300 g (10 oz) Margarine 
275 g (9 oz) Sugar
2 tsp Vanilla sugar
tsp rum essence
1 pinch Salt
5 Eggs
375 g (13 oz) Plain flour
4 tsp Baking powder
About 3 tbsp juice or wine

Use the whisk on a hand mixer or a food processor to cream the margarine, then gradually add the sugar, vanilla sugar, rum essence and a pinch of salt. Continue to beat until the mixture is light and fluffy. Add the eggs as you beat (one every 30 seconds or so). Mix and sift the flour and baking powder. Gradually add the wine or juice to the creamed fat, beating continuously at medium speed. Only use as much wine as necessary to give the mixture a slow dropping consistency.

Transfer two-thirds of the mixture into a greased 22-24cm (8-9 inch) cake tin

4 tsp cocoa powder
4 tsp sugar
2-3 tbsp wine
Sift together the cocoa powder and sugar and add to the remaining third of the mixture, together with the wine. Beat until the mixture returns to a slow dropping consistency. Spread the chocolate-coloured mixture over the light mixture and then lightly swirl the two together with a fork to create a marbling effect
