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 have to add my vote! I have tried several keto mug cake recipes and they were ALL dry! This one is not. It smelled a little eggy when it was cooking but does not taste eggy. I made the chocolate with the almond flour and I will be making this again….and again….it is the absolute best! Not dry and a few Lily’s chocolate chips made it decadent.
Britt says
Oh my freaking god, this recipe is AMAZING. Discovered it last week as me, my wife, and my dad recently went keto. I was craving something sweet, so we made 1 mug to share. It was so good that I printed out the recipe (which I haven’t done for years) and stuck it on the fridge. 6/5, really a home run and so easy!
We made it with coconut flour and it turned out excellent. We have made it 3 times since then. I put a dollop of peanut butter in the last time, and it was great!
Tip for anyone reading: be careful to thoroughly combine the ingredients…on time 3 of making the cake, there was a little pocket of scrambled egg which was 100% my fault for not mixing properly.
Kiki says
I have tried every mug cake out there and is IT!! 10/10! My husband couldn’t believe it was keto, and ate more than me! Thanks so much
Terri says
OMG I was sitting here dying for something sweet and “cakey” dreading yet another icky dry eggy so called bread or cake. I made this with almond flour (cannot stand coconut flour!) and threw a few sugar free white chocolate chips on top and I am in absolute HEAVEN!! Came out very moist and absolutely DELICIOUS!!! THANK YOU!!!
Shirley says
Made the chocolate version for my diabetic husband’s birthday. Very delicious and moist! Would there be a way to make a lemon version?
Terri says
Maybe leave out chocolate as in the vanilla directions and add a few drops of lemon extract? Might also add just a little vanilla. This is such an easy recipe it might be worth a try.
Angela Reiter says
This is awesome. Yummy taste, quick and easy. Hits that chocolate craving. Thank you.
Theresa says
Thanks for sharing the best mug cake recipe ever
Liz says
I tweaked the recipe to make a pumpkin spice version for fall. I replaced the cocoa powder with pumpkin pie spice and added three small dollops of cream cheese sweetened with the Swerve sugar, microwaved it for 1:30 minutes, and topped it with cinnamon and Swerve sugar. So good and a great way to get pumpkin spice in a keto way.
Jess says
Best vanilla mug cake I’ve made thus far! Can I add a Tablespoon of coconut flour and subtract a tablespoon of swerve? I had a little bit of an aftertaste that was not terrible but if I could lessen it, it would be perfection!
Kristin says
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!
Lauren Michaels says
first coconut flour mug cake ive made and actually liked!!
Emily Schmidt says
Large amount, easy to make, tastes like chocolate cake! 10/10!
Angelina Paunovic says
Keto Mug Cake – Chocolate is amazing! Higly recomended.
alcooks says
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!!
Brittany says
Is powdered swerve ok? That’s all I have 😕
jenniferbanz says
Yes, that will work!
Grace says
Amazing cake. Thank you
Ester says
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!!
Nathalie says
Isn’t 2 tablespoons of swerve erythritol (granulated) 24g net carbs?
jenniferbanz says
erythritol is zero net carbs
Melissa says
The bag of granulated erythritol i have says 4g Carbs per teaspoon. This would make it 24g carbs for 2 tablespoons (3 tspns =1 tblspn).
Maybe the powder erythritol is different?
jenniferbanz says
erythritol is a sugar alcohol and the carbs are subtracted
Melinda says
The best 60 sec cake ever! Thank you so much for making it simple and so dang tasty.
Susan says
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!
S. says
Tried the coconut flour version and it was good! Reduced the sugar to 1 tbsp instead and drizzled some lakanto maple syrup instead. Easy and yummy recipe!
Waynonda says
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!
Sarah E Miller says
Mixed some Pb in it and it was delicious!!
Margo T says
Hi Jennifer. Thks for sharing your recipe for mug cake. I added walnuts to the batter. Delish!!!
Libby says
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!
Tonia says
So easy and definitely the best mug cake I have tried! Moist and delicious!
Roxanne Rougier says
Is the net carbs 3 grams? Or no
jenniferbanz says
yes, 3 net carbs
Liam says
It came out a little bit salty. I noticed that every time I try one of the cake recipes. Moist though
Rima says
Amazing. I drizzled ChocZero chocolate sauce on top. This will be my new go-to dessert when I don’t feel like baking.
MargoT says
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

Najmun says
It’s amazing and tasty than plain almond cake and it has no egg smell
Bev says
First keto recipe ever…wow! Substitutes if dairy is called for? Allergic to cow dairy…thanks.
Tonia says
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.
JENNIFER SIERRA says
My first keto mug cake and it was so easy and delicious! Made it with almond flour and granulated swerve, next time I’ll add walnuts. Thank you so much for satisfying my chocolate craving!
Robyn M says
Chaffle are the keto/low carb fad right now. Just made this mug cake with the waffle maker. Enough batter for 2 chaffles. Delicious!
jenniferbanz says
That sounds amazing!
Marlene says
Can you use liquid stevia and if so, how much? New to all this! Thanks!
jenniferbanz says
You can with this recipe but I am not sure on the amount
Dee21 says
Delicious! So far this is the best keto mug cake recipe.
Janna says
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.
