In a large bowl, mix the flour, baking powder, baking soda and sugar. In a separate bowl, mix the buttermilk, eggs melted butter, and vanilla extract.
Pour the buttermilk mixture over the dry ingredients and mix just until the flour is hydrated. Lumps are ok.
Spray a large skillet or a griddle with baking spray or butter and warm over medium heat.
Use a spoon or a squeeze bottle to pour the batter and reduce heat to medium-low.
Once you notice bubbles on the surface and that the batter changed from shiny to mat use a small spatula or a form to flip the pancakes, and cook for an additional one minute.
Remove from heat and repeat with the rest of the batter. Serve immidiatley.
