Preheat your oven to 350°F (175°C) and line a baking sheet with parchment paper.
In a large mixing bowl, combine the rolled oats, chopped almonds, cocoa powder, and salt.
In a small saucepan over low heat, melt the peanut butter and honey (or maple syrup) together until smooth, stirring continuously. Remove from heat, and stir in the vanilla extract.
Pour the warm peanut butter mixture over the oat mixture and mix thoroughly until all the oats are coated.
Spread the mixture evenly onto the prepared baking sheet in a thin layer.
Bake in the preheated oven for 20-25 minutes, stirring halfway through, until the granola is crisp and golden brown.
Remove from the oven and allow to cool completely on the baking sheet. Once cooled, mix in the dark chocolate chips.
Store the granola in an airtight container for up to two weeks.
