The delicious healthy mug cake that can be made in the microwave, oven, and even air fryer.

1-Minute Cinnamon Roll Low-Carb Mug Cake

Cinnamon rolls are one of those sinfully good treats that even when you aren’t following low-carb you know you should only have every once in a while. The same concept should be applied to this low-carb cinnamon roll mug cake.

While this mug-cake only has 6g net carbs, a regular cinnamon roll can have between 30-70g net carbs, it is the highest net carb count of all my mug cakes.

If you are eating low-carb you can enjoy this cake as breakfast or a treat.

However, if you are eating keto only this cake will likely need to be eaten as breakfast and not a treat.

How To Make Cinnamon Roll Low-Carb Mug Cake Batter

To make the batter for your mug cake you will first want to add the butter and cream cheese to your mug. Melt the butter and cream cheese in the microwave on high for 20 seconds.

Next mix in the remaining batter ingredients except for the brown sweetener and cinnamon. The brown sweetener and cinnamon will be used to make a cinnamon swirl in your cake later.

Be sure to scrape the bottom and side of the mug while mixing. Once done it is time to make your cinnamon swirl.

How To Get That Cinnamon Swirl In Cinnamon Roll Low-Carb Mug Cakes

To make the cinnamon swirl combine the brown sweetener and cinnamon together in a small dish. It won’t mix completely, but that’s ok.

Next, pour the cinnamon and brown sweetener mix over the top of the batter. Using the back of a fork swirl the cinnamon mixture into the batter using a circular motion.

You want to try to push the cinnamon into the batter, but you don’t want it completely mixed in.

How To Cook Low-Carb Mug Cakes

Now it is time to cook your mug cake. Place the cake in the microwave and cook it on high for 60 seconds.

Use a toothpick or knife to check the doneness of the cake. If a toothpick or knife comes out clean when inserted into the center of the cake it is done. If the batter comes out of the knife it needs to cook a bit longer.

Cook the cake for a little longer in 20 seconds increments until the cake is done. It only took 1 minute to cook in my microwave.

Air fryer

To cook mug cakes in the air fryer you need to find a small baking dish or ramekin to fit inside your air fryer. There must be at least 1 inch on all sides to allow the heat to circulate evenly.

  1. Preheat your air fryer to 180C/350F.
  2. Place the butter in your small baking dish and heat for 30 seconds to 1 minute, or until completely melted.
  3. Make the mug cake following the recipe card below.
  4. Gently lower your baking dish onto the air fryer wire rack. Ensure there is plenty of space between the ramekin dish and the side of the basket.
  5. Cook for 10 minutes, depending on the size of your air fryer and the size of your ramekin or small baking dish.

Making Cream Cheese Icing/Frosting

While your cake is cooking in the microwave whip up your cream cheese icing/frosting so that it is ready. To make the keto cream cheese frosting simply mix the cream cheese, sweetener, and vanilla together in a small dish with a spoon.

The cream cheese will soften as you mix it. When it is mixed, use the spoon to spread the icing over the warm cinnamon roll mug cake so that the heat makes the icing soften and melt.

What if You Don’t Have A Microwave? – No Problem

If you do not have a microwave or don’t like to use them you can still make this mug cake. You will instead want to bake your individual cake in the oven using a cupcake pan or oven-safe ramekin.

Bake the cake at 180C/350F in the oven for 12 minutes, or until it is done.

How To Serve And Eat Low-Carb Mug Cakes

Your mug cake can be eaten directly out of the mug, or remove the cake from the mug to serve it on a plate.

This cinnamon roll mug cake is delicious and is perfect for satisfying that sweet tooth every once in a while.

    This is fantastic! One of the few keto mug cakes I have had, in almost 5 years, that was not gummy or rubbery. Thank you so much!

    1. 5 stars
      Absolutely ADORE this. Skipped the icing and used sugar free golden syrup and it tasted like pancakes! Absolutely amazing.

      1. 3 stars
        Mine didn’t turn out. It was too dry, but may have been the large egg. My boyfriend liked it a lot, but I would pass on trying to make it again

        1. 5 stars
          Yes, using a large egg when the recipe calls for a medium egg will probably have required you to microwave it for a little longer than suggested. I’m glad your boyfriend enjoyed it, maybe next time you might want to try my vanilla berry mug cake, it’s the most popular mug cake on the website.

    This was really good and tasted similar to the real thing.
    Thanks for sharing!

    Have been wanting to try a “mug cake” for quite some time. …finally tried the Cinnamon Bun version today. Oh my – what was I waiting for??

    Just delicious!! The texture was spot on! My microwave is quite old, I cooked it for 1 minute 50 seconds – but it was perfect! I used an oversized, tall soup mug, and was glad I did!

    Thanks so much for sharing this recipe with us!

    Why would someone choose to count net carbs vs total carbs?

    oh my goodness. This is such a great recipe. Normally I dont like using cocunut flour but this has made me a believer!

    thank you

    INCREDIBLE mug cake! I’ve made other keto cinnamon roll mug cakes, but this one is far superior! When you’re a family of two, there’s no need to make a whole pan of cinnamon rolls (too tempting to eat all lol), so this recipe is perfect! I also love that it uses coconut flour yet is very moist. Thank you, Libby!

      What a kind review. I agree, single-serve desserts help us so much to stick to our low-carb or keto diet. Thank you, Karen.

    Cinnamon roll satisfaction!

    Thank you a thousand times – I have never used microwave for mug cakes, first time I tried – I didn’t even have cream cheese – I used cottage cheese and cooking cream. It turned out MAGIC! Finally I have a dessert I can do quickly that tasted so so good. @ketonordics

    Loved it!
    Coconut flour is a nice change from almond. Very filling too. Next time I’ll add a little more brown sugar and cinnamon. Thanks so much!

  10. Can I use almond flour instead?
