Heat over to 350 degrees. Use a nonstick pizza pan, or spray your pizza pan with nonstick cooking spray.
Open the sugar cookie dough, place it in the pizza pan, and start spreading with your hands. You want to spread the dough out into a circle that fits inside the pan. You can smooth it out and patch the areas that you need to with dough – the dough is going to even out when you bake.
Bake according to the package instructions – approximately 12 – 14 minutes or until the edges are brown. Let cool for at least 20 minutes.
While the cookie pizza is cooling, make the vanilla frosting.
Use a knife to spread the frosting out onto the cookie, completely covering the cookie top. They’ll put dots down and then add circles around the dots.
Place gel dots down immediately, and add circles around the dots. Using a toothpick, drag outward from the center to create the fireworks pattern.
Vanilla Frosting
Place 2 cups of confectioners’ sugar in a bowl. Add 2 tablespoons butter, 2 tablespoons milk, and ½ teaspoon vanilla extract to the sugar. Stir to combine.
The mixture should be frosting consistency; if it isn’t, add a touch of milk and keep stirring until it reaches desired consistency.
