What kind of cup doesn't hold water?

The delightful treat that famously cannot hold water is, of course, a cupcake. This playful riddle hinges on the double meaning of "cup." While a traditional cup is a vessel designed to contain liquids, a cupcake is a miniature cake, a delicious baked good intended for eating, not for holding beverages. The "cup" in its name refers to its size and original baking method, not its function as a container.

The history of this beloved dessert offers an interesting look into early American baking. The earliest known reference to a cake baked in individual portions dates back to 1796, when Amelia Simmons included a recipe for "a light cake to bake in small cups" in her cookbook, "American Cookery". The actual term "cupcake" first appeared in Eliza Leslie's "Seventy-five Receipts for Pastry, Cakes, and Sweetmeats" in 1828. There are two prevailing theories for the name's origin: either the cakes were literally baked in individual pottery cups or ramekins before modern muffin tins were common, or the ingredients themselves were measured by the cup, leading to simple "number cakes" like a "1234 cake".

Regardless of the exact naming origin, these small, individually portioned cakes gained popularity for their convenience and quicker baking time compared to larger cakes. The advent of multi-cupcake tins further streamlined their production, and by the early 20th century, companies like Hostess began mass-producing them. Today, cupcakes remain a cherished treat, celebrated for their versatility in flavors and decorations, a far cry from their simple beginnings as cakes baked in cups.
