Called Tararua biscuits across the Tasman.
I'm headed up the hills in a few days for a weeks ramble and I just baked up a batch of bush biscuits.
There is some discussion locally on whether you have better food value just picking up rocks by the side of the track and if Dwarf battle bread might be a better option for the safety of your teeth.
Absolutely no measurements were involved in this crime against stomachs, but a mix of Wholemeal flour, quick rolled oats, self raising flour, almond meal, dark brown sugar [ like dry mollasses] sunflower oil and a little water. An hour in the fan forced oven at 135C and then cool in place.
Cut into 18 large rectangles before baking. That's a kilo of biscuits at a ration of 2 or 3 per day.
I'll let people know how they ate if I survive to tell.

Definitely not definitive recipes as every batch I have ever made is different, some better some not so much.
The best I have ever made was with buckwheat flour
