01 - Whisk together the sourdough discard, milk, eggs, melted butter, and vanilla in a large mixing bowl until smooth and fully incorporated.
02 - Combine the flour, sugar, baking powder, baking soda, and salt in a separate bowl, ensuring even distribution of leavening agents.
03 - Add the dry ingredients to the wet mixture and gently fold until just combined. Stop mixing when a few lumps remain to avoid tough pancakes.
04 - Heat a nonstick skillet or griddle over medium heat and lightly grease with butter or cooking oil.
05 - Pour ¼ cup of batter per pancake onto the preheated skillet. Cook until bubbles form across the surface and edges appear set, approximately 2–3 minutes.
06 - Carefully flip each pancake and cook for an additional 1–2 minutes until golden brown and completely cooked through.
07 - Repeat the cooking process with remaining batter, applying grease to the pan as needed between batches.
08 - Serve pancakes warm with maple syrup, fresh fruit, or your preferred toppings.
