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!
jenniferbanz says
so happy to hear that!
Mischa Galenkamp says
It turned out really salt, how is that possible?
jenniferbanz says
I’m not sure as the recipes doesn’t have any salt.
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!!!
Nette says
Hi! I have been searching for a good mug cake recipe and this is it! I have tried a couple others, but they used almond flour. I had not used one with coconut flour and this one is awesome! I will use this as my go to recipe when I get a chocolate craving for now on. Also I did not have swerve so I used pyure sweetener. I only used about a tablespoon and it was perfectly sweetened! Thanks for the recipe.
Alexa says
This was awful I made and it was dry and burnt on the outside but the inside was gory and raw I followed the exact recipe and it didn’t work after multiple attempts
Sam says
It was likely the mug. I used a glass mug. 1$ purchase at Dollar store! Give it another try! I just fell in love with what tasted like real yellow cake!
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
Marvin Jones says
I made the mug cake with coconut flour but I used monk fruit -stevia blend 1 and half tablespoon and 1 tablespoon chocolate protien powder for the cocoa and threw in some chips about tablespoon and it turned out really good.
S says
Great recipe
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!
Wanda says
I made this tonight and it was so good I took zippered sandwich bags and wrote how much dry ingredients and Add 1 TBSP melted butter and 1 beaten egg. Zap 1 minute. I now have two little baggies sitting on the shelf where white flour cake mixes sat. Now when I have the munchies, I can have cake almost instantly.
I did add 1 tbsp chopped walnuts to the baggies for next time.
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
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.
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.
Mike says
Could I make this and keep it in the fridge or in a cooler of ice for a few days? I love eating this in the evening but I’m going camping for a few days without modern baking appliances.
jenniferbanz says
I think that would work!
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!
Marissa Echevarria says
Wow! Just made the chocolate version with coconut flour. I tried to use liquid Stevia but did not get the conversion quite right, so it was not sweet enough. But then I just poured a little Lakanto sugar-free maple syrup on top and it was delicious! So easy and yummy. Thanks, Jennifer! Looking forward to trying out other recipes on your site.
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!
Fadzai Cruz says
absolutely yummy!!!
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!
Tiffany says
I made this but it really needed something so I split the extract, 1/2 lemon & 1/2 vanilla, added chopped pecans and a small amount of sugar free choc. chips. This made them stand out! I may try coconut flour instead of almond flour because it’s less grainy in texture, but nice base recipe, really like them!
Dee says
I wonder if just the egg yolk would make it taste less eggy.
jenniferbanz says
You would want to do just an egg white as the eggy taste comes from the yolk
Kay says
Loved it! Stuck to the recipe (for coconut flour) but added 1 T of heavy cream, (just cuz it was about to expire!) and used 1 T of Pyure sweetener. While still hot, I “frosted” mine with peanut butter, so delicious! Moist, chocolaty, and satisfying. Brava, Jennifer!
Traci says
This mug cake may be the one thing that lets me stick to this diet. It’s delicious and a definite keeper!
Debby says
Cant wait to try this recipe and where did you find the cute mugs?
jenniferbanz says
I bought that one when we lived in Germany. It’s Polish pottery.
Yvonne says
I have made this recipe a few times but tonight I added a few things. I did the chocolate cake with a splash of pure almond extract, a few sugar free chocolate chips and then after it was done cooking I poured 1.5 Tbs of full fat coconut milk like you would with a tres leches cake. It’s was AMAZING and the best mug cake I have ever had.
Anna says
Thank you so much for this recipe!! That was amazing! I’ve been trying different recipes and sweeteners trying to find a desert for when I have a craving and this is it! made the recipe exactly with coconut flour. For anyone who doesn’t like the taste of stevia/erythritol, I used a monkfruit sweetener and it was perfect. The lakanato monkfruit brand does have mostly erythritol in it but for me it’s been the closest replacement for sugar and doesn’t leave any weird alcohol/super sweet aftertaste. Just thought I’d mention incase anyone’s been struggling like I have been this past month adapting to low carb ?
Tomya says
I do not like eggs or things that taste eggy so I only added an egg yolk then a tablespoon of heavy cream in lieu of one entire egg. This made the best mug cake I’ve ever had, including full sugar/full flour/full carbs mug cake!
Melissa says
This was very good, but I realized afterwards that 2TBS of Swerve is TWENTY FOUR carbs. I damn near died. I can’t believe I ate that. ? There are 4 carbs in a TSP and 3 TSP is a TBS. On top of the coconut flour, this is just way off- and I made the vanilla flavor. It would,have been worse had I did the chocolate. Where did you get your calories/carbs from? Almost all of them came from the swerve and the red mill organic coconut flour. An egg only has 1 carb, and there’s nothing in the vanilla (at least mine) or baking powder.
Daniel says
The carbs are from erythritol which is not used by the body as fuel. It is absorbed into the blood stream and filtered out by your kidneys leaving in your urine. It has little to no effect on your blood sugar levels and can be pretty much ignored when figuring your carb intake when use in recipes.
Sommer says
The ‘net’ carb count in Swerve is zero.
“The ingredients in Swerve do not affect blood sugar, so the carbohydrates it contains are considered non-impact.” To figure net carbs (which is commonly done for the keto and low carb diets) you subtract the fiber and sugar alcohols such as the Erythritol, that Swerve is made from. This is how you arrive at zero net carbs for Swerve.
Melissa says
Thanks, but I don’t follow net carbs. I’ll try it again with monkfruit.
Yvonne says
It’s 0 net carbs. You minus the Erythritol from the total carbs. I was the same way until I looked it up.
Kathy says
The carbs in swerve don’t count because they don’t get absorbed in the body.
Dana says
Oh my! Delicious!
Bonnie says
THE best mug cake recipe of all time. Simple ingredients. Hits the spot!
