These Chocolate Chip Sourdough Cookie Bars are a sweet treat with a delightful twist! Soft and chewy, they combine rich chocolate chips with a hint of tanginess from sourdough.
Honestly, who doesn’t love cookie bars? They’re a fun way to enjoy cookies without all the rolling and shaping. I like to serve them warm with a glass of milk—it’s heaven in every bite!
Key Ingredients & Substitutions
Unsalted Butter: This adds richness to the bars. If you’re in a pinch, you can use salted butter, but just skip the added salt in the recipe to keep the taste balanced.
Sourdough Starter: Use active, unfed starter for the best texture. If you don’t have starter, try replacing it with 1/2 cup of plain yogurt or buttermilk for a similar tangy flavor.
Chocolate Chips: Semi-sweet is classic, but feel free to mix in milk chocolate or dark chocolate chips. You can also use chunks for a fun texture or even dairy-free chips if needed.
All-purpose Flour: Regular flour works well here, but you can substitute with whole wheat flour for a slightly healthier option. Just keep in mind that the texture may change a bit.
How Can I Make Sure My Cookie Bars Bake Evenly?
Getting even baking is crucial for the perfect cookie bars. Here are steps to help:
- **Preheat the Oven:** Always preheat to 350°F. A hot oven helps the bars rise properly.
- **Parchment Paper:** Line the baking pan with parchment paper. This not only makes cleanup easier but helps with even baking.
- **Spread Evenly:** When transferring the dough to the pan, spread it out as evenly as possible. Press down lightly to help it compact.
- **Check for Doneness:** Bake until the edges are golden and a toothpick comes out with moist crumbs, not wet batter. This ensures they’re cooked but still gooey.
How to Make Chocolate Chip Sourdough Cookie Bars
Ingredients You’ll Need:
For the Cookie Bars:
- 1 cup (2 sticks) unsalted butter, melted
- 1 cup packed brown sugar
- 1/2 cup granulated sugar
- 1/2 cup sourdough starter (active, unfed)
- 2 large eggs
- 2 teaspoons vanilla extract
- 2 1/2 cups all-purpose flour
- 1 teaspoon baking soda
- 1/2 teaspoon salt
- 2 cups semi-sweet chocolate chips
- Flaky sea salt, for topping
How Much Time Will You Need?
This delicious recipe takes about 15 minutes to prepare and 25-30 minutes to bake. After baking, allow the bars to cool completely before slicing. So, in total, you’ll need about an hour, but most of that time is just waiting for the cookies to bake and cool!
Step-by-Step Instructions:
1. Prepare Your Pan:
First, preheat your oven to 350°F (175°C). Take a 9×13 inch baking pan and line it with parchment paper. Leave some paper hanging over the sides—this makes it super easy to lift the bars out later!
2. Mix the Sugars and Butter:
In a large mixing bowl, pour in the melted butter, brown sugar, and granulated sugar. Use a spoon or spatula to stir them together until the mixture is smooth and creamy.
3. Add Wet Ingredients:
Next, add the sourdough starter, eggs, and vanilla extract to your bowl. Mix everything well until it is fully combined. This is what gives your cookie bars a rich and tasty flavor!
4. Combine Dry Ingredients:
In a separate bowl, whisk together the all-purpose flour, baking soda, and salt. This helps to evenly distribute the baking soda for a nice rise in the bars.
5. Combine Wet and Dry Ingredients:
Gradually add the dry ingredient mixture to your wet ingredients. Mix just until everything is combined. Be careful not to overmix—you want it just right!
6. Fold in Chocolate Chips:
Now it’s time for the delicious part—fold in the chocolate chips! Use a spatula to mix them evenly through the dough.
7. Spread in the Pan:
Transfer the dough to your prepared baking pan. Spread it out evenly, and press it down lightly to compact it. This helps them bake uniformly.
8. Add Flaky Sea Salt:
Before baking, sprinkle some flaky sea salt on top of the dough. This adds a lovely contrast to the sweetness of the chocolate.
9. Bake:
Pop the pan in the preheated oven and bake for 25-30 minutes. Keep an eye on them! You’ll know they’re ready when the edges turn golden brown and a toothpick inserted in the center comes out with a few moist crumbs.
10. Cool and Slice:
Once baked, remove the pan from the oven. Let it cool completely in the pan on a wire rack. Once cool, use the parchment overhang to lift out the bars, then slice them into squares.
11. Enjoy!
Now it’s time to serve and enjoy these tender, gooey chocolate chip sourdough cookie bars! Perfect for sharing, or saving for yourself (no judgment here!).
Can I Use a Different Type of Sugar?
Yes, you can substitute the granulated sugar with coconut sugar or even brown sugar for a deeper flavor, but it may affect the texture slightly. Just keep the total sugar amount the same!
What If I Don’t Have Sourdough Starter?
If you don’t have sourdough starter, you can replace it with 1/2 cup of plain yogurt or buttermilk. This will add some tanginess to the bars, mimicking the sourdough flavor.
How Should I Store Leftovers?
Store any leftover cookie bars in an airtight container at room temperature for up to 3-4 days. You can also freeze them for up to 3 months; just make sure to wrap them tightly in plastic wrap and then in aluminum foil.
Can I Add Nuts or Other Mix-Ins?
Absolutely! Feel free to add chopped nuts, like walnuts or pecans, or even dried fruit for added texture and flavor. Just keep the total amount of mix-ins the same, about 2 cups in total.
