Notes

Pro Tip: Avoid stirring too vigorously during the halfway point to get clumpy granola. Instead gently flip with a spatula. Once you remove it from the oven, allow it to cool completely on the cookie sheet without touching it. This allows the granola to set into crunchy clusters.
Storage Tips: Granola can be stored in an airtight container at room temperature for up to 3 weeks or in the freezer for up to 3 months.
