Best mug cake recipe I’ve ever made hands down! I’ve only tried the chocolate so far, but will definitely be trying the others soon. 🙂
Elizabeth J Malave says
Didn’t have Vanilla but made the chocolate cake without, simple and easy, delicious with the coconut flour and topped with keto cream cheese frosting, sooooo good. Thank you for another solid recipe!
Carmen says
Ok…LOVE my chocolate mug cake!! Will try pb next!!!
Stephanie says
I made the chocolate mug cake tonight using coconut flour. It was amazing! So amazing that I let my kids try it and I got up to put a load of laundry in the dryer. When I returned my mug cake had vanished. They’re response was they needed a full taste test! Needless to say, I’m glad it was easy to make another mug.
Jules says
Perfect ending…
Samantha says
So I made the chocolate one and it was great. I plugged in the recipe into my my fitness app the carbs amount to 20g. And that’s with only 1 tbsp of swerve. The numbers you listed for the carbs was 7 carbs? Is that supposed to be net carbs or regular carbs?
jenniferbanz says
Swerve has zero carbs and my fitness pal does not reflect that.
Samantha says
So I’m only 3 weeks into keto so I’m definitely not experienced, on the package of swerve it says 1 tsp has 4 carbs. I really enjoyed this cake is why I’m asking. When I plug in all the ingredients in to make a recipe on my fitness app the total came out with 20 grabs and I was shocked. I double checked the Ingredients and the swerve was what was high. So I think I’m missing somthing.
Krystal says
Sooo good!!!!
Shannon Delozier says
Tried this tonight and was amazing.
Janeece says
Delicious, so easy! Vanilla is our favorite. I use only 1 TBS Swerve, add cinnamon. We serve with a few spoonfuls of Keto brand ice cream – Sea Salt Caramel. Love this. Thank you Jennifer!
Cristy says
Best ever! I used Hershey’s special dark cocoa (100%) and made my own clarified butter topped it with 4 raw pecans and it was fantastic! Looked like a dark devil’s food cake and 2 T of erythritol was not too sweet for me! Now if I could only get my diabetic brother to try it!
Margaret says
I’ve made these and they are delicious, but I found that 2 tablespoons sweetener was way too much. I only use 1 tablespoon and they are plenty sweet enough without the extra carbs and aftertaste.
su says
best mug cake(s) recipe. hands down!!
Pat says
Made the chocolate one with milk chocolate Lilly’s chips. Very good will make again!!
Cindy Mac says
Enjoyed the taste. I did not use a lot of sweetener and the result was a muffin like cake in a mug. Also the taste was not super rich chocolate. If you’re looking for a super chocolatey cake use more cocoa. Yum!
Laura says
Made one chocolate and one peanut butter with chocolate chips. Had a little cold coffee so added one tablespoon to the chocolate! Yum!!! My husband wouldn’t share his peanut butter one haha. Total fan of these super easy treats??
erin stickle says
Excellent! I put 1/2 tsp espresso powder in the vanilla recipe, added some whipped cream and had “tiramisu”! Yum!
erin stickle says
It was very good! I added a half tsp espresso powder to the vanilla recipe with some whipped cream and had some “tiramisu”!
liz says
I also forgot the 5 stars!
liz says
OMG these are the best, I tried lots of different recipes last time I low carbed. None of them were as good as these. Well done and Thank you!
Ellie Y says
Amazing! Added a few macnut pieces. Outstanding,! Thanks for sharing!
Carmen says
Sorry…forgot the 5 stars!!!
Kirsten says
First off let me start by saying that my husband hates cake (would rather eat pie) — were new to keto and were both craving something sweet tonight .. so I made myself a chocolate cake and my husband the peanut butter cake. He devoured it and so did I! Both were AMAZING and DELICIOUS and we are excited to be able to indulge every now and then and not feel super guilty about it!
Val Wall says
Delicious! Thanks for posting!
Ann says
Just curious ……is it really 1 T of coconut flour OR 3 T of almond flour?
jenniferbanz says
yes
Dana says
Yes, coconut absorbs moisture so you need MUCH less!! Trust it!! 🙂
Kathy says
One of my hubby’s favorites of all time! So easy to make too. I top it with a square of 90% chocolate, peanut butter and a sprinkle of cacao nibs. He loves it!
Susan says
Excellent mug cake recipe! Thank you so much!
Keto Hypnotist says
Wonderful recipe! I added walnuts and wow these were good.
