Pre-heat oven to 375F/190C. Spray or grease and flour an 8 inch square baking dish or round skillet.
In a large bowl stir together the peaches, ¾ cup / 150g of sugar, corn starch and lemon juice, pour into the prepared pan.
Whisk together the flour, 2 tablespoons / 25g of sugar , baking powder and ¼-½ teaspoon of salt. Cut in the cold butter until coarse crumbs appear. Stir in the milk, start with 8 tablespoons / 120ml if too dry add more milk. Using a large ice cream scoop or heaping tablespoons, drop mounds on the fruit in the pan, slightly flatten the mounds with your hands, sprinkle with the remaining sugar on top.
Bake until golden, thick and bubbly, approximately 40-45 minutes, if it starts to brown too much after 30 minutes, then cover with a piece of foil tent style over the pan and continue to bake. Let cool on a wire rack and serve with a scoop of vanilla ice cream. Enjoy!
Notes
Storage: Leftovers can be stored covered in the refrigerator for up to 3 days. Reheat in the oven at 350F / 180C until warmed through, or microwave individual portions for a minute or two. The topping will soften in the fridge but will crisp back up a little in the oven.
