Preheat the oven to 450°F, and prepare a baking sheet or 9-inch baking dish by lining it with parchment paper.
Place the flour, baking powder, baking soda and salt in a food processor. Pulse a few times to combine.
2 cups (240 g) all-purpose flour, 2 teaspoons baking powder, ½ teaspoon baking soda, ½ teaspoon salt
Add the cubed butter, and pulse a few more times just until the mixture resembles coarse cornmeal.
½ cup (113 g) unsalted butter
With the food processor still running, slowly drizzle in the buttermilk just until the dough holds together when pressed. It should be sticky or wet.
½ to ¾ cup (113 - 170 mL) buttermilk
Turn the dough out onto a lightly floured surface, and pat into a flat rectangle.
Fold the dough in half, gently pat into a rectangle again. Repeat this step 4 to 5 times. These folds are creating layers in the dough.
Shape dough into a rectangular shape about ½ - ¾ inch thick. Use a biscuit cutter and press down firmly and bring the biscuit cutter straight up. Do not twist. Repeat to cut out 5-6 biscuits.
Place biscuits on the prepared baking sheet or dish. Bake for 9-13 minutes or until the tops are golden brown.
