Every 6 yr old wants to celebrate their birthday in as many ways as possible and my granddaughter is no different. Over and above her birthday party, cupcakes were a must to bring to school. Being an avid baker’s assistant, Kate insisted on us creating rainbow cupcakes. Another easier than it seems project!
Using a basic white cake batter is probably the best to keep the colours bright and accurate. Once the batter is mixed and ready, simply divide it into separate bowls; one for each colour. Kate wanted bright colours so we used yellow, pink, blue and green.
A spoon can be used to fill the cupcakes but I find it easier to use small ziploc sandwich bags and just snip the corner so that it works like a piping bag.
It is just a matter then of putting a small amount of each colour of batter in each cupcake liner. Alternating colours and using only small amounts of each will give the rainbow look once baked. Fill fairly quickly so the batter does not have time to spread and level out — unless you want layers more than random colours.
Once baked, the cupcakes end up with fun and brightly coloured inside which the kids all love.
You can also do the same with the frosting to create a rainbow coloured topping to the cupcakes or use one colour and add multi-coloured sprinkles on top.
