Equipment

  • 1 Medium Mixing Bowl
  • 1 Small mixing bowl
  • 1 8x8 inch metal baking pan
  • 1 Rubber Spatula
  • 1 whisk or fork
  • 1 sheet of parchment paper
  • Cookie Spray
  • Measuring cups and spoons

Ingredients
  

  • 2 cups All-purpose flour
  • ½ tsp Salt
  • 2 tsp Baking powder
  • 12 tbsp Unsalted butter 1½ sticks
  • 1½ cups Brown sugar
  • 1 Egg
  • ⅓ cup Sourdough Discard
  • 1 tbsp Pure Vanilla Extract
  • 1 cup Semi-sweet chocolate chips

Instructions
 

  • Preheat oven to 350℉
  • Spray an 8x8 inch baking pan with cooking spray. Line the bottom of the pan with parchment so that the long ends are sticking up from the edge of the pan (see photo).
  • Whisk together the flour, salt and baking powder in a small mixing bowl. Set aside.
  • In a medium sized, microwave-safe mixing bowl, melt the butter in the microwave for 30 seconds. If it is not completely melted, continue to microwave at 10 second intervals, stirring between intervals, until just melted.
  • Whisk in the brown sugar until combined. Add the vanilla, sourdough discard, and the egg. Continue to mix until well-combined. 
  • Slowly, stir in the dry ingredients until just combined and no dry flour clumps remain.
  • Stir in the chocolate chips until just combined. 
  • Spread the batter into the prepared baking pan, smoothing the top with a rubber spatula. 
  • Bake in preheated oven for 30-35 minutes. When done, the surface will be shiny and the edges should be firm and slightly golden. Give the pan a quick gentle shake. The blondies should not move much when they are done.
  • Allow to cool in pan to allow the blondies to set, around 30 minutes.
  • Use the long ends of the parchment paper to carefully remove the uncut blondies. Transfer to a cutting board and use a large, sharp knife to cut the blondies into 9 even squares.
