Tip the oats, coconut flakes and mixed seeds into a large frying pan/skillet. Place this over a medium heat on the stove and dry toast, stirring often, until it starts to smell toasty and nutty.

Turn the heat down to low, make a hole in the centre of the oats and place the butter (or olive oil) and maple syrup in the hole. Let the butter melt (if using) then stir everything together so all of the oats are coated with the fat and syrup.

Toast over a low heat, stirring constantly for another 2 minutes to help it crisp up - the texture will still be quite soft but as it cools it will harden.

Tip the granola out onto a large plate or tray and set aside to cool and get crispy.

NOTE: this makes excess granola so once cooled, store in an airtight jar.
