This gooey, pull-apart casserole transforms canned cinnamon rolls into a warm, shareable feast. It is perfect for lazy weekend mornings, holiday brunches, or feeding overnight guests with minimal effort. The result is a comforting, custardy bake with a caramelized cinnamon-sugar topping, finished with a sweet icing drizzle.
For make-ahead, assemble the unbaked casserole, cover, and refrigerate overnight. Bake as directed, adding 5-10 minutes if starting cold. Leftovers reheat well. For a lighter version, use milk instead of cream and reduce the brown sugar topping.
