What do they put in McDonald's milkshakes?

3 min read

McDonald's shakes are often not legally classified as 'milkshakes' in some US states due to varying dairy regulations, but people still wonder what do they put in McDonald's milkshakes to make them so thick and creamy. The answer lies in a combination of a specialized reduced-fat soft serve base, flavor syrups, and a blend of stabilizers.

Quick Summary

A McDonald's shake is made from a reduced-fat soft serve dairy base, which includes milk, sugar, cream, and corn syrup, combined with flavored syrups and a blend of stabilizers for thickness. The final product is topped with whipped light cream and served thick and cold.

Key Points

  • Not all ice cream: McDonald's shakes use a reduced-fat soft serve base, not traditional ice cream, which is why they are called 'shakes' in some areas.

  • Core ingredients: The base includes milk, cream, sugar, corn syrup, and various stabilizers.

  • Flavor comes from syrup: The flavor for shakes like chocolate or strawberry is added via a concentrated syrup mixed into the vanilla soft serve.

  • Stabilizers are key: Additives like guar gum and carrageenan are used to create the signature thick, creamy, and smooth texture.

  • Regional variation: Ingredient lists can differ slightly between countries due to local regulations and sourcing.

  • Topping is whipped cream: The shake is topped with a whipped light cream containing cream, nonfat milk, and more stabilizers.

The Core of a McDonald's Shake: The Dairy Base

At the heart of every McDonald's shake is its signature reduced-fat vanilla soft serve. Unlike a traditional shake made with scooped hard ice cream, McDonald's uses a soft-serve mix that contributes to the final drink's light, airy, and creamy consistency. The main ingredients of this base are:

  • Milk and cream
  • Sugar and corn syrup
  • A variety of stabilizers, such as guar gum, cellulose gum, and carrageenan
  • Natural flavors and other additives like Vitamin A Palmitate

The 'Ice Cream' Controversy

In some regions, McDonald's shakes are not referred to as 'milkshakes' for legal reasons tied to dairy regulations, specifically concerning milkfat content. The use of a proprietary reduced-fat soft serve mix, rather than a standard ice cream with a specific butterfat content, leads to this distinction. This semantic difference doesn't impact the delicious taste but explains why the menu item is simply called a 'shake'.

Deciphering the Flavor Syrups

Each shake flavor, from classic chocolate to seasonal specials, gets its signature taste from a proprietary syrup mixed with the vanilla soft serve. The syrups add concentrated flavor and additional sweetness.

Common Shake Flavors and Their Ingredients

  • Vanilla Shake Syrup: This syrup typically contains corn syrup, water, vanilla extract, and preservatives.
  • Chocolate Shake Syrup: Ingredients in this syrup include sugar, corn syrup, water, cocoa (processed with alkali), and natural flavors.
  • Strawberry Shake Syrup: This syrup features sugar, water, corn syrup, high fructose corn syrup, and concentrates like strawberry and fruit juice for color.

Additives and Stabilizers

To achieve the distinct texture and mouthfeel, McDonald's shakes utilize several additives and stabilizers. These components play a crucial role in preventing separation and maintaining a consistent product.

Why Stabilizers are Important

Stabilizers and emulsifiers serve several key functions in the soft serve mix and shake product:

  • Preventing ice crystal growth: Ingredients like guar gum and carrageenan help keep the texture smooth and free of large ice crystals.
  • Maintaining thickness: These agents create a consistent viscosity, giving the shake its signature thickness.
  • Improving shelf life: They help maintain product quality during storage before being blended into a shake.

A Comparison of Shake Ingredients

While the core dairy base is similar globally, regional variations exist based on local regulations and ingredient sourcing. Here is a comparison of some key ingredients found in different countries.

Conclusion

While mystery often surrounds what they put in McDonald's milkshakes, the official ingredient list shows a combination of a reduced-fat vanilla soft serve base, flavored syrups, and a specific blend of stabilizers and emulsifiers. The resulting beverage achieves its characteristic smooth, thick, and creamy texture without using traditional hard ice cream. This approach, alongside regional ingredient variations, ensures a consistent product worldwide, even if it's legally called a 'shake' rather than a 'milkshake' in many places.
