Reese’s® Peanut Butter Cup Shake at Shake Shack
September 1-October 31, 2026
Shake Shack is turning America’s #1 Halloween candy into a shake — introducing the new Reese’s® Peanut Butter Cup Shake.
Reese’s reigns as Halloween’s top treat.* The new shake reimagines the brand’s iconic Peanut Butter Cup as a hand-spun custard shake, built in Shake Shack’s signature crackable chocolate shell format. Guests crack through a hard chocolate shell to reach a peanut butter cup-inspired center, delivering a similar experience of eating the candy itself, just frozen. It’s a treat to work into the Halloween rotation all season long.
Reese’s® Peanut Butter Cup Shake: Vanilla frozen custard hand-spun with Reese’s® Creamy Peanut Butter and fudge sauce, poured in a crackable dark chocolate shell, topped with whipped cream, Reese’s® Mini Peanut Butter Cups and chopped Reese’s Pieces®.
