In a small saucepan, combine the syrup ingredients. Place over medium low heat and stir occasionally while mixture melts together and everything becomes incorporated.
While the syrup is heating, mix together the granola ingredients in a large bowl.
When the syrup is melted and the sugar is dissolved, remove from heat and pour over granola. Stir to combine and evenly coat.
Spread granola on two large rimmed baking sheets and place in preheated oven for 45-60 minutes. Stir granola every 10 minutes to ensure the mixture is evenly drying. When done, the granola should feel dry and not clump together easily.
