This season’s hottest collaboration is Dolly Parton x Duncan Hines, apparently.

America’s sweetheart hopes to make bakers’ lives a little bit richer with her new line of cake and frosting mixes inspired by Southern recipes.

“I have always loved to cook and, growing up in the South, I especially love that authentic Mom and Pop kind of cooking,” Parton said in a release. “I am excited to launch my own line of cake mixes and frostings with Duncan Hines, bringing that sweet, Southern-style baking experience I enjoy to others.”
