For this keto mug bread, you can make it chocolate or vanilla. All you need to do is omit the cocoa powder from the recipe for a vanilla version that is just as delicious!
You’ll also see in the recipe card below that I provide instructions for almond flour or coconut flour.
I’ve really grown to love coconut flour lately because it is so much more affordable than almond flour. I know some people do not like the taste of coconut flour, so almond flour instructions are provided!
I just love having these easy treat recipes in my back pocket to help me stay on track! You will also love my easy Butter Cookie Energy Bites. They are the most popular recipe on my site! I think everyone loves easy recipes!
Have this keto mug cake with some Keto Coffee!

Made the chocolate cake with coconut flour and microwaved it for 55 seconds and it’s amazingly fluffy and NOT dry! Yay! Thank you for sharing this recipe!
Large amount, easy to make, tastes like chocolate cake! 10/10!
Keto Mug Cake – Chocolate is amazing! Higly recomended.
This cake was really good. I have been craving chocolate. I have only been doing keto for 2 weeks. I made chocolate whip cream to go on top. So good!!
Is powdered swerve ok? That’s all I have 😕
Yes, that will work!
Amazing cake. Thank you
Jennifer,
You’re extra special to me because you were my first!! Lol! My first keto mug cake that is!! It was good and I felt like I was cheating. I posted a pic to my family via text message. I followed your instructions to make it and had great results. I was so proud of the finished product!! Thanks!!
Isn’t 2 tablespoons of swerve erythritol (granulated) 24g net carbs?
erythritol is zero net carbs
The best 60 sec cake ever! Thank you so much for making it simple and so dang tasty.
I wish I could give it more than five stars. This is such a great treat! I added a pinch of salt and some unsweetened coconut chips. So light and fluffy and pure chocolate goodness. Thank you so much for posting this awesome recipe!
OMG! I’ve made mug cakes before, only to throw them out because they were disgusting. This was delicious. My husband loved it and kept saying it can’t be Keto. We shared it, I added freshly whipped cream, no chocolate chips, and cooked it for 50 secs. His birthdays is in a couple weeks, and he said he’d have that en lieu of a full, sugar laden, chocolate cake.
THANK YOU!
Mixed some Pb in it and it was delicious!!
Hi Jennifer. Thks for sharing your recipe for mug cake. I added walnuts to the batter. Delish!!!
I was having a MAJOR chocolate craving and this took care of it. Not only easy, quick but also delicious! Hubby and I shared it as well and I had to prove the carb content because he said it tasted too good to be low carb/Keto! Thanks for posting this and saving me. The struggle is real!
So easy and definitely the best mug cake I have tried! Moist and delicious!
Is the net carbs 3 grams? Or no
yes, 3 net carbs
It came out a little bit salty. I noticed that every time I try one of the cake recipes. Moist though
Amazing. I drizzled ChocZero chocolate sauce on top. This will be my new go-to dessert when I don’t feel like baking.
Hi Jennifer, the chocolate mug cake is fab!!! You are such a good low carb cook. I have recently added 1 tablespoon of sour creme to the mug cake and it makes it super moist. Give it a try!!! Hope u like it!!!
From one low carb sister to another!!!
Oh cook for 90 seconds

First keto recipe ever…wow! Substitutes if dairy is called for? Allergic to cow dairy…thanks.
I am a professed chocoholic. Being new to keto I often crave it. This mug cake is a winner! It was absolutely delicious and worth every star! I used almond flour and so nourished erythritol monk fruit blend. The cake was soft and fluffy. Definitely going in my dessert rotation.
Chaffle are the keto/low carb fad right now. Just made this mug cake with the waffle maker. Enough batter for 2 chaffles. Delicious!
That sounds amazing!
Can you use liquid stevia and if so, how much? New to all this! Thanks!
You can with this recipe but I am not sure on the amount
Delicious! So far this is the best keto mug cake recipe.
My husband and I are OBSESSED with this recipe. Anyone know a way to make a full cake? I’d love to be able to make it for the other Keto girls at work.
