Preheat oven to 375 degrees. Prepare a 14 inch cake pan or a pizza pan with oil or non-stick spray.
In a large bowl or stand mixer, whisk butter, white sugar, coconut sugar, and vanilla until creamy.
In a second bowl, whisk flour, salt and baking soda until well combined. Pour the flour mixture into the wet batter gradually, mixing until well blended. Stir in chocolate chips.
Spread dough into your prepared pan and cook for 20-22 minutes.
If you are planning to frost your cookie, make sure you allow the cookie to cool completely before frosting. The frosting will come together in about 5 minutes while the cookie is baking.
