Preheat oven to 375 degrees and spray a 9x13 inch baking dish with cooking spray.
Lay the refrigerated rolls into the baking dish and set icing aside to let it come to room temperature.
In a medium bowl, beat eggs, then beat in the cream, cinnamon, and vanilla. Pour over rolls and sprinkle with nuts. Drizzle syrup over the top.
Bake for 20-25 minutes. Cool for 15 minutes, then drizzle icing over the top.
Notes
If the rolls do not fit in one layer or you do not want individual "servings." simply cut the rolls into pieces and lay the pieces in a single layer in the bottom of the dish. Then proceed as the recipe directs. Recipe Source: From my friends over at RecipeLion.com!
