Preheat oven to 350°F / 175°F.
Wash and chop apples. Set aside.
In a food processor or blender, blend coconut oil, apples, maple syrup and vanilla. Set aside.
In a large bowl combine the remaining ingredients, except for the currants. Pour the liquid mixture over the dry ingredients and fold coat.
Spread mixture out in an even layer on a lined baking sheet and press firmly with the back of a spatula to ensure that the mixture is compact. Bake for 15-20 minutes. Remove granola from oven. Using a spatula, flip the granola in large sections. Place back in the oven, continue to bake and flip every 5 minutes or so, making smaller chunks each time, until golden (35-45 minutes total).
Let cool completely and store in an airtight container for up to one month.
