Prepare a batch of buttercream using the recipe of your choice.
Divide the buttercream into 5 bowls.
Add gel food colouring in a different colour to each bowl. Begin with just a little food colouring and add more as you go if you want the shade to be stronger.
Cut off the tip of a piping bag and insert a piping tip.
Use different tips for the different colours and pipe from the middle outward.
Add birthday candles and sing to the birthday child!
Bake a summery birthday cake with impressive piping! With buttercream in lots of colours and piping tips in different shapes and sizes, you can make a brilliantly colourful summer cake. Pipe lots of flowers on top of the cake and down the sides, preferably at different levels and across surfaces that you've already frosted. The result will look almost like shells or coral. Remember to hold the tip close to the cake while piping, so that you can guide where the buttercream goes. Pipe by pressing one hand over the filled piping bag and guiding with the other hand lower down on the bag.
