I have made a version of this treat in every restaurant I have worked in since the beginning of my food journey. I have seen many recipes including seeds and coconut etc, but I like to keep it simple. Like everything it is best to make with as few ingredients as possible.
Make the Date Jam first. Simply put 300g of pitted Dates in a pot and cover with Water (about half an inch over the top of the dates). Bring to the boil and simmer for about 20mins until soft. Mix together with a wooden spoon until you get a smooth jam. It may be necessary to add more water. Melt 250 g of Margarine and rub it in to 500g of Oats. Add a drop of milk and test how the mix holds together by squeezing some in you hand. You will have to adjust the amount of soya milk.
Spread half of the Oat mix onto a shallow baking tray. Put in a fairly hot oven until it gets some colour (about 10 mins)
Spread the Date Jam on the Oat base and the sprinkle the rest of he Oats on top. With wet hands, pat it down until smooth. Bake until a nice golden colour.a
