Oh my goodness! Just made the vanilla one, reduced the sweetener to ½ a table spoon then put some lemon juice over the finished item. Blooming lovely!
Brenda says
I just made the chocolate mug cake with almond flour. It was perfect I followed your exact directions. This is now my top favorite mug cake. Thank you so much for sharing.
Ayesha shaikh says
This is an amazing recipe, I've made it 5 times by now for a healthy dessert quick fix. I have even made it without the butter & just 1 teaspoon peanut butter. Still EPIC.
Helen says
Fantastic! I even did it wrong. Added peanut butter and chips after 50 seconds. So moist and delicious. Thank you!
Angela says
I’m Angela! I just sent u an email! Just wanted to say I forgot to add baking powder and vanilla! Lol it was still delicious
Angela says
Omg I just made the chocolate mug cake! Delicious
Chelsi says
I tried the vanilla recipe, it came out very rubbery and the egg taste almost overpowered the sweetness. Felt like I was eating a vanilla scrambled egg.
fi says
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.
Jamie says
I've made your chocolate mug cake twice now and it's devine! Moist, fluffy and truly satisfying. I will try the vanilla next. Thank you for creating such an easy, wonderful, low carb recipe for us keto heads to enjoy.
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

Alex G says

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
