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!
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

Chaffle are the keto/low carb fad right now. Just made this mug cake with the waffle maker. Enough batter for 2 chaffles. Delicious!
Dee21 says
Delicious! So far this is the best keto mug cake recipe.
Robyn says
I was craving something chocolates, only to realize that I gave no cocoa powder. Instead, I made the vanilla version and used Coconut flour and brown sugar Swerve. Took 1 minute 30 seconds in my microwave. Wow! This combination tasted just like French toast. Next time, I will be more heavy handed on the vanilla and less so on the Swerve.
Kapri says
I've tried a lot of keto mug cakes and they all tasted dry, eggy or undercooked. This by far was the BEST one and I actually ate the whole thing. I did ass some vanilla extract and don't skip adding lily chocolate chips I think that's what took it over the top and made it super delicious. I also used coconut flour instead of almond I think that makes a difference as well. Almond flour seems to be more grainy and the texture is off.
Jill Roberts says
That keto mug cake looks absolutely fantastic. Beautiful photos, too. I look forward to trying this. Thanks, Jennifer
Stephanie says
I’ve made this 3 nights in a row and made it for a friend as well, and she loved it. Even if I ever quit keto, I’ll still be making this one!
Kim says
I made the chocolate one for my husband (sprinkled a few Lily’s chips on top). I made myself the vanilla (topped with ChocZero caramel sauce). Both were cake like, not dry and delicious. Definitely satisfied our sweet tooth. I will definitely play around with this by adding lemon/blueberry to the vanilla. Endless possibilities! Thank you so much for this awesome recipe!
Andrea says
After bad experience using the coconut flour for mug bread (I obviously must have done something wrong) I thank you for this great recipe to help my chocolate cravings. I topped it with syrup, perfect!!!
Reese says
Mine came out pretty dry but otherwise okay. It had more of a bread texture than a brownie texture. Maybe my microwave was too strong. I used a glass coffee mug and cooked for exactly 1 minute.
Jenna says
This is delicious!! Thank you so much! ❤️
Peggi says
I was just hungry for cake tonight. We are house sitting for friends and not in our state even. They don’t have a microwave and I couldn’t find a ramekin to bake this in. But I did fine a tiered cake pan set so used the smallest. I only had almond flour so used that. I didn’t spread the batter and put it in before it had reached temp (probably around 275), baked for 20 mi utes and it was great! I did put SF. No Olathe. Hips on top AND some nuts. Yum!!!
S says
Great recipe
Elizabeth says
3 star rating because my mug cake was dry but I really enjoyed the recipe. I am going to try it again maybe I Microwaved it for too long but I still like it.
Kelly says
Had a sweet tooth and been on keto for over a month. Just tried this ( cocoa version) and OMG it was delicious!!! My 15 year old,son had a taste after walking through the house trying to find the chocolate smell!..lol
Brittney says
For a cake made in 60 seconds in the microwave that was pretty fricken good. I used 1 tbsp of stevia and it was the right amount of sweetness when chocolate chips were added. Nice moist cake, will have again. Thx
Shellie says
I’ve died and gone to heaven. So good. I used almond flower instead of coconut flour. Came out moist and even my picky husband asked for a bite and loved it. Thank you for the recipe.
Elle says
OMG!!! This is by far, the best mug cake that I have ever tasted! I just made the vanilla one, because I don't have any more cocoa powder (crazy, I know). It is so moist and flavorful! I may have added more than a splash of vanilla...and I may have poured a drizzle of a coconut oil/Swerve/coconut milk glaze on top. 🙂
Cece says
Made this tonight, AMAZING! Very delicious and satisfying. Are the 7.5 carbs total or net carbs though? Either way, YUM!
Donna says
5 STAR Rating!
My first time with Keto dessert!
Wonderful, just added my pecan~
Thanks!
Meredith says
Love this recipe! I put all of the dry ingredients into a snack size zipper bag, made about 20 bags, put them all in a gallon size bag, wrote the instructions on the outside of the gallon bag (add egg, vanilla, oil, etc.), and put them all in the freezer. My kids pull one out whenever they want! I reduced the erythritol to 1 TBSP (I don't like it so sweet), and sub avocado oil for the butter. I top the vanilla cake with a few blueberries or a couple of strawberries, very satisfying!
