These are a great way to use up excess sourdough discard starter! They’re soft and thick, with melty chocolate chips and a hint of cinnamon.
Feel free to substitute the chocolate for raisins and make sourdough oatmeal raisin cookies, though!
You can make and bake these chewy cookies all in one day or give them an overnight ferment before baking.
Sourdough Oatmeal Cookies with Chocolate Chips
Ingredients
142g (1/2 cup + 2 Tbsp) unsalted butter
100g (1/2 cup) soft brown sugar
50g (1/4 cup) granulated sugar
100g (1/2 cup) discard sourdough starter
1 large egg
1 1/2 teaspoons vanilla paste or vanilla extract
125g (1 cup*) all-purpose flour
3/4 teaspoon salt
1/2 teaspoon baking soda
1/2 teaspoon ground cinnamon
120g (1 1/3 cup) rolled oats
160g (1 cup) semi-sweet chocolate chips
Instructions
In a medium saucepan, melt the butter over medium heat. Avoid using a dark pan as you will struggle to see the caramelization of the butter and run the risk of burning it.
Once melted, let it cook further for around 3-4 minutes, stirring occasionally until the milk solids in the butter have caramelized into a golden amber-brown color and the butter has a nutty aroma.
Pour the melted butter into a large mixing bowl, including all the caramelized brown bits at the bottom of the pan, and allow it to cool down for 10 minutes.
In a small separate bowl whisk together the flour, oats, cinnamon, salt, and baking soda and set it aside.
Once the butter has cooled, whisk in the brown sugar, granulated sugar, sourdough starter egg, and vanilla.
Stir the dry ingredients into the wet ingredients using a rubber spatula or wooden spoon, followed by the chocolate chips.
Cover the dough and chill for at least 2 hours or overnight. For easier rolling, you can chill the dough for 30 minutes until slightly stiffened, then roll it into balls and chill the cookie dough balls for the remainder of the time.
When baking, line a cookie sheet with parchment paper. Preheat the oven to 350F/180C.
Roll a tablespoon and a half of dough per cookie into a ball. Place the cookie dough balls around 2 inches/ 5 cm apart on the prepared baking sheets.
Bake the cookies for 10-12 minutes until the cookies are golden brown around the edges but still a little soft. It's best to underbake them than over-bake them. Underbaking gives a great chewy texture, while over-baking can make them too cakey.
Let the cookies cool for 5 minutes on the baking sheet before placing them on a wire rack to cool further.
