I have a bread maker that has a bake function on it - so i cook this fruit loaf for approx 1 hour or until cooked (ie not soft in the middle) so could work for a camp oven - this is the 1/2 size receipe so just double for camp oven
Bread maker purchased from Aldi
soak together for 10mins
1 cup rolled oats
1/2 cup of sugar
1 cup of milk - I just use dried milk powder (3 tbsp to 1 cup of water)
1 cup of dried fruit / nuts - what ever you have in the pantry
add
1 cup plain flour
1 tsp baking powder
keeps well - just slice it
sometimes I add grated lemon rind , handful of coconut to change the flavour
