Ombre Princess Birthday Cake Pink ombre butter cream frosting with pink and silver cachous and dress up tiara for decoration (I beaded the dangle in the tiara using a light and dark pink crystral bead to reflect the light and dark shading in the icing). Hiding underneath is a 5 layer purple ombre cake made with my never fail butter cake, coloured with Wilton gel colouring. Raspberry jam and more of the frosting was used to sandwich the layers together.
