Sourdough Chocolate Chip Cookie Bars

This recipe explains how to make soft and chewy sourdough chocolate chip cookie bars using sourdough discard in a quick, simple one-bowl method. The process involves preheating the oven and lining a pan, mixing cooled melted butter with sugar and sourdough discard, gently stirring in flour and salt, and folding in chocolate chips. The dough is pressed into the pan, baked until lightly golden with a soft center, then fully cooled before cutting into squares. The bars are easy, reliable, require no chilling, and the sourdough discard adds moisture and flavor while keeping the classic cookie taste.

Ingredients Equipment Method Notes

Ingredients
  

  • Sourdough discard or unfed starter
  • All-purpose flour
  • Butter
  • Sugar
  • Chocolate chips or chunks
  • Salt

Equipment

  • Mixing bowl
  • Spoon or spatula
  • Measuring cups and spoons
  • Baking pan
  • Parchment paper
  • Oven

Method
 

  1. Heat the oven to 350°F. Line a baking pan with parchment paper so the bars lift out easily.
  2. Melt the butter and let it cool slightly. The butter should be warm, not hot.
  3. Stir the sugar into the butter until it looks smooth and thick.
  4. Mix in the sourdough discard until the batter looks even and glossy.
  5. Add the flour and salt. Stir just until no dry flour remains. The dough should be thick.
  6. Fold in the chocolate chips so they spread through the dough.
  7. Press the dough into the lined pan. Smooth the top so it is level.
  8. Bake until the top is light golden and the center looks set but soft.
  9. Let the bars cool in the pan. Cut into squares once fully cooled.

Notes

Do not overmix once the flour is added or the bars can turn tough. Do not bake too long, or the center will dry out. Let the bars cool before cutting, or they may fall apart.
