What is a common characteristic of a malted milk shake?

A common characteristic of a malted milk shake is that it contains malt powder. Malt powder is derived from malted barley and is known for adding a distinct, rich flavor and a slightly textured quality to the shake. This ingredient is what sets malted shakes apart from regular milkshakes, enhancing the overall taste experience. The inclusion of malt powder contributes to a creamier, more flavorful beverage, making it a popular choice for many milkshake enthusiasts.

The other options, such as the inclusion of fruit, the requirement for whipped cream, and the vegan-friendly classification, do not define a malted milk shake. Malted milk shakes can certainly come with toppings like whipped cream but are not dependent on it; they also typically do not contain fruit unless specifically added. Additionally, traditional malted milk shakes are made with dairy products, making them unsuitable for those following a vegan diet.
