A fluffy cinnamon cake that tastes like a snickerdoodle cookie in cake form. This easy single serving cake cooks in the microwave and is gluten free, low carb and keto friendly.
Earlier this year I created an easy and tasty snickerdoodle mug cake. Now I’m sharing a low carb version. This cake is flavored with cinnamon and then topped with cinnamon and “sugar” to really feel like a snickerdoodle.
How to Make a Snickerdoodle Mug Cake
- You will need a microwave-safe mug that can hold at least 12 oz of liquid because the cake will rise quite high while it is cooking.
- All the ingredients are mixed together with a small whisk until the batter is smooth. The batter is then topped with a cinnamon sugar coating, much like the finish for a snickerdoodle cookie.
- The cake cooks at full power in the microwave for about 90 seconds. I use an 1100 watt microwave. You may need to adjust time and/or power if you are using a different wattage.
Low Carb Ingredients
- Instead of wheat flour, this cake is made with superfine almond flour.
- For the sugar alternative, I used erythritol sweetener granular. It looks just like granular sugar and melts well into the batter.
If you like this mug cake, I have several other low carb mug cakes including a keto chocolate chip mug cake and 3 ingredient keto peanut butter mug cake.

Low Carb Snickerdoodle Mug Cake
Ingredients
Cake
- 1 tbsp unsalted butter melted
- 1 large egg
- 3 tbsp superfine almond flour
- 1/2 tsp baking powder
- 1 tbsp + 1 tsp erythritol sweetener granular
- 1/2 tsp vanilla

Cinnamon Sugar Topping
- 1/16 tsp ground cinnamon
- 1/4 tbsp erythritol sweetener granular
Instructions
- In a microwave-safe mug (that can hold at least 12 oz of liquid), add all cake ingredients. Mix with a small whisk until batter is smooth.
- In a small bowl, add topping ingredients. Whisk until evenly blended. Sprinkle over surface of cake.
- Cook cake in microwave at full power for about 1 minute 30 seconds. Be careful to not overcook the cake because that will cause the cake to be dry when it cools. Allow the cake to cool a few minutes before eating.

This is amazing! I used 1 1/2 teaspoons of Pyure in place of the erythritol. JUST WOW!!! I baked it in a small bowl. Thank you for sharing your recipe. I can’t wait to check out your other ones. I posted to Instagram and tagged you. ?
Thanks for your nice review!
Tried the snickerdoodle mug cake and it was very delicious except for I forgot to add the erythritol granulated sweetener (well I used splenda that’s all I had) to the cake mix so it wasn’t sweet but was still pretty good!
We’re glad it worked that way!
this was just what i needed! I’ve been keto two weeks now, not long i know but I was craving something sweet and this delivered. I used granulated monk fruit for the sweetner. Thanks so much all the measurements were spot on. I will make again.
We’re so happy you tried the recipe!
I’ve made this numerous times and love it every time! So easy and delicious. This is my husband’s favorite as well and he’s a bit picky when it comes to keto recipes. It’s what we call a “make again-er” 🙂
thank you so much for sharing! I love that you call it a “make again-er”
The best mug cake I’ve ever made. Awesome. Helps meet those “I need something sweet” times and yet remain on Keto.
I’m so glad you liked it!
This is probably the most cakelike mug cake I’ve ever made. Very tasty and would be delish with some sugar free whipped cream 😛
We’re so glad you enjoyed it!
Yummy!
I’m glad you liked it!
So good! I’ve tried several keto mug cakes and this is my favorite! Well done and thanks for sharing!
I’m so glad you liked it!
I love snickerdoodle cookies, but being keto for the past six months, I haven’t made any of those wonderful cookies. I’ll definitely make this mug cake today (after I’ve had some sleep), but will use ghee in place of the butter, having a severe allergy to all milk-laden dairy. I’m looking forward to the cake 🙂
I hope you enjoy!
I have a terrible sweet tooth so being able to whip this up so quick and enjoy on keto was an absolute treat! It was so delicious thank you so much!
I’m so glad you liked it!
Can you bake these in the oven?
I have not tried
Hi! Is monk fruit sweetener with erythrotol equivalent do you think?
I think that should be fine
This is really good. I will make again and again.
I’m so thrilled you liked it so much!
Oh so good!! Quick and easy to make! The cake was done before I had cleaned up the few dishes I had made making this delightful treat! Thank you!
I’m so glad you liked it!
This cake was so delicious! Only thing I didn’t like was the eggy taste that comes through. Any substitutions for the egg? Otherwise I will be making this often! Thx
We haven’t tested this recipe with an egg substitute!
Good taste, no outlandish ingredients – everything most people on keto will have. Keto cake just isn’t regular cake – set your expectations for keto and you won’t be disappointed. Topped mine with a little whipped cream – hit the spot!
I’m glad you enjoyed!
Love it! Thank you for this quick and delicious treat.
I’m glad you like it!
Yummy thank you
I’m glad you enjoyed!
This is the first “dessert” I’ve had since starting keto. 5 stars thank you!!
Oh yay! So happy you liked it!
Snicker Doodles are one of my favorites, so I couldn’t wait to try this recipe. It did not disappoint! Yummy
I’m glad you enjoyed!
I truly enjoyed this. Kudos to you??????
I’m so glad you enjoyed!
Love this cake! The fact that it does not call for coconut flour is wonderful! I find it gives everything a “wet” texture. This will be my “go-to” quick recipe when my sweet tooth needs satisfying! Thanks so much for sharing!
I’m so glad you enjoyed!
Can you use stevia as a sugar replacement?
I have not tried but I think that should be fine. You will likely have to reduce the amount used since stevia tends to be a lot sweeter.
I love snickerdoodle cookies and this is a delicious alternative. Thank you!
I’m glad you liked it!
Just made this, Loved it! Only I cooked it in my air fryer 8-10 minutes! Delish
I will have to try it in my air fryer next time!
My 6YO loved this so much she made me come back and give it a 5-star rating! She is right! Clicked to the peanut butter mug cake and loved that too! I already saw several more recipes I can’t wait to try!
Aww, I’m so happy she loved it! Thanks for coming back to leave a rating
I’ve had horrible luck with low carb mug cakes. Got desperate and saw this online. Thought okay I’ll try again…oh my gosh this is so great! Thank you so much!
So happy you enjoyed!
This was such a special recipe for me because I used to make Snickerdoodles for my children. I love the taste and the texture, and it’s rare to find both in a low-carb recipe. Combine that with quick, easy, and made from ingredients that most of us have on hand, and you have a real winner here!
I’m so happy you enjoyed this!
312 calories? WOW! Definitely NOT low carb!
A low carb recipe means it is low in carbohydrates, not calories. This recipe has 4 net carbs.
It is low carb, not low calorie. Maybe know what something means before you diss a recipe for not being it?
