Dunkin’ is giving away free Halloween Bat Cup Sleeves today-here's how to get one

Dunkin’ is adding a little Halloween fun to its drinks menu, and fans can get a free collectible while supplies last. The coffee chain is giving away limited-edition Bat Cup Sleeves on October 16, but there’s a catch: you’ll need to order a specific seasonal drink. The giveaway is part of Dunkin’s Halloween lineup, which also includes a purple refresher, the returning Spider Donut and a new glow-in-the-dark Munchkins bucket.

Here’s what to know before heading to a participating Dunkin’ location, as per a report by USA Today and Dunkin's news release.

How can you get Dunkin’s free Bat Cup Sleeve?

The offer is available on Friday, October 16. Customers who purchase a Berry Battie Daydream Refresher of any size at participating Dunkin’ locations nationwide can receive a free limited-edition Bat Cup Sleeve.

The giveaway is available while supplies last, and the offer is limited to one sleeve per order. Customers do not need to buy a particular size of the drink to qualify.

The sleeve features plush purple bat wings designed to wrap around a Dunkin’ cup. It is part of the brand’s effort to bring Berry Battie, its new Halloween character, beyond the drink itself.

The Berry Battie Daydream Refresher combines berry, clementine and blueberry flavors with oat milk. It is topped with purple marshmallow cold foam and finished with candy eyes.

What other Halloween treats are coming to Dunkin’?

Dunkin’ has brought back its popular Spider Donut, also known as Spidey D, for another Halloween season. The treat features a purple-frosted donut with a Chocolate Glazed Munchkins donut hole in the center. Chocolate icing forms the spider’s legs, while vanilla-flavored icing creates its eyes.

The chain is also selling Spider Donut merchandise. Customers can purchase a Spider Donut keychain for $9.99 or a Mystery Boo Box for $8.99, which contains one surprise collectible. Options include a Spider Donut Squish, pin set, acrylic keychain or bandana.

Another returning favorite has received a new look. The Halloween Munchkins bucket comes in purple, features costumed Dunkin’ characters and glows in the dark for the first time.

Each bucket contains a random assortment of 50 Munchkins donut hole treats, including new sprinkle-covered Halloween varieties. Dunkin’ will donate $2 from every bucket sold to its Joy in Childhood Foundation, which supports children facing hunger or illness.

More spooky drinks on the menu

Dunkin’s seasonal drinks include Green Apple Dunkin’ Zero, Midnight Apple Dunkin’ Zero, Candy Kiss Dunkin’ Zero and Orchard Twist Dunkin’ Zero.
