Preheat the oven to 425°F (218°C).
In a large mixing bowl, whisk together the flour, baking powder, baking soda, and salt.
Using a pastry cutter or a fork, cut the chilled butter into the flour mixture until it resembles coarse crumbs.
Pour the buttermilk into the center of the mixture by making well.
Mix it now until just combined, be careful not to make the dough hard.
Knead dough gently for a few seconds onto a lightly floured surface.
Use a rolling pin to roll out the dough to a thickness of about 1/2 inch.
Use a biscuit cutter or a sharp-edged cup to cut out biscuits and place them on a baking sheet lined with parchment paper or coated with cooking spray.
Usually, it takes 12-15 minutes in baking or you go until the biscuits are golden brown.
