1 tsp vanilla
300g self-raising flour
1 Tbs vinegar
3 Tbs cocoa
Pink food colouring
Place first 7 ingredients into TM bowl. Blend together on speed 5 for 1 minute.
Divide mixture into three portions. Place two portions in small mixing bowls and leave the third in the TM bowl.
Add cocoa to TM bowl. Mix on speed 5 for 10 seconds.
Add a few drops of pink food colouring to one of the extra bowls. Stir through.
Alternately drop spoonfuls of all three mixtures into a greased and lined loaf pan. Continue until all mixture is used up.
Create marbled effect by swirling a skewer back and forth through the mixture a few times. Tap pan on bench to evenly distribute mixture.
Bake in a moderate oven for 1 hour - check to see if it is cooked, it may need an extra 10 minutes or so.
When cold, ice with pink icing.
