Preheat oven to 350 degrees F. Spray cups of a 12-cup mini muffin pan with nonstick cooking spray.
On a lightly floured surface, unroll dough and separate into 2 rectangles. Gently pinch any open seams together with your fingers.
Stir together sugar and cinnamon in a small bowl; sprinkle evenly over rectangles. Roll up jellyroll style into 2 logs. Cut each log into 6 slices and place slices into muffin pan cups.
Bake for 10-12 minutes, or until rolls are risen and lightly golden.
Stir together powdered sugar, milk and vanilla in a small bowl until smooth. Drizzle glaze over warm rolls.
