2 cups all-purpose flour

2 teaspoons baking powder

1/2 teaspoon baking soda

1 teaspoon sugar

8 tablespoons unsalted butter, melted (see page 12 for how to melt butter)

Adjust oven rack to middle position and heat oven to 450 F. Line rimmed baking sheet with parchment paper.

In large bowl, whisk flour, baking powder, baking soda, sugar, and salt until combined. In liquid measuring cup, use fork to stir buttermilk and melted butter until butter forms small clumps.
