Proof your dough in a rectangle shaped dish rather than a bowl so it proofs already in the shape that you're about to roll it out into.
To prep these cinnamon rolls the night before and bake fresh in the morning:
After cutting the rolls and placing them in a greased baking dish, cover and refrigerate overnight (8–12 hours). The rolls will rise slowly in the fridge but will not double — this is normal.
In the morning, remove the rolls from the refrigerator and let them sit at room temperature for 45–75 minutes, until puffy and noticeably risen. (If your kitchen is cold, place them in an oven that’s turned off with the light on.)
Once risen, pour the heavy whipping cream over the rolls and bake as directed. Frost and enjoy warm.
