In a bowl, whisk together the flour, sugar, baking powder and salt.
Add the butter to the flour mixture and mix with either your fingertips, a pastry blender, or two knives until it forms the texture of coarse meal.
Add the milk and chocolate chips and mix gently until just incorporated (the dough may look a bit dry, but allow it to sit for a few minutes and the flour will soak up all the milk).
Place dough on a lightly floured surface and gently press into a 1″ thick circle.
Cut dough into wedges and place on a parchment lined baking sheet. Bake for 25 minutes, or until golden brown.
Move immediately to a wire cooling rack and serve.
