Preheat the oven to 450°F and line a baking sheet with parchment paper.
Use a whisk mix the all purpose flour, baking powder, salt and baking soda in a large mixing bowl.
Cube the butter and cut it into the dry ingredients using a fork or pulse with a good processor. You want the mixture to be crumbly and resembles peas.
Pour in 1 cup cold buttermilk. Stir just until the crumbs are thoroughly moistened. Add up to 1/4 cup additional buttermilk, if needed. The dough shouldn't be overly wet, but slightly sticky.
Roll or pat out on a lightly floured work surface about 3/4-inch to 1-inch-thick. Cut into rounds using a 2-inch cookie cutter dipped in flour. I cut straight down and pull up, rather than twisting the cutter into the dough to cut it. Re-roll any scraps and repeat.
Place biscuits 2 inches apart on the baking sheet that is oiled. I actually prefer to use my pizza stone!
Bake biscuits at 450°F for 13-15 minutes until lightly golden and puffed. (You can broil at the end of baking to make the tops more golden brown, if desired.)Enjoy!
