Begin combining and beating the ingredients in the order listed. Pour the prepared mixture into a form that you've buttered and floured ahead of time.
Bake the layer in a moderate oven until your toothpick comes out dry when you poke it.
Remove from the form. Once it cools completely, cut it into 2-3 separate layers. Stick them together with marmalade and cream.
Decorate the entire cake with cream and sprinkle it all over with grated chocolate and nuts.