Jenny says
It’s simple and tastes great!
Deirdre says
Omg thank you! First real cake I've had in over a month and can't believe it's low carb. Just a tad too eggy but no big deal. First time I used Swerve or almond flour and wow!
Amy C says
OMG this is amazing!!! I made it with almond flour and monk fruit sweetener and this is sooooo good!! Thank you for the recipe!
Brianna F says
I was so skeptical while reading the comments on how good it was, because everything I make with almond and/ or coconut flour always turned out mushy or heavy. But this, definitely did not disappoint. I prefer almond to coconut flour because of how absorbent coconut flour is, so that’s what I used. This mug cake didn’t taste keto, amazing recipe.
Nicole Konecny says
This was a perfect little satisfying treat for my husband and I. Pleasantly surprised.
Nina says
Loved it.
Emily C says
Really tasty. I've made this a few times and I can't believe I'm saying this, but I enjoyed it more with just one tablespoon of sweetener versus two (!! What's happening to me?) And a tablespoon of peanut butter. Anyone who's thinking of making this, it can go from raw batter to dry in a matter of SECONDS so keep a close eye on things. I'm amazed at how filling it is... could barely finish. I can eat entire ordinary cakes. 🙂
Kerry says
Ummmm I love you thank you for this recipe that finally tastes like a brownie
René says
Delicious! I love this! Thank you for sharing.
Kel says
This is one of the best mug cakes I’ve had. And it’s Keto Friendly! I add a homemade chocolate sauce to moisten it up and it’s delicious. I’m also surprised at how filling it is. I’m lucky to make it through one half. Thank you!
Jen says
I have made one the last three days with a dollop of Choc Zero on top. This may be THE ticket to keep me on keto and not feel deprived. I've tried other low keto mug recipes and this is by far the best. Thank you!
Renee says
Fixed this recipe tonight, just to have something other than cream cheese fluff and blackberries. I'm not keto, but low carb. This was a very satisfying dessert. My teenager and I split 1/2 and the rest for tomorrow. Thank you for a quick, tasty treat.
Laura says
Thank you!! This was great. Although in my haste to make it I forgot to add in the baking powder! I used almond flour but plan to buy coconut flour and remember to add in the baking powder next time 🙂
veronica says
OMG!! Ive been keto for 3 months and this is the first time I write a review for anything! This has been the ONLY recipe that has created for me something great with the macros that actually taste like it belongs outside of keto because of how delicious, moist, tender, light and just flat out PERFECT! And also, mega plus, SO SIMPLE! Thank you!!
Tabs says
I added a small spoon of peanut butter and swirled it around in the batter and it was amazing. I topped it with a sprinkle of chocolate chips while it was still warm so they would melt on top and topped with whipped cream. So delicious!
Nancy says
I’ve tried a ton of these looking for the best one. Well this is it! Yummy and EASY! Thank you!!
Denise Freitas says
Craving sweet so day. Had all ingredients on hand so I just made 2 for me & my husband. Delish! I made thr choc version with coconut flour & sukrin:1. Added a splash of vanilla because vanilla helps everything. I'll be making this often.
Murtsource says
My first keto desert, as well as my first ever "mug cake" made in a microwave! It was delicious! Reminded me of those steamed puddings that you find in England. I didn't have Swerve, just pure erythritol I ordered from Germany, but it worked just perfectly. I used the full 200 gm measurement, and I think the next time I make this I will use less, because it was super sweet. I also didn't have coconut flour, so I used almond flour. Two thumbs up.
Andy says
Fabulous!
Cora says
I have tried several mug cake recipes and was not impressed. This recipe is a keeper! So far I have used coconut flour only. I have made the chocolate (I don't have chocolate chips), but good without them! Tonight I made the vanilla, but added 1/4 tsp ceylon cinnamon. Yum!!!
Jessica says
This is the best keto cake/brownie recipe EVER. I made it with almond flour. I've tried so many and either the cocoa, erythritol or almond flour was over powering. This was perfect! New go-to chocolate sweet tooth fix! Thank you!
