‘We had a baby a couple weeks ago…Here are her feet,’ wrote Mara on the post seen by her 368,000 followers.

In celebration of her girl’s first birthday, Kate ordered a custom cake from local Los Angeles bakery Just What I Kneaded.

The vegan birthday cake included a plethora of pink icing and a frosting depiction of the iconic children’s character Strawberry Shortcake.

Due to the child’s birthday occurring in the midst of the coronavirus pandemic, Mara decided to make Shortcake don an N95 mask.
