  • The day old croissant rule is real fresh ones turn into mush when you try to stuff them
  • Do not overfill or the cheese will spill out and burn on your baking sheet
  • Letting them rest for two minutes after baking prevents that tragic first bite burnt tongue situation

  • Freeze extra stuffed croissants before baking and pop them straight in the oven for 20 minutes
  • Room temperature filling spreads much easier than cold filling
