How to Make Sourdough Blondies

Step 1. Begin by preheating your oven to a suitable temperature for baking. While that warms up, prepare your baking pan by lightly greasing it or lining it with parchment paper. This ensures your blondies can be easily removed once baked.

Step 2. In a mixing bowl, combine the melted and cooled unsalted butter with brown sugar. Use a whisk or rubber spatula to mix until the mixture is smooth and the sugar begins to dissolve, creating a glossy appearance.

Step 3. Next, crack the egg into the bowl with the butter-sugar mixture. Use your whisk to incorporate it fully, ensuring there are no visible traces of egg and that the mixture appears homogenous.

Step 4. Add in the sourdough discard and vanilla extract. Stir to combine until everything is well integrated and smooth, noting that the mixture may have a slightly thick consistency due to the sourdough.

Step 5. In a separate bowl, whisk together the all-purpose flour, baking powder, and salt. This step helps to evenly distribute the leavening agents and salt throughout the flour.

Step 6. Gradually add the dry mixture to the wet ingredients, folding them in gently. Stop mixing as soon as no dry flour is visible, as over-mixing can lead to a denser blondie.

Step 7. Once the batter is combined, fold in the toffee bits and semi-sweet chocolate chips. This not only adds delightful pockets of sweetness and chocolate but also creates a lovely texture throughout the blondies.

Step 8. Transfer the blondie batter into your prepared baking pan, spreading it evenly. Smooth the top with a spatula to ensure even baking.

Step 9. Place the pan in the oven and bake until the edges are slightly golden and the center is set. The blondies should appear firm, yet a bit soft in the middle, indicating they’ll have a nice chewy texture once cooled.

Step 10. When done, remove the blondies from the oven and let them cool in the pan before transferring to a wire rack. Allowing them to cool fully will help achieve the best texture for cutting.

Serving Suggestions

These Sourdough Blondies are wonderful for a variety of occasions. Enjoy them as a delightful breakfast paired with your morning coffee for a satisfying start to the day. They also make an ideal snack throughout the day or a sweet addition to family meals. If you have leftovers, they store well in an airtight container and can even be a sweet surprise for lunchboxes or picnics later in the week.

Pro Tips for Best Results

  • Make sure your butter is cooled after melting; this prevents the egg from scrambling when mixed together.
  • Avoid over-mixing the batter after adding the flour to maintain a lighter texture.
  • Allow the blondies to cool completely before cutting to achieve neat, even pieces.
  • Feel free to adjust the ratio of toffee bits and chocolate chips based on your preference.
  • Consider underbaking slightly for softer, chewier blondies if that’s the texture you enjoy.

Common Mistakes to Avoid

  • Overmixing the Batter: This can lead to tough blondies due to gluten development, making them dense instead of chewy. Mix just until combined.
  • Not Cooling the Butter: Adding hot butter can scramble the egg, resulting in an uneven texture. Allow it to cool before combining with the other ingredients.
  • Using Incorrect Measurements: Baking is precise, so be sure to weigh your ingredients for accuracy. Using too much flour can change the outcome completely.
  • Skipping the Parchment Paper: This can make it hard to remove the blondies from the pan, resulting in a messy presentation. Lining the pan helps keep everything intact.
  • Not Waiting for Cooling: Cutting into the blondies before they cool completely can result in crumbly pieces. Patience allows for a better texture.
  • Guessing Baking Time: Ovens can vary. Keep an eye on the blondies towards the end of baking to ensure they don’t overbake.

Variations & Substitutions

  • For added flavor, consider folding in chopped nuts for extra crunch and richness.
  • Experiment with different types of chocolate, such as milk chocolate or dark chocolate, depending on your taste preference.
  • If you prefer less sweetness, reduce the amount of toffee bits and chocolate chips.
  • For a cleaner flavor, you could use almond extract instead of vanilla, adjusting to taste.

Storage & Reheating

Store your Sourdough Blondies at room temperature in an airtight container for up to three days. If you want to keep them longer, refrigerate for up to a week. To freeze, wrap the blondies tightly in plastic wrap and then in foil, ensuring they’re well-sealed to prevent freezer burn. For reheating, pop them in a preheated oven for a few minutes to restore their soft texture, or microwave for a few seconds until warm.
