Prepare the crescent roll base:
Preheat your oven to 375°F (190°C). Roll out the crescent dough onto a parchment-lined baking sheet. Press the seams together to create a smooth, even surface.

Bake the crust:
Bake for 8–10 minutes, or until the dough is golden and cooked through. Remove from the oven and let it cool slightly.

Make the cinnamon sugar topping:
In a small bowl, mix the granulated sugar and cinnamon.

Butter and sprinkle:
Brush the melted butter evenly over the baked crescent roll crust. Then, sprinkle the cinnamon sugar mixture across the surface.

Prepare the glaze:
In a separate bowl, whisk together the powdered sugar, milk, and vanilla extract. Adjust the milk quantity to reach your desired glaze consistency.

Drizzle and finish:
Drizzle the glaze over the cinnamon sugar topping. Slice the pizza into squares or triangles and serve.
