Skinny Peanut Butter Brownies

After the not-so-light recipe I posted earlier this week, I have something a little bit healthier for you today.   But I promise, these skinny brownies taste amazing!!  I was skeptical when I first saw this recipe  – I mean how can you make a brownie without oil or butter?  But I was intrigued so decided to try it out.  And wow, am I glad I did.  These brownies are amazing!!  They are so moist and fudgy – and the peanut butter swirl just puts them over the top!  As a bonus, they are so pretty!  I felt like a kid in art class making the marble swirl of PB on top of the batter.
