Preheat the oven to 300°
Mix the maple syrup with the almond butter and vanilla and heat in a saucepan on the stove on low heat until well combined.
Combine all the ingredients except the chocolate chunks. Bake on an extra-large (half-sheet) parchment lined baking sheets for 25 minutes, stirring a couple times to keep edges from burning.
Right after removing the granola from the oven, add the chocolate chunks.
Cool and store in an airtight ½ gallon jar. I keep mine in the pantry, however some people like to keep their granola in the refrigerator or freezer.
