Put ingredients 1 to 6 in large bowl and beat with electric beater until all ingredients have blended together. Add a dash more of soy milk if needed. Bake in moderate oven (about 180-200 degrees celsius) for about 45 minutes until cooked. Test with knife to determine if properly cooked.
Allow to cool then top with cocoa icing prepared as follows: place icing vegan sugar and cocoa in bowl and add a dash of soy milk. Then stir. Keep adding dashes of soy milk until icing is very thick (do not let the icing become runny). Hint - use a hot knife to spread icing.
