Preheat oven to 475°. Prepare baking sheets with parchment paper to prevent sticking or use a non stick baking sheet.

In the smaller mixing bowl, whisk together the flour, corn starch, salt, and baking soda. Cut the stick of butter into smaller pieces. In the larger mixing bowl, combine the butter, sugar, brown sugar, egg, and vanilla extract

Gently stir the dry ingredients into the larger bowl with the butter/egg/sugar mixture. Add in chocolate chips and mix gently until fully combined.

Using a full size spoon (tablespoon), make cookie dough balls and place them on the baking sheet.

Bake for 6-7 minutes or until the tops of the cookies get golden/brown.
