Step 1

Preheat a waffle iron to medium-high.

Step 2

In a large bowl, whisk together the flour, sugar, baking powder, baking soda and salt.

Step 3

In a medium bowl, whisk together the buttermilk, eggs and vanilla. Whisk the buttermilk mixture into the flour mixture until a batter is formed. Whisk in the butter until incorporated, being careful not to overmix the batter.

Step 4

Spray both sides of the preheated waffle iron with nonstick cooking spray. Pour in enough batter to lightly cover the surface of the iron, about 1/3 to 3/4 cup, depending on its size. (Take into consideration that the batter will spread once the lid is closed.) Close the iron and cook until the waffles are a deep golden brown and slightly crisp, about 5 minutes. Repeat with the remaining batter. (If the waffle iron has a well-seasoned or nonstick surface, it may not be necessary to spray it between each batch.)

Step 5

Serve the waffles immediately with butter, syrup, jam, berries or yogurt.
