Ingredients You’ll Need
- Almond flour – I personally prefer almond flour for this cake. Coconut flour changes the taste of the cake and makes it a little too coconuty for me.
- Baking powder
- Butter
- Egg
- Vanilla extract
- Granulated sugar substitute – I use allulose as a sugar substitute. You can use Swerve, monkfruit, Erythritol or Xylitol. It’s really up to you. The reason I use allulose is because it’s a no calorie no carb sweetener like erythritol, but it doesn’t have the cooling effect.
- Ground cinnamon
- Glaze ingredients – Cream cheese, powdered sugar substitute, and butter.
What Sugar Substitute to Use

The reason I use allulose is because it’s a no calorie no carb sweetener like erythritol, but it doesn’t have the cooling effect. I get allulose directly through Wholesome Yum. I think you’ll really like it, especially if you also don’t like the cooling effect.

How to Make Cinnamon Roll Mug Cake
To make a mug cake, you’ll need a microwave-safe mug that’s at least 10 oz. I use my regular coffee mug and it has plenty of space for the cake to expand. You can also use a 10 oz or larger ramekin.
Spray the inside of the mug with cooking spray or rub a little coconut oil inside the mug to prevent sticking.
Mix together the flour and baking powder, then add it to the mug.
You can use coconut flour instead of almond flour, but the batter might turn out dry, so you may need to add up to 1 tbsp of almond or coconut milk to the batter to smooth it out.
I personally prefer almond flour for this cake. Coconut flour changes the taste of the cake and makes it a little too coconuty for me.
Mix in the melted (but not hot) butter, egg, and vanilla. Stir it all up. It should be the consistency of regular cake batter. Not too dry, not too runny.
Next, mix the granulated sugar substitute with the cinnamon and sprinkle it on top of the cake.
It seems like a lot, but it needs to mix into the cake batter. I do this with a chopstick, because it’s thin enough to swirl without mixing. You can also use a knife.
Just swirl in the sugar, push the chopstick from top to bottom a few times. Don’t stir it up, though.
Put the mug in the microwave for 60 seconds. I use an 800 watt microwave and 60 seconds is perfect.
I’ve never had one come out not fully cooked, but if yours doesn’t seem springy and fully cooked, or if it still has a wet top (you can still see raw batter), put it back in for another 10 seconds. A lower wattage microwave might cook the cake slower.
Alternately, a higher wattage microwave could over cook the mug cake, so if this cake overcooks in 60 seconds, you’ll need to cut the time down or cook at a lower power next time.
While it’s cooking, mix up the glaze. It’s just softened cream cheese, powdered sweetener (like Erythritol or Swerve), and melted butter. Mix it up until smooth. You can heat it for about 10 seconds in the microwave.
When the cake is done, you can eat it directly from the mug, or turn it out onto a plate and drizzle with the glaze.

How Many Carbs Are in Keto Mug Cake?
If you’re wondering about the carbs, you’ll be happy to hear that 1 cinnamon mug cake is just 4 net grams of carbs.
That means you can eat the whole thing and not feel guilty about it. You only have to save a little room in your daily carb count for this treat.
I actually find that I’m not able to eat the whole cake in one sitting. It’s pretty rich! So I save half for later. For just 2 net carbs, that’s a win/win.
Tips and Notes
- 1 mug cake = 4 net carbs
- * You can use coconut flour instead of almond flour, but the batter might be dry, so you may need to add up to 1 tbsp of almond or coconut milk to the batter to smooth it out. It should be the consistency of regular cake batter. Wet, not chunky.
- I use allulose as a sugar substitute, but you can use Swerve, erythritol, or monkfruit in the same ratios. Allulose doesn’t have the cooling effect!
Keto Mug Cake FAQs
If you’ve never made mug cake before, you might have a few questions. Here are some of the most frequently asked questions I receive about this recipe.
How do mug cakes work?
Mug cakes are so easy to make that it gets you wondering how it works, especially since it takes so long to bake a cake in the oven. The magic of a mug cake is in the leavening agents, which are the egg and baking powder.
When heated, the baking powder reacts with the other ingredients and forms bubbles that help the cake rise, while the rest of the ingredients cook.
What do I need to make a mug cake?
You’ll need the ingredients (obviously), but then the only other things you need are a microwave and a microwave-safe mug. I just use my regular tea/coffee mugs. You could also use a ramekin. You just need a mug or ramekin that’s larger than the cake ingredients, because it does rise a couple of inches in the mug.
What wattage do I cook this on?
I cook my mug cake at full power in a 900-watt microwave. If you have a more powerful microwave, you may need to cook the cake for 70 or 80 seconds instead of 90. Once you’ve cooked one mug cake, you’ll know for next time.
In my opinion, it’s better to under cook then over cook, so if this is your first mug cake cook it for 80 seconds on full power. If it’s still wet in the middle, cook for 10 seconds longer. If it’s a bit tough or dry, you can reduce by 10 seconds next time you make it.

