Well low and behold, that day finally arrived and I discovered that this is indeed a very quick chocolate cake to make with store cupboard ingredients.
Abbie calls it the 'wacky chocolate cake' and it tastes great. Abbie's ingredients are in Australian cup measurements so I have also given UK measurements where necessary.
1, 1/2 cup (200g) of Plain flour
3/4 cup (150g) of sugar
3 tablespoons of coca
1 teaspoon of bicarbonate of soda
1 teaspoon of vanilla
1 tablespoon of vinegar
6 tablespoons of cooking oil
then 1 cup (250ml) of warm water to the mixture, stir with a fork till smooth.
Bake for 25-30 minutes at 180C.
Thanks Abbie for letting me blog this and everyone else do enjoy!
