Preheat your oven to 450 degrees F.
This high heat helps achieve that golden crust.
In a large bowl, mix the flour, baking powder, baking soda, and salt.
Use a whisk for even distribution.
Add cold, cubed butter to the flour mixture.
Cut the butter in with a pastry cutter or your fingertips until the mixture resembles coarse crumbs.
Pour in the buttermilk gradually.
Stir until the dough just comes together, being careful not to overmix.
Roll out the dough to about ¾-inch thick.
Fold the dough in thirds (like a letter). Rotate 90 degrees, pat out again, and repeat the folding process 1-2 more times.
Cut biscuits using a round cutter and place them on a parchment-lined baking sheet.
Bake for 12-15 minutes until golden brown.
