The mixes, hitting stores later this month, are for buttermilk biscuits, cornbread, and two flavors of brownies inspired by the legendary entertainer's family recipes.
These new baking products build on Parton's cake mixes and frostings brought to market last year by Duncan Hines.
"I knew Duncan Hines and I were bringing something special to the baking aisle when we launched our partnership last year, and I've been thrilled by the response," Parton said in a statement.
A music legend, Parton is a member of not only the Country Music Hall of Fame but also the Rock & Roll Hall of Fame, into which she was inducted in November 2022. She is also a megastar in the world of food.
What baking mixes does Dolly Parton have?
Dolly Parton's Buttermilk Biscuit Mix and her Sweet Cornbread & Muffin Mix will cost $3.29. The Fabulously Fudgy Brownie Mix and Caramel Turtle Brownie Mix will cost $3.49.
These new baking mixes will begin becoming available in grocery stores and mass retailers later this month.
"I'm really excited to launch more baking mixes steeped in my Southern roots, like cornbread and biscuits," Parton said. "I think folks are really going to like them and hope they'll bake up some special memories with family and friends."

What else has Dolly Parton been up to?
She's working on a rock 'n' roll album, and back in November Parton got a $100 million donation to devote to charities of her choice from Amazon founder and billionaire Jeff Bezos' Courage and Civility Award.
Parton is also known for her philanthropic work. In 2020, Parton donated $1 million toward the creation of Moderna's COVID-19 vaccine.
Prior to that, her My People Fund provided about $9 million in 2016 and 2017 to those who lost homes to fire in Pigeon Forge and Gatlinburg, Tennessee. Since she launched the Imagination Library to boost children's literacy in 1995, the initiative has gifted more than 197 million free books to children.
Parton, who turns 77 on Thursday, will be celebrated with two shows at the Ryman Auditorium in Nashville on Saturday. She won't be in attendance on Saturday, but those who visit the Ryman on Thursday can get free birthday cupcakes baked using Duncan Hines Dolly Parton's Favorite Southern-Style Cake Mix (while supplies last).
