Ingredients
  

For the Blondie Batter

  • 1 cup sourdough starter discard contributes tang and moisture
  • 1/2 cup unsalted butter, melted adds richness and moisture
  • 1 cup brown sugar provides sweetness and depth
  • 1/2 cup granulated sugar adds sweetness
  • 2 large eggs binds ingredients and adds moisture
  • 1 teaspoon vanilla extract enhances flavor
  • 2 cups all-purpose flour gives structure
  • 1 teaspoon baking powder leavens the batter
  • 1/2 teaspoon salt balances sweetness
  • 1 cup chocolate chips (optional) adds richness and sweetness

Instructions
 

Preparation

  • Preheat your oven to 350°F.
  • In a mixing bowl, combine the melted unsalted butter with both sugars: brown and granulated. Whisk until well blended.
  • Add the eggs and vanilla extract, whisk until fully incorporated and smooth.
  • Incorporate the sourdough starter discard until evenly distributed.
  • In a separate bowl, combine the all-purpose flour, baking powder, and salt.
  • Gradually add the dry mixture to the wet ingredients, stirring gently until just combined.
  • If using, gently fold in the chocolate chips.
  • Prepare your baking pan by greasing it or lining it with parchment paper.
  • Pour the batter into the pan and spread it evenly. Tap the pan gently on the counter.

Baking

  • Place the baking pan in the preheated oven. Bake until the edges are golden and a toothpick comes out with a few moist crumbs, about 25 minutes.

Cooling

  • Remove the pan from the oven and allow to cool for 10-15 minutes, then transfer to a wire rack to cool completely.

Notes

These blondies can be served warm or chilled and are great for packing in lunch boxes or picnics. Store leftovers in an airtight container.
