Shake Shack introduced the Reese’s Peanut Butter Cup Shake, a Halloween-themed dessert featuring vanilla frozen custard blended with Reese’s Creamy Peanut Butter and fudge and finished inside a crackable dark chocolate shell. The shake is topped with whipped cream, Mini Reese’s Peanut Butter Cups and chopped Reese’s Pieces.
The chain lists the Reese’s shake at 1,900 calories, a figure the menu pairs with its nutrition guide. For context, Shake Shack’s Vanilla Shake is 680 calories, Chocolate is 750 calories and Cookies & Cream is 850 calories.
The offering delivers a textural payoff as diners crack through the chocolate shell into peanut-butter-fudge custard, making it a clearly indulgent treat for seasonally minded shoppers. It is available nationwide for a limited time.
