Heat oven to 350 degrees. Line a pizza pan (or a cookie sheet) with parchment paper and set it aside.
Add cookie dough to the pizza pan and place a piece of parchment paper on top. With a rolling pin, roll dough, creating a circle.
Remove top parchment paper and bake cookie dough crust in preheated oven for 20 minutes.
Remove pizza crust from the oven and let cool completely.
While crust is cooling, add cream cheese, heavy cream, butter, and vanilla in a large mixing bowl, mix with an electric mixer, slowly add in powdered sugar, and continue to mix until you have a smooth frosting texture.
Spread cream cheese mixture over the top of pizza cookie crust.
Next, cover the cream cheese mixture with mix cookie crumbs.
Heat marshmallow cream for 20 seconds in a microwave-safe bowl and then drizzle over pizza, creating a messy spider web effect.
Now add in candy eyes wherever you like in the spider web.
Slice dessert pizza and enjoy this easy dessert!
