Put the rounds of cookie dough all over a greased 12 inch pizza pan.
Flatten the rounds out with your hands until you get a nice even layer.
Bake in oven until cookie crust because lightly browned. Around 12-15 minutes.
Cool the crust completely before adding on the cream cheese mixture.
For the Cream Cheese Mixture:
Beat cream cheese, vanilla, and sugar together until smooth.
Add in half of the whipped topping and beat mixture for a minute more.
Fold in the rest of the whipped topping. Blend.
Scoop about half of the mixture onto cooled pizza crust and spread evenly.
Use the berries to create a flag on the pizza. I outlined mine with blueberries and then alternated between raspberries and strawberries for the stripes.
Use remaining cream cheese mixture to pipe in white stripes as well.
