Prepare the Pan: Lightly grease a 9×13-inch baking dish with nonstick cooking spray.
Arrange Rolls: Place the frozen cinnamon rolls in the prepared pan. Cover with plastic wrap sprayed with cooking spray to prevent sticking.
Thaw and Rise: Choose your preferred method from the Rhodes package:
Refrigerator Method: Let the rolls thaw in the refrigerator for 8-16 hours.
Room Temperature Method: Allow them to thaw and rise at room temperature for 3-5 hours until doubled in size.
Preheat Oven: Once the rolls have risen, preheat your oven to 350°F (175°C).
Add Heavy Cream: Pour the heavy whipping cream evenly over the rolls, allowing it to soak in for about 5 minutes.
Prepare Topping: In a bowl, combine the melted butter, brown sugar, ground cinnamon, and vanilla extract. Mix until smooth.
Add Topping: Pour this mixture over the cinnamon rolls, spreading it evenly with a spatula.
Bake: Place the baking dish in the preheated oven and bake for 30-35 minutes, or until the rolls are golden brown.
Cool and Frost: Remove from the oven and let the rolls cool for about 10 minutes. Then, spread the provided cream cheese frosting over the warm rolls.
