Over the Rainbow Pastel Cake

A slice of pure happiness and blue skies. This cheerful, dreamy cake features a smooth pastel-blue buttercream finish reminiscent of a clear spring morning. The sides are decorated with a hand-piped repeating pattern of charming, textured pastel rainbows emerging from fluffy white buttercream clouds, interspersed with delicate yellow and white sugar stars. A classic, pillowy cloud border frames the top to complete this picture-perfect design.
