Step-by-Step Instructions
Preheat the Oven
Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking pan or line it with parchment paper.
Mix Wet Ingredients
In a large bowl, whisk together the melted butter, brown sugar, and granulated sugar until smooth. Add the eggs and vanilla extract, mixing until fully incorporated. Stir in the sourdough starter.
Combine Dry Ingredients
In a separate bowl, whisk together the flour, baking powder, and salt. Gradually fold the dry ingredients into the wet mixture, stirring until just combined. Avoid overmixing to keep the blondies tender.
Add Mix-ins and Bake
Stir in chocolate chips or nuts if desired. Pour the batter into the prepared pan, spreading it evenly. Bake for 25–30 minutes, or until a toothpick inserted into the center comes out with a few moist crumbs.
Cool and Serve
Let the blondies cool in the pan for at least 10 minutes. Slice into squares and serve.

FAQs
Can I Use Discard Sourdough Starter?
Yes, discard starter works perfectly in this recipe. The flavor will be slightly milder but still delicious.
Can I Make These Blondies Gluten-Free?
You can substitute all-purpose flour with a 1:1 gluten-free baking mix. Keep in mind the texture might differ slightly.
What Other Mix-ins Can I Use?

How Do I Know When the Blondies Are Done?
