Sourdough Chocolate Chip Cookie Bars
There are so many ways to use your sourdough starter. Breads, pastas, cookies, cakes, muffins and so much more. Today I want to share a true favorite at our house. These sourdough chocolate chip cookie bars and ooey, gooey, flavorful treats. The taste is incredible while having just a hint of that sourdough flavor.

What you’ll love about this recipe:
I love making cookies, but sometimes making cookies into bars is the easiest and best way to get a consistent product. It also takes less time since you are only baking these once instead of baking multiple pans.

These sourdough chocolate chip cookie bars are so addicting. They have that chewy texture of a cookie but are also slightly cakey and oh so soft. They’re like a brownie cookie hybrid if I could describe them I guess.
I mean, look at all the gooey goodness. Now, if you want them less gooey, just bake them slightly longer. Thats the great thing about this recipe. You can bake it to your preferred doneness.

Nutrition
This is a great way to use up sourdough discard, if you have any. It is also a great way to add good gut benefits to your recipe. If you want to leave this batter in the fridge overnight to add more of the sourdough benefits you can. But who wants to wait that long? These sourdough cookie bars are so awesome you wont want to!
Tips & Tricks
- You can use parchment paper in the bottom of your pan for easier removal after baking.
- Combine your wet ingredients first, and then fold in your dry ingredients until just combined. Do not over mix. You want these to be tender and soft.
- Store these cookie bars in an airtight container for later enjoyment. Or eat them all in one sitting. Whatever calls to you that day haha.
- You can sprinkle extra chocolate chips or chocolate chunks on the top if you need more chocolate but I find the two cups is more than enough.
- You can use sourdough discard straight from the fridge. You can also use active starter. It really makes no difference for this recipe.
- Use milk chocolate chips or semi-sweet chocolate chips for this dessert.
- You do not need a stand mixer for this recipe. The dough is slightly looser than a normal cookie dough and is easily mixed together. I find it much easier to mix by hand.
