This week my elder child turns twelve years old. She has requested for a rainbow cake for her birthday. I was not very keen to bake this cake initially as it is quite tedious and time consuming.
You see, each layer of the coloured batter has to be baked seperately. My oven has the capacity for baking two six inches layers at one go but I find the baking uneven thus prefers to bake each layer one at a time. Another reason which holds me back is this cake uses many food colourings. Eventually I relented as I thought it would be very meaningful as my girl will be taking her PSLE examinations soon and I would like her to do well and pass with flying colours! This cake is so colourful! It won't hurt much since it is not consumed that often. Another intention is I hope to motivate her to work hard for her coming exams and be a good role model for her as mummy takes up this tedious task.
The day before her birthday, she was going back to school during the one week September school holiday for her supplementary lesson. I thought it would be nice for her to celebrate her birthday in advance with her classmates. I used the same rainbow cake recipe to make the rainbow cupcakes for her to bring to school and all her friends love this colourful rainbow cuppies and commented that it is too pretty to be eaten!
