Preheat oven to 350 degrees F. Grease a 14” pizza pan (with no holes), set aside. If you only have a pizza pan with holes, cover it in aluminum foil and lightly grease.
In a medium bowl, combine flour, baking soda and salt. Set aside.
In the bowl of a standing mixer fitted with the paddle attachment, or in a large bowl using a hand-held mixer, beat butter, granulated sugar, and brown sugar until light and fluffy (1-2 minutes).
Add vanilla and eggs and beat until fluffy, about 1 minute.
Add dry ingredient mixture and beat until combined.
Add chocolate chips and stir until evenly distributed.
Spread the cookie dough into a 12-13” circle on the prepared pizza pan. Be sure to leave a 1 to 1 ½” border between the edge of the cookie and the outside edge of the pan.
Bake in the preheated oven for 15-20 minutes or until the top is golden brown and set.
Remove from oven and set the cookie cake in the baking pan on a wire rack to cool completely.
Once cooled, transfer the cookie cake to a serving platter. Decorate and let sit until the frosting hardens.
