Premium Rainbow Cake

This modern, sponge-free showstopper is designed for the ultimate cream enthusiast. It features precision-stacked layers of firm, silk-smooth buttercream in a vibrant rainbow gradient, separated by thin ribbons of white chocolate ganache for structure and richness. Encased in a minimalist white frosting, the cake hides a high-impact color surprise that is revealed only when sliced, offering a dense, melt-in-your-mouth texture with a clean vanilla bean finish.
