If There’s One Fall Festival You Attend in Massachusetts, Make It the What the Fluff? Festival

Fall in Massachusetts is truly something special. Leaf peepers from all over the country visit the area to watch our iconic fall foliage. While most of our autumnal adventures are centered around apple picking and pumpkin carving, there's one special festival in Massachusetts that's keeping the whimsical side of fall alive, and we think it's one of the best fall festivals in Massachusetts. If you've never heard of the What the Fluff? Festival, you're in for a treat! This is certainly one of the most unique festivals in the state.

Peanut butter and jelly go hand-in-hand, but so do peanut butter and marshmallow fluff! If you grew up with peanut butter and fluff (a.k.a. fluffernutter) sandwiches in your lunch box, then you may want to attend what may very well be the best fall festival in Massachusetts. The What the Fluff? Festival celebrates one of the most extraordinary inventions of all time...Marshmallow Fluff!

Gooey, sweet, and sticky, Marshmallow Fluff may very well be one of the greatest inventions of our time. And it was invented right here in the Bay State!

Marshmallow Fluff was invented in Somerville's Union Square in 1917. For a product that's over 100 years old and has brought joy to millions, well, that's something to celebrate!

This year marks the 20th annual What the Fluff? Festival. It will be held on September 20, 2025, just a few days before fall. Should the weather decide to take a turn, the festival will reschedule on September 21, 2025, from 2 p.m. until 6 p.m.

Celebrating 20 years of sticky, sweet Sommerville, this is one event the whole family will enjoy. Join fellow Marshmallow Fluff lovers and celebrate all things fluff. There will be music, there will be games, and there will be plenty of fluffy goodies! Sign up for updates about the festival so you don't miss any upcoming announcements.

For those who grew up eating fluffernutter sandwiches, you'll probably find some around the festival too. And don't forget to pick up some of your very own Marshmallow Fluff merch. There will be plenty of vendors selling themed merch for you to take home. If you just can't wait, head over to the online store and grab some merch early!

If you wish to attend at least one event this fall, make it the What the Fluff? Festival? Sometimes there's just nothing better than Marshmallow Fluff!

Will you attend the sweetest, fluffiest, and best fall festival in Massachusetts this year? Did you grow up eating peanut butter and fluff sandwiches? I know I did (and still do!). Mark your calendars for the 2025 What the Fluff Festival: September 20, 2025, from 2 p.m. until 6 p.m.
