My main problem with making muesli bars is that the mixture doesn't bind and the slices just fall apart. So then I just chuck the crumbly bits back into the granola jar and have 'twice baked' crunchy granola. This recipe was a bit crumbly so I'd suggest using less nut mix or adding a bit more oil or sweetener. It comes from Sarah Wilson's I Quit Sugar.

2 c mixed nuts and seeds, roughly chopped
2 c rolled oats
2 c coconut flakes (I used thread)
6 Tbs coconut oil or butter
3/4 c rice syrup
1c pumpkin puree
1 tsp each of cinnamon, ground ginger, all spice
1/2 tsp ground cloves
5 Tbs chia seeds

Preheat oven to 160C. Line 2 x 20cm sq tins.
In a large bowl mix the nuts, oats and coconut. In a saucepan melt the coconut oil, rice syrup, coconut oil and spices. Add chia seeds and bring to boil.
Take off heat and pour into bowl, mix thoroughly with nut and oat mixture. Really thoroughly.
Press mixture evenly into tins and bake for 30-40 mins until golden.
Remove from oven and allow to cool before slicing into bars.
