Preheat your oven to 350 (if you like it less "crispy," set to 335 or 340)
Line a baking sheet with parchment paper.
Combine all ingredients (except raisins) into a large bowl and stir until combined well.
Spread the mixture on a baking sheet in an even layer, pressing down gently.
Bake for 20-30 minutes, or until done.
Let cool completely, add raisins, and break into chunks. Add as a topping to oatmeal, yogurt, or just for snacking!
