Chocolate Chip Sourdough Blondies

As a mom, I’m always on the lookout for quick, easy desserts that feel special without requiring hours in the kitchen.

Whether I’m making a sweet treat for my family on a cozy weeknight or whipping something up to share at moms’ book club, I want a recipe that’s both simple and guaranteed to please.

That’s exactly why I love making these Chocolate Chip Sourdough Blondies. They’re chewy, rich, perfectly sweet, and they make great use of sourdough discard—a win for both taste and reducing kitchen waste!

Can these Chocolate Sourdough Blondies be made for “On the Go” Moms?

Yes! Life with kids means I don’t have the luxury of standing over complicated recipes.

I need something I can mix up in just a few minutes, pop into the oven, and serve without fuss.

These sourdough blondies tick all the boxes—they’re mixed in one bowl, bake in under 25 minutes, and can be eaten warm or stored for later.

They’re also the kind of dessert that makes kids’ eyes light up while still being fancy enough to impress at a get-together with friends.

What Makes Good Chocolate Chip Sourdough Blondies?

A good blondie is all about texture and balance. You want that chewy, dense bite that sits somewhere between a cookie and a brownie, with just the right amount of sweetness.

The brown sugar and butter give these blondies a caramel-like richness, while the sourdough discard adds a subtle tang that balances out the sweetness.

Chocolate chips bring in gooey pockets of melted chocolate, creating the ultimate indulgence without being overly complicated.

What is Sourdough and Why Use It?

Sourdough is a natural ferment made by combining flour and water and allowing wild yeast and bacteria to thrive.

It’s often used for baking bread, but sourdough discard (the portion you remove during feeding) can be used in all sorts of recipes.

Using discard in baked goods not only helps cut down on waste, but it also adds a wonderful depth of flavor.

In blondies, the sourdough brings a slight tang and complexity that makes them stand out from traditional versions. Plus, sourdough can be a little easier to digest, which is an added bonus.

Can I make these Chocolate Chip Sourdough Blondies for a large party?

If you’re feeding more than a few people—or you’re preparing something for a party—it’s super easy to scale up this recipe.

Simply double the ingredients and bake the blondies in a 9×13-inch pan instead of an 8×8. They’ll come out just as chewy and delicious, with plenty to share.

Common Mistakes to Avoid

Even with a simple recipe like this, there are a few pitfalls to watch out for:

Overmixing the batter – This can make your blondies tough instead of chewy. Mix just until everything is combined.

Overbaking – Blondies should come out slightly soft in the middle. They’ll continue to set as they cool.

Too much sourdough discard – Stick with the amount in the recipe. Adding more can throw off the texture and flavor.

Not lining the pan – Parchment paper makes it so much easier to lift the blondies out cleanly.

Tips for Making the Best Chocolate Chip Sourdough Blondies

Here are a few tried-and-true tips to ensure your Chocolate Chip Sourdough Blondies turn out perfect every time:

Use room temperature ingredients – This helps everything blend together smoothly.

Reserve some chocolate chips – Sprinkle them on top before baking so the blondies look extra inviting.

Don’t skip the sea salt – It enhances the flavors and balances the sweetness.

Let them cool before cutting – As tempting as it is, cooling helps them firm up so you get neat squares.

These Chocolate Chip Sourdough Blondies are a Treat Everyone Will Love

These Chocolate Chip Sourdough Blondies are proof that you don’t need an elaborate recipe to create something crowd-pleasing.

They’re chewy, buttery, chocolatey, and packed with just enough tang to make them unique. Sure, they’re not the “healthiest” dessert around, they use both butter and sugar, but at least when you make them at home, you get to control the quality of your ingredients.

I like to use organic brown sugar and good-quality chocolate chips, which make them taste even better.

And since they’re so easy, you’ll find yourself coming back to this recipe again and again.

Step-by-Step Recipe: Chocolate Chip Sourdough Blondies

Ingredients

• 1 cup brown sugar – adds rich caramel-like sweetness and chewiness.
• 8 tablespoons (1 stick) melted butter – brings buttery flavor and keeps the blondies moist.
• 2 teaspoons vanilla extract – enhances the overall flavor with warm, sweet notes.
• 1 large egg – helps bind the ingredients and gives structure to the blondies.
• 1 cup all-purpose flour – provides the base and structure for the bars.
• 1/4 cup sourdough discard – adds a subtle tang and reduces kitchen waste.
• 1/2 teaspoon baking powder – gives a slight lift for the perfect chewy texture.
• 1/4 teaspoon sea salt – balances the sweetness and highlights the flavors.
• 3/4 cup chocolate chips – melts into gooey pockets of chocolate in every bite.

Instructions

1. Preheat your oven to 350°F (175°C). Line an 8×8-inch baking pan with parchment paper.
2. In a large mixing bowl, whisk together the brown sugar and melted butter until smooth.
3. Add the vanilla and egg, whisking until combined.
4. Stir in the sourdough discard until fully incorporated.
5. Add the flour, baking powder, and sea salt. Mix gently until just combined—do not overmix.
6. Fold in the chocolate chips, reserving a handful to sprinkle on top.
7. Pour the batter into the prepared pan and smooth the top. Sprinkle with the reserved chocolate chips.
8. Bake for 20–25 minutes, or until the edges are golden brown and a toothpick inserted in the center comes out with a few moist crumbs.
9. Allow the blondies to cool completely in the pan before lifting them out with the parchment and cutting into squares.

Melting the butter when making blondies is key to achieving that dense, chewy texture that blondies are known for.

Unlike creamed butter, melted butter blends easily with the sugar, helping create a fudgy consistency and rich, buttery flavor without incorporating too much air.

This method also makes the recipe quicker and simpler since there’s no need for a mixer or softened butter.

Melted butter is commonly used in other baked goods where a chewy or moist texture is desired, such as brownies, cookie bars, and certain chocolate chip cookie recipes. It’s also great for quick breads like banana bread or zucchini bread, where moisture and flavor are more important than lift.

Using melted butter is an easy way to elevate simple desserts while keeping them soft, rich, and incredibly satisfying.

These Chocolate Chip Sourdough Blondies are the kind of dessert that makes you look like a hero in the kitchen without all the stress. They’re easy, versatile, and perfect for family nights, playdates, or sharing with friends.
