Preheat oven to 300F (150C) and line a rimmed baking sheet with parchment paper. Set aside.

In a large mixing bowl, stir together oats, nuts, cocoa powder, coconut, and any of the optional add-ins listed at the bottom of the recipe.

In a separate, medium-sized bowl, whisk together (melted) coconut oil, honey (or maple syrup), sugar, vanilla extract, and salt.

Pour the wet ingredients over the oat mixture and use a spatula to stir until all of the dry ingredients are coated with the wet.

Spread into an even layer onto prepared baking sheet and transfer to center rack of 300F (150C) preheated oven and bake for 40 minutes or until granola appears dry.

Immediately after removing from the oven, sprinkle chocolate chips and flaky sea salt over the surface of the granola (see note). Allow granola to cool completely, then use your hands or a wooden spoon to break the granola into clumps (if you break up the granola before it has cooled completely you will not have a clumpy granola).
