this is by far the best recipe for keto cake I have ever used. I ended up halving the amount of sweetener and cooking it for a bit longer. ( in Germany maybe the power is different in the machine) The cake is moist, tasty and so fast to make. Straight out of the microwave I top it with a couple of pieces of 80% dark chocolate.
Jey Jey says
Needed a chocolate hit at the start of my monthly time and this filled the craving with sheer deliciousness. Low carb too as I did not need the chocolate chips.
Kylea says
It didn’t have much flavor I probably recommend 1/2 teaspoon of vanilla or a full teaspoon.
Shannon Bird says
Best mug cake I’ve ever had, keto and otherwise!
Imola says
Just made it, yummy! I made the one with cocoa powder, added some peanut butter on top while it was hot and sprinkled onsome keto granola. Accidentally added one tbl spoon coconut flour AND a tbl spoon almond four, came out like a chocolate cake base.
Sharmy says
Thank you so much for this lifesaving recipe. I made the peanut butter version, so moist and so tasty. Tastes even better than regular mug cake. Thanks a lot Jennifer
Shelley W. says
Excellent!
I tried the vanilla with peanutbutter!
I used coconut flour and golden monk fruit sweetner.
Yum!
Thank you Jennifer ~
Jackie says
Jen,could I use brown sugar instead and pecans? Could you add a variation of that?
jenniferbanz says
Yes, just replace the sweetener with brown sugar sweetener and add some pecans
Lorraine says
This is a game changer! Turned out perfect first time and soooo yummy, I really won’t miss sugar filled cake when I have this!!! Made the chocolate version, will do peanut butter next time. I used stevia and good quality cocoa, it wasn’t bitter at all, as good as any restaurant 😋
Victoria says
Honestly it tasted bitter. I followed all steps. Maybe I will try coconut flour instead of almond. Definitely eggy taste.
Den says
Agreed. Like an artificially sweetened egg mudball. One minute in the Microwave, it rose over the edge then fell into a gummy mass. Yuck.
Kristin says
Delicious, today your Chocolate cake was my Sunday morning breakfast, I used almond flour, and stevia powder, I always use 1/3 of the baking powder because the one I have here in Belgium tastes too strong. I ate it while it was still warm, a very very happy start of the day, thank you so much, Jennifer
Dawn says
Very good!! I made chocolate peanut butter and man was my mouth happy! Thanks for the recipe!
Kerrianne says
I made this I used monk fruit sweetener. It turned out great!! Low carb and no sugar !! Still so goo and helped take away my sweat craving
Cynthia says
Delicious!! And so easy. Thank you
Charly says
This also makes 4 cupcakes! Perfect for the only one on keto in the house. Love it!
V. A. P. says
What a great substitute for diabetics with a sweet tooth!
Alex G says
This is the best mug cake I’ve made. Love it
Leila McCartney says
I made this today and it was perfect. So quick and easy
Joanne says
Hi I can’t wait to try these they look so delicious…can you please tell me what size ramekins you use? I just purchased 8 ounce ones. Thank you!
jenniferbanz says
yes, 8 ounce works
Deb says
The bomb! Quick fix for a sweet tooth.
Michelle says
Best mug cake recipe I’ve found – by far. Both times I’ve made it, I’ve used coconut flour, Keto cocoa powder, almond butter, and Truvia. I love that it gives me my dessert fix, is filling, and keeps me in ketosis.
When I first made it, I put it in a ramekin and it overflowed BIG TIME (still tasted good). Maybe ramekins come in different sizes but I don’t see how this recipe can fit into one (even if it were just the vanilla one with coconut flour). Definitely use a mug.
I found that 45 seconds works well (with my microwave, at least). However, I feel like some parts were overcooked and some parts were undercooked, so I plan to play with the power and cook time settings to figure out what works best.
Kathryn Cheeswright says
I just made a cross over of chocolate and peanut butter and it was super delish!
Mohamed Abulkhair Mohamed says
Really yummy the chocolate version with coconut flour but I added tablespoon Club soda. Thanks
Kimmy says
I’m not sure why people are saying it tastes like scrambled eggs. Honestly, I think it’s something they are doing or their microwave. I have made this several times and have always been successful. You may want to let the melted butter cool just a bit before adding the egg, that may be the issue? I’ve tried the chocolate and vanilla and I have experienced with different variations too. Thanks for a simple, easy and fast dessert idea for one! It definitely satisfies my sweet tooth 🙂
Dagmar says
SOOO DELICIOUS!!!!
