My coconut flour mug cake is the perfect quick dessert for one! You stir it together with a fork straight in the cup. Zap it in the microwave - job done! This dairy-free, sugar free mug cake is moist and fluffy, with a hint of vanilla and a luscious cinnamon swirl.
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 recipe 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.

Ingredients
Here are the ingredients I used:
- Coconut flour - I like the slightly sweet taste of coconut flour. Also, you only need a small amount in recipes, because coconut flour expands so much when you mix it with wet ingredients. This makes it more economical than almond flour. Then there are the numerous health benefits - coconut flour is a nutritious powerhouse! And last but not least, coconut flour is naturally nut free, low carb and gluten-free.
- Sweetener - When I first posted the recipe, I used a powdered erythritol monk fruit blend. I have since made the mug cake with powdered Bocha Sweet and with allulose. 1 tablespoon was just right for me, especially since the cinnamon swirl adds additional sweetness.
- Baking powder - Check that it is fresh, so the cake becomes fluffy.
- Coconut cream - I am using this in place of butter and milk and it makes the cake super moist. You can replace it with heavy cream.
- Egg - Use a room temperature, medium egg if possible. I did try making this recipe with a large egg and found it a bit eggy.
For the cinnamon swirl, I mixed sugar-free syrup with cinnamon. I used the Lakanto maple flavoured syrup, which gives the mug cake a lovely mellow maple flavour. Of course, any sugar free syrup will work.

Instructions
It is easy to make a mug cake with coconut flour. Here are the basic steps. Scroll down to the recipe card for the detailed method and nutrition information.
STEP 1
Measure coconut flour, powdered sweetener and baking powder into a mug. Make sure you break down any lumps.
STEP 2
Add the wet ingredients - coconut cream, a medium egg and vanilla extract.
STEP 3
Stir with a fork until a smooth batter forms.
STEP 4
While the coconut flour absorbs the liquid, prepare the cinnamon syrup. Simply mix sugar free syrup and cinnamon in a separate bowl.
STEP 5
Swirl the cinnamon syrup into the cake batter and microwave until the cake has cooked fully on the top and is starting to release from the sides of the mug.
Katrin's Top Tips
#1 Coconut flour is very absorbent. When measuring coconut flour, level off the flour in the spoon with a knife. If you were to use heaped spoonfuls the cake will end up dry.
#2 It's important that the mug has a volume of at least 200 millilitres. It should also be wide rather tha narrow and tall. Always leave some free space between the batter and the rim. Why? The batter rises as it cooks in the microwave and can spill over if the mug is too small.
#3 As the cake cools it fully releases itself from the edges of the mug and you can turn it upside down 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.
Microwave Timings
Microwaves vary in terms of zapping power. I made 3 different versions of this coconut flour cake in a mug 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.
Here's a quick overview of recommended baking times:
- 900W = 90-100 seconds.
- 1000W = 70-80 seconds.
- 1200W = 50-60 seconds.
Always check the cake 10 seconds before it is finished. If it's still undercooked, add increments of 10 seconds. Also, please keep in mind that cakes continue to bake in the cup after you remove them from the microwave. Don't be tempted to overcook!
Variations
Here are ideas how to tweak the recipe with add-ins or toppings:
- add sugar free chocolate chips or chopped dark chocolate
- throw in a few berries (blueberries or raspberries)
- Stir in a dollop of peanut butter
- Top with sugar free whipped cream
- Slather over a quick cream cheese frosting (cream cheese or mascarpone plus powdered sweetener to taste).
Recipe FAQs
For a sugar free coconut flour mug cake, use erythritol, xylitol, Bocha Sweet or allulose. I used powdered sugar substitute to make the end result smoother, but granulated sweetener would also work. If carbs are not a concern, feel free to use coconut sugar or honey.
If you don't have a sugar free syrup (or regular maple 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.
Sure! You can bake this cake at 180C / 350F (electric) or 160C / 320F (fan-assisted). It should be done in around 12-15 minutes.
I have a great recipe for a moist chocolate coconut mug cake - this keto chocolate mug cake is a coconut flour recipe.
Storage
To be honest, mug cakes are always best enjoyed straight after cooking. And since you can whip one up in a few minutes, there is no real need to make them in advance.
However, in theory you can store this cake as long as any other coconut flour cake: around 4 days in the fridge, if you use an airtight container.
You can also freeze this cake for up to 3 months.

It really IS BEST! So easy to make in minutes and absolutely delicious and satisfying. I once made it with the cinnamon swirl and ended up with a bit of a mess (I simply don't do swirls or any other complicated decorations or procedures ). To avoid disappointment without losing any of the flavour I simply added a bit of cinnamon and a bit of nutmeg to the mix and cooked. It turned out great! Thank you Katrin! Your recipes are brilliant and they always work (in the right hands )!

So happy you enjoyed this one!

Made this delicious mug cake today and it's fantastic! The recipe is spot on as is for a wonderful treat, and honestly it could be for two people if you are willing to share. I will definitely make this again.

Hi Katrin,
Could you explain what 'powdered sweetener' is, please? I live in GB (Britain) so I thought possibly it might be simply good old-fashioned icing sugar, but im really not sure. Although Im dairy, soy and wheat intolerant, I do partake of a little sugar so I dont need to use any alternative or replacement sugars.
Thank you 🙂
Katrin Nürnberger
Just like sugar is available in granulated and powdered form (i.e.icing sugar), so is sweetener.
