Halloween Just Got a Marshmallow Makeover with Butterfinger’s Latest Innovation

Building on the tremendous success of Salted Caramel, Butterfinger has officially launched its latest innovation, Marshmallow Butterfinger – the perfect blend of Butterfinger’s signature crispety, crunchety texture and peanut-buttery center, wrapped in a smooth marshmallow-flavored coating for a fun and unexpected twist on the fan favorite.

Available for a limited time this Halloween season, Marshmallow Butterfinger taps into the beloved flavor memories of classic fluffernutter sandwiches and transforms them into an exciting new candy experience. The launch showcases Butterfinger’s ongoing commitment to creative flavor development, with Ferrero’s Consumer Testing revealing that 83 percent of consumers found marshmallow to be a unique flavor in the candy bar category. As Millennial and Gen Z audiences continue seeking both comfort and novelty, Marshmallow Butterfinger arrives at the perfect time to spark nostalgia this Halloween.

“Following the extremely positive consumer response to Salted Caramel Butterfinger, we’re continuing our flavor innovation journey by introducing a new twist on a classic flavor—marshmallow,” said Kalyn Flournoy, Senior Brand Manager for Butterfinger. “Marshmallow brings back childhood memories of baking homemade treats for trick-or-treaters and costume parties. That familiar flavor pairs beautifully with our peanut buttery center, creating a nostalgic combination that transports you back to simpler times just in time for Halloween.”

Butterfinger is also returning for its second-year partnership with the Queen of Halloween, Heidi Klum, for her legendary 24th annual Halloween party, the perfect backdrop to unveil the brand’s hauntingly delicious bar. Guests will have the chance to experience the new Marshmallow Butterfinger along with classic Butterfinger treats including the Butterfinger-tini, a cocktail inspired by the candy bar featuring notes of butterscotch, chocolate and peanut butter whisky.

“Halloween is my favorite time of the year and what better way to celebrate than by teaming up with an iconic candy bar brand who loves it just as much as I do,” said Heidi Klum. “Their new Marshmallow Butterfinger is so yummy, and I can’t wait for my guests and you at home to enjoy the delicious candy bar this Halloween.”

Butterfinger lovers can find Marshmallow Butterfinger at major retailers nationwide from September to November.
