Flourless Chocolate Peanut Butter Cup Cake

You remember Sarah, the one who brought us the lemon white chocolate biscotti and the crunchiest caramel popcorn in the world. Well, now it's our turn to give something to Sarah. 

You see, Sarah, like all sane people, has a true passion for all things chocolate peanut butter. So for her birthday, I made her this.

Of course when I brought this cake over for the party, I decided to be annoying and tell her I had to take a left over piece home so I could photograph it for you guys.

It only took me about five hours to choose the perfect piece to take home. It had the most perfectly smooth edges, the fluffiest frosting, the most perfectly nestled peanut butter cup, and of course, the most perfect ganache.

So when I got home that night, I set it on the counter, ready to photograph when the sun came out in the morning.

Imagine my horror and rage when I woke to find that my most perfect slice of chocolate peanut butter cake had been destroyed. Someone had nibbled off the whole tip of the perfect ganache. After a thorough investigation, the culprit was discovered. I won't name names, but I'll give you a hint, it's the sister that is now living in eternal disgrace for her crime.

Seriously though. I was really pretty levelheaded and all is now forgiven. Okay, so I might have thrown a few Reese's cups at her face or told that she could never eat cake in this town again, I don't remember.

Just don't ask her for her side of the story.

P.S. This cake is naturally gluten free! Check it out on my gluten free blog here.
