Preheat oven to 300°F. Line one large, rimmed sheet pan (half-sheet) with parchment or a Silpat. In medium saucepan melt the butter and sweeteners. Once melted, stir in the vanilla and salt.
Combine oats, coconut, nuts and seeds, and cocoa powder in a large bowl. Drizzle with syrup and mix to combine. Transfer to prepared sheet pan and spread out into an even layer. Bake for 60 minutes, stirring 2 or 3 times during baking. The granola will crisp up as it cools. Allow to cool and store airtight.
