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 bought the liquid Stevia (SweetLeaf Sweet Drops SteviaClear). Could I use that, and if so how much?
Peace Love and Low Carb says
I don't typically cook with liquid Stevia. If you try it out and like it, be sure to report back 🙂
Dev says
Stevia has to bind with agave or coconut sweetener to work when heated. So depends on how much you want to experiment. Good luck.
Rebecca says
I would start with 5 drops taste for sweetness and then add one drop at a time till it's sweet enough for you.
Cindy W. says
Oh, my goodness! This was wonderful :-). I let myself get so hungry I was shaky, so I made this up really quickly and it was amazing! Thanks for a new sweet / chocolatey dessert/snack ...
Shannon says
Made this tonight because I had an unbelievable cake craving. The erythritol did not work for me at all,so I switched to xylitol and added one more tbsp and it was very good!! Now you need to figure out how to make a vanilla one with that same texture and you will be my hero for LIFE!!!!!..lol...

how about subbing cocoa for vanilla protein powder
Krista says
This was so amazing, I was really looking for something to get rid of my peanut butter cravings since eating half a jar of peanut butter with chocolate chips isn't exactly low carb. For anyone who hasn't tried this please do, you will not be disappointed! I even put a little whip cream on top with a few SF chocolate chips on top, so good!!
Petra Stephens says
I suppose it would matter what size the PB jar was.
Danielle says
This was awesome!!!!! I loved that it was super simple and yet was still very tasty. I thought I heard angels singing when I took my first bite.
amy h. says
amen sista! i think angels were singing, just now, for me too! i also drizzled some torani sugar-free vanilla syrup on top ((in addition to the melted peanut butter)). SWEET HEAVENLY BLISS!! holy yummers! :^)
Bettie says
I cannot eat peanuts but I am certainly going to make this with Almond Butter which tastes like peanut butter used to taste to me. And of course, CHOCOLATE makes everything taste good!
Angie says
I don't have a microwave- do you think this could be done in an oven?
Heidi says
I used a similar recipe and baked it in my toaster oven for about 15 minutes. Came out great! 🙂
Jennifer says
OMG - YES!! No coconut flour - no almond flour - no dry, grittiness. YUM!!
