Mix in a bowl the flour, sugar and baking powder. Add the cold butter cut in cubes to the mixture.
Rub it into the flour mixture using your fingertips until the mixture resembles breadcrumbs.
Add the egg, milk and vanilla extract. Using a spatula or your hands, mix everything together until it becomes dough.
Add the chocolate chips and incorporate into the dough.
Using a spoon, place 9-12 balls (no need for a perfect shape here) of the mixture into a lined baking tray.
Bake for 15-20 minutes or until golden brown in a preheated oven to 180°C/350°F. Allow them to cool down for a couple of minutes, then turn them out onto a wire rack.
