Can’t wait to see how wonderfully easy and tasty this will be.
Looks so delicious! Just ordered your Fat Bomb Bible. I always love to support what you guys are doing. I have also purchased DSK and starting it tomorrow. Thx Matt and Megha for putting out such great content for us.
Can substitute something in place of the ground flax meal?
You can use oat fiber or psyllium husk powder as a substitute for the flax.
Would the substitution using psyllium husk powder be 1 for 1?
Thanks!
Thanks… I’d been searching for this recipe for awhile! I’d remembered seeing a variation of this recipe while watching one of your videos [sponsored by a PE Science cinnamon protein powder], but when I finally got the cinnamon protein powder, I couldnt find the recipe, no matter my search method?!?
Nom nom nom! I added a bit of HWC with some powdered erythritol to the top. Melted down into it. Perfect snack for a chilly morning!
Thank you for this recipe this was DELICIOUS! Perfect for a lazy Sunday.
Your hair looks beautiful in this video. I love it down.
Thank you for this recipe, sounds great! I would like to make this tonight but I don’t have flax meal. Can I use Almond flour or psyllium husk? Measurements for either of these ingredients would be amazing! Thank you, love you guys, watch you every day on YouTube!
You could try that! It will be about 3-4 tbsp of almond flour for every tbsp of coconut flour. Let us know if you find a variation! We also have a blueberry muffin in a mug that is made with coconut flour only and that might help you come up with something!
We’re allergic to coconut. If we want to use almond flour as a replacement should it still be a Tablespoon?
Coconut oil is much more absorbent, so it will be about 3-4 tbsp of almond flour for every tbsp of coconut!
about 3-4 tbsp of almond flour for every tbsp of coconut flour.
Can I sub stevia drops for erythritol? If so how much would I need? Thanks!
About a tablespoon! Check to see if it is sweet enough after mixing it in.
Can I use something else instead of golden flax meal – too pricey!
You can use oat fiber or psyllium husk powder as a substitute for the flax.
What can I use to sweeten with besides liquid stevia? I hate the taste. Thanks!
Any sweetener you do like!
Tried these last night super delicious!
The pdf of the cookbook shows 1/2 TABLEspoon of cinnamon, and that’s how I’ve been making it and enjoying it. That’s a big difference for those who are paying attention.
Up in the third paragraph it mentions a “simple mug cake that is low calorie?One scoop protein powder, one large egg, one tbsp butter, and a little baking soda is our main go to.”
It looks like there was supposed to be a link to that lo cal mug cake but the link is not live and I cannot find anything on your site. Was the underlining just that and not a hyperlink? I really would like more info on that recipe. Not sure if all protein powders have the same size scoop or how much baking soda to use.
Thanks!
Replacement for Flax meal? Never sits well with me. Can I do baking soda or powder?
You can use oat fiber or psyllium husk powder as a substitute for the flax meal.
When you bake with butter, are you using salted or unsalted?
We like to use unsalted so we can control the saltiness in the recipe.
I made this last night – wow – super easy and yummy. I ground up some erythritol and dusted the top of the “cake” so so so good. I plan to pre-make the dry ingredients to take to work and make it there. Nice to have with my coffee as the days start to cool down here in Sactown cowtown!
thanks you two – love love love your podcast; youtube; and blogs, the recipes are bomb and although I have not lost but a few pounds, i love how I feel eating Keto way, inflammation at an all time low.
How do you make cream cheese frosting you mentioned ?
Here is the recipe! https://www.ketoconnect.net/simple-cream-cheese-frosting/
Can I sub in oat fiber instead of the flax? Thanks!

Hi!
I can not eat any egg, as it is a trigger for my Spondylarthritis, so I was hopping a recipe variation without egg… Do you have any suggestion to replace egg? Thanks for your help!!
There are “Flax Egg” recipes online you could try out! Just do an online search for one! 🙂
This is super yummy! I’ve made it several times now!
Thank you for the delicious recipe!
I’d like to try this recipe but I don’t want to buy flax meal for one recipe. Can I sub almond flour or tapioca flour? And 1 to 1 ratio? It looks scrumptious! And like Megda, I want an after dinner sweet.
i tried it and it was really good. I would recommend 15 drops of stevia if your eating it as a meal and you want it a little more savory. I did 20 drops and that made it sweeter like more of a dessert.
ISirry for my ignorance but Is the golden flax meal the same as flaxseed meal?
No need to apologize! This isn’t an ignorant question. 🙂 There are two types of flaxseed: regular and golden. (We generally recommend golden because it tastes better. It has more of a toasty flavor as opposed to a more earthy taste that regular flaxseed has.) Both regular and golden flaxseed can be bought as seeds or meal. Meal consists of flaxseeds that have already been ground, making it more convenient for you. However, if you can only find the seed, a coffee grinder can make it meal for you. The nutrition is the same for both regular and golden flaxseed.
Could you substitute the flax meal for flax seed somehow?

