Place the flour, baking powder and salt into a food processor and pulse a few times to combine. Add the butter and pulse until the dry ingredients and the butter are mostly combined. (Alternatively, cut the butter into the dry ingredients with a pastry cutter.) Drizzle in the milk and pulse (or stir) just until the dough comes together. Do not over mix.
Using a regular table spoon, or large spoon, drop spoonfuls of the mixture onto baking trays and bake until nice golden brown, 20 to 25 minutes. If desired, brush with melted butter after you remove them from the oven.
