“Make it malted” means adding malted milk powder to a milkshake or other drink. That single ingredient transforms a regular milkshake into a malt (sometimes called a “malted”), giving it a thicker consistency and a distinctive toasty, slightly nutty sweetness. If you’ve ever heard this phrase at an ice cream shop or diner counter, it’s simply a request to stir in a scoop or two of this tan-colored powder.
What Malted Milk Powder Actually Is
Malted milk powder is made from three core ingredients: malted barley, wheat flour, and evaporated whole milk. The “malted” part refers to barley grain that has been soaked in water for two to three days until it sprouts, then kiln-dried to stop the process. During sprouting, enzymes inside the grain convert its starches into sugars, which is what produces that characteristic sweet, caramelly flavor.
Once dried and ground, the malted barley is combined with wheat flour and powdered milk, creating a shelf-stable powder you can spoon into drinks, batters, or desserts. The most recognizable brands are Carnation and Horlick’s. William Horlick originally invented the product in 1873 as a nutritional supplement. Physicians prescribed it, and explorers carried it on expeditions to the North Pole and the Himalayas before it found its true calling at the soda fountain.
How a Malt Differs From a Milkshake
A standard milkshake is ice cream blended with milk and sometimes flavored syrup. A malt is all of that plus malted milk powder. The powder does two things: it thickens the shake noticeably, and it adds a layer of flavor that’s hard to replicate with anything else. Think roasted grain, caramel, and a faint biscuit-like warmth underneath whatever main flavor you’ve chosen.
Chocolate malts are the classic order because chocolate and malt complement each other well, but vanilla and strawberry malts have their loyalists too. If you’re at a place that offers the option, asking them to “make it malted” typically adds one to two tablespoons of the powder per serving.
What “Malted” Means Beyond the Milkshake
The word “malted” shows up across a surprisingly wide range of foods, and it always traces back to the same process: grain that has been sprouted and dried.
In brewing, malted barley provides the sugars that yeast ferments into alcohol. In baking, malt comes in several forms. Diastatic malt powder still contains active enzymes that break down flour starch into sugar, giving yeast more to feed on and producing a faster rise, deeper color, and better flavor. It’s commonly blended into bread flour before it even reaches your kitchen. Non-diastatic malt powder has had those enzymes deactivated through higher heat, so it contributes flavor and color without affecting fermentation. Barley malt syrup, a thick and dark liquid, is what gives a good bagel its amber, shiny crust when added to the boiling water.
Then there are malted candies. Whoppers and Maltesers both build their crunchy centers around malted milk (barley malt, wheat flour, milk, salt, and baking soda), which is puffed and then coated in chocolate. That light, airy crunch is the malted milk powder doing its thing in solid form.
The Flavor Profile
Malt flavor is easier to recognize than describe. It sits somewhere between toasted bread, honey, and butterscotch, with a slight grain quality that keeps it from being simply sweet. The chemistry behind it involves the same browning reactions (called Maillard reactions) that give bread crust, roasted coffee, and seared steak their complex flavors. When the sprouted grain is kilned, those sugars and amino acids react under heat to produce dozens of aromatic compounds.
This is why malted milk powder works so well as a flavor enhancer in recipes that might otherwise taste flat. America’s Test Kitchen recommends starting with about one tablespoon per serving and adjusting from there. They suggest tossing it with popcorn for a sweet-savory contrast, stirring it into cream before whipping it, or adding it to simple custard sauces. The powder shines brightest in recipes with straightforward flavors where it won’t get buried.
Nutrition at a Glance
Malted milk powder is calorie-dense, as you’d expect from a combination of grain and dried milk. An eight-ounce glass of chocolate malted milk made with whole milk delivers a solid dose of phosphorus (about 241 mg, roughly a quarter of your daily need), along with meaningful amounts of vitamin B12 and selenium. It was originally marketed as a way to get concentrated nutrition into a portable format, and that rationale holds up. It’s not a health food by modern standards, but it’s not empty calories either.
Using Malt Powder at Home
If you want to make your own malted milkshake, blend two scoops of ice cream with a half cup of milk and two to three tablespoons of malted milk powder. That’s it. Carnation Original Malted Milk Powder is the easiest to find in most grocery stores, usually in the baking aisle or near the hot cocoa mixes.
For baking, keep in mind the distinction between diastatic and non-diastatic. If a bread recipe calls for malt powder, it almost always means diastatic, and you need very little. Bread expert Jeffrey Hamelman recommends starting at just 0.1 to 0.2% of the flour’s weight, because too much diastatic malt produces a gummy, unpleasant crumb. Non-diastatic malt powder is more forgiving and can be added more generously to cookies, pancake batter, or waffles for that toasty depth.
