The guest list and wedding dress designer for Prince Harry and Meghan Markle’s fast-approaching wedding remain a secret, but now we know who will design their wedding cake.

The couple has selected pastry chef Claire Ptak, owner of Violet Bakery in Hackney, East London, Kensington Palace announced today.

Harry, 33, and Markle, 36, have asked Ptak to create a cake with the flavors of spring for their May 19 wedding. The lemon elderflower cake will feature buttercream icing and fresh flowers as decorations, according to Kensington Palace.

Harry and Markle are “very much looking forward to sharing this cake” with their wedding guests, the palace said.

The choice of a lemon elderflower cake is a departure from the royal tradition of serving British fruit cake on the wedding day.

Harry’s brother, Prince William, and his wife, Princess Kate, had two cakes on their wedding day in 2011, a traditional eight-tier fruit cake created by chef Fiona Cairns and a chocolate biscuit cake from a Buckingham Palace recipe that was a favorite of William’s as a child and also enjoyed by Queen Elizabeth.

Markle and Harry will have two receptions on their wedding day. The first will be a reception at St. George’s…
