Storage: Store any leftovers in an airtight container in the fridge for up to 2 days. The apples will soften slightly but still taste great. For the best texture, add the granola right before serving so it stays crunchy.
Nut butter swap: Any nut butter works here! Almond or cashew butter are both delicious alternatives to peanut butter. You can also use powdered peanut butter (PB2) if you prefer a lighter option.
Make ahead: To prep this in advance, mix everything except the granola, cover and refrigerate. Add granola just before serving for the perfect crunch.