Curious if this has an eggy taste like the 60 second bread?
Oh my! Great recipe! Thanx! I will probably cut it into layers sometime in the future and put a little cream cheese frosting between the layers. Will taste like a “naughty” cinnamon roll. Today I ate it for lunch with a little sugar free syrup and whipped HWC. Oh my Lord! Yum!!!
I made two substitutions for this recipe because I didn’t have certain ingredients. I used equal amounts almond flour instead of coconut flour and I used one TBSP Swerve for the stevia. I cooked in microwave for 1 minute and 50 seconds. Came out great!! Thank you Keto Connect for all your awesome recipes!!!!
Hi, can you bake it in the oven also?! if so – do you have any instruction About it?!
Alternatively, you can bake this mug cake in the oven at 350° Fahrenheit for 15 – 20 minutes. Hope that helps! Enjoy! 🙂
Thank you for this recipe! It is saving me from a PMS induced carb binge tonight. Great job guys!
Made this for my family tonight, with 2 tablespoons of the cream cheese icing from your ginger-cake recipe. It was amazing! Keto is easy when you can have something like this on the weekends. My mom is officially off all of her diabetic medication because of keto and your recipe’s make it easy! Thanks guys <3
I just made this and OMG was it delicious!! I dont have any stevia drops so I used 1 tbsp or granular erythritol (like suggested above) and added a little powdered erythritol to the top! Yum!!
I added a little vanilla and made a keto cream cheese frosting. Delish!!!
I tried your simple mugcake “One scoop protein powder, one large egg, one tbsp butter,”
I used IsoPure, i used 1/4 tsp of baking SODA not Powder, and while it was cooking in microwave for 1m i could see the whole cake rising out of the mug lol, i went to taste it and it tasted like cardboard, very dry very dense, not moist at ALL. did i do something wrong? i followed instructions well, please let me know thank you, maybe it shoulda been powder?
Hi Daniel! You should definitely use baking powder, not baking soda. This article explains why. It makes a big difference. Give it another try! 🙂
Ahh ok thanks! You might want to update the top of your page then to powder and not soda :p. Is there also something I can use to make it more moist? I tried it and was better but was still just a little dry
Oh goodness! Thanks for letting us know. I’ve changed that error. I appreciate it!
I’ve made this 3 times since you published on the blog! I have been mixing in cinnamon, nutmeg, cloves and ginger and topping with whipped cream. So good!
So glad you enjoy it!
How many grams of sugar?
We don’t use sugar on keto. You can use whatever sugar substitute you want. You can check out our “Best Sugar Substitute” article and our Low Carb Sweetener Conversion Guide.
Been loving these with my cold brew every morning. They’re great as-is but I’ve gradually been adding more-and-more to the recipe. I figured I’d share my tweaks.
* Bumped the cinnamon up o 1/2 tbsp as another user has suggested.
* Added about a bit of ginger. I’ve been continuing to add more ginger bit-by-bit. I think I’m somewhere around 1/2 tsp?
* Added vanilla extract and occasionally a bit of maple extract to the egg and butter.
* Added about tsp of brown sugar substitute (Sukrin Gold). Used a tad bit less stevia than I did before.
* Added beef gelatin I had left over from the chewy chocolate chip cookies. It quite a game changer– the cakes are so most and soft with it (not to mention the added protein). That said, I still prefer switching back and forth because I like both textures.
* Increased the cooking time to 1:15 – 1:30 due to the extra mass.
I’ve been prepping these for the week and keeping the dry ingredients in small containers. All I’ve got to do is combine the wets and give the drys a little shake before mixing them in.
Thanks for this recipe! I used Aldi’s Simply Nature brand milled flax seed, and about a tablespoon of Swerve. I suspect sugar free chocolate chips would be an amazing addition! [email protected]
What would be the temp and time, if I were to make this in a muffin pan, in the oven?
Maybe 350F until a toothpick inserted comes out clean. I am not exactly sure how long that would take but just keep your eye on it.
Yum! tastes like french toast!
OMG this is so good!! I just ran out of flax so I used almond flour and wow! this is GOOD! Thank you so much for sharing such great recipes with us!
Tried this last night but had a few questions. Do you have to process the flax seed? I’m using the same brand of Golden Flax meal; however, it seemed that it didn’t quite blend in completely. I tasted more flax than cinnamon. I also didn’t have the Stevia drops & I used liquid Truvia & didn’t get it sweet enough. I’ll try again but would appreciate feedback on the flax question. Thanks!
Yes, it needs to be flax meal so that it acts as a sort of flour.
This tastes heavenly with Walden Farms pancake syrup drizzled over it.

I love this recipe so much I want to make a large batch that I can make ahead. Can you turn this into an cupcake recipe to make 12 cupcakes?
You guys are the best,
Shelby
I’m sure you could probably make it work.
For stevia powder instead, about how much do you recommend?
You can use our sweetener conversion chart
Quick,easy tastiness.
Made this evening – used 4 T almond flour instead of flax meal. I didn’t have liquid stevia, so I used 3 tsp granulated stevia. Topped with a pat of butter and a sprinkling of stevia. Turned out great!
Made this tonight, OMG, it is perfect! Love cinnamon!
Not a lot of flavor. Double checked and I totally followed the recipe. Can’t recommend.
I cannot wait to make this recilpe for breakfast. I love all of your recipes thati had tried
This was my first mug cake and it was delish! I have lots of ideas to use this as a base and tweak the flavors! Thanks so much!
Soooo good! Love it with softened cream cheese!
It was very delicious and very moist. I will for sure be making this again and again. Thanks
can you make this without the flaxseed meal?
I’m making several types of mug cakes, thanks to you! Never could bake before 2020, now I’m making Keto meals and healthy meatloafs for me and my dogs. TY so much for your time and trouble to make these great videos thru YouTube!
