Cinnamon Keto Mug Cake

Cinnamon Keto Mug CakePin recipeFollow us 54.0k

This single-serving, low carb cinnamon mug cake is just what you need when you crave something sweet. It takes less than five minutes and you'll need just a few ingredients. It's moist and is best served with a dollop of whipped cream, coconut cream or full-fat yogurt. It's not too sweet so if you prefer your keto mug cakes sweeter, add a few drops of stevia or a little more erythritol.

Ingredients (makes 1 serving)

Tips for substitutions: If you want to make the recipe nut-free, use 1 tablespoon of coconut flour instead of 2 tablespoons of almond flour. If you don't have coconut flour, you can use 2 tablespoons of finely shredded desiccated coconut instead.

Too "eggy"? Although I like this combination, some of you may perceive it as too "eggy". You can try the following: use one egg, double all the dry ingredients and add ¼ cup coconut milk, almond milk or cream. This mixture will make 2 mug cakes. Instead of the listed sweeteners, you can try other healthy low-carb sweeteners from this list. The reason I'm using both Erythritol and stevia is to mask the aftertaste some of the sweeteners may have.


  1. Place all the dry ingredients in a mug or ramekin and combine well. Cinnamon Keto Mug Cake
  2. Add the egg and coconut oil and mix until combined. Cinnamon Keto Mug Cake
  3. Microwave on high for 70-90 seconds. When done, you can optionally top the mug cake with whipped cream or creamed coconut milk and a pinch of cinnamon.
    Cinnamon Keto Mug Cake Tips for cooking in the oven: If you don't have a microwave, I suggest you make 4-8 servings at once. Preheat the oven to 175 C / 350 F and cook for about 12-15 minutes or until cooked in the centre. Cinnamon Keto Mug Cake

I changed the way I ate in 2011, when I was diagnosed with Hashimoto’s, an autoimmune disease that affects the thyroid. I had no energy, and I found it more and more difficult to maintain a healthy weight.

That’s when I decided to quit sugar, grains, and processed foods, and to start following a whole-foods-based ketogenic approach to food.

I made this recipe this morning for breakfast.  MMM-MMM Good isn't words enough.  Great recipe.. Tastes just awesome.  Because it's a bit dry, I added cool whip (I didn't have whipped cream).  It did the trick!! Thanks so much for this recipe.  It's definitely a keeper!


Thank you Nola, I'm glad you liked it!


I tried this for the first time.  Taste was great but was a little dry.  What could be the problem?  


I think this is this cake is drier than other mug cakes - I usually serve mine with yogurt or some whipped cream. If you prefer the mug cake more moist, try some of these: Best Keto Brownie Mug Cake, Low-Carb Red Velvet Mug Cake or Keto Berry Mug Cake
I hope this helps! 😊


Simple and sweet! Looks great.
Personally, I love mug cakes. I have a bit of a sweet tooth and I'd rather not bake an entire batch of something, just in case it disappears. At least with a mug cake, I know I'm not going to eat too much.


Thank you Vince. I agree, I prefer making just a serving rather than a whole batch 😊


If the cake is "eggy" then the recipe requires 1/3 tsp vanilla per egg.
In every recipe the smell of the egg yolks can be cancelled by vanilla.
And even though this is a cinnamon mug cake the vanilla disappears too!
I hope this helps.

Thanks for the tip Gladys!
