National Vanilla Cupcake Day Cards

An informal food observance that celebrates the classic vanilla cupcake—its flavor, frosting variations, and role in home baking and bakery menus. It is not a federally recognized or historical holiday; its origins are unclear and it likely arose from promotional food‑calendar listings, bakeries, and social media trends. Celebrations typically involve baking and sharing vanilla cupcakes, posting recipes and photos online, and bakery promotions. Because this observance is unofficial, sources do not agree on a single standardized date.
