Lilibet Had a Pink Cake Covered in Peonies for Her First Birthday Party

Baker Claire Ptak also made the wedding cake for Prince Harry and Duchess Meghan's 2018 nuptials.

Earlier this month, family and close friends of the Duke and Duchess of Sussex

celebrated the first birthday of baby Lilibet "Lili" Diana Mountbatten-Windsor

with an intimate backyard picnic hosted at Frogmore Cottage, where guests were treated to face painting and cake.

Now, baker Claire Ptak has shared a first look at one-year-old's special custom party cake.

Ptak, who made Prince Harry and Duchess Meghan's cake for their 2018 wedding,

posted a behind-the-scenes glimpse into the making of Lilibet's treat.

The two-tiered cake was covered in pale pink frosting and multiple pink and white peonies.

It also included an orange flag cake topper that spelled out her name.
