Preheat oven to 450°F (230°C). Line a baking sheet with parchment paper.

In a large bowl, whisk together flour, baking powder, baking soda, and salt.

Cut the cold butter into small cubes. Add to the flour mixture and use a pastry cutter or your fingers to work the butter into the flour until it resembles coarse crumbs.

Gradually add the cold buttermilk, stirring until the dough just comes together. Do not overmix.

Turn the dough onto a lightly floured surface. Gently pat it into a 1-inch thick rectangle.

Use a biscuit cutter or a glass to cut out biscuits. Place them on the prepared baking sheet, leaving a little space between each.

Bake for 10-12 minutes, or until the biscuits are golden brown on top.

Remove from the oven and let cool slightly before serving.
