Preheat oven to 425 degrees. Spray CAULIPOWER Cauliflower Crust lightly with cooking spray, then sprinkle on the sugar. Place the crust directly onto the middle rack of the oven and cook until the edges start to brown, about 10-12 minutes. Remove the crust from the oven and let cool.
Once the crust has cooled, spread the whipped topping onto the crust. Add the halved SkinnyDipped chocolate peanut butter cups and assorted Halloween candy. Garnish the pizza with sprinkles. Enjoy!
