Preheat oven to 325 degrees F. Line an 8-inch square metal pan with foil and spray foil with cooking spray.
Chop the peanuts and the white chips.
Melt the butter in a large saucepan set over medium heat. Stir in the salt, corn syrup, brown sugar, and peanut butter. Stir just until bubbly and remove from heat. Stir in the granola and oats, followed by the chopped peanut mixture.
Pour into the prepared pan and bake at 325 for 10 minutes. Remove from oven (bars will appear bubbly and moist) and set on a rack to cool. While the bars are still hot, sprinkle chocolate chips over the top. Let cool for about an hour at room temperature. Lift foil from pan, score into bars (I made 16, but you can do 12 or 9) without separating, then chill until firm. Separate.
