Leftovers only keep for about 1 day. These pumpkin scones taste best the day they are baked. If you do have leftovers, store them in an airtight container at room temperature for up to 1 day. They taste stale afterwards. Another idea is to crumble the scones and toast them in a pan. These crumbles are PERFECT to top fruit crumbles or parfaits (like this pumpkin pie chia pudding parfait!).
