Crucial Checkpoints for Monster Krispies

- Look for a golden hue on the edges of the cooled treats—indicates perfect setting.
- The treats should hold together when pressed but still be chewy and slightly sticky.
Avoid These Krispie Crumbles: Mistakes & Fixes
- Too high heat melts marshmallows unevenly.? Use low heat to prevent marshmallows from burning or becoming stringy.
- Over-pressing makes treats dense and hard.? Don’t press too hard when packing the mixture; keep it loose for easier cutting.
- Mixture sticking to tools.? Add a little butter or oil to your spatula if sticking becomes an issue.
- Chilling too quickly causes condensation.? Cool the treats at room temperature, not in the fridge, to avoid sweating.
