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.

  1. 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!

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

      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.

  3. 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!

  4. 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.
