Sweet mug cakes are some of the easiest go-to keto desserts. A couple of minutes - that's all it takes to make this treat! Even if you don't follow a ketogenic diet, you will simply fall in love with them. Just like my other recipes, these are also paleo-friendly. If you don't have a sweet tooth, you can try some of the savoury mug muffins on my blog!

Ingredients (makes 1 serving)

Tips for substitutions: If you want to make the recipe nut-free, use 1 tablespoon of coconut flour instead of 2 tablespoons of almond flour. If you don't have coconut flour, you can use 2 tablespoons of finely shredded desiccated coconut instead.

Too "eggy"? Although I like this combination, some of you may perceive it as too "eggy". You can try the following: use one egg, double all the dry ingredients and add 1/4 cup coconut milk, almond milk or cream. This mixture will make 2 mug cakes. Instead of the listed sweeteners, you can try other healthy low-carb sweeteners from this list. The reason I'm using both Erythritol and stevia is to mask the aftertaste some of the sweeteners may have.

I changed the way I ate in 2011, when I was diagnosed with Hashimoto’s, an autoimmune disease that affects the thyroid. I had no energy, and I found it more and more difficult to maintain a healthy weight.

That’s when I decided to quit sugar, grains, and processed foods, and to start following a whole-foods-based ketogenic approach to food.

Thank you for the recipe and your tips at the end!! I made this last night with the 1 tablespoon of coconut flour, butter, and added a splash of heavy whipping cream bcuz mine seemed to need more liquid. Probably bcuz coconut flour is so absorbent. Anyway, it was delicious!!! Because of recipes like this, Im not missing sugar at all. Thanks again!! Love it!

I'm glad you enjoyed!

I'm not sure what I did wrong. I've made mug cakes in the past, but this one turned out really thick (like a dough, not batter). I did not add liquid stevia as it said optional.

Reply

Hi Christina, did you substitute the almond flour with coconut flour (more absorbent)? That might be the reason. Or the egg might have been "medium"?

Reply

I added lots of vanilla and a 1/8 or so of a cup of Lily's chocolate chips. Very tasty! Mine was a bit dry and crumbly, I think I used too much 'heaping' in the tbsps and not enough olive oil.
I'll attempt to do a bit more with it in future. It stands on its own, and is also such a great base recipe; I'll try adding lemon or orange extract and perhaps  some berries and/or nuts (though will try the chocolate chips again with the lemon...lemon and chocolate!! ...and also with poppyseed. Lemon poppyseed are my favourite muffins).
Thanks for the recipe for this versatile mug cake!

That might be the reason - it is always best to go by "grams/oz". I love using this as a base for quick deserts! 😊 You may like these:

Need to recalculate. This is 8 net carbs

Kris, I suppose you use an app like MFP to get to that value? I'm afraid your calculations are wrong. We use verified sources (not crowd sourced) to calculate all nutrition facts. What you see is accurate.

Mine was a complete bust. Followed the directions minus the sweetener mentioned and it smells like straight eggs andlooks nothing like the pic.

Hi Melissa, I'm sorry it didn't work for you. I've been making this mug cake for several years and always had the same results so I'm not sure what the issue might have been. There are tips below the list of ingredients that might help.

How many calories???

Reply

It's listed in the table as "kcal".

Are we to use both the almond flour and the coconut flour or just choose one or the other.   The ingredients listed both but the tip said to use 1 tbsp of coconut flour instead of almond flour.  Would that mean we are to 2 tbsp of coconut flour?  
Also, your recipes look delicious.  Looking forward to giving this one a shot as well as a few others.  

Reply

This recipe uses both but if you want to avoid almond flour, you can substitute it with a tablespoon of coconut flour. I hope this helps!

We made these the other night. First dessert in a month after starting Keto. It was delicious❤
We topped it with a few diced strawberries and a little sugar free whipping

Simple, quick, and delicious! My husband and I split one with some Halo Top ... Thanks for the recipe! This will certainly be one I make again!

