Absolutely fab, just used stevia sweetener about 3/4 of a Tbsp and almond flour and put in the microwave for 50 seconds . It was absolutely delicious served with plain yoghurt
Helen says
Just made this, with almond flour, and it is delicious! I also added some peanut butter and dark chocolate pieces on top. Totally scrummy! Cooked it for one minute and was nice and light. Other recipes I’ve tried have been a bit rubbery. Not this one!??
Thanks so much?
Stephanie says
This was the BEST keto mug cake I have tried! I used almond flour and swerve for the sweetener and cooked for 55 seconds and it was perfect! Thank you for sharing.
Janet Richter says
Excellent, excellent. Made it with the coconut flour. Love it. Thank you for the recipe.
Fran Sparks says
I made the chocolate mug cake. Splurged and added a little Kaulua to soak in and topped with whipped cream...yum
Debi says
This was lovely! Once it as done I put a couple of choc chips on top as suggested, flipped upside down into a bowl and pushed a small square of chocolate into the top.
Add a drop of hwc and it was bliss! Yum. Thank you x
Kim says
Oh boy Jennifer, I make this way too often!! I use almond flour and throw a couple small dark chocolate squares on top before cooking, they sink to the middle for even more deliciousness. This cake is quick, very moist and yummy.
ATUSA says
Just made it. Finally! Something that fools my brain into thinking it’s eating chocolate cake! Totally hits the spot.

It was easy to make, took less than 10 min and unfortunately... now I want more ?

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!!
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
Oholi Mao says
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
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!
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.
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!!!
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.
Grace says
Amazing cake. Thank you
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!!
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!!
Emily Schmidt says
Large amount, easy to make, tastes like chocolate cake! 10/10!
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!!
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!
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!
