Ice the cake and pipe in the stars to make a pastel rainbow. One star each time and my fingers were aching by the time I finished.
Make wavy clouds at the bottom of the rainbow, not a pot of gold. Pipe in the clown and put on it's head.
Viola, my attempt at cake decorating. I baked this lemon poppy seed cake with expired baking powder cos I did not have time to go to the supermarket. I just tasted it, a little too sweet with the icing. I shall use less sugar in the cake next time.
