OK - here is another family favourite. I remember making these with my Grandma on the farm when I was so small even standing on a kitchen chair I was barely tall enough to mix it up in the bowl.
2 cups flour
2 tbsp white sugar
4tsp baking powder
3 tbsp vegetable oil
125ml milk (approx - depends on room humidity)
Butter, light brown sugar (light muscavado), cinnamon
Mix the sugar, oil and egg together in a bowl. Add the baking powder and mix. Then add in half the the flour and mix well. Finally alternating between the remaining flower and milk, add it in until you get a dough. You will need to use your hands to mix it.
Roll out on a floured surface so it forms a rectangle, about 1cm thick.
Spread butter over the dough surface, sprinkle on the brown sugar and cinnamon. Then, starting along the long edge, roll the dough up until you have a log. Cut the log into finger width cookies, and place flat on a cookies sheet. Bake at 350 for 15 minutes.
