Preheat the oven to 350°F (180°C). Line two baking sheets with parchment paper.
In a large bowl, mix butter with both sugars until creamy.
Add salt, milk and vanilla extract and mix to combine.
Gently incorporate flour, rolled oats and baking powder.
Fold in chocolate chips.
Using an ice cream scoop, take equal portions of dough and place on the prepared baking sheets, 1 inch (2.5 cm) apart.
Flatten slightly with the back of the scoop.
Bake for 8-9 minutes until slightly golden on the edges. Let the cookies cool on the baking sheets until the cookies are firm enough to remove, probably another 5 minutes. Cool completely on a wire rack. Enjoy!
