Pre heat your oven to 160c. Place all the dry ingredients into a bowl. add in the wet ingredients and give it all a good mix. It's best to mix it by hand, it'll get messy but it's worth it. Lay the mixture onto a baking paper lined tray (or 2 if you prefer) and bake. Check on the muesli every 5-10 minutes or so and give it a good toss to avoid any bits getting burnt. The muesli should be done after 30-40 minutes or until crispy. If you have the time, leave the muesli in the oven after turning it off, this will give the muesli more time to crisp up and dry.
