Low Carb Flourless Chocolate Peanut Butter Cake. The last low carb mug cake recipe you will ever need.

One of the things I never really liked about low carb mug cakes was their wet, almost spongy texture. While they curbed the chocolate craving, they never quite felt like cake. WELL, here is a recipe that will change that. This flourless chocolate peanut butter cake is moist and dense and best of all it is ready in just under 2 minutes.

I made this just a few minutes ago and although I really enjoyed the texture and the Chocolate flavor, I found it to be salty. Could it be due to the butter? Or the peanut butter? Did anyone else experience this?
Carolyn Brack-Jackson says
I think if you use unsalted butter, logically, it would taste less salty! I would try it!
Marie says
this looks wonderful! i can't wait to try it, especially after all these rave reviews. just one question, is the cream necessary? or am i able to use almond milk in place? thank you!!
Peace Love and Low Carb says
I'm sure almond milk or coconut milk would work just fine.

Made this tonight when the high stress of studying created a therapeutic chocolate emergency. The peanut butter topping was the clincher for choosing this recipe over the scads of others on my Pinterest board.
Oh...my...goodness! It was the therapeutic rescue needed, at just the right time!
I doubled the recipe and split it between two ramekins, microwaving one at a time. Turned out perfect. In the future I will probably add a few chocolate chips to the top while the mug cake is still hot. I use Lily's Stevia chocolate chips, so just a few will make a spreadable frosting consistency once they soften.
This recipe got added to a private board on my Pinterest page: Hubby Faves. It's like the Hall of Fame. Lol

Patrice says

Thanks so much! So happy you enjoyed it.

Could you use a normal egg instead of a pasteurised one?
Peace Love and Low Carb says
It isn't pasteurized, it is pastured. That simply means that the chicken was allowed to roam free in a pasture, eating the things it would normally eat, plants, insects etc. I just refuse to eat a factory farmed egg. But you can use any type of egg you want in this recipe.

This is my first time commenting on ANY recipe I've tried and this is the absolute best there is. I topped it with just a small scoop of crunchy almond butter and the extra texture of the nuts made this so amazing.
The flourless part makes it so good. There is no grainy texture. It tastes, feels, smells like cake!
The only thing is I was afraid of my cake drying out so I set it to only 1 min and it worked out for me. I prefer my cakes runny so I'd hate to eat a dry cake!
Thanks so much for this recipe! I've tried 4 different low carb mug cakes and I'm definitely sticking with this whenever I get the craving.
Peace Love and Low Carb says
What a rave review! Thanks so much!
Julie says
Can't wait to try this. I second the praise of no; almond flour, coconut flour! Could you please tell me
the wattage of your microwave. Mine is 900 which takes longer than 1 minute to cook these cakes.
Thanks!.
