To a large bowl add 440 grams of flour, 2 tsp salt (10g), 1/2 tsp baking soda, and 1 tsp baking powder. Mix, and set aside.
In a small bowl measure out 250 grams of sourdough discard (1 cup), 2 room temperature eggs, and 2 tsp vanilla. mix, and set aside.
Cube 1 cup cold butter then add it to a bowl with 1 cup brown sugar, 1 cup white granulated sugar, and 2 teaspoons apple cider vinegar
( you can add it to a stand mixer with a paddle attachment) With your hands combine the butter, apple cider vinegar, and the sugars together to form little crumbs. Next, add the chocolate chips to the butter and sugar mixture and combine it together.
Add the dry ingredients and continue to mix them either by hand or in a stand mixer.LAstly, add the wet ingredients to the large bowl and mix only to combine the ingredients. It is very important to not over mix the sourdough cookie batter as it can result in a cake-like cookie (I used my hands to combine it, you can use the stand mixer) Line a cookie sheet with parchment paper then use an ice cream scooper to shape the cookies and line them 2 inches apart. This makes approximately 21 cookies. Cover with seran wrap and put them in the freezer while the oven preheats to 375. Bake for 15-17 minutes. Sprinkle some course salt on top of the sourdough discard chocolate chip cookies while they just come out of the oven ( the salt is optional, of course) Let them cool down on a wire rack, and Enjoy them with a glass of cold milk!
