Recently, the actress ordered a batch of red velvet and grasshopper flavored Isabelle's Curly Cakes cupcakes delivered to the Canadian set of her History Channel miniseries, The Kennedys, where she is playing Jacqueline Kennedy.
And we bet Jackie O. would want in on these goods.
The cupcakes are sold exclusively at Todd English's Food Hall at the Plaza Hotel in N.Y.C. The chef behind the fluffy batter and frosted treat? English's 16-year-old daughter, Izzy, who was thrilled about her new client.
"Izzy was so excited when I told her about Katie’s special order," English tells PEOPLE. "She asked if Tom and Suri were going to try them too. She's a big fan of them, so she thought it was very cool ... The red velvet and the grasshopper are definitely the most popular Curly Cakes at The Food Hall."
So what makes Curly Cakes so special?
"A little trick we do is the slight touch of red wine vinegar and the small amount of cocoa powder in the cake mixture, which gives them that velvety smooth texture," English says of the red velvets. "And we use cream cheese frosting, so it's a tad tangy and not too sweet."
And this sweet behavior isn't exactly new for Holmes, who's known for delivering treats – especially cupcakes – to the crews on her movies. In 2007, she delivered pizza and cupcakes to the Louisiana set of Mad Money. One reason for the special delivery? "She loves cupcakes, okay?" her hubby, Tom Cruise, told PEOPLE. "I mean, the girl loves cupcakes."
And she's not the only star who does: Everyone from Paris Hilton to Selena Gomez can't get enough of these baked goodies.
