Peel and roughly grate the apples. Place in a pot, add the sugar, cinnamon and apple juice and let stand for about 20-30 minutes or until you notice that the apples have released more juices.

Stir in the pudding powder (OR corn starch and vanilla extract), mix well, place on the hob and bring to a boil stirring often. Let bubble a couple of times until the mixture thickens like a pudding.

Line a baking tray or a rectangular dish (20x30 cm/ 8x11 inches) with plastic wrap. Arrange one layer of biscuits in the dish. Pour half of the apple mixture over the cookies and level. Cover with another layer of biscuits. Pour the rest of the apples on top, level and add the third layer of biscuits.

Cover with plastic wrap, let cool slightly, then place in the fridge for about 3 hours or until the apple mixture is cold and set.

When ready to serve remove the plastic wrap from the top of the cake. Place a suitable serving dish on top of the cake, grab both dishes and turn them simultaneously, so that the cake falls onto the serving platter. Remove the second plastic wrap.

Sprinkle the cake with icing sugar and cut into squares the size of the biscuits.
