If you love classic chocolate chip cookies but want something even easier to bake, these Sourdough Chocolate Chip Cookie Bars are the perfect treat. They have everything we love about cookies—soft texture, melted chocolate, and rich flavor—but in a simple bar form that’s easy to slice and share.
I first made Sourdough Chocolate Chip Cookie Bars when I had extra sourdough starter sitting in my kitchen. Like many home bakers, I hate wasting sourdough discard. Instead of throwing it away, I decided to experiment with a dessert recipe. The result was amazing. The sourdough added a subtle depth of flavor that made the cookie bars taste even better than regular cookies.
These bars are soft in the center, slightly crisp on the edges, and filled with gooey chocolate chips. They are perfect for beginners because you don’t need to scoop individual cookies. You simply spread the dough into a pan, bake it, and cut it into bars.
Another great thing about Sourdough Chocolate Chip Cookie Bars is that sourdough fermentation can make baked goods easier to digest for some people. Plus, using sourdough discard helps reduce food waste, which is always a good thing in the kitchen.
Whether you want a quick dessert, a lunchbox treat, or something sweet to enjoy with coffee, these cookie bars are a wonderful choice.
