In a large mixing bowl, combine the oats, maple syrup, coconut oil, and spices. Toss to coat well.
Spread the granola in an even layer on the prepared baking sheet.
Bake the granola until it is golden brown, about 12 to 20 minutes. Half way through cooking, mix the granola to ensure even cooking.
Remove the granola and let it cool.
In a large mixing bowl, combine the oat mixture, coconut, berries, and plums.
