This Unicorn Rainbow Buttercream Cake is a dreamy pastel celebration cake finished in smooth, soft rainbow bands of buttercream. The tiers are decorated with delicate gold stars and sugar pearls, adding a subtle magical sparkle. On top sits an adorable unicorn topper with a flowing rainbow mane, surrounded by blush-pink buttercream swirls and pastel rosettes. A bright turquoise buttercream border at the base ties the look together, making this cake playful, elegant, and perfect for a unicorn-themed birthday celebration. 🦄✨