Definitely trying this! Love that it takes only one minute and is keto too! Love cinnamon rolls.
This was really good! But it did go dry with in 10 min of baking..
Might be because i didnt make the glaze, so Ill do that next time !
Thank you for a superb recipe!
I’m sorry to hear that it went dry. Definitely the glaze will help. If I have any left over, I always reheat it with the glaze on top and that brings it right back to moist.
Laura I made the recipe today. My husband is new to keto and he said it actually tasted like a cinnamon roll. I made it with coconut flour and it had good consistency. The only thing I didn’t care for is that it had an eggy taste to it. Anyway I can fix that?
I’m glad you and your husband liked it. The eggy taste is usually masked by the coconut flour, but the best way to cover it is with extra vanilla or cinnamon/nutmeg. I have been successful cooking it with only half an egg, too.
THIS IS AMAZING! I’M JUAT AS EXCITED EATING IT AS I WAS MAKING IT! THX FOR MAKING DESSERT SO KETO DELISH! MAD PROPS TO YOU MA!
So glad you liked it, Lucy! Enjoy
This keto cinnamon roll mug cake is amazing such a genius idea! SO good and less than ONE minute to make!! Amazing!
Seriously SO delicious and it came together so quickly! Love this.
You blew my mind with this! Cakes, brownies, sure! But a cinnamon roll?! YES!!
I love that too!
I loved it but I have a HUGE sweet tooth I’m trying to kick. The ONLY thing missing it seems to need sugar IN the bread, is there a reason why we don’t add it?
I don’t add it because the sugar topping is pretty substantial and it gets swirled into the bread. Not adding sugar to the batter helps keep it moist. If you like it sweeter, you can certainly add a bit of sugar to the batter, or mix in some of the sugar topping, then swirl in the rest.
Wow such a delicious way to start the day! I can’t believe how easy it is to make!!
Best part about mug cakes. So simple.
This recipe was delicious. It had the right amount of cinnamon and sweetness. I used lakanto and grinded it in my mini grinder to make powdered lakanto/ confectioners for the cream cheese icing. The recipe worked perfectly. Thank you for sharing it!
Glad you liked it, Sarah. And great tip about grinding the lakanto.
I have been making this on repeat..love your recipe..thank you
I have gestational diabetes and have been craving cinnamon rolls so bad. I found this recipe and decided to try it. It DEFINITELY satisfied that craving! So yummy!
I’m a diabetic and was craving something sweet. This was amazingly good! It was very moist and delicious! I’ll definitely make it again!
Glad you liked it, Toney!
the texture was great but it had a bitter taste, any idea since i’m the only one?
I’ve made this dozens of times and it’s never bitter. I’d suggest it was one of the ingredients you used. What sugar substitute did you use? Perhaps the almond flour brand?
It tasted a little bitter to me as well, but I think it was too much cinnamon and not the cake itself. Next time I will use half the cinnamon and add more sweetener to the batter.
Bitterness can be caused by the cinnamon and the type of almond flour you use. Make sure the almond flour is blanched (meaning no skins). You can also substitute coconut flour if you don’t like the bitterness of the almonds.
Awesome 👏 so delish!
Huge fan of mug cakes, and I don’t know if I’ve ever seen a recipe for a cinnamon roll in a mug before! Definitely need to try this one out!

Awesome. So good, I had to double the batch & share with my wife. This is great for breakfast or an after dinner dessert. The cake comes out moist & the icing gives it just enough sweetness, without over-load. Thank you for sharing this recipe.
Glad you liked it, Bryce! I agree, it’s perfect for breakfast.

