For the best taste and texture I recommend enjoying the rolls the same day they're made. However, you can transfer them in a sealed container and keep on the counter for 2-3 days. To store them longer, place the sealed pumpkin dinner buns in the fridge for up to 4-5 days. Any longer than that, and you'll want to freeze them: Wrap each roll in a layer of aluminum foil or plastic wrap, and store together in an airtight ziploc bag. Freeze for up to 3 months; thaw overnight in the fridge or on the counter for an hour or so.
