Sourdough oatmeal cookies
Chewy sourdough oatmeal cookies made with discard, brown sugar, cinnamon, oats, and optional raisins or chocolate.
Sourdough oatmeal cookies are a discard recipe that actually benefits from the starter. The acidity balances brown sugar and keeps the cookie chewy.
why this works
Discard adds moisture and a quiet tang. Resting the dough gives the oats time to hydrate, which makes the final cookie thicker and less cakey.
