In a large bowl, whisk together the flour, baking powder, baking soda, salt, and sugar.
2 cups flour, 2 tsp baking powder, 1 tsp baking soda, ½ tsp salt, 2 tbsp granulated sugar
Add in the buttermilk, melted butter, eggs, and vanilla. Whisk until smooth.
2 cups buttermilk, 3 tbsp melted butter, 2 large eggs, 1 tsp vanilla extract
Set batter aside while you prep the pan. Melt a pat of butter in a large skillet or griddle and heat over medium heat.
Once the butter melts and the pan is hot, whisk the batter one more time. Pour a ¼ cup of batter per pancake into the skillet. Cook on one side for approximately 1-2 minutes or until the top of the pancake has bubbles all over that start to burst.
Flip and cook for another 1 to 1½ minutes until golden brown on each side. Add more butter as needed as you make more pancakes.
