The Best Flaky Buttermilk Biscuits

Preheat the oven to 450 degrees F. Line a baking sheet with parchment paper.

Whisk together the flour, baking powder, baking soda, sugar and salt in a medium bowl. Rub 2 tablespoons of the cold butter into the flour with your fingertips until completely absorbed. Work the remaining 8 tablespoons of cold butter into the flour with your fingertips until pea-size bits of butter remain. Use a rubber spatula to stir the buttermilk into the flour until the mixture comes together into a shaggy dough. (Don’t overmix the dough.)

Lightly flour a cutting board or work surface, turn the dough out onto it and pat into a rectangle. Fold the dough in half and pat again into a 1/2-inch-thick rectangle. Then fold the dough in thirds, as if folding a letter, and pat to an even thickness. Cut out biscuits with a 2 1/2-inch round biscuit cutter and put on the prepared baking sheet. Press together the remaining scraps of dough. Pat out and fold the dough into thirds again and cut out more biscuits. Brush the biscuit tops with buttermilk.

Bake until the tops are lightly browned, about 15 minutes. Cool on the pan at least 5 minutes. Serve warm or at room temperature.
