Sourdough Cookie Bars with Oatmeal and Chocolate Chips
The perfect one bowl, mix and bake dessert that’s sure to be a crowd pleaser! These sourdough cookie bars are delicious without being overly sweet and a great way to use up sourdough starter whether discard or fed.
When we were planning our wedding, one of the more significant disagreements Jim and I had was over the cake. He’s a cake fan and of course, a wedding should have cake was his opinion. Cake was never my favorite. I much prefer a cookie or brownie—with ice cream of course!
So, we compromised and had a 4-tier cake where the top and bottom tiers were a classic cake and the middle two layers were a beautifully displayed assortment of chocolate chip cookie bars and brownies. It was a win-win and the cookie bars and brownies froze way better than the cake to eat on our first anniversary!
Cookie Bar Perks
Growing up, chocolate chip cookie bars were the go-to dessert in my house. I had the recipe on the back of the yellow nestle tollhouse bag of semi-sweet chocolate chips memorized.
Why cookie bars instead of cookies? Because they are WAY easier and the thickness of them makes the texture even more delicious in my opinion. After many chocolate chip cookie attempts that wound up flatter than pancakes (regardless of the tips and tricks I tried), I embraced the cookie bar and it never fails me!
Recently, I wanted to take the nestle tollhouse cookie bar I grew up with to the next level and this resulting chocolate chip cookie cake does not disappoint. But then I started wondering if we could make a sourdough cookie bar to add to our repertoire for our once-a-month sourdough session.
We love this recipe for sourdough cookie bars with chocolate chips and oats. It is a great way to use up extra sourdough starter that’s either fed or discard and comes together in just a few minutes to make a delicious dessert!
Sourdough Cookie Bar Ingredients
Sourdough Starter – For this recipe either fed or discarded starter is fine. If you are looking to get started in sourdough, my favorite resource to start your own sourdough starter comes from Sandor Katz’s book The Art of Fermentation. We followed his recipe to a T about a decade ago and it’s been going strong ever since.
Flour – All-purpose flour would work well. Or if you are grinding your own fresh flour, we like to use soft white wheat berries from Azure Standard.
Baking Soda
Salt
Butter or Coconut Oil
Brown sugar or Coconut Sugar – We buy the organic brown sugar from Costco.
Cane Sugar – Our favorite is the organic cane sugar from Costco or Sucanat from Azure Standard.
Vanilla Extract
Eggs – Room temperature eggs are always best when baking.
Oats – We love the One Degree gluten free and glyphosate free oats from Costco.
Chocolate Chips
How to Make Sourdough Chocolate Chip Cookie Bars
Gather all of the ingredients and begin by creaming together the butter (or coconut oil) with the brown and white sugar in a large mixing bowl. It’s best if the butter is room temperature for this.
Once the butter and sugar are combined, mix in the eggs and vanilla.
Then stir in the sourdough starter.
Once all of the wet ingredients are mixed, add the dry ingredients (flour, baking soda, salt) to the same mixing bowl.
Stir together until all of the flour is incorporated.
Add in the oats and chocolate chips and mix until combined.
Scrape batter into a greased 9×13 baking dish.
Bake at 350°F for 30 minutes, until fully set.
Let cool before serving.
Chocolate chip cookie bars are always best served with a scoop of homemade ice cream!
Best way to store Sourdough cookie bars?
I like to keep them on the counter, covered for the first 24 hours. Then I’ll move them to the fridge for 3-5 days. These also freeze beautifully for long term storage.
