Instructions

Preheat the oven to 275°F.
In a medium bowl, crush the cornflakes with your hands until they are about one-quarter their original size. Add the milk powder, sugar, and salt and mix to combine. Set aside.
Melt the butter in 30 second increments in the microwave and then combine with the dry ingredients until everything is coated.
Pour the cornflake mixture onto a sheet pan lined with parchment paper and bake for 20-25 minutes until toasty.
Let the cornflake crunch cool completely before using.
