Combine your flour, sugar, baking powder, and salt.
Separate your egg yolks into a large bowl and egg whites into a smaller bowl. Add your buttermilk, vanilla, and oil to the egg yolks and beat until combined. Beat the egg whites until foamy, then set aside.
Pour the wet ingredients into the dry ingredients, whisk until combined. Fold the foamy egg whites into the batter. Pour 1/3 cup of batter at a time onto a hot, greased griddle (usually over medium-high heat at first, then reduce to medium).
Cook the pancakes until bubbling on one side, then flip and cook until fluffy and firm, about 2 minutes. Drizzle maple syrup over a big ol’ stack of pancakes and enjoy!