Reply

Thanks for the recipe! I added 1 tbsp unsweetened cocoa powder and oh man it was so freakin' good! (I did butter, powdered erythritol, and 3 drops of liquid stevia). Would be super good with a scoop of vanilla halo top!

Reply

I tried this tonight and unfortunately, my batter came out super thick.  Are the proportions on the recipe correct?

Reply

Hi Scott, I'm not sure what went wrong. It's very small amounts so you shouldn't need to weigh it. Did you use large eggs?

Reply

I had the same issue...  I think "heaping" is a subjective term ...different ppl use it differently. A suggestion... would it not be easier to measure in tbsp and teaspoons...I read somewhere that a tbsp each of almond flour and coconut flour each weigh 6gms and 8 gms respectively..heaping more may have caused thick batter.

Could you double/triple for an actual cake? It tastes so good!

Reply

Absolutely! I'm glad you like it 😊

This saved me from my daughter's graduation cake left overs!! I was seriously debating going off plan and just smashing the cake, but I found this instead! Delicious!! Thank you.

I've tried a lot of keto mug cakes and this one is definitely in my top 3. I was really excited to try a vanilla base cake since almost all of the other ones I had tried in the past were chocolate.  I knew I could make a few tweaks to the flavor without changing much of the integrity, and I'm really glad I did.  Instead of using vanilla extract (1/2 tsp in recipe), I used a combination of Sugar Free Vanilla Torani Syrup (1/2 tsp) and Sugar Free Chocolate Chip Cookie Dough Torani Syrup (1 tsp).  (I skipped the liquid stevia entirely since I added in the extra syrup.)  I let the mixture sit for a few seconds and then added in 1 tbsp of water to thin the batter.  90 seconds in the microwave and it was perfect.

Torani makes SF cookie dough syrup?  You may have changed my life with this info, friend!  Yay!

My first experience with a keto dessert fell flat so I was skeptical of the mug cake but we're having a celebratory cake at work tomorrow so I really wanted something sweet. I made this to try tonight and holy moly it was fantastic!!!! I used Monkfruit as my sweetener and didn't bother to top it with anything! Thanks! I am totally going to stalk the recipe pages now!

Hi Martina! I love your blog and have been reading and following it for a while. I started a keto diet a while ago and lost almost 30 pounds but I fell off and trying to get back into it. Unfortunately when I fell off I was eating sweets again. Now that I'm trying to be strict with keto again I am craving sweet food so I decided to try some of the mug cakes and made this vanilla one tonight. It was really good and stopped me from buying something with real sugar today. I also made the bone broth and chicken broccoli alfredo yesterday and it taste great. Your blog is really helpful with many different food and drink options to never get tired of. Thanks!

Thank you so much, I'm glad that my keto treats help you with sugar cravings! 😊

I just made this and it was fantastic! Try it, you will love it.
I added 1T cocoa powder and a 1t extra swerve. I also measured the flours.
Thank you!!!

Thank you Terrie, I'm glad you like it!

I was having a sweet craving just now and this is bomb.
The mixture looked a bit dry to me so I added half a tablespoon of heavy cream and the cake was moisture, fluffy and delicious!
Thank you for the amazing recipe!

Thank you Paula!

I added some dairy free chocolate chips and topped with whipped coconut cream. Ah-mazing!!

Reply

Thank you! 😊

Quick clarification - the recipe as is calls for 1T coconut flour and 2T almond flour - so if I go nut-free it would be 2T coconut flour total, correct?  the original 1T + the replacement 1T.

Reply

Hi Lisa, yes that's correct - just make sure these are "heaping" tablespoons. I hope this helps!

Reply

Thank you for this recipe! It was yummy! I have a question though: is it normal for the bottom portion to have a blue tint to it? I used coconut flour,butter, and truvia. Not sure if that had anything to do with it?

Reply

I'm not sure to be honest - could it be the almond flour or sweetener? I never noticed that!

Reply

I sometimes get a blue tint on the keto buns. But I only get it when I make a whole loaf instead of the buns. Weird!
