Another amazing recipe! This one came just in time for a birthday party I was hosting. You’re a life saver š
Hot fudge sauce on my couch, my sweatpants, and my camera.
And Bjork just informed me that I have a little leftover on my face. #worthit
This, well, there are no words for this. This is chocolate peanut butter perfection. I thought I had already found chocolate peanut butter perfection, which I pretty much did. But here comes chocolate peanut butter perfection round two, and it’s taking on a whole new level of ooey-gooey deliciousness.

And guess what? Just guess. You will never guess what I’m about to tell you, but I want you to guess anyways. I hate it when people do that.
Here it be: this chocolate euphoria is essentially guilt-free! Essentially! Like, eat it and get skinny.
I’m totally kidding and serious at the same time right now. Just look at the stats below.
After I made this, I was feeling real good and real healthy.
But then something predictable happened. My brain went —> chocolate —> must.have.peanut.butter. And then I whipped up a little batch of not-guilt-free creamy dreamy peanut butter sauce. I added a teeny tiny spoonful of said sauce to my cake. And ever since that moment I’ve been drowning in peanut butter sauce.
Oh my wonderfulness. This stuff is heavenly. Which is why I did us all a favor by keeping the peanut butter sauce nutrition facts to myself, k? Yep.

PS. I used my regular slow cooker for this recipe which is a Crock-Pot that I’ve had for the last five years. SO MUCH FOOD has come out of that thing over the life of this blog which is pretty impressive for a $28 kitchen appliance.

As I mentioned, the nutrition facts are just for the ooey gooey fudge cake. You don’t even want to know about the sauce.
Just go eat some healthy cake covered in peanut butter sauce and all will be right with the world.

Is there a way to make this in a pan or skillet as opposed to slow cooker? I want to serve it for a dinner party?
We haven’t tested this out in a pan or a skillet yet, but this recipe here might work better. Enjoy, Danielle!
Hi,
I have just found your blog and cooked the skinny vegetarian lasagna for the family for dinner and everyone loved it. At only 200 calories a serve it was guilt free aswell.
Now for dessert I made the chocolate fudge cake with peanut butter sauce and we were blown away with the taste and contentment we felt after just one of the 8 servings each.
So much so I just couldn’t believe it was only 200 calories also so I added all the ingredients into my fitness pal and they came out as just over 300 calories per serve.
I’m wondering how you kept it down to 200 calories??
I’m aiming for 1200-1800 per day to loose weight so that extra 100 calories does at times make a difference.

Hi, Michelle! Is it possible you added nutrition facts for the peanut butter sauce as well as the cake? The nutrition facts we have published are for the cake only – no sauce.
Hi Lindsay
First things first, Love your sense of humour. Secondly, of course the simplicity of your recipes. I have just joined your email list. I am an amateur Blogger and your blog and tips inspire me so much.
Just like the previous comment I’d like to know what I can use instead of a Crockpot. Maybe the oven, for how long would I need to bake the mixture.
Greetings from Cape Town
Great question, Pumla. Earlier on in the comments, Lindsay suggested to another reader to bake this at 350 degrees for 15 minutes, and then check it regularly (every 5-10 minutes) thereafter until it is done. If you make this in the oven, we’d love to hear your feedback and what worked for you! š
Hi,
Love the pictures and description. Really want to make it but I don’t own a crockpot. So couldn’t bake the same cake in an oven? Would I need to make some changes in the recipe if I cook it in the oven?
This looks soooo good. Are crockpots same as ramekins?
Try it,
I haven’t tried this but I LOVE, LOVE, LOVE peanut butter! I am avoiding looking at the actual recipe part for fear that I will make this delectable, by the sounds of it, sauce and then end up drinking it by the batch!
PS. Even if I never ever try this recipe, I am a happier person. You are a funny lady!! I laughed out loud a couple times. Thanks for the happy! š
You don’t include the baking temperature…….350?
It’s actually made in the crockpot, so I didn’t set a temperature. But if you decide to bake it in the oven I’d go for 350, checking on it every 15 minutes or so.
Hey you did mention that if using the oven to bake at 350 and check every 15 mins…does the toothpick need to come out clean or slightly wet??
Another amazing recipe! This one came just in time for a birthday party I was hosting. You’re a life saver š
Yay! This cake would definitely make for a happy birthday. š
