Preheat the oven to 450°F (232°C).

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

Add the cold, cubed butter to the flour mixture and cut it in until it resembles coarse crumbs.

Pour in the buttermilk and stir gently until just combined.

Turn the dough onto a floured surface and press it into a rectangle about 1 inch thick.

Use a biscuit cutter to cut out rounds from the dough.

Place the biscuits on a baking sheet lined with parchment paper, slightly touching.

Bake in the preheated oven for 12-15 minutes until golden brown.

For extra buttery flavor, brush melted butter on top of the biscuits immediately after baking.
