The Ultimate Guide to Malted Milk Shakes: Flavor & History
A malted milkshake is a creamy beverage made with milk, malted milk powder, and ice cream, offering a rich, sweet, and nostalgic flavor.
A malted milk shake is a creamy, indulgent drink made with ice cream, milk, and malted milk powder. This powder adds a unique toasty, caramel-like flavor that elevates a regular milkshake into something extraordinary. Popular since the 1920s, malted shakes remain a nostalgic favorite at diners and soda fountains.
What Is Malted Milk Powder?
Malted milk powder is the key ingredient that gives these shakes their signature taste. It’s made from two main components:
- Malt powder: Created from germinated, dried barley grains that develop enzymes to convert starches into sugars
- Milk solids: Powdered milk that adds creaminess
When combined, these create a pale yellow powder with a nutty, slightly sweet flavor profile. Popular brands include Carnation Malted Milk and Horlicks.
How It Differs From Plain Malt Powder
While both come from malted grains, there’s an important distinction:
| Malted Milk Powder | Malt Powder (Diastatic) |
|---|---|
| Contains added milk solids | Just malted grains |
| Used for flavor in shakes/candy | Used in baking to help dough rise |
| Sweet, creamy taste | More neutral flavor |
The History Behind Malted Shakes
The story begins in the late 1800s when brothers William and James Horlick created malted milk powder as an infant nutrition supplement. By the 1920s, soda jerks at Walgreens discovered its delicious potential when blended into milkshakes.
During Prohibition, malt shops became popular gathering places since they could legally serve “near beer” malt beverages. The malted shake became their signature offering, cementing its place in American food culture.
Malted Shake vs. Regular Milkshake
While similar in preparation, these drinks have distinct differences:
- Flavor: Malted shakes have a deeper, toastier taste from the malt powder
- Texture: Both should be thick and creamy when made properly
- Nutrition: Malted versions contain slightly more protein and vitamins from the malt
For the best results, use a quality blender designed for milkshakes to achieve that perfect consistency.

Pro Tips for Better Shakes

The Science Behind Malt Flavor
The unique taste comes from chemical compounds created during malting:
- Pyrazines: Provide nutty, toasted notes
- Furans: Contribute caramel-like sweetness
- Maillard reaction products: Create complex roasted flavors
These compounds make malted shakes more complex than regular milkshakes, which rely mainly on sugar and dairy flavors.
