Step 1: Prepare the Pizza Dough

• Preheat your oven to 350°F (175°C). Line a pizza pan or a large baking sheet with parchment paper.
• On a lightly floured surface, roll out the refrigerated sugar cookie dough into a large circle (about 12 inches in diameter) to form the pizza crust.
• Carefully transfer the rolled-out dough to the prepared pizza pan and press it down to fit.

Step 2: Make the Cinnamon Topping

• In a small bowl, combine the softened butter, brown sugar, granulated sugar, and ground cinnamon. Mix until well combined and creamy.
• Spread the cinnamon mixture evenly over the cookie dough crust.

Step 3: Bake the Dessert Pizza

• Place the pizza in the preheated oven and bake for 20-25 minutes, or until the edges are lightly golden and the center is set.
• Remove from the oven and let it cool in the pan for about 10-15 minutes before slicing.

Step 4: Prepare the Cream Cheese Icing

• In a mixing bowl, beat the softened cream cheese and butter together until smooth and creamy.
• Gradually add the powdered sugar and vanilla extract, mixing until well combined. If the icing is too thick, add milk a tablespoon at a time until you reach your desired consistency.

Step 5: Serve

• Once the cinnamon dessert pizza has cooled, drizzle the cream cheese icing over the top.
• Cut into wedges and serve warm or at room temperature.
