Why Unicorn Birthday Cakes Are Still So Popular
Unicorn cakes hit a sweet spot most themes don’t.
They’re:
- fantasy-based (but not tied to a single character)
- colorful (but customizable)

That means you can:

- reuse decor pieces across parties
A unicorn birthday cake isn’t one look.
It’s a category.
