Preheat your oven to 350°F (175°C).
In a large mixing bowl, combine the peanut butter and honey. Mix until smooth.
In another bowl, mix together the oats, chopped peanuts, raisins, dried cranberries, oat bran, and salt.
Pour the dry mixture into the bowl with the wet ingredients and mix thoroughly.
Line your baking sheet with parchment paper, pour the granola mixture onto it, and spread it out evenly.
Bake for about 25-30 minutes, stirring halfway through, until golden brown.
Once baked, let the granola cool completely on the baking sheet before breaking into clusters.
