Best served warm, but leftovers keep well at room temperature (wrapped or in an airtight container) for 2-3 days. To freeze, wrap individual pieces in plastic and foil, then transfer to a freezer bag for up to 2 months. Thaw at room temperature or reheat in microwave or in a 300°F oven. Variations: Add chopped nuts or diced apples for extra flavor, use biscuit dough instead of rolls, swap in pumpkin pie spice, or finish with a homemade glaze if your rolls came without icing.
