To make this amazing cake first you have to make cake batter for one cake and divide it in small bowls. Colour each bowl with a separate food colour. Fill piping bags with coloured batters and then drizzle the batters to form a rainbow of colours as shown.
Then make a plain cake batter and pour it in a cake tin almost till one third. Join the numbers together and make a row of them in the centre of the slightly filled cake tin. Cover the letters gently with cake batter and bake the cake.
Next step, cover the cake with icing
Now make some tie-dye fondant by twisting and rolling colored fondant logs.
Then cover the cake and you are all done!! look at it, just look at it! its a thing of beauty!
