This coconut flavored cake is moist and fluffy. It is an easy low carb, keto-friendly cake that cooks in the microwave in less than 2 minutes.
This cake makes an easy snack or dessert when you’re craving something sweet. I love how light, fluffy and moist the cake is.
Ingredients
- Butter
- Coconut Flour
- Baking Powder
- Egg
- Erythritol granular
- Milk
- Shredded Coconut
How to Make A Keto Coconut Mug Cake
- All the ingredients except the shredded coconut are whisked together until smooth. Then, the shredded coconut is stirred in.
- The cake is cooked for about 1 minute and 30 seconds in the microwave or until fully cooked.
- I recommend topping the cake with coconut whipped cream or regular whipped cream before serving.
Tips for Cooking this Mug Cake
- This mug cake is meant to be a single serving, so it will just fill an 8 oz mug. However, it does rise quite high when it cooks, so it should be cooked in an oversized mug.
- If you want a nice presentation, cook it in the larger mug and then replate it in an 8 oz mug.
- You can replace erythritol with Swerve or another similar low carb granular sweetener.
- You do not need to grease the mug. The cake will pull away from the sides when it is finished cooking.

Keto Coconut Mug Cake
This easy coconut mug cake is fluffy and moist. It cooks in the microwave in less than 2 minutes.
Ingredients
- 1 tbsp unsalted butter melted
- 2 tbsp coconut flour
- 1/4 tsp baking powder
- 1 large egg
- 1 tbsp granular erythritol
- 2 tbsp milk can use coconut, almond or regular
- 1/2 tbsp shredded unsweetened coconut
Instructions
- In a large microwave-safe mug, add all ingredients except shredded coconut. Mix with a small whisk until batter is smooth and egg has been completely beaten in.
- Stir in 1 tbsp of shredded coconut.
- Cook cake in microwave at full power for about 1 minute 30 seconds or until cake is fully cooked. Cake will initially rise very high before sinking back down when it stops cooking.
- Allow cake to cool a few minutes before eating. If you want a nicer presentation, you can remove the cake from the large mug and place it into an 8 oz mug. Top with whipped cream or coconut whipped cream before serving.
Notes
- The cake can be topped with regular whipped cream sweetened with erythritol or coconut whipped cream (replace the powdered sugar with powdered erythritol)
- I used So Nourished erythritol sweetener granular* in the cake.
- I used Bob Red Mill's coconut flour.*
- I cooked my cake in an 1100 watt microwave. You may need to adjust time and/or power if you are using a different wattage.

Did you make this recipe?I'd love to see it! Mention @KirbieCravings and tag #kirbiecravings!
Absolutely loved this, thank-you for sharing. I added a little vanilla and left out the coconut.
So glad you enjoyed it!
I doubled the recipe and made it in a 6 inch round pyrex and it turned out perfectly. I cooked it for 2 mins in the microwave and then melted sugar free chocolate chips on the top. I halved it and shared it with my partner. It made quite a lot. I was pleasantly surprised. I could have quartered it and saved some for later.
Thanks for sharing your adjustments!
I did similar…making 2 at a time in a 7 inch round pan for 2 minutes, makes it thinner which you can pick up a slice and eat.
Taste is good, texture is very grainy
That’s strange – did you stir the batter until it was smooth?
I have found that graininess can depend on the brand of coconut four you use. Some are grainier than others.
Thanks for sharing that tip!
Sorry I’m the only one that didn’t like it but I just tried this because I’m a fairly new type 2 diabetic. I’m a sweetaholic but this wasn’t what I had hoped for.
We’re sorry it didn’t work for you.
YUMMM! My family had angel food cake at brunch and I subbed my cake for this, it was perfect. I omitted the coconut and added a tsp of vanilla and topped with keto strawberry sauce and sf whip ?
I’m so glad you enjoyed!
I just made this pretty much as the recipe is stated, substituting ghee for butter an added quarter teaspoon of lemon extract. This was really really good! Thanks so much!
I’m so glad you liked it!
Delicious!!
Not really a fan of microwave cake since it usually turns out soooo dry.
But this one was really moist and fluffy.
Great for a craving and not too sweet.
I’m so glad you liked it!
I’ve tried several mug cakes in the past to get my cake fix and your keto coconut mug cake blows all of the rest out of the water! I’ve had a craving for coconut cake for quite a while. So glad that I found your recipe. I will be trying your other keto mug cake recipes as well. Thank you for sharing your recipes! Much appreciated!
Thank you for the kind words! I’m so glad you enjoyed!
Loved it. On keto for 2 month and needed a cake fix. This was so yummy did nit feel like cheating anymore.
I’m so glad it worked out well for you!
It was yummy and easy to make. Served it with a heap of heavy whipping cream and powdered swerve whipped to stiff peaks
I’m so glad you liked it!
Great taste and texture. Super quick.
I’m glad you liked it!
I’m addicted to this now! Yummy as is. I tried adding a 1/4 cup of frozen blueberries and it was yummy! Adds carbs tho.
I’m glad you liked it!
Great and easy recipe! I needed a quick dessert fix and this recipe made the mark! Its delicious! Thank you!
I’m so glad you enjoyed!
I followed the recipe exactly, but my batter was dry and crumbly, and Im not sure that the cake rose. Any ideas?
it sounds like you have too much coconut flour. Coconut flour is very absorbent so you need to make sure you don’t go over the specified amount and that you include all the liquids in the recipe to allow the coconut flour to absorb
Loved it. It’s delicate and just sweet enough. Thanks, I will be making this again and again!
So happy you liked it!
Super easy and so delicious!
Yay! Glad you liked it!
Hi, do you think this can be baked As mini muffins in the toaster oven? And do u think I can sub regular sugar? My daughter is doing allergy treatment and needs to dose coconut and eggs so I think this recipe would be perfect for her except she’s not too keen on the texture of mug cakes when it cools but can’t eat it fast enough while it’s warm. Thanks so much.
Yes you can sub regular sugar. I have not tested this in a toaster oven so I’m not sure how well it will work.
