So popular, in fact, that it not only crashed the website where it was being sold, it's also now being flogged on eBay for a whopping $1,000 (£729) a tub.
The country icon teamed up with Ohio-based company Jeni's Splendid Ice Creams to rustle up her very own flavour, with her Strawberry Pretzel Pie blend described as 'a throwback to the triple-decker pie from the potlucks of our youths'.
The product - which sees cream cheese ice cream layered up with salty pretzel streusel and strawberry sauce - has been created to help Parton's Imagination Library, a programme that offers free books to children up to five years old.
And it seems to have been an instant hit, with Jeni's announcing that demand had crashed its website shortly after the flavour went on sale.
"Did y'all just break our website?" the ice cream company tweeted.
People have since seized the opportunity to sell on the ice cream at a profit, with one listing on eBay offering a tub for $1,000.
The item description claims that 80 percent of the sale would be donate to Dolly Parton's Imagination Library, still leaving the seller with a couple of hundred dollars.
There's an option to either pick-up locally from Pasadena, California, or the ice cream can be 'shipped next day with dry ice'.
If $1,000 seems like too high a price for your budget, you can also make an offer.
Just 10,000 pints of the limited edition ice cream were made, with customers limited to two per purchase.
The product was also being sold IRL in Jeni's stores, but stocks reportedly sold out after people queued up ahead of opening to get their hands on some of the coveted dessert.
Online saw similar hype, with Jeni's saying it had had 50 times the normal amount of traffic to its website during the launch.
The company tweeted at the time to say that the product wasn't actually sold out, the surge in demand had just led to prolonged 'website issues'.
To those of you trying to order Strawberry Pretzel Pie online, we are so sorry. This sucks. The flavor is NOT sold out. Our website issues have lasted longer than expected, but we are working on it and will let you know via email and social media when we're back up and running.
