What makes sourdough blondies stand out?
- Depth of Flavor: Sourdough adds a complex depth, enhancing the buttery, caramel-like sweetness of the blondie base.
- Chewy Texture: The sourdough helps achieve a perfectly chewy texture, making each bite satisfying and delicious.
- Buttery & sweet: The use of butter and the mix of brown and regular sugar makes these blondies uniquely delectable.
- Versatile: While this recipe uses the addition of chocolate chips, feel free to get creative. White chocolate chips or walnuts make excellent add-in as well.

Tips for Success
- Use a metal pan: Using a metal pan for baking sourdough bondies is recommended for even heat distribution. This ensures they are cooked evenly.
- Room Temperature Ingredients: Use room temperature ingredients to ensure even mixing and a smooth batter.
- Measure Accurately: Weigh your ingredients for precise measurements, especially the flour and sugar, to achieve the desired consistency.
- Sourdough discard: I recommend using discard no more than a week old as this may result in a sour result.
- Do Not Overmix: Mix the batter just until combined to avoid developing too much gluten, which can result in tough blondies.
- Cool Completely: Allow the blondies to cool completely in the pan before cutting to prevent them from falling apart.
