The perfect quick dessert for one! Here's an easy sugar free coconut flour mug cake you stir together with a fork straight in the cup. Zap it in the microwave - job done! This cake is moist and fluffy, with a hint of vanilla and a luscious cinnamon swirl.
You've gotta love microwaves for their ability to produce perfectly formed mini cakes in less than 2 minutes.
Mug cakes are so ridiculously easy to put together. All you need is a couple of spoonfuls of almond or coconut flour, an egg, some liquid/fat, a bit of sweetness and flavouring. Zap it for 90 seconds, and boom - instant pleasure. And sugar free mug cakes... instant guilt-free pleasure!
Now that it's getting colder outside, I find myself reviving my passion for mug cakes in a big way. I've had peanut butter mug cakes, chocolate mug cakes, lemon mug cakes.... and it's not even winter yet 😉
This coconut flour mug cake is so delicious that I had to share it here on the blog. It reminds me of a fluffy cinnamon roll, nestled all easy-going and cosy in your favourite mug.
I love baking with coconut flour - I like its slightly sweet taste and I like the fact that little goes a long way, which makes it more economical than almond flour. And then there are the numerous health benefits - coconut flour is a nutritious powerhouse!
Time to get to the recipe - time is precious and there's a sugar-free cake to microwave!
Instructions
1.) Measure coconut flour, powdered sweetener and baking powder into a mug. Make sure you break down any lumps.
2.) Add your wet ingredients - coconut cream, a medium egg and vanilla extract.
3.) Stir with a fork until you have a smooth batter.
4.) While the coconut flour absorbs the liquid, prepare the cinnamon syrup. Simply mix some sugar free syrup and cinnamon.
5.) Swirl the cinnamon syrup into the cake batter and microwave on high for 90 -100 seconds.
Recipe Notes
- Coconut flour is super absorbent. Make sure that the flour in your spoon is levelled off when you measure it. If you were to use 2 heaped spoonfuls your cake will end up dry.
- I used powdered sweetener in this recipe to make the end result smoother, but granulated sweetener would also work.
- My eggs come from a local farm and tend to be on the smaller side / medium size. If you use a very large egg, I recommend reducing the amount of coconut cream to 3 tbsp. Wait a couple of minutes for the coconut flour to absorb the liquid and see if the consistency looks like in the images above. Add another teaspoon of coconut cream if you feel the batter needs it.
- Microwaves can vary in terms of zapping power. I made 3 different versions of this coconut flour mug cake and found that for me, 100 seconds was perfect. Start off with 90 seconds and see if you need to tag on another 10 seconds yourself. I'd say that 2 minutes is the maximum though. Any more and your cake will dry out too much.
- As the cake cools it releases itself from the edges of the mug and you'll be able to turn it out onto a plate. Don't attempt to do this while it's still hot - it's still fragile then and might break. I ate mine straight from the cup.
The cinnamon swirl - tips and tricks
I used the Lakanto maple flavoured syrup, which is made with erythritol and monkfruit and gives the mug cake a lovely mellow maple flavour. Of course, any sugar free syrup will work.
If you don't have a sugar free syrup to hand, melt 1 tablespoon of butter and add 1 teaspoon of powdered sweetener plus 1 teaspoon of cinnamon. For a dairy free version, use coconut oil instead of the butter.
Toppings
To push the boat out, you can top the cake with a cream cheese frosting (cream cheese or mascarpone plus a bit of powdered sweetener).
Can you bake it in the oven?
Sure! Try 170 Celsius / 350 Fahrenheit for around 12-15 minutes. (NOTE - I have not tried this myself, but that's the temperature and time I would go for.)

Is the coconut cream like the little cartons you add to curry?
Katrin Nürnberger
Yes, you can buy coconut cream in cartons.

I don’t use a microwave. Do you know what time and temp in conventional oven?
Katrin Nürnberger
I would go for 180C electric or 160C fan and around 15 minutes, then check for doneness.
Naomi A Jones
I made this but subbed lemon extract for the vanilla and left out the cinnamon and syrup, sprinkled brown sugar substitute on top. Delish!
Eliana Ramirez
I loved this recipe!! It was very easy to make and I could not believe my cakes were all fluffy, soft and delicious!
Cal
Just love the simplicity of your recipes. As a diabetic you have helped me so much. Many thanks, Cal
Lorraine
Tasty treat and easy! Didn't stick to cup at all, thank you!
LORRAINE
Excellent! I had to use canned coconut milk but it came out great. I only use coconut flour so I appreciate these.
Betina
Excellent!

Oh my, saw this late last night but was too tired to try it. Am getting ready to make it. I'm assuming the vanilla is added to cake batter in step 2, not the syrup? Will def rate this later as I'm a big fan of mug cakes and store brands, even keto friendly, don't cut it. Have to admit I loved those store brands with sugar before starting this lifestyle.

Is it possible to use applesauce as a sweetner. I don't use any sweetener at all.
Katrin Nürnberger
Yes, that will probably work.

I love your recipes but being an Aussie, I'm not sure about the mug sizes and microwave wattage that you use.
How much water would the mug hold if it was full... and what wattage is the microwave...1000 watts, 1100 watts, 1200 watts?
Also at the moment we don't have available the powdered sweetener you use. What can I substitute.
Thanks
Win
Katrin Nürnberger
My microwave is 900 watts. If yours is stronger, you'll have to reduce the cooking time.
The mug I used for this recipe holds 200 ml.
As for the sweetener, for this recipe you can use granulated sweetener as well. To make your own powdered sweetener, just blitz some granulated in a food processor. I do that when I have run out!

Thanks for your reply.. I accidentally combined questions for 2 separate recipes... lol..
My question about the sweetner was actually about the golden erythritol and monk fruit sweetener used in the Coconut Flour Cookies. I have erythritol and I see that the local supermarket now carries a Stevia brown sugar substitute. Can I use that by itself or should I make a mix of it and the erythritol?
re the microwave wattage... thank you. My microwave is 1100 watts but the medium high setting is equal to 800 watts. Would I be better to use the full power for a shorter time, or use the lower power for slightly longer? I guess it will be trial and error. I am a beginner at Keto and want to get it right or my husband won't eat it..
Thanks again
Win

Hi Win, if it's a 1:1 sugar substitute you can use is in the same amounts as long as you measure in cups and tbsp. Sometimes, stevia sweeteners are lighter in weight so don't measure in grams.
Regarding the microwave, I think both would work as you describe. Maybe the lower wattage will give a more even bake (but just guessing here!).
