Preheat oven to 300°F. Line a large baking sheet with a silpat mat or parchment paper.
Combine the oats and peanuts in a large bowl and set aside. In a smaller bowl, combine the rest of the ingredients, except for the chocolate chips, and mix well. Pour the wet ingredients over the dry ingredients and stir until completely moistened.
Spread the mixture onto the prepared baking sheet in an even layer. Bake for 45 minutes, stirring every 15 minutes for even cooking. Remove from the oven and allow to cool completely, the granola will begin to obtain a crunchy texture as it cools. Store in an airtight container or up to 3 weeks.
