Ingredients

Scale

Wet Ingredients

  • 8 tablespoons butter (melted)
  • 1/4 cup sourdough discard
  • 1 egg (room temperature)
  • 2 teaspoons vanilla extract

Dry Ingredients

  • 1 cup all-purpose flour
  • 1 cup light brown sugar
  • 1/2 teaspoon baking powder
  • 1/2 teaspoon salt

Add-ins

  • 3/4 cup chocolate chips (divided into 1/2 cup and 1/4 cup)

Instructions

  1. Preheat and Prepare Pan: Preheat your oven to 350°F (176°C). Grease an 8 x 8 inch metal baking pan or line it with parchment paper. Avoid using a glass pan as it can affect baking results.
  2. Mix Wet Ingredients: Melt the butter in a microwave-safe bowl or on the stovetop. In a large mixing bowl, whisk together the melted butter, sourdough discard, and the room-temperature egg until smooth and combined.
  3. Add Sugar and Vanilla: Stir in the light brown sugar and vanilla extract into the wet mixture, mixing until the sugar fully dissolves for a smooth batter.
  4. Combine Dry Ingredients: In a separate bowl, whisk together the all-purpose flour, baking powder, and salt until evenly distributed.
  5. Incorporate Dry Ingredients and Chocolate Chips: Gradually add the dry ingredient mixture along with 1/2 cup of chocolate chips to the wet ingredients. Stir until just combined and then spread the batter evenly into the prepared baking dish. Sprinkle the remaining 1/4 cup chocolate chips on top.
  6. Bake: Bake the blondies in the preheated oven for 20-25 minutes. The center should be slightly undercooked and jiggly to ensure a chewy, fudgy texture after cooling. The blondies will puff up during baking and then sink back down as they cool.
  7. Cool and Cut: Allow the blondies to cool completely in the pan to set. For cleaner slices, chill them in the freezer for 15-20 minutes before cutting into 9 large or 12 small squares.

Notes

  • Use a metal baking pan for best results; glass pans can cause uneven baking.
  • Do not overbake to maintain a moist and chewy center.
  • Cooling completely before cutting ensures clean slices and helps prevent crumbling.
  • Freezing briefly before slicing makes cutting easier and neater.
  • Room temperature egg helps create a smoother batter.
