This make-ahead cinnamon roll casserole is assembled the night before and baked fresh on Christmas morning, creating a soft, gooey, caramelized breakfast that tastes like effort but takes almost none. It’s the perfect low-stress holiday breakfast that lets you enjoy the morning with your family.
Do not over-soak the rolls beyond 24 hours. Use full-fat heavy cream for best texture. Let the casserole rest 5-10 minutes before adding icing to prevent it from melting. For a dairy-free version, use plant-based butter and full-fat coconut cream. For gluten-free, use gluten-free refrigerated cinnamon rolls.
