Keto Cinnamon Roll Mug Cake

What Is A Low-Carb Mug Cake?

A low-carb mug cake is like a muffin in a cup made with low-carb flour and baked in the microwave.

Keto mug cakes or low-carb mug cakes are great ways to fix sweet cravings without adding sugar or high-carb food to your day.

A low-carb mug cake usually contains about 7 grams of net carbs, but I recommend serving 2 mug cakes with this recipe to lower the carbs to 3.7 grams!

Plus, half of the recipe is very fulfilling, sweet, and enough to fix a sweet craving.

Is Cinnamon Keto-Friendly?

I am sure you wonder if it’s good for people with diabetes or on a low-carb diet to eat cinnamon. Yes, absolutely.

I would even say eat your cinnamon daily to keep your blood sugar level steady and avoid an energy crash.

Cinnamon is good for people with diabetes or on a keto diet as it helps lower the blood sugar level while less than 1 gram of net carbs per teaspoon.

So cinnamon is a great keto-friendly spice. I think people wonder if cinnamon is keto-friendly because it is often associated with sugar glazing, which is, of course, not keto-friendly.

But cinnamon itself is keto-approved given the amounts we use in recipes.

Another good news is that you don’t have to eat much cinnamon to get the positive effects. Studies show that our blood sugar level lowers with 1 gram to 6 grams of cinnamon a day.

It means that this cinnamon muffin in a mug is all good for you, and you shouldn’t wait any longer to try it!

How To Make Keto Cinnamon Mug Cake

First, gather all your ingredients on the benchtop. A tall mug – 6 cm high – is ideal for preventing the batter from overflowing in the microwave.

The ingredients you need are very simple low-carb ingredients that I am sure you have at home.

Ingredients

  • EggEggs are keto-friendly ingredients.
  • Almond Flour or almond meal both work well in this recipe. I prefer an almond flour mug cake rather than an almond meal mug cake. In fact, almond meal has a gritty texture and darker color. As a result, almond meal mug cakes are darker in color with a rough, gritty texture. Learn how to choose your keto-friendly flours.
  • Sugar-free Crystal Sweetener – I always use Monk fruit stevia blend or erythritol stevia blend. Check out my keto sweetener review for alternatives.
  • Coconut Oil – or any vegetable oil or butter if preferred.
  • Baking Soda – this will raise the keto mug cake and create a soft, airy muffin-like texture.
  • Ground Cinnamon

Instructions

This cinnamon mug cake has no milk, which means it’s also suitable for people on a paleo diet.

The cinnamon glazing that makes this keto cinnamon cake taste like a traditional cinnamon roll uses dairy-free ingredients.

Grease a small microwave-proof ramekin or mug with coconut oil. This is to make it not stick to the mug.

Cinnamon Mug Cakes rise quite a lot when cooking in the microwave, so pick a tall mug.

Beat the egg in a mixing bowl and add the melted but not hot coconut oil (or melted butter), and crystal sweetener.

Add the almond flour, baking soda, and cinnamon, and combine the batter so there are no more flour lumps.

Transfer the batter to the two ramekins and place them in the microwave.

Cook the Keto Mug Cakes for 80 to 90 seconds. Let them cool down for at least one minute before serving or before adding the cinnamon glazing.

Keto Mug Cake Cinnamon Glazing

This cinnamon mug cake won’t be complete without the cinnamon glazing that makes it looks like a keto cinnamon roll mug cake.

This is the cherry on top of the cake! It adds moisture, and delicate sweetness to your mug cake, and you will feel like eating a low-carb cinnamon roll.

The secret to dairy-free white glazing is to use coconut cream – or pure dairy-free coconut yogurt made of 2 ingredients, coconut cream, and probiotics.

The cinnamon drizzle is a simple combo of peanut butter, cinnamon, coconut oil, and sweetener. Fix your sweet tooth now.

Try this mug cake recipe. You won’t regret it.

Frequently Asked Questions

How Many Carbs Are In Cinnamon Mug Cake? 

Yes! This low-carb mug cake is made with almond flour. Almond flour is one of my favorite keto flour. I listed the top reasons below. Per serve (1/4 cup) almond flour contains:

  • Only 3.8 grams of net carbs. 
  • 3 grams of fiber which is good for your gut health and digestion.
  • No gluten.
  • A light texture and flavor similar to high-carb flour, perfect to create airy low-carb baked goods like muffins.

