01 - In a large mixing bowl, whisk together the sourdough discard, milk, eggs, melted butter, and vanilla until smooth and fully combined.
02 - In a separate bowl, combine the flour, sugar, baking powder, baking soda, and salt until evenly distributed.
03 - Add the dry ingredients to the wet mixture and gently fold until just combined. Do not overmix; a few small lumps are acceptable and will yield tender 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 skillet. Cook until bubbles form on the surface and edges appear set, approximately 2–3 minutes.
06 - Flip each pancake and cook for an additional 1–2 minutes until golden brown and completely cooked through.
07 - Repeat with remaining batter, greasing the pan as needed between batches.
08 - Serve warm pancakes with maple syrup, fresh fruit, or your preferred toppings.
