Preheat oven to 300 degrees. Line a baking sheet with parchment paper. Set aside.
Combine all ingredients except for the chocolate chips in a large bowl. Toss to combine. Evenly spread the mixture on the parchment-lined baking sheet.
Bake the granola, stirring every 10 minutes, until golden brown, about 40 minutes. Remove from the oven and transfer the granola to a large bowl. Immediately add in the chopped chocolate chips and toss to combine. Spread the mixture back onto the parchment-lined baking sheet and allow to cool completely before transferring to an air-tight container.
