Whisk together flour, sugar, baking powder, baking soda, and salt in a large bowl.

In another bowl, whisk buttermilk, eggs, melted butter, and vanilla.

Pour the wet mixture into the dry mixture. Stir gently until mostly combined with some lumps remaining.

Let the batter rest for 5 to 10 minutes.

Heat a nonstick skillet or griddle over medium heat and lightly coat with butter.

Scoop about 1/4 cup of batter onto the pan. Cook until bubbles form and edges look set, about 2 to 3 minutes.

Flip and cook for another 1 to 2 minutes until golden and cooked through.
