Dolly Parton has found a delightful way to promote her new book, Fox Business reports

The country music legend joins forces with Jeni’s Splendid Ice Creams to bring back a custom made flavor for Parton: strawberry pretzel pie, which the pastry chef describes as “a throwback to the triple decker pie of our youngsters’ potlucks.”

The limited release of the ice is linked to the release of Run, rose, run, a novel Parton co-wrote with James Patterson, and Parton’s album accompanying the book. Readers, listeners and connoisseurs of frozen desserts can get a digital version of the album with a bonus track when they try Parton’s ice cream, Jeni’s announced in a tweet.

Run, rose, run, published March 7 by Little, Brown, follows an aspiring country singer on the run from her past. A Kirkus reviewer said the “fairy tale characters and details of the country music scene are so fun you won’t mind the crazy plot.” As for the ice cream, Jeni’s says it has “layers of salty pretzel streusel, subtly sweet and effortlessly tangy cream cheese ice cream, and lipstick red strawberry sauce.”

The ice cream will benefit Parton’s Imagination Library, a program that sends free books to children from birth to age 5.

The frozen treat is limited to two pints per customer (but you can still buy all the brambleberry crunchy and gooey butter cake you want).
