01 - Whisk together the flour, sugar, baking powder, baking soda, and salt in a large bowl until well incorporated.
02 - Whisk the Greek yogurt, milk, eggs, melted butter, and vanilla extract in a separate bowl until smooth and uniform.
03 - Pour the wet ingredients into the dry ingredients and stir gently until just combined. Do not overmix; a few small lumps are acceptable.
04 - Gently fold the blueberries into the batter, being careful not to crush them.
05 - Heat a nonstick skillet or griddle over medium heat and brush lightly with butter.
06 - Scoop ¼ cup of batter per pancake onto the skillet. Cook for 2–3 minutes until bubbles form on the surface and edges appear set.
07 - Flip each pancake and cook for another 1–2 minutes until golden brown and completely cooked through.
08 - Repeat with remaining batter, adding more butter to the skillet as needed between batches.
09 - Serve warm pancakes with maple syrup, additional Greek yogurt, or fresh blueberries.
