Step 1: Prepare the Oven
1. Preheat the Oven: Preheat your oven to 350°F (175°C) and grease a 12-inch pizza pan or a baking sheet.

Step 2: Make the Cookie Crust
1. Prepare the Dough: In a large bowl, break up the sugar cookie dough and mix in the flour until well combined.
2. Spread the Dough: Press the dough evenly onto the prepared pizza pan to form a crust, making sure to create a slight edge around the perimeter.
3. Bake: Bake in the preheated oven for 10–12 minutes, or until the edges are lightly golden. Remove from the oven and let it cool completely.

Step 3: Prepare the Cream Cheese Filling
1. Mix Filling: In a medium bowl, beat the softened cream cheese, powdered sugar, and vanilla extract until smooth and creamy.
2. Fold in Whipped Topping: Gently fold in the whipped topping until fully combined.

Step 4: Assemble the Dessert Pizza
1. Spread the Filling: Once the cookie crust has cooled, spread the cream cheese filling evenly over the crust.
2. Add Cherry Topping: Spoon the cherry pie filling over the cream cheese layer, spreading it out evenly.

Step 5: Serve
1. Chill: For best results, refrigerate the dessert pizza for at least 1 hour before slicing.
2. Garnish and Serve: Optionally, garnish with fresh cherries or whipped cream before serving. Slice into wedges and enjoy!
