In a large bowl, whisk together the flour, sugar, baking powder, baking soda, and salt.
Lightly whisk the eggs, then add the eggs, buttermilk, melted butter and vanilla to the dry ingredients.
Whisk until you have a thick, but pourable batter. If you want thinner pancakes you can add a bit more milk.
Stir in the sprinkles.
Let the batter rest for 10 minutes.
Preheat your electric or stovetop griddle to medium heat. It is ready when you sprinkle a bit of water on the surface and it sizzles and evaporates right away.
Lightly butter the griddle, then pour the pancake onto the hot surface. I use 1/3 cup measuring cup, but you can make them bigger or smaller as you like.
Let the pancakes cook for about 5-7 minutes, or until the edges are starting to set and you begin to see bubbles on the surface.
Flip the pancakes and cook a few mintues more then remove to a serving plate to serve.
