Peanut Butter Cookie Dough Brownies

I have a new dessert today to share with you today. It’s so good that you may race to the store just so you can make these for the kids today. (Or yourself. Go ahead, I won’t judge. Promise.)  And frankly, I’m not quite sure why it has taken me so long to put this combination together. It’s no secret that I love have an obsession for chocolate and peanut butter. Really it’s a combination that you can’t go wrong with. Ever. Let me introduce you to my new best friend: Peanut Butter Cookie Dough Brownies. You are going to love her. I mean, how can you not?

Chewy chocolate brownies layered with peanut butter cookie dough and topped with chocolate peanut butter ganache? Oh. My. Goodness. If you don’t agree with me as to heavenly these are, I’m not sure we can be friends. I like them THAT much.

My base layer is one of Smitten Kitchen’s brownie recipes. (Why mess with success, right?) But then I couldn’t leave well enough alone and added a layer of peanut butter cookie dough (no eggs, of course). And then to make sure things stay together nicely I frosted everything with a chocolate peanut butter ganache. It’s chocolate peanut butter nirvana.

Now as much as I find it hard to believe, I know that chocolate and peanut butter isn’t for everyone. So tell me – what have I been missing while I’ve been devouring these brownies? Leave a comment below, and let me know what else I need to try. I’d love to know your favorite flavor combination!
