Shake Shack has launched a new limited-edition shake inspired by Reese's Peanut Butter Cups, available nationwide starting September 1. The shake is designed to capture the iconic chocolate and peanut butter combination of the popular Halloween candy.
John Karangis, Shake Shack's Executive Chef and Vice President of Culinary Innovation, stated that the culinary team aimed to recreate the "crack-and-bite" experience of the candy in a shake. This version features a dark chocolate shell that customers break through to reach a peanut butter cup-flavored center. It is also topped with miniature peanut butter cups and crushed Reese's Pieces.
The new shake pays homage to Reese's, a brand that has been producing its candy since the 1920s. According to Numerator data, Reese's was named America's favorite Halloween candy last year, with the highest household penetration rate among candy brands.
Shake Shack has been actively updating its menu with new and returning items. Recent additions include a Biscoff Cookie Butter Tiramisu Shake and a limited-time Sparkling Cherry Limeade. The chain also brought back the Big Shack burger, a larger version of McDonald's Big Mac, and introduced the West Coast Burger, featuring a quarter-pound angus beef patty with caramelized onions and honey mustard pickles, topped with a new "Secret Sauce."
These menu innovations appear to be contributing to the company's financial performance. In the last quarter, Shake Shack reported $417.6 million in earnings, a 17.2 percent increase compared to the previous year, with same-Shack sales rising by 3.5 percent. Customer traffic also increased by 2 percent, marking the fourth consecutive quarter of growth.
The company experienced its strongest second-quarter unit growth on record, opening 16 company-operated Shacks and 11 licensed locations during the quarter. However, net income saw a slight decrease to $16.9 million from $18.5 million a year earlier, and the restaurant-level profit margin fell to 23 percent from 23.9 percent. Shake Shack cited "real headwinds," including inflation and competitive pressures, as factors impacting profitability but expressed confidence in navigating these challenges and achieving long-term growth.
