Observed each year on September 12 in the USA, this food holiday is dedicated to indulging in and enjoying chocolate milkshakes, typically made with milk, chocolate ice cream or chocolate syrup, and sometimes additional flavorings like whipped cream, chocolate chips, or sprinkles.

The origins of milkshake date back to the late 1800s when the term referred to a whiskey-based drink similar to eggnog.

Since then, milkshakes have became associated with flavored syrups like chocolate, vanilla, and strawberry, often served with ice cream.

The invention of the electric blender in 1922 revolutionized the preparation of milkshakes, making them frothier and more accessible.

Enjoy a chocolate milkshake this day at a local ice cream parlor or restaurant, or blend your own at home with ice cream, milk, and chocolate syrup topped with whipped cream and perhaps a cherry or mint sprig for garnish.
