Begin by heating up your waffle iron and greasing it if you need to.
In a large bowl, whisk flour, sugar, baking powder and salt. Make a well in the center, and pour in buttermilk, eggs, melted butter and vanilla. Mix until everything is fully combined without over-mixing. Let the batter rest for two minutes. Every waffle iron is different size wise so this may be different for everyone - but with my waffle iron, I use about 1/2-3/4 cup of batter per waffle to get a perfect, full waffle. Place waffles on a wire rack in a single layer and repeat this process with the remaining batter.*
Buttery Golden Buttermilk Waffles are best served immediately and eaten the same day.
* After each waffle is made, place them on a wire rack in a single layer instead of stacking them so they stay nice and crispy on the outside.