Can I Bake A Mug Cake Without A Microwave?

I’m sure some of you don’t have a microwave, or for some reason, you don’t like to bake in the microwave.

I’ve got you covered. Simply place this muffin batter into an ovenproof ramekin or muffin tray.

The baking time range is 12 to 15 minutes at a temperature of 350°F (180°C).

A great test to check the baking is to insert a pick in the center of the muffin. A clean pick means it’s cooked.

Making Mug Cakes Ahead

We are busy people, right? The good news is that you can prepare the mug cake batter the previous day.

Store the batter in the fridge in your mug. Cover the mug with a silicone lid or plastic film wrap to prevent air from entering.

The next day, microwave for 90 seconds on high. Your mug cake will come out as great as a fresh bakery muffin.

I don’t recommend baking the mug cake ahead as food baked in the microwaved hardens very fast. It is better to eat a mug cake within 1 hour of making it.

Ingredients

Cinnamon drizzle

Instructions

  • Grease a 3.5-inch microwave-proof ramekin or mug with coconut oil. Make sure it's tall enough to prevent the batter from overflowing when baking. Set aside.
  • In a small bowl, beat together egg, oil or butter, and sugar-free crystal sweetener. Make sure your oil or butter is not too hot, or it will 'cook' the egg and create lumps. Wait for a few minutes after melting the oil before adding with egg.
  • Stir the almond flour in baking soda and cinnamon. I recommend 1/2 teaspoon of ground cinnamon for a light cinnamon flavor. Add up to 1 teaspoon if you are a cinnamon lover!
  • Transfer the batter into two ramekins and microwave for 80-90 seconds individually. Time varies slightly depending on microwave power. The longer, the dryer. The best is to start with 80 seconds, check and return for extra 10 seconds if you like.
  • Cool it down for 1 minute before adding fresh dairy-free coconut yogurt. Coconut yogurt is made of 2 ingredients: coconut cream and probiotics. Don't use flavored coconut yogurt that will contain added sugar. Otherwise, use plain Greek yogurt if you eat dairy.

Cinnamon drizzle

  • In a small mixing bowl, add peanut butter with coconut oil. Microwave for 30 seconds to melt the coconut oil and easily combine both ingredients.
  • Stir in ground cinnamon, sweetener and use this mixture to drizzle on top of the yogurt.
  • Eat immediately.
Baking: if you don’t have a microwave, you can bake this cinnamon mug cake in the oven at 180C (350F) for 12-15 minutes.
Peanut butter swap: you can replace the peanut butter with any sort of nut butter like almond butter or sunflower seed butter, or tahini. All these options are low-carb and keto-friendly.

    I just made this recipe replaced the sugar with msple extract. Was very moist after 80 seconds. Delicious thanks

    • Thanks for the lovely feedback! I love the idea of using maple extract, it must have taste fabulous! XOXO Carine.

    • There is definitely print options on all my recipe. First one is on top of page after the recipe title, there is a ‘print recipe link’. Second is in the recipe card next to rating, another ‘print recipe link’ on your right. Can you tell me which device you are using that I can check if there is any technical bug but from my laptop I see the print link and they work well. XOXO Carine.

    This cake along with the chocolate mug cake have become a staple for me and are on high rotation! It is so delicious,filling and quick! The texture is so cake like and fluffy, you really wouldn’t know you are eating a ketonised version of cake! So indulgent yet healthy!

    This made my entire morning! I don’t have a lot of energy to make extravagant things on keto due to chronic illness but this is so perfect. I skipped the drizzle and added whipped topping, but the mug cake itself is absolutely perfect in taste and texture. I paired it with a cinnamon coffee and am in absolute heaven.

  5. I don’t see any mention of coconut yogurt in the in ingredients! Did I miss something. I would prefer not to add this. Does this add many carbs?? Thank you!!

    • Coconut yogurt is only used as a topping and it is optional. Coconut yogurt contains zero carbs, zero sugar it is made of coconut cream and probiotic. It will had fat to your mug cake which is actually great if you are on keto low carb diet! Enjoy the treat. XOXO Carine.

    • It appears at the bottom of the recipe card after the instructions and video. Enjoy the mug cake! XOXO Carine

    • You probably could but you will need less, probably 1/4 of the amount of almond flour I used as coconut flour is 4 times more liquid absorbent. Enjoy the recipe! XOXO Carine.
