Step 1

Combine the flour, sugar, baking soda, baking powder, and salt in a medium bowl and stir using a balloon whisk to combine.

Step 2

Add the wet ingredients: buttermilk, butter, and vanilla, and mix until smooth. Do not over mix; otherwise, the waffles will be heavy when cooked. Let the batter rest at room temperature for 10 minutes.

Step 3

Preheat a waffle iron according to the manufacturer's instructions.

Step 4

Spray the waffle iron with non-stick cooking spray. Pour the batter into the waffle iron and cook according to the manufacturer's instructions, usually for 2 to 3 minutes. PRO TIP: your waffles most likely be ready when you don't see more steam coming out of the side of the waffles maker.

Step 5

Place in a 200º F (95º C) oven to keep waffles warm while you finish with the rest of the batter. I recommend placing the waffles directly on the oven rack in a single layer; this way, the heat will circulate properly, and the waffles will retain their crisp texture.
