05 - Pour the wet ingredients into the dry ingredients and gently mix until just combined, avoiding overmixing.
06 - Carefully fold in the semi-sweet chocolate chips to distribute evenly.
07 - Turn the dough onto a lightly floured surface and pat into a 1-inch thick round.
08 - Cut the dough into 8 wedges and arrange them spaced apart on the prepared baking sheet.
09 - Brush the tops of each wedge lightly with extra milk to promote a golden crust.
10 - Bake for 16 to 18 minutes until golden brown and cooked through.
