First, preheat your oven to a cozy 375°F (190°C). Grab your favorite pizza pan!
Gently unroll the crescent roll dough. Arrange the triangles on your pizza pan so their points meet in the center. Overlap the edges slightly and press them together firmly to create a nice, even pizza crust.
Lightly brush the melted butter all over your crescent roll crust. This adds a lovely rich base!
In a small bowl, whisk together the granulated sugar and ground cinnamon until well combined. Sprinkle this fragrant mixture evenly over your buttered dough.
Pop your pizza into the preheated oven. Bake for about 12-15 minutes, or until the crust is beautifully golden brown and cooked through.
While your pizza is baking, quickly whisk the powdered sugar, milk, and vanilla extract together in a separate bowl until you have a smooth, pourable glaze.
Once the pizza is out of the oven, generously drizzle the warm glaze all over it. Slice into individual pieces and serve immediately to enjoy this warm, delightful treat!
