Less decadent than its chocolate-based counterpart, the blondie often suffers from an overly enthusiastic addition of sugar. Enter Elisabeth Prueitt, champion baker and co- founder of San Francisco’s Tartine bakery. In an updated version of her 2006 baking bible, Prueitt mixes a perfectly balanced blondie: not too sweet, yet full of complex flavor, thanks to finely ground Earl Grey tea leaves and a salted caramel swirl. Taking the blondie far beyond basic, Prueitt gets the classic dessert just right.
