01 - Preheat the oven to 325°F and line a baking sheet with parchment paper.
02 - In a large bowl, mix the oats, almonds, cranberries, coconut (if using), cinnamon, and sea salt until evenly distributed.
03 - Gently warm the honey (or maple syrup) and coconut oil in a small saucepan over low heat until melted and combined. Remove from heat and stir in the vanilla extract.
04 - Pour the warmed wet ingredients over the dry mixture and stir thoroughly until all components are evenly coated.
05 - Transfer the mixture onto the prepared baking sheet, pressing firmly with a spatula to create a compact, even layer to encourage cluster formation.
06 - Bake for 20 to 25 minutes, rotating the pan halfway through, until the clusters are golden brown and aromatic.
07 - Allow the clusters to cool completely on the baking sheet without stirring to maintain their shape, then break into pieces.
08 - Store in an airtight container for up to two weeks to preserve freshness.
