This chocolate keto mug cake in the microwave is another one of my favorite quick treats! I give instructions for vanilla and chocolate versions and you can make it with almond flour or coconut flour.
Do you know how much I love my microwave? I am team microwave! Keto Mug Cake is another one of my favorite recipes using that trusty machine!
My 90 second Low Carb Bread is another one of my microwave recipes. So good for sandwiches!
This keto mug cake is so easy to make with only 6 ingredients.
It’s also easy, rich and chocolatey, and ready in under 5 minutes!
For this cake, 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!

OMG…so delicious and not egg tasting. Added a spoonful of peanut butter on to and tasted like a Reese peanut butter chocolate! Thank you, thank you. Carolina

So my 8-year-old sister isn’t doing keto but if she likes something that I’m eating she will eat it! and this was one of them! She took my cake! but I don’t care cause I enjoyed watching her eat happily. This was a good recipe! I baked this instead of microwaving because 1 -I exploded the microwave and 2 – my mom doesn’t want me to use the microwave anymore! (She is a natural doctor)
Zigomango says
This is the best mug cake that I’ve tried making. I laughed with joy when I opened the microwave door and saw how it had risen. Omg. I think next time I’ll take 15-20 seconds off the cooking time and it will be even more delicious! Thank you!!
Sue says
loved it
Oholi Mao says
We tried this, both ways. It is delicious but when we made it Vanilla style, it only rose half as much.
I have trouble with the grainyness of the end result with the coconut flour, but I will persevere and possibly try to grind it finer. Perhaps that will help with the mouth feel, which is the part of the recipe that I don’t like.
Five stars from 3/4 of the family and 4 stars from 1/4

Update :
Making with the almond flour totally is a game changer for me!
We’ve been making this recipe almost daily since my first comment.
Thank you!
Hope Phillips says
Oh my goodness!!!! This was delicious. I had it for breakfast lol
Rose says
Ive tried so many mug cakes. This is by far the yummiest and easiest. Thank you
Beverly says
Hi made the mug cake today for my husbands birthday and it was a hit! The only thing I could not get right was the granular sweetener conversion. I used Splenda Natural Stevia packets that I had on hand and couldn’t figure out how many packets of sweetener to use to make the 2 T on the recipe and cannot find anything online on the packet conversion. Can you help me with that conversion? I kept using packets and pouring until I filled up two tablespoons but seemed like a lot of sweetener! Next time I will purchase loose sweetener.
Charlotte says
I don’t recommend making the vanilla version with coconut flour, It just comes out like a sweet egg. I imagine it would be better with the almond flour so I’ll try that and give my feedback
Juhi says
Wow, this recipe was amazing! My husband just started keto and was craving something sweet. Followed this recipe exactly and it was soft, spongy and yummy!
Michele says
Have been on keto for a year now and this is the FIRST chocolate mug cake I have actually loved! I did use swerve sweetener which I prefer and it came out great. Thank you for the new recipe!
Rhonda says
So delicious! I was craving chocolate and peanut butter. So I made this mug cake and put
natural peanut butter on top. It hit the spot! I like that the calories were reasonable also =)
Cindy Higgins says
Just wow!! This mug cake is super delicious!! Thank you!!
Alicia says
This was delicious! I just began my Keto journey and had a chocolate craving. So happy and inspired by the delicious results. Thank you!
Katie Hurley says
This was amazing. I used erythritol and it worked just as well, and I stuck a half a square of 90% dark chocolate on top that melted as it was warm. Omg heaven. Thank you for this!!
Rachel says
This is an awesome recipe! It will be my go-to for sure. Thank you for sharing!
Shannon says
Jennifer, I literally cannot believe how amazing this is! I added cake batter flavor which took it to a whole new level (if that’s possible!) do you have any idea if this can be converted as a cake or cupcakes baked in an oven with a similar outcome and how I would tweak the recipe? Thank you so much for your work!
Amelia says
****Amazing!!!****
So delicious. I’m new to keto and can’t believe something low carb would taste this good. Thanks for the awesome recipe!
Amelia says
Forgot to mention:
I find that it “bakes” better if you use a wide mouthed coffee cup. I have done both ways, and strongly prefer the wide-mouthed cup.
alyssa baum says
This is also really good with cake batter extract if you’re making vanilla kind (which I found at Walmart) and cream cheese frosting (which I also put the extract in).
Maira Rashid says
You’ve saved my life, I can continue keto with this recipe.
Teech says
My first Keto mug cake and it was DEEEELISH and super easy to make. I added a dollop of whipped cream and wow 🙂 I will definitely make it again. I have a sweet tooth and this satisfies it while staying on Keto..thank you!!
Sherry G Mason says
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!!