Glad you liked it Lori. It’s definitely my go-to for sweet cravings.
This was amazing. Thanks for the recipe.
Loved it…. came out pretty decent… first success at any kind of mug cake. the topping i added a little orange extract….. was great for my sweet tooth craving that kicked in at night. Thank you .
I made this for my husband. He has a big sweet tooth and he is working on his keto. This was his fill day. He loves cinnamon rolls. So thank you so much. This was his favorite. This is a keeper.
I’ve been making chocolate mug muffins for awhile now, but this is the first cinnamon one that’s good. Now, when my family has cinnamon rolls , I can join them instead of watching them. I loved the cream cheese frosting. Delicious! Thanks 😊
I hear you on that, Beth. I still make cinnamon rolls for my husband and I make this version for myself.
Love it! Perfect size, not too sweet, easy to make. I have to keep this one on rotation. Thanks!
Does the net carbs include the icing? I really enjoyed it.
Yes, the carb count includes the icing! Cheers
I’ve been craving a cinnamon roll and this really hit the spot! Soooo good!
Thank you!
Roseann, so glad you liked it!
I am diabetic and trying so hard to be good. This just fixed my craving for cake! Thank you so much.
It’s great to hear that this fulfilled your craving without the sugar!
Ditto, lol
Definitely my craving killer! Thank you!
I drop 2 or 3 big blackberries in for a little extra sweet tartness. Absolutely perfect!
Ooh that sounds like a great idea!
Can this be baked in an oven, either toaster or regular? I don’t use a microwave oven. Thank you.
I’ve not tried cooking this recipe in the oven. It’s meant to be a quick microwave cake. If you put the mixture in a ramekin, you should be able to bake it on 350 degrees until it’s no longer wet in the middle, likely about 15-25 minutes. Check it with a toothpick to determine when it’s done.
I liked it a lot. Very easy and single serving perfect takes the sweet craving away
Glad you liked it, Raich!
Hi Laura,
I don’t use microwaves , can I make this in the oven ? If so how long do I bake it for ?
Thank you so much !!

This is soooo good even if you don’t follow all the directions as written. I put in the sugar before realizing it should be mixed with cinnamon. Then I used the extra melted butter w the cream cheese & melted it a bit too long so I just dumped it on the cake & it was just the right thing.
Well it sounds like it turned out just fine anyway! Thanks for your feedback.
I made this with my 5 year old gluten-free granddaughter. It was easy and delightfully delicious, even without the glaze! Thank you! We will be making this again.
The cake was moist and spongy, which surprised me. This is first time I have used almond flour in anything, so I was pleasantly impressed. However, I did feel the cake itself needed sweetening and I added about 1/2 tsp of sweetener to the batter, but the cake did taste a tiny bit bitter. I used allulose, btw. The glaze was good and helped a lot, but not quite enough. Next time I will add more sweetener to the batter and less cinnamon, which I think was responsible for the bitterness. But overall, a keeper. Thanks!
This was amazing! Seriously hit the spot after almost a month on keto/low carb
So glad you liked it, Jen!
I am diabetic and use a keto diet to control it. But I so missed cinnamon rolls and pancakes. This recipe fills that gap. As is it’s great. I reduced the cinnamon and omitted the glaze, added a pat of butter and sugar-free maple syrup after it was cooked and had a wonderful pancake in a mug.
That’s a great idea, especially if you’re wanting the maple taste, rather than the glaze.
I just made this cinnamon roll it’s delicious will make it again. Thank you for posting this recipe .
Hi Pat, glad you liked it! 🙂
OMG! I’m T2 diabetic and haven’t been able to have a cinnamon roll since 1998. THANK YOU!!! I ❤️ Cinnamon Rolls! I feel like a 5 yr old on Christmas morning.
That’s great to hear!
Fantastic!
Tried this tonight, I thought it was really good. But I’ve cooked with almond flour before and I know that these little almond flour mug cakes tend to be on the dry side. It’s just the nature of the beast. So knowing this from the beginning, I mixed in a little dollop off sour cream to the batter. It came out super moist without being gooey or too wet. Perfect!
Great idea Julie! Glad you liked it.
I made this almost to a T, with the following subs/swaps:
in the cake I used 1 tbsp unsweetened almond milk, instead of melted butter.
in the glaze, I used 1.5 tsp butter.
I was trying to save a bit of calories, which was why I switched to almond milk. But, then for the glaze, I just totally spaced out and added more for no reason lol. Either way, the cake came out perfectly, and flavor was spot on! Thanks for a great recipe!
Thanks for the feedback. Glad you liked it!
Delicious!!!!
This was amazing. Definitely will make it often!!!
Surprisingly delicious!
This is seriously SO good! Thank you so much for a good cake mug!
There are no measurements for the ingredient! Flour?? Baking Powder ???
Hi Annmarie, if you scroll to the bottom of the post there is a recipe card with all of the ingredient measurements. There are also some tips there too. I hope you like it!
I am in love with this!! I was very skeptical at first since I was going to do it Dairy-free! I substitute the butter for coconut oil and the cake came out so delicious!! I also substitute the cream cheese for non dairy sour cream for the icing and Ohmygoodness!! Delicious! Thank you for this recipe !!:)
This is fantastic. Instead of a whole egg, I used 1/2 an egg (25 grams) as well as buttermilk (25 grams) and a drop of vanilla extract. I also added about 1 Tbsp of sweetener to the actual batter. It really did taste like a cinnamon roll. I’m impressed.
