In a large mixing bowl, whisk together the flour, sugar, baking powder, and salt.
Using a pastry blender or your fingertips, cut in the butter until the mixture resembles coarse crumbs.
Add the milk and stir until a dough forms.
Turn the dough out onto a lightly floured surface and knead gently for 1-2 minutes, until it comes together into a smooth ball.
Divide the dough into 8 equal pieces and shape each one into a disc about 1/2-inch thick.
Heat a large skillet over medium-high heat and grease it lightly.
Place the discs of dough in the skillet and cook for 3-4 minutes per side, until golden brown and cooked through.
Serve warm with butter or jam, if desired.
