Soft and chewy Reese’s Pieces peanut butter blondies!

Reese's Pieces Peanut Butter Blondies | Persnickety Plates

I took a (very official) Facebook poll to see which you prefer – brownie or blondie. I think brownie came out slightly ahead but those of you that picked blondies should give these a shot.

Even if you’re usually a brownie lover, like me, try these.

They’re soft and chewy (there’s a lot of brown sugar in them) and are perfect with a glass of milk. (Plus, I threw some chocolate chips in the batter for good measure.)
