1 day in advance, make drop flowers using royal icing. Cover cake board with waxed paper. Use tip 2D and pipe approximately 30 drop flowers with tip 3 dot centers in white royal icing. Make extras to allow for breakage and let dry.
Bake and cool 2-layer and 1-layer cake tiers to make 5 in. high cake. Ice in light pink buttercream icing. Attach drop flowers to cake with dots of icing. Connect flowers with strings of tip 3 dots in white buttercream icing. Add tip 18 shell bottom border in white buttercream.
Drop flowers are a great way to add flowers quickly. Pipe drop flowers in buttercream directly on your cake, or pipe in royal in advance and place your flowers anywhere. Flowers will be sharper in definition when piped in royal.
