Main Ingredients

  • 1 cup unsalted butter, melted Adds moisture and richness
  • 1 cup brown sugar Provides sweetness and a deep flavor
  • 1/2 cup granulated sugar Balances sweetness and adds texture
  • 2 large eggs Binds ingredients and adds moisture
  • 1 teaspoon vanilla extract Enhances flavor
  • 1 cup all-purpose flour Provides structure
  • 1/2 teaspoon baking powder Adds lift and lightness
  • 1/2 teaspoon baking soda Helps with leavening
  • 1/2 teaspoon salt Enhances overall flavor
  • 1 cup sourdough starter discard Adds moisture and a slight tang
  • 1 cup chocolate chips Optional; adds sweetness and texture

Instructions
 

Preparation

  • Start by melting the unsalted butter in a saucepan over low heat, or in a microwave-safe bowl in the microwave. Melt it just until it’s fully liquid, then allow it to cool slightly.
  • In a mixing bowl, whisk together the melted butter, brown sugar, and granulated sugar until it forms a smooth mixture.
  • Add the eggs one at a time, whisking well after each addition, and then mix in the vanilla extract.
  • In another bowl, combine the all-purpose flour, baking powder, baking soda, and salt. Stir the dry ingredients together until well mixed.
  • Gradually add the dry mixture to the wet ingredients, stirring gently until just incorporated.
  • Fold in the sourdough starter discard until everything is combined.
  • If using, add the chocolate chips and fold them into the batter.
  • Pour the batter into a prepared baking pan, smoothing the top with a spatula.

Baking

  • Bake in a preheated oven until the edges are set and the center is slightly soft, about 20 to 25 minutes.
  • Let them cool slightly in the pan before transferring to a wire rack to cool completely.

Notes

Ensure the butter is not too hot when mixing to avoid cooking the eggs. Let the blondies cool completely before cutting for cleaner edges.
