How Many Cups of Confectioners Sugar Are in a Pound? (Everything You Need to Know)

If you’ve ever followed a baking recipe that calls for confectioners sugar (also known as powdered sugar, icing sugar, or confectioners’-grade white sugar), you may have found yourself wondering: How many cups are in a pound? Understanding the conversion is essential whether you’re scaling a recipe up or stocking up sugar supplies.

The Simple Answer

There are approximately 3 to 4 cups of confectioners sugar in one pound, depending on how finely the sugar is ground.

Understanding the Context


What Is Confectioners Sugar?

Confectioners sugar is white granulated sugar that has been finely ground and often treated with a small amount of cornstarch to prevent clumping. It’s commonly used for decorating cakes, making frostings, glazes, and candies.


Why the Variability in Cups?

The number of cups per pound hinges on two main factors:

  • Sugar fineness: Commercial confectioners sugar is very finely ground, but some homemade or specialty varieties may be coarser, affecting yield.
  • Packing method: A cup of powdered sugar poured loosely can hold up to 4 cups, while packed sugar (pressed firmly into the measuring cup) yields about 3 cups per pound.

Breakdown by Measurement

To clarify:

| Measurement | Cups per pound (approximate) |
|----------------------|-------------------------------|
| Loose packing (powdered) | 4 cups |
| Leveled packing (1 tbsp = ~2.5g) | 3 cups |
| Superfine or stored coarser sugar | Slightly less (closer to 3 cups) |


Practical Tips for Home Bakers

  • Always level your measuring cup for powdered sugar to get accurate results.
  • If a recipe says “2 cups confectioners sugar,” that’s about 1.5 pounds — ideal for frostings and glazes.
  • For frostings, using closely packed sugar ensures the right thickness and consistency.
  • Store confectioners sugar in an airtight container to keep it powdery and prevent clumping.
