Do you know how much I love my microwave? I am team microwave! Keto Mug Cake is another one of my favorite recipes using that trusty machine!
My 90 second Low Carb Bread is another one of my microwave recipes. So good for sandwiches!
This keto mug cake is so easy to make with only 6 ingredients.
It’s also easy, rich and chocolatey, and ready in under 5 minutes!
For this keto mug bread, you can make it chocolate or vanilla. All you need to do is omit the cocoa powder from the recipe for a vanilla version that is just as delicious!
You’ll also see in the recipe card below that I provide instructions for almond flour or coconut flour.
I’ve really grown to love coconut flour lately because it is so much more affordable than almond flour. I know some people do not like the taste of coconut flour, so almond flour instructions are provided!

I made this a week ago with coconut flour, it was pretty good, but the coconut was “crunchy.” This time, tonight, I made it with PB flour. Everyone loved it! So good! The PB flour to almond flour ratio is 1:1, so just substitute the same amount of PB flour, as you would use almond flour.
What a great idea! Thanks for sharing!
What is PB flour? Would love to try it because I don’t love coconut flour. Thanks!!!
Peanut butter flour
It’s just dehydrated and ground peanuts. I used PB Fit in mine, which has a little added sugar, but is still less carbs than most natural PBs.
It was a sign! I had all the ingredients so I just made one! Oh wait, did I mention I like it so much I think Im going to make another!!
so glad you liked it!
WOW!!!
My hubby quite often does a low carb diet, but with a sweet tooth he struggles for dessert ideas. THIS IS PERFECT!!
Pinning and making REAL soon!
Low Carb is the best!
I made this last night … absolutely amazing !!! It has definitely made it into my favorite recipes book! Can you give us a nutritional count on this one though … I couldn’t find any values other than calories.
So glad you liked it, Susan. I have added the nutrition info to the post.
I made the keto cake yesterday! I loved it so much I made it again today! Thank you! I absolutely LOVE this recipe. ( I used coconut flour)
Yay! So glad you liked it!
I love your mug! Do you remember where you bought it?
It is Polish pottery that I bought in Germany. I have tried to find something similar with no luck!
OMGOSH!!! Just went on eBay and typed polish mug!!! A bunch to choose from!
PLEASE tell me you have a link for that gorgeous mug????!!!!! OH! And beautiful recipe!! Thank you! xoxo
Sorry, Marie! I wish I could find another one but it is Polish pottery I bought when we lived in Germany.
That’s ok!! Just went on eBay and typed Polish mug! There are quite a few that are similar!! Yay!! Ty!!
Can I use Splenda or Stevia instead for the sweetener? I have those on hand!
You definitely could but I’m not sure on the amount
I just made the vanilla version of this using coconut flour. Yowza it was extremely sweet. Is 2 tblsp of swerve a typo and supposed to be teaspoons instead? I’ve looked at the recipe over and over figuring my old eyes read it wrong. I will definitely make it again but I’m going to pare down the swerve for sure. 😊
My daughter just made the chocolate cake and we loved it. The texture and flavor is perfect. Thanks for sharing!
So glad you liked it!
I made the Vanilla mug cake & added a few choc chips- this turned out GREAT! It hit the spot for my sweet/cake craving & I only finished half of it- it was filling!
I just made the vanilla and it seemed very eggy tasting. I followed the recipe exactly. Does this sound normal or did anyone else notice this happened to them?:(
Keto desserts can have an eggy taste because they are heavy on the eggs. You could try using just egg whites next time.
I just made the chocolate mug cake with coconut flour, but it turned out very soggy and granular. Any ideas why?
Coconut flour has a granular texture. Almond flour would be a little smoother
I have never tried cake in a mug but I have to say this was delicious!! This really satisfied my cake craving 😊
I made this tonight, but rather than the chocolate chips I decided to put 2 tablespoon of spreadable cream cheese on top of the chocolate version. It was so good.
sounds amazing!
I make this nearly everyday, sometimes twice! Just be careful not to overcook it or it’ll be dry. I usually let it stay a little runny and then mix it all up.
Great idea!
I just made this vanilla mug cake with a few alterations because my husband needs to be dairy free. I used 1 tablespoon coconut oil instead of butter, one and a half tablespoon each of coconut flour and almond flour, 1/2 tsp vanilla. Very mild flavor and perfect texture. It was delicious with raspberries or strawberries (slightly sweetened) on them.
I just made it for my keto husband for father’s day weekend! Of course today was just the trial run and I’ll be making it again tomorrow for desert with father’s day dinner!
thank you so much!
I made the vanilla version just as written, and used it for a strawberry shortcake base. It was perfect; husband says to pin this recipe! Thanks for doing the experimenting and posting delicious recipes.
Thank you for the great review!