Miranda says
I have made a TON of different keto mug cakes – this one is by far the ABSOLUTE BEST!!! I made a double batch in a larger dish, planning on saving it, and my kids devoured it after their tiny test bites! Yum!!!
Ann says
Just made the vanilla variation for a sweet fix after lunch. It was perfect, many thanks!
Jennifer says
Just amazing! I put a naughty twist on this and made cuts in the sponge, then poured a tiny bit of Bailey’s Almande and put a few raspberries and a dash of single cream as I saved up my macros! Yum yum yum. Thank you Jennifer
Felicia says
Love the chocolate! Next up is PB!
Jenny says
Love this recipe. I’ve also added lemon and salted caramel flavouring to them. Haven’t had a bad one yet. So quick and easy for a sweet fix
Sunny Dawn says
just finished off the chocolate mug …. super great! and moist and tastey and sooo easy to make .. no fuss no mess .. thank you for a great recipe! i’ll be trying the 2 other flavors soon
Elisa says
This was delicious!! I’ll definitely be premixing packets of the dry ingredients for this. Thanks for the awesome recipe!
Melissa says
Have you tried a full cake version of the chocolate peanut butter? The mug is amazing, I want to make a larger cake, but a little lost on how to convert.
jenniferbanz says
I sure haven’t but that sounds amazing!
Jillerie says
I added cream cheese. 2 tbsp cream cheese, heat for 20 seconds in the microwave, mix in 1/2 tsp Truvia (sweetener). Once mug cake is fully blended, drop by spoonful into batter, then swirl one time. Microwave for 1 min, 20 seconds.
Soula says
Forgot to add 5 ? Oops ?
Soula says
Great recipe.
Tried it with maple syrup instead of sweetener
Worked a treat
I’m paleo so I’ve swapped all sweetners for coconut sugar and maple syrup.
I only needed 1tb as I don’t like sweet things anymore.
Don’t even eat chocolate chocolate anymore either.
Thank you for this awesome yummy recipe.
I accidently added 1tb of tahini in the chocolate mug cake recipe and tasted really good too haha

WoW! Love the chocolate mug cake and it was so easy to make. I added a tablespoon of Lily no sugar dark chocolate chips and I’m eating it now. Matter of fact, I’m going back to it…
Janelle A says
One of the best mug cake recipes I’ve had!
I’m usually keto but currently pregnant, but I still love baking with stevia.
I made the peanut butter version, and added in some banana
Super moist! Me ( and baby) are fans !
Maureen says
This is a great recipe. Made the Peanut Butter version. Delicious!
Brenda says
Good for a quick fix! Next time I’ll use monkfruit instead of Splenda and microwave for 55 seconds as mine was a bit dry, as you warned. Nice dessert, or breakfast!
Marcy says
I made the chocolate version. Best ever!!
Gina says
Wow – this is delicious. I used coconut flour; was out of baking powder, so subbed a tsp of “2 Good” Yogurt, and added both the chocolate and sugar-free crunchy peanut butter. Topped with a few of the sugar-free chocolate chips. Awesome yumminess – thanks for the recipe!!
Zubi says
Ohh my God!!
Thank you so much for great recipe ?? l am in heaven now ?
I just tried the chocolate mug cake and it was no different then a real cake. I added 5 raspberries before cooking in the microwave and and it was kore delicious with sourness of raspberries.
I can’t wait to try others ?
Lauren says
Used coconut flour and maple syrup and it turned out absolutely delicious!! I added frozen triple berries and heavy whipping cream on top to make it a match made in heaven?
Nina says
This is soooooo goood! So happy I found your recipe!!! For the chocolate cake version – is it 7g carbs minus the 4g fiber so it’s 3.5 net carbs total?
jenniferbanz says
yes
Brenda says
Jennifer I am so happy I found you. Your recipes are really good?
Lisa says
I made this and the batter looked VERY thick… I added a tablespoon of almond milk… it tasted okay but not sure why it seemed rather dense. I used it as a trifle cake, layered with HWC and fresh raspberries, so it was still quite tasty. Served in stemmed wine glasses for effect.
Any idea why it came out so dense? I made the vanilla version.
Tasha says
Ooh, this is so good. Thank you! I put a sugar free chocolate coconut candy in my mom’s and topped it with whipped cream and sugar free chocolate syrup.
Morgan says
I have tried SO many mug cakes and this is by far the best! I made the chocolate one using almond flour and it is rich and decadent while remaining moist. Thank you!!
