These are scrumptious and quick to make.
4oz /100g butter
3oz /75g sugar (vanilla sugar is good)
4oz/100g plain flour
1oz/25g cocoa powder
Vanilla essence (if not using vanilla sugar)
1oz/25g medium oatmeal (if you don't have oatmeal, you can use rolled oats chopped finely in a whizzy machine)
Cream butter and sugar, add flour, cocoa, oatmeal and vanilla and mix well with wooden spoon until you get a smooth, stiff dough.
Roll it out on a floured surface to about 1/4 inch thick, and cut out small/medium size shapes (approx 1 to 2 inch diameter). Put these on a greased baking sheet and bake at 180ºC / mark 4, for 10 mins. When out of the oven leave for a minute or two on the baking sheet and once they've hardened up a bit transfer to cooling rack.
