Shake Shack’s Halloween Treat: Buy One Double ShackBurger, Get One Free

<p>Now through Halloween, the burger chain’s final October promo doubles your ShackBurger fun in Dallas and beyond.

Shake Shack is leaning into spooky season with one last trick—or treat—of a deal. From October 22 through Halloween night, customers can purchase one Double ShackBurger and get another one free by using promo code “SPOOKY.” The offer works when ordering through the Shack app, online, or at in-store kiosks, and it’s available at participating U.S. locations—including Dallas-area Shacks in Uptown, Knox Street, Preston Royal, Plano Legacy West, and beyond.

The Double ShackBurger is no modest slider. It stacks two quarter-pound 100% Angus beef patties, American cheese, lettuce, tomato, and the chain’s signature ShackSauce on a toasted potato bun. Typically priced around $11, the deal turns this into two hearty burgers for the price of one—a solid pre-Halloween feast or a reason to treat a friend.

This promotion wraps up the chain’s month-long “Scary Deals All October” campaign. Earlier in the month, Shake Shack offered two-for-one SmokeShacks (October 1–11) and Chicken Shacks (October 12–21). The final stretch, running through October 31, celebrates the Double ShackBurger before the calendar flips to November.

Shake Shack’s blog details how to snag the freebie: add two eligible burgers to your cart, enter the promo code “SPOOKY,” and the second sandwich is automatically discounted. The offer excludes paid add-ons like bacon or avocado and doesn’t apply at certain venues such as airports, stadiums, travel plazas, or museums. Drive-thru orders and third-party delivery apps don’t qualify.

Beyond the burger BOGO, the Shack app is also rolling out smaller perks this month: $1 sodas, $3 fries, and $5 shakes. No codes needed. It’s part of the chain’s effort to pull more guests into its digital ecosystem while keeping the spirit festive and fast.

For Dallas diners, the timing couldn’t be better. With Halloween parties, concerts, and neighborhood trick-or-treating around the corner, this deal makes for an easy lunch stop or post-event bite. Grab a friend, split the fries, and double up on ShackSauce before this one vanishes after October 31.

Order now through the Shake Shack app or online to claim your BOGO Double ShackBurger deal before the clock strikes midnight on Halloween.
