Do you think this recipe would work with just the egg white, which would make it less eggy tasting?
Yes, that will work
Dave H. says
WOW!!!!! I can't believe how good this tastes! I tried the chocolate version with Besti Monk Fruit & Allulose blend. I would never have guessed it was low carb. I will definitely be making this again when I'm craving something chocolate.

What do you use to figure out the nutrition facts?
A nutrition program
Omg....made the vanilla version with some lily's chocolate chips....definitely hit the spot!!
Carl J Greenfield says
I was craving something light and sweet for dessert and found this recipe. My daughter and I made the chocolate and peanut butter cakes using almond flour and an erythritol/monk fruit sweetener.
They were wonderfully delicious and really hit the spot. I will definitely make this again. I'm looking forward to trying some of the other recipes on this website.
I use only one tablespoon sweetener and 3 tablespoons blueberries for a breakfast treat. I found that I like to put it in my Dash bundt cake maker and cook for 8 minutes. It comes out perfectly!
I have made this the last three nights and am thrilled with the results. I made vanilla for my BF and chocolate for myself. He puts strawberries and heavy whipping cream on top of the vanilla and it is like a strawberry shortcake. I am chocolate everything. I have poked a few pieces of a dark chocolate bar in it, have tried it plain and w peanut butter in the chocolate which I also love. Probably won’t be baking a cake anytime in the future. This is easier and super tasty! Thanks!

