Prince Harry and Markle announced their engagement last November and will marry in St. George's Chapel in Windsor Castle.
Prince Harry and Meghan Markle revealed who will make the cake for their May 19 wedding.
The honor has fallen to pastry chef Claire Ptak, who was raised in California and now owns London-based bakery Violet Cakes, Kensington Palace announced Tuesday.
According to the palace, the couple asked Ptak to make a "lemon elderflower cake that will incorporate the bright flavours of spring" rather than the more traditional fruitcake. It will also feature buttercream and fresh flowers as decoration.
The bride-to-be is already acquainted with Claire Ptak, having interviewed her for her former lifestyle website The Tig.
"Prince Harry and Ms. Markle are looking forward to sharing the cake with guests at their wedding at Windsor Castle on May 19th," wrote Kensington Palace on Twitter.
"I can't tell you how delighted I am to be chosen to make Prince Harry and Ms. Markle's wedding cake," Ptak said in a statement released by Kensington Palace. "Knowing that they really share the same values as I do about food provenance, sustainability, seasonality and most importantly flavour, makes this the most exciting event to be a part of."
Prince Harry and Markle are not the first royal couple to deviate from more traditional cake choices. At his wedding to Kate Middleton in 2011, Prince William requested a "groom's cake" made of cookies and chocolate.
