Cinnamon Roll Keto Mug Cake


Cinnamon… Where do I start Cinnamon is an incredibly versatile spice. It’s one of those spices some consider a cure for “what ails ya”. Others use it to flavor anything and everything especially baked sweets. I fortunately (or unfortunately) belong to neither group.

Believe it or not, there are different types of cinnamon. The less common variety is called Ceylon, which is rare and more expensive. It has a mellow, fruity flavor and is often called the “true” cinnamon. Cassia, which is most common in the United States, has a stronger, spicier flavor. Unless you’re paying top dollar for your cinnamon, you’re using cassia.

One of our local bakeries makes some of the most delicious looking cinnamon buns I’ve ever seen. If we’re being honest, everything they make looks amazing, but that’s beside the point. 

Admittedly, I’ve never had one of their cinnamon buns but I frequent the bakery to pick up treats for my non-keto wife. During my pre-keto years, I had a few utterly amazing cinnamon sweets. They were usually my go to pick, as I loved the combination of cinnamon and sweet.

Cinnamon Roll Keto Mug Cake

The key, at least in my opinion, to a good mug cake (or any cake) is to be moist. This recipe achieves just that. 

If you are a fan of cinnamon buns, you can’t pass up this cinnamon roll keto mug cake. It makes the perfect breakfast, dessert, or sweet treat.

Go ahead. Treat yourself. You know you wanna.

    I tried this, it is very good but what disappointed me is that after it looked like the picture you have here it collapsed and turned into a hockey puck and was not very big in the mug. I did a good job mixing it and everything. So I don’t know what happened? Did I need to use the regular oven? Or did the baking powder fizzle out at the end? I wish it stayed big and puffy.

      I have always found mug cakes can be hit or miss when it comes to “fluff.” Sorry that happened, but I don’t really have a good answer for you. It happens to me from time-to-time as well.

  2. This was pretty freaking good!

    Used Erythritol for sweetener, ghee in place of butter and skipped the cream cheese icing but added a small scoop of No Sugar Added So Delicious vanilla bean coconut milk ice cream. We usually make a chocolate mug cake but wanted to switch it up and this definitely hit the spot! Thank you!

  3. Is the carb count off on this? Just my almond flour alone was 6 carbs.. unless I’m doing something wrong here?

    • Logan Childress


      The carb count isn’t really off, no. All almond flours differ slightly in carb count, but all of our recipes are net carb count. There’s always a chance we make a mistake, but for the amount of almond flour used here, probably 2 net carbs max.

  4. This is very good! It’s the perfect way to start the day. I have been making it in a bowl. It does expand quite a bit (nearly doubled in my experience). My husband enjoyed it for breakfast today with a sausage patty. I did make a single serve frosting with 1 oz cream cheese, 3/4 T butter, vanilla and sweetener. I used a mixture of Erythritol and stevia (2 T) that I make myself. It is not over sweet and so nice for an early morning “healthy” breakfast. It is more like a cake than a cinnamon roll but the flavor is really nice. It’s a keeper. Thanks so much!

  5. Best mug cake yet!! I didn’t have any cream cheese for icing so I took two tablespoons of heavy cream, cinnamon to your taste, and two stevia packets, and whipped it up as icing, delicious.

  6. Are the nutrition facts for the cake with or without the icing? Thanks!

  7. Sara Chwatt

    IMO didn’t even need the frosting!.. It exploded a little bit but was worth it for the most delicious mug cake!! Substituted erythritol for monk fruit sweetener.. SO GOOD!!

  8. Best mug cake I have tried to date ? thank you!

  9. Laura Netherton

    What can I use instead of golden monkfruit sweetner?

    • Logan Childress


      You (generally) can use whatever your normal sweetener of choice is, just be careful of net carbs with a lot of powdered sweeteners. Most have serving sizes in teaspoon amounts, which means the company isn’t required to list any nutritional content, including carbs.

  10. So do you add the cream cheese icing to all the ingredients in step #2? Or isn’t that ingredient to top it? Confused.

    • Logan Childress


      Thanks for commenting and asking! The icing is used in step 6. We weren’t 100% clear on that, and we apologize. We are going to edit the second step to reflect the change. Thanks!