I made the chocolate mug cake with coconut flour and it was absolutely delicious! We could share 1 serving and add a scoop of Carb Smart vanilla ice cream on the side with sugarfree chocolate syrup and whipped cream.
Ellen Adkins says
I made the chocolate mug cake
With sugar free chocolate chips
On it…So Easy and I love it and the recipe
Thanks Jennifer
Natalie Malbeuf says
Literally so good!! It hits the spot when im craving something fun. Thanks
Juno says
Came out not cooked and had to do a whole extra minute…do not recommend this recipe
Sm says
I made the vanilla version exactly as the recipe called for and it was not good. It was very eggy tasting and to me and my husband, it was like eating a sweetened, scrambled egg cake. I even tried the recipe twice and neither one of us could get past the eggy taste. I don’t know if that’s what it’s supposed to taste like, but the egg was overwhelming. I did not use extra large eggs either.
Wendy says
Best mug cake recipe I’ve tried!
+So far, I’ve made a plain vanilla, chocolate with Lily’s semi-sweet baking chips and RediWhip topping, and another vanilla with 3/4 tsp of cinnamon stirred in and topped with chopped pecans… and RediWhip, of course.
This is an awesome recipe… thank you!
JGT says
I made the chocolate cake. I added some sugar free whipped topping and a couple of chocolate chip over it. So good!
Holly DeGroot says
Oh my goodness I thought I’d have to give up mug cakes when I start eating like this, but this is delicious! I made the vanilla one with monkfruit sweetener, coconut oil-based butter, and topped with a few Lily’s chocolate chips, and it is sooooooo good! Can’t wait to try the other two! Note: I don’t count net carbs, just doing a SF, DF, GF Candida diet.
Thanks so much for these, Jennifer!!!
Carol Barrett says
OMG ! This is so yummy!
I made mine with coconut flour what a treat
The best one I have ever tasted thanks so much
Marti says
Wow this is terrific! I made the vanilla with coconut flour. Added TBS of ground nuts
Whipped heavy cream added Dash of cinnamon Hit the spot! This is My first week on keto lost 11 lbs. really needed a goody
Going to try mug bread next. Thanks for this receipt !
Monica Kovacs-Barnes says
I made the chocolate version with coconut flour and Swerve confectioner’s sugar replacement. Would you mind breaking down how you got 7 grams total carbs for yours, because when I put all the ingredients in my carb counter (I use Carb Manager), it added up to 34.5 gms total carbs. That does include the chocolate chips (Lily’s) for 8 gms carbs, but still much higher than what your recipe states. Thanks!
jenniferbanz says
Carb manager must be including erythritol in the carb count
Naomi says
So so so so good! I have tried a few different mug cakes and this is my favorite one by far! I made the chocolate one. What I want a cake to taste like!
Heidi Uecker says
I made the chocolate version using coconut flour following the recipe exactly. It was moist and delicious. I will be making this a lit!
Mina says
Hi, I just made the vanilla one with almond flour and it was really yummy and moist. It’s super hot here in France today but I still fancied some cake. It was really nice to be able to make one without making the house any hotter because of the oven. Thank you for sharing this great recipe!
Kelsey says
I just made the vanilla version but used brown sugar Swerve… it almost tastes like a pancake! This was amazing!
Kirsty G says
Maybe a silly question, but still fairly new to keto, for the chocolate cake, is that 7 g of carbs already net carbs? Or is it total carbs?
Thanks 😊
jenniferbanz says
That’s total carbs. Subtract the fiber to get net carbs
SaraP says
I made this tonight. I added a scoop of vanilla protein powder and a splash of half and half. It was really good but needed an extra 20 seconds in the microwave. I also added some frosting that was made out of whipped cream cheese and sweetener. Thanks for the great recipe!
Emmy says
Wow, I was so sceptical but this is great. I did vanilla but added a bit of cinnamon and it’s perfect!! Thank you!!
Nena Ortega says
The best chocolate cake-in-a-mug recipe I’ve had, yet! Not dry at all, and plenty chocolate flavor. Even my husband approved, and he is not a fan of anything not sugar sweetened. Thanks for the great recipe!
Leslie says
I have tried so many keto mug cakes trying to fill my immense want for a tasty cake. This is the only one that truly just tasted like cake. I poured a small amount of heavy whipping cream on top after melting some keto chocolate chips on my chocolate cake and it was amazing. Thank you. I will definitely be checking out more of your recipes.
