Insights

A promotional seasonal Birthday set from 2025, Birthday Cake (40780) draws steady gift-season interest but its mass distribution, generic minifigure, and absence of exclusive elements have kept long-term upside modest, and frequent theme refreshes leave remake risk that constrains post-retirement scarcity.

Set Facts

The decorative birthday cake features chocolate icing, colorful sprinkles, and chocolate and orange pieces on the top.
When the cake is opened, a play scene is revealed featuring a minifigure with two different hair pieces, plus a table with a cake and present.

“The LEGO Birthday Cake set features a tiered, chocolate-iced exterior with colorful decorations and opens to reveal a small party scene with a minifigure, table, and gifts. The build includes clever design touches like asymmetry for a more realistic cake look and two hair options for the included minifigure.”
