Keto cinnamon mug cake or cinnamon muffin in a mug is an almond flour mug cake perfect to fix your cinnamon cravings. It tastes like a cinnamon roll with only 3.4g of net carbs to your day. A delicious sweet keto breakfast or snack recipe ready in only 90 seconds! Bonus, this low-carb mug cake is also paleo and gluten-free as well as dairy-free!
A low carb mug cake is like a muffin in a cup made with low-carb flours 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 7g of net carbs but I recommend serving 2 mug cakes with this recipe to lower the carbs to 3.7g!
Plus, half of the recipe is very fulfilling, sweet, and enough to fix a sweet craving.
Calling all the cinnamon lovers!!! You deserve a cinnamon muffin for breakfast even on a low-carb diet. This mug cake is the best way to fix your muffin cravings with very few carbs and in only 90 seconds. Are you wondering how to make a keto cinnamon mug cake? Stay with me, I gonna tell you everything about this easy low carb recipe.
First, gather all your ingredients on the benchtop. A tall mug – 6 cm high – is ideal to prevent 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:
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. But cinnamon itself is keto-approved given the amounts we use in recipes.
Another good news is, 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!
Yes! this low carb mug cake is made with almond flour. Almond flour is one of my favorite keto flour. I listed the top reason below, per serve (1/4 cup) almond flour contains:
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, use dairy-free ingredients.
This cinnamon mug cake won’t be complete without its cinnamon glazing that make it looks like a keto cinnamon roll mug cake. This is the cherry on top of the cake! It adds moisture, 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.
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 12-15 minutes, temperature 180C (350F). 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.
We are busy people, right? Good news, you can prepare the mug cake batter the previous day. Store the batter in the fridge into your mug. Cover the mug with a silicone lid or plastic film wrap to avoid air to enter.
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.

I loved it! So satisfying, thank you for the lovely fluffy Cinnamon mug Cake! I used the cream cheese for the topping..
We forgot to take pictures. Next time. And there will definitely be a next time.
I amended your recipe and technique based off n things I learned in school and my own experiments. Here’s what I did.
First, I used an extremely high quality, fresher cinnamon than what is typical in supermarkets because it is the primary flavor. Check out Penzy’s. You will love the rich flavor.
I beat the egg on high until it was very, very pale and fluffy. While it was just starting to get frothy, I added a pinch of salt,and 3/4tsp of cream of tartar. Still beating, I slowly drizzled in the melted oil to create an emulsion. This adds structure. The salt adds flavor and helps aerate the egg, for structure. The acid from the cream of tartar helps the egg hold it’s shape too.
The rest of the dry ingredients got sifted twice after being whisked together. This prevents heaviness and promotes a light, spongy crumb. The second whisking was directly over the egg mixture, and instead of stirring, I folded it in.
I chose to use almond butter, because I made some the other day from smoked almonds. To sweeten the glaze, I used Brown Swerve. It really tastes caramelized. Kinda. It’s close to brown sugar.
Thank you for the recipe. These were so, so very good.
Hey. You know your ingredients list doesn’t include the coconut cream/yogurt? Also, when you say to add the nut butter and coconut oil to a small mixing bowl, you should consider specifying microwave safe in the same sentence, or state these ingredients as melted in the ingredients list. Otherwise, your reader might already have it in a metal or plastic bowl by the time you mention melting them. Humble suggestion. Love this blog!
Icing is delicious. The cake is almost inedible like cardboard.
It should taste like ‘cardboard’ at all except if you over bake the mug cake. This happens if your microwave has a power >900W. This recipe cooking time is designed for this power and you must set the microwave to set powder to have the same texture with 90 seconds baking time. Otherwise, if you can’t change the microwave power you must decrease the baking time, starting by 60 seconds and increase by 10 seconds burst until moist and cake like texture. Enjoy, XOXO Carine
I made this (admittedly with brown sugar in place of the sweetener) and it was delicious! I also added a few shakes of salt to both the cake and topping, to get a little salty and sweet action. I used vanilla yogurt for the topping under the drizzle. Fabulous! Thank you!
Thank you! So happy you love it. Enjoy the recipes on the blog, XOXO Carine
Hi. I’ve not made this yet, but in the picture what is the white part of the frosting?
You can simply blend powdered erythritol with water or with soft cream cheese and drizzle, Enjoy, XOXO Carine
Good thing we eat our mistakes! Looks terrible. Didn’t ‘cake up’ like it should have. The drizzle remained fully liquid. But my husband loved the flavor and ate it anyway.
I am sorry to hear that. Happy to help you make this better next time. Maybe it didn’t cook long enough to get a cake like texture. Regarding the drizzle, you can make it thicker by adding less water or more sugar free powdered sweetener. Each brand have different texture and the ratio liquid/solid can be impacted based on the brand you used. Enjoy the recipe around here, XOXO Carine
Ottima, grazie per la ricetta! Saluti dall’Italia
I was so intent on leaving a comment that I forgot to rate the recipe! 5 star all the way!
Thanks SO much! So glad you enjoy this simple keto mug cake, XOXO Carine
I was craving a keto dessert while watching a Food Network tournament (lol) and found this recipe. The mug cake topped with the peanut butter drizzle was outstanding! I will make this again and experiment with a cream cheese topping like you put on a cinnamon roll. Thanks for posting!
Thanks for trying my recipes! The cream cheese frosting is a great idea, I am sure it will taste amazing. XOXO Carine.
It’s the best I tried! Only I added one extra tablespoon of almond meal to give it extra firmness and texture. Thank you very much for the recipe

why cant I print a simple recipecard?
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 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.
Thanks for the lovely feedback! Enjoy the recipe around here, XOXO Carine.
It was amazing, fix my cinnamon roll craving in a minute thank you Carine for great recipe.
Thanks for the kind message ! I am happy you enjoy this mug cake too. XOXO Carine
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.
so what are the other nutritional items. protein fat total carbs not net
It appears at the bottom of the recipe card after the instructions and video. Enjoy the mug cake! XOXO Carine
Can you use coconut flour? I have an allergy to almonds. Thanks!
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.
