In a large bowl, stir together the dry ingredients (minus chocolate chips).
Melt the liquid ingredients together and pour over dry. Stir until evenly coated.
Transfer mixture to a baking sheet and bake for 35 - 45 minutes, stirring every 10 - 15 so granola doesn't burn.
When golden brown, remove from oven and let cool completely. Stir in chocolate chips and store in an airtight container for 2 - 3 weeks.
Notes
If you can't find vanilla powder (I have a link there and I definitely suggest you pick some up - it's so worth it!), you can substitute 2 teaspoon vanilla extract.
