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 have to add my vote! I have tried several keto mug cake recipes and they were ALL dry! This one is not. It smelled a little eggy when it was cooking but does not taste eggy. I made the chocolate with the almond flour and I will be making this again….and again….it is the absolute best! Not dry and a few Lily’s chocolate chips made it decadent.

    Oh my freaking god, this recipe is AMAZING. Discovered it last week as me, my wife, and my dad recently went keto. I was craving something sweet, so we made 1 mug to share. It was so good that I printed out the recipe (which I haven’t done for years) and stuck it on the fridge. 6/5, really a home run and so easy!

    We made it with coconut flour and it turned out excellent. We have made it 3 times since then. I put a dollop of peanut butter in the last time, and it was great!

    Tip for anyone reading: be careful to thoroughly combine the ingredients…on time 3 of making the cake, there was a little pocket of scrambled egg which was 100% my fault for not mixing properly.

    OMG I was sitting here dying for something sweet and “cakey” dreading yet another icky dry eggy so called bread or cake. I made this with almond flour (cannot stand coconut flour!) and threw a few sugar free white chocolate chips on top and I am in absolute HEAVEN!! Came out very moist and absolutely DELICIOUS!!! THANK YOU!!!

    Made the chocolate version for my diabetic husband’s birthday. Very delicious and moist! Would there be a way to make a lemon version?

      Maybe leave out chocolate as in the vanilla directions and add a few drops of lemon extract? Might also add just a little vanilla. This is such an easy recipe it might be worth a try.

    I tweaked the recipe to make a pumpkin spice version for fall. I replaced the cocoa powder with pumpkin pie spice and added three small dollops of cream cheese sweetened with the Swerve sugar, microwaved it for 1:30 minutes, and topped it with cinnamon and Swerve sugar. So good and a great way to get pumpkin spice in a keto way.

    Best vanilla mug cake I’ve made thus far! Can I add a Tablespoon of coconut flour and subtract a tablespoon of swerve? I had a little bit of an aftertaste that was not terrible but if I could lessen it, it would be perfection!

    You’re extra special to me because you were my first!! Lol! My first keto mug cake that is!! It was good and I felt like I was cheating. I posted a pic to my family via text message. I followed your instructions to make it and had great results. I was so proud of the finished product!! Thanks!!

      Isn’t 2 tablespoons of swerve erythritol (granulated) 24g net carbs?

      Reply
      • jenniferbanz says

        erythritol is zero net carbs

      • Melissa says

        October 24, 2019 at 8:02 am

        The bag of granulated erythritol i have says 4g Carbs per teaspoon. This would make it 24g carbs for 2 tablespoons (3 tspns =1 tblspn).

        Maybe the powder erythritol is different?

      • jenniferbanz says

        October 24, 2019 at 9:07 am

        erythritol is a sugar alcohol and the carbs are subtracted

    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 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.
