Start practicing your British accent! This weekend, The Cup — a gourmet cupcake shop with locations in the Central West End (28 Maryland Plaza) and Edwardsville, Illinois (1057 Century Dr.) — is giving away a free cupcake to anyone who orders five cupcakes while doing their poshest impression of the Queen herself.

“We thought this would be an absolutely brilliant way to celebrate the Royal Wedding,” The Cup owner Ericka Frank says. “After all, no wedding is complete without the perfect cake — or in this case, a classic vanilla cupcake!”

The Royal Wedding Cupcake features a French vanilla cupcake topped with vanilla buttercream, white pearl jimmies and a British flag — perfect for anyone who plans to sparkle like Markle this weekend.

The Royal Wedding Cupcake will be available Friday, May 18 and Saturday, May 19 at both locations of The Cup. This offer is good for one free cupcake per customer and cannot be combined with any other offer.

The Cup Central West End, located at 28 Maryland Plaza Rear, St. Louis, MO 63108, 314-367-6111. The Cup Edwardsville, located at 1057 Century Dr., Edwardsville, IL 62025, 618-656-2287.
