Preheat the oven to 160°C. Begin with the dessert apple, peel and core and then cut into dice.  Place in a saucepan with a little water and bring to a simmer, reduce the heat and cover with a lid. Cook for 5-7 minutes then mash with a potato masher.  

Place all the dry ingredients in a large bowl, weigh out the syrup, honey and maple and pour over the oat mixture, finely add the hot apple puree and stir well, adding the puree hot helps to melt the syrups and honey, therefore, coating the oats more evenly.

Place the oat mixture on a large baking tray spreading the oats out as much as possible, (you may need two trays).

Place in the oven and set the timer for 10 minutes, when the time is up, taking a spatula and move the granola around on the tray.  Set the timer for another 10 minutes and do the same. Continue until the oats are golden brown.  Cool and place in an airtight container.
