How Many Grams of Powdered Milk Are in a Cup

ByGlosaria

A standard cup of powdered milk weighs 68 grams. This figure varies slightly depending on whether the milk is whole or skim and how compacted it is when measured, but 68 g is the most commonly used reference in baking recipes. If you need the exact figure for your recipe, keep reading.

Grams of powdered milk in a cup: the quick table

When we talk about grams of powdered milk in a cup, we mean the standard US measuring cup of 240 ml, the one used in most recipes translated from English. These are the most common equivalents:

  • 1 cup of whole powdered milk: 68 g
  • 3/4 cup: 51 g
  • 1/2 cup: 34 g
  • 1/3 cup: 23 g
  • 1/4 cup: 17 g
  • 1 tablespoon: 4.25 g

These figures correspond to uncompressed powdered milk, meaning it’s spooned into the cup without pressing it against the container.

How much does a cup of powdered milk weigh depending on the type

Not all powdered milk weighs the same. Density depends on fat content and the drying process (spray or roller):

  • Whole powdered milk: 68 g per cup
  • Skim powdered milk: 60-65 g per cup (finer, lighter particles)
  • Baby formula powder: between 70 and 90 g per cup, depending on the brand

If your recipe doesn’t specify the type, assume it refers to whole powdered milk for baking, which is the most common in bakeries and homemade recipes.

Why powdered milk isn’t measured the same way as flour

Powdered milk has a fine, somewhat clumpy texture, different from flour or sugar. This means that if you compact it while measuring, you can fit up to 15% more product in the same cup, throwing off the recipe. The correct technique is:

  • Aerate the powdered milk by stirring it with a spoon before measuring
  • Spoon it into the measuring cup without pressing down
  • Level the surface with the back of a knife, without shaking the cup

This method is the same one recommended for measuring grams of flour in a cup, and it prevents your recipes from turning out denser than they should.

Powdered milk cup to grams conversion: from cups to tablespoons

Many recipes call for small amounts of powdered milk, especially in homemade baking. This table helps you out when you don’t have a measuring cup on hand:

  • 1 tablespoon = 4.25 g
  • 2 tablespoons = 8.5 g
  • 4 tablespoons = 17 g (equals 1/4 cup)
  • 8 tablespoons = 34 g (equals 1/2 cup)
  • 16 tablespoons = 68 g (equals 1 cup)

If your scale only shows ounces or you need to convert grams to that unit for a recipe imported from the US, you can use Glosaria’s convert grams to ounces tool and get the exact result instantly.

Differences between measuring with a scale and with a cup

A digital scale always wins in precision over a measuring cup. With powdered milk, the difference between measuring correctly or incorrectly with a cup can reach 10 grams, which matters in recipes where powdered milk provides structure, such as brioche breads or artisanal ice cream. If you bake frequently, investing in a kitchen scale with 1 g precision solves this problem at its root.

What powdered milk is used for in baking

Powdered milk isn’t just a substitute for liquid milk. It’s deliberately used in many recipes because:

  • It adds more protein and milk sugars without adding water, which improves the browning of breads and cookies
  • It gives body and creaminess to ice cream without using more fat
  • It’s used in bread dough to achieve a softer, more tender crumb
  • It allows you to adjust a dough’s texture without unbalancing the total hydration

That’s why measuring it precisely matters so much: it’s not a decorative ingredient, it serves a technical function in the recipe.

How to substitute powdered milk for liquid milk (and vice versa)

If a recipe calls for powdered milk and you only have liquid milk, or vice versa, this equivalence will guide you:

  • 1 cup of liquid milk = 3-4 tablespoons of powdered milk (34 g) + 1 cup of water
  • To reconstitute 68 g of powdered milk (1 cup), add approximately 240 ml of water

Keep in mind that substituting this way will add some extra water compared to the original recipe, so adjust the flour slightly if the dough turns out too wet.

Common mistakes when measuring powdered milk

The most frequent mistakes when calculating grams of powdered milk in a cup are:

  • Using a tea cup (approx. 200 ml) instead of the 240 ml measuring cup
  • Compacting the powder while filling the cup, which adds extra weight unintentionally
  • Confusing powdered milk with powdered condensed milk, which has more sugar and weighs differently
  • Not aerating the product before measuring, especially if it’s been open for a while and has clumped

Frequently asked questions

How many grams of powdered milk are in a cup?

A standard 240 ml cup of whole powdered milk weighs 68 grams. If it’s skim powdered milk, the weight can drop to 60-65 grams because its particles are finer and lighter.

How much does a cup of compressed powdered milk weigh?

If you compact the powdered milk while filling the cup, it can end up weighing between 75 and 80 grams, 10-15% more than if measured aerated and without pressing. That’s why it’s recommended not to pack the product down when measuring it.

How do I convert a tablespoon of powdered milk to grams?

One tablespoon of powdered milk equals approximately 4.25 grams. Sixteen tablespoons make up a 68-gram cup.

Does baby formula powder weigh the same as baking powdered milk?

No. Infant formula powder usually weighs between 70 and 90 grams per cup, depending on the brand, due to its different nutritional composition compared to standard cooking powdered milk.

Can I substitute powdered milk for liquid milk in a recipe?

Yes. To substitute 1 cup of liquid milk, use 3 to 4 tablespoons (34 grams) of powdered milk dissolved in 1 cup of water. The result is practically equivalent in flavor and function within the recipe.