what can we use as a replacement for butter?
Any oil will work

Made the chocolate version tonight and loved the texture and the taste. Used SOLA sweetener; there was no aftertaste. I like my desserts less sweet than general, so reduced the amount of sweetener. Added a dash of cinnamon and some orange zest as well as 1/2 of heavy cream in the mix( for some reason, the mix looked too dry), and it turned out amazing. Thank you!
The chocolate version was a delicious afternoon snack with a cup of tea. I microwaved it for 35 seconds, which was perfect -- not too dry, not too moist. And I used Costco's Kirkland brand almond flour. Thank you!
Made the peanut butter, I so needed that, thank you!
Barbara Showell says
Thank you, I NEEDED that!
I've made the chocolate a couple times and they're always soooo good... total game changer!
I made the vanilla with a dash of lemon infused olive oil for a a lemon version It was delicious!
R Fazzie says
I just made and ate this! Yummy! Excellent for a mid-afternoon hold me over until dinner! I made the almond flour version using half tbsp natural peanut butter and half tbsp unswt cocoa powder, I don't have choc chips. The only sweetener I had on hand is stevia, I used 4 of the tiny spoonfuls that comes in the bottle. Topped it off with 6 raspberries when it was done. Will definitely be making some version of this on a regular basis!
Robin Lisa Jessie says
Loving this! Chocolate recipe was spot on - fast easy and delish with just a dollop of whipped cream. Cant wait to try vanilla version and top with one of my keto fruit jams and peanut butter versions. Thank you!
after several tries, for my microwave oven, I cook it for 35 seconds. the bottom is not fully cooked and that's how I prefer it. Thank you for this review, it is sublime. I am from Quebec Canada
Made a chocolate one of these with the coconut flour. It overflowed my mug a little but not to much, and with a little heavy cream it was really tasty! I didn't have any chocolate chips but I didn't miss them. Thanks again!
Thank you for this delicious recipe.
I was craving scones with jam and cream today. I saw the idea to make a strawberry loaf, but wanted to trial it in a mug cake version.
So I used this vanilla mug cake recipe, & mixed in about a chopped frozen strawberry (I also added a touch more coconut flour to ensure it wasn't too wet).
In another bowl I put another chopped frozen strawberry, sprinkled lightly with sweetener, & lightly thawed in the microwave.
I finally added the cooked mug cake into the bowl with the strawberries, & added a thick dollop of cream on top. Extremely delicious and just what I wanted.
Thank you again!
I tripled the batch using coconut flour, baked it in a mini dash bundt pan. Made 4 cakes baked each for 8 minutes. Sprinkled with erythritol icing sugar. very good thought it would be a little dry because of the coconut flour but was quite moist.
I’m in shock of how good this was! It tasted better than chocolate cake. I did what some other comments had mentioned to do half coconut flour (.5T) and half almond (1.5T) then with pb and cocoa. It was delicious! I added a bit of heavy cream on top and it was heaven.
Best mug cake i ever tried. 😁
Hi ! I'm from Quebec, Canada. I made the chocolate version. It is the best I ever had so far. Thank you.
Thank you! So delicious - probably the best keto "mug cake" I have tried so far. Confession: I used both cocoa powder and peanut butter, no other adjustments, and it worked just fine. 🙂
This is so delicious and easy! Thank you so much!
I just made this for the second night in a row. Last night I made the chocolate version but I used cashew flour because I was out of almond. I broke up some sugar free chocolate on top. PIt was really good. Tonight I used the almond flour, cacao , and I broke up a coffee keto cup and microwaved it in. Then put some sugar free chocolate on top. oh my Gosh it was amazing!!
I just made the chocolate cake with almond butter. It was amazing and definitely satisfied my sweet tooth.😋
I love peanut butter! I made this up at about 5000 ft elevation…guess I needed to cook it a little bit longer! But, I still ate it! 😋
Can't thank you enough 😍 I made the peanut butter one. IT IS SOOO YUM!!!
Made the vanilla version with half the called for coconut flour (1/2 Tbl) and half the called for almond flour (1 1/2 Tbl) to get a balance of the two options. It came out fluffy and delicious!!! Perfect texture, and it pulled slightly away from the mug so no spray or anything was necessary.
I used my good old coffee cup to make this. Sprayed it with some coconut oil spray. It did not stick. Mixed everything in the cup for less mess. I also made a Vanilla and almond flavored version of this recipe. My favorite was the chocolate and peanut butter flavored though. Thank you so much for sharing you wonderfully creative cooking creations. I was getting bored with the same old recipes and this one was so simple! Keto ON girl!
PMS cravings had me ready to cheat, but Google lead me here. Cured the cravings and hit the spot. Pretty tasty too. Thanks for helping me stay faithful!
Robert G says
Hi Jennifer, the cakes look moist & delicious. What size ramekin are you using?
Thank you for sharing ❤️
Just made the chocolate mug cake. OMG….it’s delicious! A short time ago I found out I am diabetic and needless to say sweets are a no no. This cake really took care of my sweet tooth!!!
This mug cake recipe is very versatile. I made this a raspberry version using raspberry extract and Lily's raspberry-vanilla baking chips then a few smashed raspberries. It was delicious!
Has anyone tried these in a Dash Mini Bundt Cake Maker?
Chara Bale says
Add alittle peanut butter to the chocolate version with sugar substitute powered sugar. Uts delicious
chuck sanders says
I think it's one of the best recipes I've tried.........great texture and flavor. I got a little doughnut maker and I think this would work great for that too. You've gained a dedicated follower........thanks so much.
Mary Schreiner says
Yep, these do the trick! I liked the vanilla when made to the recipe, but the next time I made it I added a dash of nutmeg. I liked it with the nutmeg. Thinking about cinnamon.
this was so yummy. I had it with pouring cream and berries.It was heaven
Oups…. Couldn’t decide between chocolate and pb ! So I put both 😂
Thanks for this easy recipe!
So easy, versatile and delicious. We made the chocolate mug cake this time. My Granddaughter and I can't wait to try the vanilla one. Thanks for sharing
This is sooooo amazing! One of the BEST Keto recipes I’ve come across. This mug cake tastes like any other cake but only 3 net carbs! Super simple and quick, too. I treat myself to this cake a few nights a week with some freshly whipped cream and 1/4 cup of berries. I also pack the ingredients with me when I have dinner with friends so I can have dessert with them, too. Thanks for this awesome recipe and helping me stay Keto!
OMG! God bless your heart
This is Delicious, made the chocolate one, can't wait to try the others
Wow. I just tried the vanilla version, and it is delicious! My son, who is a stickler for traditional desserts, liked it too. This will be my go to recipe when I crave something sweet! Thank you.
