Preheat oven to 375 degrees Fahrenheit.

Roll out dough as thinly as possible.

Prepare the cinnamon bun mixture: In a small bowl, combine butter, brown sugar, oats, and cinnamon. Sprinkle over crust. (Add extra brown sugar if desired.)

Bake for 12–15 minutes or until the crust is light brown.

Prepare the glaze: With a mixer, beat butter and cream cheese together. Add powdered sugar and vanilla, and continue beating until combined. If glaze is too thick, microwave briefly to soften it to a drizzling consistency. Drizzle over pizza.
