Preheat the oven to 450 degrees F (230 degrees C). Line a cookie sheet with parchment paper and spray with nonstick cooking spray. Set aside.
Mix flour, baking powder, baking soda, salt, and sugar in a large bowl. Cut in cold butter. Add buttermilk and stir until just combined. Do not overmix.
Place on a floured surface and pat into a circle about 1 inch thick. Cut biscuits using a 3.5 inch biscuit cutter. Arrange 6 biscuits in a circle, 1 in the center, edges touching.
Bake in the preheated oven until bottoms are browned and tops are starting to brown, 11 to 14 minutes.
