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 wish I could give it more than five stars. This is such a great treat! I added a pinch of salt and some unsweetened coconut chips. So light and fluffy and pure chocolate goodness. Thank you so much for posting this awesome recipe!

    OMG! I’ve made mug cakes before, only to throw them out because they were disgusting. This was delicious. My husband loved it and kept saying it can’t be Keto. We shared it, I added freshly whipped cream, no chocolate chips, and cooked it for 50 secs. His birthdays is in a couple weeks, and he said he’d have that en lieu of a full, sugar laden, chocolate cake.
    THANK YOU!

      I was having a MAJOR chocolate craving and this took care of it. Not only easy, quick but also delicious! Hubby and I shared it as well and I had to prove the carb content because he said it tasted too good to be low carb/Keto! Thanks for posting this and saving me. The struggle is real!

      It came out a little bit salty. I noticed that every time I try one of the cake recipes. Moist though

        Amazing. I drizzled ChocZero chocolate sauce on top. This will be my new go-to dessert when I don’t feel like baking.

      Hi Jennifer, the chocolate mug cake is fab!!! You are such a good low carb cook. I have recently added 1 tablespoon of sour creme to the mug cake and it makes it super moist. Give it a try!!! Hope u like it!!!

      I am a professed chocoholic. Being new to keto I often crave it. This mug cake is a winner! It was absolutely delicious and worth every star! I used almond flour and so nourished erythritol monk fruit blend. The cake was soft and fluffy. Definitely going in my dessert rotation.

    My husband and I are OBSESSED with this recipe. Anyone know a way to make a full cake? I’d love to be able to make it for the other Keto girls at work.
