@jazzy_foodz: The Shake Shack Reese's Peanut Butter Cup Shake is a limited-time Halloween-themed treat launched nationwide on September 1, 2026. It has gone viral for its decadent flavor profile and massive 1,900-calorie count. What's Inside the ShakeBase: Hand-spun vanilla frozen custard blended with real Reese's Creamy Peanut Butter and fudge sauce. The Shell: Poured inside a signature hard, crackable dark chocolate shell that you have to smash with a spoon to get to the shake. Toppings: Topped with a cloud of whipped cream, Reese's Mini Peanut Butter Cups, and chopped Reese's Pieces. Have you tried it yet? Are you a Reese's fan?
