using dry heat
: to dry or harden by subjecting to heat
And just like that, the mystery is solved. Now, I’m no expert in microwaves, but I do believe they use electromagnetic waves to zap the living bejeezus out of things, which technically means that this oatmeal cookie dough mug cake is, in fact, no-bake…
And it’s a good thing, too, because with Sunday being the first day of summer (what, what!!), the last thing anyone wants to do is fire up the oven and add a few degrees to the already sweltering inferno that is the summertime kitchen. Although, let’s be honest, I’ll be firing up my oven/stove anyways, because I really wasn’t kidding when I said I’m no expert in microwaves.
See, I grew up without one so I’m used to getting by without one. My mom has always been pretty health conscious, and she read something somewhere about how microwaves aren’t good for us, and that was the end of that — no microwave in our kitchen. But don’t worry; I’m not here to tell you that microwaves are evil and you should avoid them like the plague, because I don’t know that they are. Some people say yes, some people say no — at the end of the day, it’s not going to make or break your health goals.
It is however, going to allow you to satisfy your cookie dough and/or cake cravings in less than 5 minutes flat…
It’s been a hot minute since I shared a mug cake recipe with you guys, and I honestly have no idea why since they’re basically the epitome of perfection.
Quick,
easy,
single-serve,
no-bake ( 😉 ),
sweet,
doughy.
So, so doughy…
That right there is texture perfection, friends.
I feel like I profess my love for coconut flour in every mug cake recipe that I post, but it really does make all the difference in these guys. It makes them soft and fluffy, while still giving them a denser, more substantial texture that’s oh.so.satisfying. And it’s gluten-free, to boot! Yep, coconut flour is magic, and if you’ve never tried it before, then I highly suggest picking up a bag just so you can try it in mug cakes. It makes that big of a difference.
As do egg whites. I tried subbing in a few different binders, and I have to say that the egg whites were by far my favourite.
The one on the left was made with an egg white, while the one on the right was made with applesauce. It still tasted great, but it didn’t set as well, so it didn’t end up being as soft and fluffy as the one made with the whites. I was kind of bummed about that, but like I said, it still tasted delicious so you could easily go that route if you’re vegan or allergic to eggs.
Other than that, there’s not much left to say! This mug cake make a great afternoon or after-dinner snack. It’ll satisfy your cravings for something sweet and doughy while being made with healthy ingredients that you can feel good about eating. And the best part is that it comes together in a snap, and it’s single serve so you don’t have to worry about leftovers lying around. Hope you love it as much as I do!

Just to let you know I have successfully made this with an egg substitute! It didn’t look pretty it it tasted awesome.
I mixed 2 tsp milled chia (you could use ground flax) with 2 tbsp water, left it in the fridge for 5 mins and added instead of the egg white.
Thanks so much for commenting with your substitutions, Lucy! I’m sure other readers will find it helpful 🙂
I used a few different ingredients and I didn’t think it would matter, but it did. I used steel cut oats, TJ’s gluten free all purpose flour, coconut milk and raw organic sugar. I don’t know what happened, but it was all kinds of wrong. huh. Well, I ate enough chocolate chips in the process that it satisfied my craving. May try again if I have the exact ingredients. I love the idea.
Hi Brittany! The steel cut oats were most likely the culprit. They take a lot longer to soften up than rolled oats do, so they’d pretty much still be raw and crunchy after only a few mins in the microwave.
made this with a whole egg, added some cinnamon, nutmeg, walnuts aaaaand coconut flakes n it was delish! my first mug cake ever! thank you!
Can I use almond meal instead of the coconut flour?
Unfortunately no. Coconut flour is unique in the way it absorbs liquid, and that’s what allows this mug cake to stay nice and moist without any oil. If you swap out the coconut flour, the texture will be completely different.
Where do you get a mug like that?
It’s so big.
I got it from Homesense a handful of years ago, but it’s actually just a regular sized mug. Pictures can make it hard to tell how big something is.
Can this recipe be cooked in the oven because I don’t have a microwave?
Hi, I am a huge fan of your recipes! I was wondering if this oatmeal cookie dough mug cake can be cooked in the oven as I don’t have a microwave??
Thanks!
I haven’t tried it personally, Ruth, so I can’t say 100% for sure… but I don’t see why it wouldn’t work. You would probably have to bake it anywhere from 15-20 minutes though.
Just made this…ok actually made 2 because the first was so good my little guy ate half. I justified that as needing to make us a second to share. Only thing was it was fully cooked in my microwave in a minute and 20 seconds.
I tried this, It’s very eggy and formed to a shape. I wouldn’t try this again, but maybe tweaking the recipe. Otherwise it’s not too sweet which i liked. (:
I’ve tried SO many mugcakes and they all usually turn out like hockey pucks. But I just made this one and it’s AMAZING. I subbed the coconut sugar for turbinado sugar, and it turned out great!
I’m glad you liked it, Lacey! Thanks for rating the recipe and letting me know 🙂
Does this mug cake taste very coconut-y? I’m not a huge coconut fan but I would love to try this and your other mug cakes.
I like your definition of no bake, it works for me and this sounds FABBBBBUUU 🙂
Ever since I made my husband a brownie mug cake he has become obsessed. He LOVES chocolate chip cookies, and because this treat is healthy, I won’t feel bad making it for him, even if he asks for it every night! Beautiful pics, btw! 🙂
Oh my goodness, this looks and sounds heavenly!

This needs to happen immediately! Cookie dough healthified? Yes, please!
Great recipe! Needed a new mug cake recipe, getting a little tired of my usual one!
Inspires me to make some.
I made cake last night too. Granted it was filled with all the things omitted from this recipe, but I’m excited to eat it. It’s a Strawberry Rhubarb Upside Down Olive Oil Cake, and the olive oil makes it dreamy and so very moist, which is perfect in a cake. It’s also icing free since the top layer is a combination of sweetened rhubarb and strawberries.
Confession: I’ve never eaten anything with rhubarb before. Want to be the one to pop my rhubarb cherry? 😀
Dirty birdie. Sign me up.
Not even being cheesy but I love that spoon…the picture spoon.
Coconut flour may be my all time favourite baking/non baking item ever.
