Fortified Milkshake Recipe: Creamy, Easy and Customizable

This fortified milkshake blends cold milk, vanilla ice cream, and dry milk powder into a thick, smooth drink with extra milk solids. It comes together in minutes, and the powder makes the shake creamier without needing extra ice cream. This recipe makes two servings and is easy to adjust with fruit, cocoa, or other flavors.

Ingredients

Use cold ingredients for the thickest texture, and measure the dry milk powder before adding it to the blender. Here, fortified means the shake is enriched with dry milk powder; the powder does not necessarily contain added vitamins or minerals.

1 1/2 cups vanilla ice cream (about 225 g), slightly softened for easier blending
1 cup cold whole milk (240 ml)
1/3 cup nonfat dry milk powder (about 35 g)
1/2 teaspoon vanilla extract (2.5 ml)
1 small pinch fine salt (about 0.2 g), optional, to balance the sweetness
1 teaspoon granulated sugar (4 g), optional; add only if you prefer a sweeter shake

Choose plain, unsweetened dry milk powder rather than a sweetened drink mix. Dry milk powder varies a little in density, so spoon it into the measuring cup and level it rather than packing it down. If you have only whole-milk powder, use the same measured amount by volume; it will make the shake richer, and the finished texture may be slightly heavier.

Instructions

Chill and measure. Make sure the milk is cold, then measure the ice cream, milk, dry milk powder, and vanilla. If the ice cream is very firm, leave it at room temperature for 2 to 3 minutes so it can scoop easily, but do not let it melt into a puddle.
Start with the liquids. Pour the milk and vanilla into the blender jar. Add the dry milk powder and salt, if using. Blending the powder with the liquid first helps prevent dry pockets from sticking to the sides or collecting beneath the blades.
Add the ice cream. Spoon in the vanilla ice cream. If you want a sweeter shake, add the optional teaspoon of sugar now. Keep the blender below its maximum fill line; if your jar is small, blend the recipe in two batches rather than overfilling it.
Blend until smooth. Blend on low for about 10 seconds, then increase to medium for another 15 to 25 seconds. Stop when the shake looks even and no dry powder is visible. Avoid running the blender longer than needed, since excess blending warms the mixture and can make it looser.
Check the consistency and serve. If the shake is too thick to pour, add cold milk 1 tablespoon (15 ml) at a time and blend briefly after each addition. If it is thinner than you like, add 1 to 2 tablespoons (15 to 30 g) of ice cream and blend just until combined. Pour into two chilled glasses and serve right away.

The listed amount of milk is a starting point, not a requirement to use every drop if your ice cream is particularly soft. For a spoon-thick shake, begin with 3/4 cup milk (180 ml) and add more only as needed. If your blender struggles, pause it, switch it off, and use a spatula to move the mixture toward the blades; never put a utensil into a running blender.

Tips

Keep the powder lump-free. Add it to the milk before the ice cream, and blend briefly before continuing if you can see clumps. If the powder is old or has absorbed moisture, break up any lumps with a fork or sift it first. This small step helps the finished drink taste smooth rather than dusty.
Adjust thickness gradually. Ice cream brands and freezer temperatures differ, so the same recipe can pour differently from one batch to another. Add milk a spoonful at a time instead of pouring in a large extra splash. It is easy to loosen a thick shake, but restoring thickness usually takes more ice cream and can make the drink sweeter.
Use the right powder. Plain dry milk powder is the most predictable choice. Malted milk powder is a possible substitute, but it contains sweetener and flavoring, so the shake will taste maltier and may need no extra sugar. Do not substitute a flavored infant formula or a medical nutrition product; those are not general-purpose recipe ingredients.
Scale without straining the blender. For four servings, double every ingredient and blend in batches if needed. A crowded blender may leave powder unincorporated and warm the shake before it becomes smooth. For a single serving, halve the quantities and use a narrow blender cup if your appliance has one.

Serving Suggestions

Serve the milkshake immediately in chilled glasses, while it is cold and thick. A reusable straw works well for a pourable shake; offer a long spoon if you have blended it on the thicker side. For a simple finish, add a small swirl of whipped cream or a light dusting of cocoa, but keep toppings modest so they do not overwhelm the vanilla flavor.

