Preheat the oven to 350°F. Grease a 9x13 baking dish with shortening. Use a smaller casserole dish if you want taller rolls.
Place unwrap the cinnamon rolls, setting aside the glaze topping for later, and arrange them in a single layer in the prepared pan.
Pour the cream over the tops and around the rolls.
In a small microwave-safe bowl, melted the brown sugar and then whisk in the cinnamon and nutmeg. Spoon over the top of each roll.
Cover tightly with foil and bake for 30 minutes or until the center roll passes the toothpick test.
Remove and allow to cool while you make the topping.
In a small microwave-safe bowl, combine the butter and cream cheese. Heat in the microwave for 30-40 seconds, or until you can stir it together smoothly. Add the powdered sugar, vanilla, additional salt and two reserved glazes. Stir until no streaks remain.
Drizzle over warm rolls. Serve immediately.
