Place a bowl onto a scale and measure out the flour and sugar. Then add the baking powder, baking soda and salt. Using a whisk, blend the ingredients together well. This can be made in advance and stored in an airtight container.
Crack the eggs into a bowl and whisk until fluffy. Add the buttermilk, melted butter and vanilla. As these are simple and classic pancakes, there is no extra flavorings, but vanilla extract can be left out or almond extract can be substituted.
Add the liquid ingredients to the dry ingredients and fold the mixture together until a batter is formed. A few lumps are ok.
