Preheat the oven to 300 degrees.
With your hands, rub in the peanut butter.
Spread the mix evenly on a baking sheet lined with parchment paper.
Bake for up to 20 minutes, turning and tossing with a spoon every 3-5 minutes. Be careful not to let it burn.
When golden and dark to your liking, remove and cool immediately to get it crispy. I throw mine on a plate and put it in the fridge.
Divide into baggies. This mix will keep in your cupboard for a couple of weeks.
