I've rejoined the keto lifestyle after 10 or so years, and used to follow a keto mug cake recipe way back then. I can't believe how GOOD this recipe is by comparison! This tastes like actual chocolate cake with absolutely no taste of egg whatsoever - and I followed the recipe to a tee. This has everything in regards to fluffiness, texture and flavour a chocolate cake should have . Your page is now saved as a one-click on my phone!

Made this tonight for my husband. I used coconut flour but it seemed too runny so I upped the amount to 2 Tbsp. It tastes pretty good but it is a little eggy. I'm curious, why is it 3 Tbsp almond flour when coconut is only 1 Tbsp? Seems a big difference.

I made the peanut butter one. Personally the sodium from the baking soda was too strong for me so I'll cut it down to 1/4 tsp next time but the base was great. I loved the consistency and it satisfied my craving for something bready.

  I just made the peanut butter one and it was quite delicious. You mentioned using baking SODA and the recipe calls for baking POWDER. This definitely makes a difference, so I wanted to send you a little comment in case you used the wrong one!
  I’ve accidentally used baking soda and it absolutely tasted salty when it normally doesn’t.

First of all, I love your baking recipes…they are the best! I made the chocolate mug cake with a few extra chips and chopped walnuts sprinkled over the top when it came out of the microwave. Very good. I made mine with the almond flour.if you want a quick dessert and don’t want any leftovers ,then this is perfect. I may try the vanilla next and add some lemon zest a few blueberries and a lemon drizzle next. Thanks for your great recipes.

I used coconut flour and Choczero chips. I sprinkled in some chopped walnuts as per the mug brownie directions. It was delish - filling and a good portion. Helps my cravings for dessert a few times a week as I am acclimating to the low-carb/keto eating regimen. I feel good! This did not upset my stomach (and my stomach is sensitive). Yum!

Loved this! I have previously done a almond flour/olive oil mug cake, but I was in the mood for something lighter. I made the chocolate version with coconut flour. Topped it with some homemade vanilla whipped cream. Yum!! And I was impressed at how moist it was! Definitely going to keep this one in my favorites.

I followed the directions but I must have done something wrong. I thought it was really awful. Maybe it needed less almond flour.

Most mug cakes aren’t good, but this one absolutely was. I used coconut flour because sometimes I just don’t want the heaviness of almond flour. I used a flax egg per another commenter’s suggestion. Delicious and helped my chocolate fix immensely.

I tried this one as airfryer mini muffins, and I haven't been able to stop eating them. SO MOIST SO AMAZING
I made the first batch with egg and after that with flax-eggs, and some more water. The second option is currently my favourite.
Thanks so much, I've been trying to get a lower carb breakfast pastry after the fathead pain au chocolat.

  You could try a flax egg. 1 tablespoon of flaxseed mill mixed with 2.5 tablespoons of water. let it sit for 5 minutes to thicken.

Do you think this recipe would work with just the egg white, which would make it less eggy tasting?

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.
