Hot Fudge Cake with Peanut Butter Sauce

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.
