01 - Whisk together sourdough discard, milk, eggs, melted butter, and vanilla in a large mixing bowl until smooth and fully incorporated.
02 - Combine flour, sugar, baking powder, baking soda, and salt in a separate bowl, ensuring even distribution of leavening agents.
03 - Pour dry ingredients into wet mixture and fold gently until just combined. Stop mixing when small lumps remain—overmixing yields tough pancakes.
04 - Heat nonstick skillet or griddle over medium heat until evenly hot. Lightly coat surface with butter or cooking oil.
05 - Pour ¼ cup batter per pancake onto preheated surface. Cook until bubbles form across surface and edges appear set, approximately 2-3 minutes.
06 - Turn pancakes carefully and cook second side until golden brown and completely set, about 1-2 minutes longer.
07 - Continue cooking remaining batter, adding grease to pan as needed to prevent sticking. Adjust heat if pancakes brown too quickly.
08 - Serve pancakes immediately while hot, accompanied by maple syrup, fresh berries, or preferred toppings.
