Peanut Butter Blueberry (PBB) Blondies

Moving is a bittersweet event. It's one of those moments that you approach both with a bit of a heavy heart as well as with a stomach full of butterflies. I've only been out in the Bay Area for about two years and some change, but this city has definitely become home to me (and Moses and #asausagenamedvienna). And now we're trading in our San Francisco city apartment for a spot in Los Angeles with a tiny yard and a lone fruit bearing apple tree (woot!!). I'm anxious, thrilled and ready to get down there and settle in at our new space in a new city but I'm going to miss this familiar and beautiful city by the Bay (and I am also dreading packing--I was supposed to start on Monday and didn't).

This may be a little cheesy, but I've decided that I need a moving theme song. And Steve Perry's song "Lights" will be said theme song. Why? Because who doesn't love Journey (everyone better love Journey) but also because I heard Perry wrote most of it in LA but finished it off in SF. Except I'll be singing Perry's original version, "When the lights go down in the city and the sun shines on LA." Seems like the perfect anthem to me. May it power me through the packing (and unpacking) stage of moving.


Please allow me to delay for another moment or two and share that I've been conjuring up blueberry recipes in my head instead of putting things in the boxes that haven't found their way into our apartment yet. I was set on doing a version of a blueberry flaugnarde (a claufoutis with a different type of fruit than cherries) but then I thought better of it and realized that I want to share what I bake with friends versus eat it all solo, because I'm also avoiding packing on lbs too.


Remember when I mentioned that my mother and father are both fabulous in the kitchen? Well they are, and while I was on the phone with my mom the other day, she mentioned she made Cook's Illustrated's Blondies and that my dad LOVED them, which was shocking because my dad loves brownies but isn't big on their lighter counterpart. After hearing that, I was sold and said, "Done, I'm making peanut butter and blueberry blondies." To which my mom responded, "Hmmm." But why wouldn't I put fresh blueberries together with peanut butter?! Who wouldn't love PB&J Blondies? Think of these as the better version of that. And be warned, these PBBs are like crack. So much for avoiding the lbs...I just ate three!

P.S. Let the countdown begin: two weeks!!
