Preheat oven to 325°F and line a sheet pan with parchment.
In a large bowl, combine oats, almonds, pecans, pumpkin seeds, sugar, and salt.
In a separate bowl, whisk all wet ingredients and chai spices until smooth.
Pour wet mixture over dry and stir to fully coat.
Spread onto the pan and gently press with a spatula to encourage clusters.
Bake 22–28 minutes, stirring once halfway, until lightly golden and fragrant.
Cool completely before breaking into clusters.
Stir in dried fruit if using. Store airtight up to 2 weeks.
