Preheat your oven to 375 degrees F. Open refrigerated cinnamon rolls and set icing aside. Rip cinnamon roll dough into small pieces and place in a greased baking dish.
In a separate bowl whisk together eggs, heavy whipping cream, vanilla, pumpkin pie spice, and pumpkin puree.
Pour egg mixture over cinnamon rolls and bake for 30 minutes. Or until fully cooked. Allow to cool slightly then drizzle on icing.
