Ingredients for the Best Sourdough Blondies Ever

Preparing the Best Sourdough Blondies Ever
Creating the best sourdough blondies ever is an adventure that marries the tangy goodness of sourdough discard with the rich sweetness of classic blondie recipes. Let's dive into the steps you need to follow to achieve this irresistible treat!
Gather your equipment
Before you start baking, it’s essential to have your tools ready. You’ll need:
- Mixing bowls to combine your ingredients
- An 8x8 baking pan to keep those blondies nice and thick
Taking a moment to ensure you have everything at your fingertips will streamline your baking process and let you focus on what truly matters: making delicious blondies!
Preheat the oven and prepare your baking dish
Begin by preheating your oven to 350°F (175°C). This is vital for achieving that perfect golden-brown exterior. While the oven warms up, either grease your 8x8 baking dish or line it with parchment paper. Using parchment makes for easier browning and, of course, effortless cleanup—because we all love a hassle-free kitchen!
Whisk together the dry ingredients
In a medium bowl, whisk together the following dry ingredients:
- 245 grams all-purpose flour (about 1 ¾ cups)
- 2 grams baking powder (½ teaspoon)
- 3 grams fine sea salt (½ teaspoon)
Whisking these together ensures even distribution, which helps your blondies rise beautifully. Plus, it adds an extra moment to savor the anticipation of what's to come!
Mix the wet ingredients
In a large bowl, combine:
- 170 grams unsalted butter (melted)
- 210 grams light brown sugar (packed, about 1 cup)
- 100 grams sugar (½ cup)
- 100 grams sourdough discard (⅓ cup)
- 1 large egg (room temperature)
- 1 egg yolk (room temperature)
- 8 grams pure vanilla extract (about 2 teaspoons)
Whisk until everything is beautifully smooth, and don’t hold back! This is where the sourdough will start to transform into something dreamy.
Combine dry and wet ingredients
Now, it's time for a little teamwork. Gradually fold the dry ingredients into the wet mixture using a rubber spatula. When you see just a few streaks of flour, gently add in your chocolate chips (or any other mix-ins like pecans or walnuts) and fold until everything is perfectly blended.
Spread the batter and top with chocolate chips
Transfer that creamy, luscious batter into your prepared baking dish. Spread it evenly, then add a sprinkle of chocolate chips on top. Extra chocolate can never hurt, right? This will create a melty topping that complements the soft, chewy blondies.
Bake to perfection
Now, let’s get to the exciting part: baking! Place your blondies in the preheated oven and let them bake for 35-40 minutes. Keep an eye on them—the edges should look golden, while the center remains slightly soft. Overbaking can lead to dry blondies, and that’s just tragic!
Cool and slice the blondies
Once baked, allow your blondies to cool completely in the pan. Patience is a virtue here; it makes slicing easier and helps develop those delightful flavors. After they’re cool, cut them into 8 large or 16 smaller squares, and enjoy the best sourdough blondies you’ve ever made!
By following these steps, you’ll not only waste less sourdough discard but also treat yourself to a delicious, mouthwatering dessert that’s sure to impress. Happy baking!

Variations on the Best Sourdough Blondies Ever
Nutty Blondies with Pecans and Walnuts
For a delightful twist on the best sourdough blondies ever, try adding chopped pecans or walnuts. These nuts not only provide a pleasing crunch but also enhance the rich, buttery texture of the blondies. Toasting the nuts before mixing them in can elevate their flavor even further, giving your bars a warm, nutty aroma. Just fold them in during the last step before baking, and you’ll have a delicious treat that's perfect for sharing with friends.
Fun Flavor Twists with White Chocolate or Butterscotch Chips
Feeling adventurous? Swap out the classic chocolate chips for white chocolate or butterscotch chips to introduce new flavor profiles to your sourdough blondies. White chocolate lends a creamy sweetness, while butterscotch offers a delightful caramel taste that beautifully complements the sourdough base. You could even do a mix-and-match approach, using both to create a unique blondie experience. The possibilities are endless—don’t hesitate to get creative!
Baking Notes for the Best Sourdough Blondies Ever
Importance of Measuring Ingredients Accurately
Getting the right measurements for your ingredients is crucial to achieving the best sourdough blondies ever.

Tips for Browning Butter
Browning butter adds an irresistible nutty flavor that elevates your blondies to new heights. To achieve this, melt your butter in a pan over medium heat while stirring constantly.