This shake pairs nicely with a salty or crisp snack, such as pretzels, plain popcorn, or a toasted sandwich. For a dessert-style presentation, pour it into two small glasses and add a wafer or a few chocolate shavings. If serving a group, blend each batch just before it is wanted rather than leaving a full pitcher on the counter; a milkshake loses its airy texture as it warms and sits.

Variations

Chocolate: Add 1 tablespoon unsweetened cocoa powder (5 g) with the dry milk powder. Blend, taste, and add up to another 1 teaspoon sugar (4 g) if needed. Cocoa can make the mixture feel thicker, so loosen it with a little cold milk if necessary.
Banana: Blend in 1/2 medium ripe banana (about 60 g), peeled and sliced. It adds a distinct fruit flavor and makes the shake thicker, so begin with 3/4 cup milk (180 ml). A very ripe banana will taste sweeter than a firm one.
Strawberry: Add 1/2 cup hulled fresh strawberries (about 75 g) or thawed frozen strawberries, drained. Frozen fruit can make the shake extra thick; add milk gradually until it pours. The fruit will shift the flavor away from vanilla and may make the color less bright if the berries are dark.
Malted vanilla: Replace the dry milk powder with 1/3 cup malted milk powder (about 40 g), or use half malted powder and half dry milk powder. The result is sweeter and has a toasted, malty taste. Leave out the optional sugar unless you taste the finished shake and decide it needs more.
Dairy-free: Use a dairy-free vanilla frozen dessert and an unsweetened oat or soy beverage, then choose a compatible powdered product only if its package directions support blending into cold drinks. Plant-based powders vary in sweetness and thickness, so start with 2 tablespoons (about 15 to 20 g) and adjust to taste. The result will not have the same dairy flavor or texture as the original.

Storage and Reheating

A milkshake is best immediately after blending. If you need to prepare it a little ahead, pour it into a covered container and refrigerate it promptly, within 2 hours of blending. Keep it at 40°F (4°C) or colder and use it within 24 hours for the best flavor and texture. Follow the use-by guidance on the milk and ice cream packages, and discard the shake if it has been left at room temperature for more than 2 hours, or 1 hour in temperatures above 90°F (32°C).

The mixture may separate or become thinner in the refrigerator. Stir it well or blend it briefly before serving; add a small splash of cold milk if it has thickened too much. Do not reheat a milkshake. Freezing is possible for up to 1 month for best quality in a covered, freezer-safe container, but the shake will freeze solid and may turn grainy after thawing. Thaw it in the refrigerator and blend again; it may not return to its original texture.

Frequently Asked Questions

What makes this a fortified milkshake?
The dry milk powder adds concentrated milk solids to the drink. In this recipe, fortified describes that added ingredient; it does not mean the finished shake is a regulated product or that the powder necessarily contains added nutrients. Check the package label if you need to know whether a particular powder has been fortified with vitamins or minerals.

Can I make it without a blender?
Yes, if the ice cream is soft enough. Whisk the milk, dry milk powder, vanilla, and salt in a large bowl until smooth, then whisk in the ice cream a little at a time. A sturdy whisk or immersion blender works better than a spoon. The texture may be less airy, and it can take longer to remove every small powder lump.

Can I make the shake ahead for a party?
It is better to blend it close to serving time because the ice cream melts and the mixture separates as it sits. You can measure the dry ingredients and refrigerate the milk in advance, then blend individual batches when guests are ready. If you must make it ahead, keep it covered and cold, then stir or briefly reblend it before pouring.

Why does my milkshake taste powdery?
The dry milk may not have fully dispersed, or too much powder may have been packed into the measuring cup. Blend the powder into the milk before adding the ice cream, and spoon and level the powder rather than compressing it. If the shake is already blended, add 1 tablespoon (15 ml) cold milk and blend again briefly; repeat only as needed.

Can I use sweetened condensed milk instead of dry milk powder?
Not as a direct replacement. Condensed milk adds liquid and considerable sweetness, while dry milk powder adds milk solids without the same amount of liquid. If you choose to experiment, omit the optional sugar and start with only 1 tablespoon (15 ml) condensed milk, tasting before adding more. The shake will be sweeter and less thick than the version made with powder.

How can I make a thicker shake without adding more ice cream?
Begin with less milk, using 3/4 cup (180 ml) rather than the full cup, and blend just until smooth. You can add the remaining milk a tablespoon at a time if the blender needs help. You may also use a little more dry milk powder, but add it sparingly because excess powder can make the texture chalky rather than pleasantly thick.
