1 stick cold salted butter
2 1/2 cups flour
2 tablespoons baking powder
1 teaspoon salt
1 cup buttermilk
Preheat oven to 425 degrees. Combine the butter, flour, salt, and baking powder into a food processor. Pulse until crumbly. Pour into a bowl. Add buttermilk and mix by hand. Turn onto a floured surface. Press to 1/2 inch thick. Try to manipulate the dough as little as possible. Cut into rounds with a cookie cutter or the rim of a glass. Place onto a greased baking dish. The edges of the biscuits should touch. Bake for 12-13 minutes. Top with melted butter if desired.
This makes 12-13 biscuits. They freeze really well from the circle but unbaked state. To use them, do not thaw prior to cooking. Just cook frozen. Start at 475 degrees for 5 minutes then finish as 425 degrees for 10 minutes.
