Step 1

Heat oven to 425 degrees F. Line a rimmed baking sheet with parchment paper and lightly grease with cooking spray.

Step 2

In a large bowl, whisk together the dry ingredients.

Step 3

In a 2-cup liquid measure or small bowl, stir together the chilled buttermilk and melted butter until the butter forms small clumps and the mixture looks curdled.

Step 4

Stir the buttermilk mixture into the flour mixture with a rubber spatula just until the ingredients are incorporated and the mixture slightly pulls away from the edges of the bowl.

Step 5

Using a greased 1/4-cup measure or large #20 cookie scoop, portion the dough and drop them onto the prepared baking sheet, spacing about 1 1/2 inches apart.

Step 6

Bake the biscuits until the tops are golden brown, 13 to 15 minutes. Remove from the oven, brush with additional melted butter. Serve warm.
