Peanut butter and chocolate go together better than peanut butter and jelly, if you ask me. You see, I'm not a huge peanut butter fan. I like peanut butter just fine if it's in cookie form or with chocolate. However, on toast or on sandwiches, I'd rather go hungry. It's a quirk I've had since childhood. With that said, these peanut butter swirl brownies were a great way for me to get my peanut butter fix! Also, the instant coffee sounded like an odd addition but it really enhanced the flavor of the chocolate.
