These Maple Pecan Sourdough Blondies are an easy fall dessert made with sourdough discard, brown butter, and warm maple flavor, baked into soft, chewy bars packed with pecans.

I'm having a bit of a moment with sourdough discard blondies.
It started with a strawberry white chocolate version for spring, then a s’mores take for summer, and now I’m sharing in a maple pecan version for fall.
These maple pecan sourdough blondies are made with maple syrup, pecans, white chocolate chips, and brown butter for a soft, chewy cookie bar packed with warm fall flavors.
After making several batches, I gave some to my dad (who loves all things pecan) and he couldn't stop raving about them.
Whether you need an easy fall dessert for Thanksgiving or just something sweet and cozy, these blondies are one you’ll want to make on repeat.

Ingredients & Substitutions
Here are some notes on key ingredients. For a full list of ingredients, check out the recipe card below.
- Sourdough Discard- Adds a subtle tangy flavor and is a great way to use up leftover discard. Use room temperature discard for easier mixing.
- Pecans- Add crunch and nutty flavor. Toast if desired. Walnuts, pistachios, or almonds can also be used.
- White Chocolate- Adds sweetness and pairs well with the maple flavor. You can substitute chocolate chips or leave them out entirely.
- Maple Syrup- Adds sweetness and a subtle maple flavor. For the best flavor, use pure maple syrup instead of pancake syrup.
- Brown Butter- Gives the blondies a rich, nutty flavor and chewy texture. Let it cool slightly before mixing into the batter.
- Maple Extract- Enhances the maple flavor.
- Kosher Salt- Balances the sweetness and enhances flavor. I use Diamond Crystal Kosher Salt (2.8 grams per teaspoon). If using Morton’s or table salt, reduce to ¼ teaspoon.

Tips for Success
- Weigh your ingredients. A kitchen scale helps ensure accurate measurements and gives you the perfect texture every time.
- Use an aluminum pan. Aluminum pans bake more evenly and help prevent overbaked edges or an underbaked center.
- Bring ingredients to room temperature. Room temperature eggs and sourdough discard mix more smoothly into the batter.
- Expect a thick batter. The batter will be thick, so use a spatula to spread it evenly in the pan.
- Cool completely before slicing. Let the blondies cool fully before cutting so they set properly and slice cleanly.
