Sourdough Discard Blondies with Chocolate Chips

I really love blondies.

They’re like the lovechild of brownies and chocolate chip cookies. Not to be confused with brookies, which are also a crazy hybrid of brownies and cookies.

Blondies have all the chewy, gooey texture of brownies but the light vanilla flavor of chocolate chip cookies. Better still, these particular sourdough discard blondies also have a delightfully tangy, butterscotch flavor that make them stand out from other blondies.

Need I go on?

Oh, you know I couldn’t help myself.

Just look at them. They are so indulgent and naughty. And yet I can’t help but reach for another one because they are just that good. Even my daughter came in and grabbed a couple for herself.

They’re a great way to use up sourdough starter discard, but they’re also just a fantastic dessert all around. I love making them for guests, and for whenever I feel like snacking on something tasty.
