There are a few simple tricks you can use to make sure your Golden Graham treats stay soft.  • First, make sure to start with fresh marshmallows. Don’t try to use that bag that’s been in the pantry for 6 months…. It just won’t work the same.  • Second, don’t press too firmly in the pan - press just gently enough to flatten them out. If they are too tightly compressed, they will get hard.   • Third, make sure to store them in an air-tight container. Exposure to air makes them get harder and stale much quicker.  • Last, don’t be afraid to reheat them slightly in the microwave before eating. I like to microwave mine for 5-7 seconds and they are DIVINE.