Janice says
Oh my goodness……yes yes yes…just what I needed! So easy and so good …I used coconut flour and dark cocoa…topped with powdered swerve….and a few Lilly’s chips. It was perrrrrrrfect. I need a coconut cake mug cake next….. Thankyou!😁👏
Susan Butcher says
Excellent very filling
Susan Harover says
I haven’t made any of these yet, but can’t wait to try! Looking at the nutritional info, can you tell me how the chocolate can have 12 g of protein in it? I know eggs have 6 g of protein, but where does the other 6 g come from?
jenniferbanz says
Almonds in the almond flour
Lydia says
Soo yummy, that’s what I need with my night cup of tea. Thanks for sharing 👌
Maddie says
Wow, this is amazing. Just the thing for a late night craving. I made the chocolate coconut flour version without heavy cream, but you better believe I’m ordering that now for the next time I make this.
Victoria Murray says
Very good!!
Paula says
I’ve made the chocolate cake with almond once and then with coconut flour. Definitely preferred the coconut flour texture and it was so delicious!! Can you please let me know what the macros are when using coconut flour? Thank you!
G says
tasted good but all of my chocolate chips sunk to the bottom of the mug, not exactly sure what could have caused this. Either way a great recipe!!
Michele says
So easy , fabulous!
Cat says
I combined the peanut butter & cocoa (1/2 tbsp of each) & it was decadent and ohhh so yummy!! Thank you
Char says
I NEVER write reviews but this was awesome, really indulgent , totally hit the spot . Thanks for sharing 🧡
LaToya says
I made this and something didn’t come out right. The taste was terrible. I think I didn’t use enough stevia. It had an aftertaste. Any suggestions on what I possibly got wrong? I plan to try it again. I tried the vanilla one. I’ve only been on keto a week so I’m new to this.
jenniferbanz says
Yes, stevia can have a bitter aftertaste. You may want to try erythritol ❤️
Jum says
I was impressed…. it cane out delicious. I made just the vanilla. It hit my sweet tooth.
Patti says
Love the chocolate peanutbutter mug cake. Very light and totally delicious. Did not need any toppings. Thx
Stephen Hepburn says
Tried the chocolate version this afternoon. I used honey as a sweetener. Cooked for only 50 seconds in a 900w microwave and it turned out perfect. Lovely texture using the coconut flour. This will be my go to Sponge recipe from now on. Many thanks.
Thyanne says
Just made this. Absolutely delicious. Needed this for my craving.
Pam says
Im excited to try this. I just want to make sure Im understanding right. It’s 1 Tablespoon of coconut flour OR (not plus) 3 Tablespoon of almond flour. Is this correct?
jenniferbanz says
Correct!
Linda says
The cakes are so very good!!! Thank you for the recipe’s!! I wondering on the Analysis of the nutritional information do we subtract the fiber from the carbs to get the net amount of carbs or have you already done that?
Thank you so much !!!
Linda
Daphyne says
Yes, Linda. You subtract the fiber or sugar alcohols from carbs to get the net carbs.
Kelcey says
Finally, a keto dessert that isn’t bitter and doesn’t taste like pure eggs! Best recipe I have tried so far. All the other ones I had tried were extremely eggy and had no flavor. Thank you.
Lin Jawish says
I’ve missed cake, and this recipe really hit the mark. Thank you so much for that, I’ve been looking for an easy cake recipe and when I stumbled upon yours I thought to try it out. It did not disappoint.
Didi says
This was way better than non-keto mug cakes! We loved it.
This is her 3rd recipe I tried so far and all were awesome.
Thank you.
KJ says
I’ve tried several microwave cakes and never gotten any to work except this one! The texture is lovely.
Jessica says
Best mug cake ever.
Thank you!
Stephanie says
Thank you, the PB was amazing, will definitely make it again, sooo easy!
Angela says
Delicious! I used mine for strawberries and some cream.
Kari Vaisanen says
Nice recipes again – thank you. I just don’t like to use your “favorite brands from Amazon” while some of them are too expensive and/or not available in my country.
Kirsten says
Delicious !! Thank you.
KC90 says
I hate… ok detest keto mug breads but this was beautiful!
Sonia Quintanilla says
Thank you i’m going to try it 😋😋😋
Sharon Ells-Jakiel says
Made this last night. This could become a problem. The absolute best cake in a mug!
Nicole says
OhMyGosh! I just made the vanilla option and baked it in the oven. It is so delicious. Mine did take 15-16 minutes but I started watching it closely at 10 minutes. This may have also been because I baked it in a round glass container and not a mug. I also used coconut flour as I was out of almond flour. This is going in my recipe book for sure.
bwenda says
PERIODT my mom loved it thanks
