Add the flour, baking powder, salt, and butter into a food processor and pulse until mixture is crumbly (alternatively, this can be done in a bowl with a pastry cutter).
Add 1-1/4 cup buttermilk and stir with a fork just until flour is moistened. Add an additional ~1/4 cup buttermilk if mixture is too dry and crumbly.
Turn dough out onto a lightly floured surface. Roll or pat dough out to ¾-inch thickness. Cut with a 2- or 2½-inch biscuit cutter (push the biscuit cutter, don't twist!). Place biscuits on a baking sheet.
Bake at 450°F for 10-14 minutes or until golden. Remove from the oven and brush with melted butter. Makes 8-10 biscuits depending on the size biscuit cutter you use.
