What’s a fluffy and delicious cake with a buttery surprise inside? Betty Crocker’s answer: Chocolate Buttermallow Cake.

We’ve made it to 100 episodes of Unboxing Betty! Let’s celebrate with a classic cake recipe from the box — this cake uses Devil’s Food Cake Mix, spread with a layer of butterscotch and topped with marshmallow frosting, swirled with chocolate.

Plus, we whip up the history of Marshmallow Fluff.

Happy Homemaking!
