It’s no secret Dolly Parton is busy. The country music icon recently celebrated her 78th birthday but instead of time off, she spent the day working, she told Business Insider.

The project? Expanding her line of baking mixes with Duncan Hines. She and the baking company just revealed that the Dolly Parton Baking Collection now includes Chocolate Cake Mix, Yellow Cake Mix, and Cinnamon Crumb Cake Mix, along with the new Blueberry Muffin Mix and Banana Nut Muffin Mix. The lineup also includes a new Buttermilk Pancake mix.

The new products are already rolling out at supermarkets and other retailers early this year, reports Food & Wine.

Dunkin Hines is also launching a limited-edition Dolly Parton “Bake Like a Rockstar” kit, packed with the new products and some special keepsakes. The full kit includes four mixes (Dolly Parton Cinnamon Swirl Crumb Cake and Favorite Chocolate Cake mixes, Blueberry Muffin Mix, and Creamy Chocolate Buttercream Frosting), a magnet featuring an illustration of Dolly, a Dolly Parton-inspired oven mitt, and a set of recipe cards.

The collection is available to purchase exclusively on the Duncan Hines’ Baking With Dolly website. Each kit costs $40 plus shipping and handling.
