It’s best to serve peach cobbler cinnamon rolls the day they are made, but the individual components can be prepped in advance and stored for later use. The cinnamon rolls can be made, shaped, and tightly covered the night before, then stored unbaked in the fridge for up to 12 hours. Let them come to room temperature before baking. Likewise, the peach cobbler topping can be stored in the fridge overnight and gently warmed before use.
