Heat-treat the flour by baking it briefly, then let it cool completely before using to ensure safety and proper texture.
Cream softened butter with both sugars until light and fluffy to build a smooth and rich base for the dough.
Mix in milk and vanilla extract gradually to achieve a balanced, creamy consistency without making it too loose.
Add the dry ingredients slowly and mix gently until a soft dough forms without overworking it.
Fold in chocolate chips and any optional mix-ins evenly so each bite has a consistent flavor.
Chill the dough briefly if you prefer a firmer texture that is easier to scoop and serve.
