How Much Powdered Sugar Is in A Box? – Tips for Measuring Powdered and Confectioners’ Sugar

There’s often a bit of number-crunching and conversion involved in baking and cooking. 

If you constantly indulge in recipes that call for powdered sugar or confectioner’s sugar, or you want to cater to curiosity, you may question how much powdered sugar a box holds.

Knowing this will make your grocery choices for powdered sugar easier. 

A 1-pound or 16-ounce box of powdered or confectioners sugar holds approximately 3.5 cups of powdered sugar. 

One significant variable to consider when using powdered sugar is whether your recipe calls for the sifted or unsifted variant. If your recipe demands sifted powdered sugar, you must tweak the original recipe. 

Let us explain how. 

How much powdered sugar is in a box? 

A conventional 1 lbs box of powdered sugar contains about 16 ounces of powdered sugar. A 2 lbs box of powdered sugar follows the same math. A 2 lbs box holds approximately two 32 ounces of powdered sugar, and it goes on and on.

How many cups are in a box of powdered sugar?

A one-pound box of powdered sugar is equivalent to 3.5 to 4 cups of powdered sugar. 

Here’s a simple way to do the math; since one pound or 1lbs of powdered sugar equals 16 ounces and one cup of powdered sugar is 4.5 ounces, you will need between 3 ½ to 4 cups of powdered sugar to complete 16 ounces. 

Using this method to determine how many cups are in a two-pound box of powdered sugar, you should get about 7 to 7 ½ cups of powdered sugar in a two-pound or 16-ounce box. 

How many cups are in a pound of sugar?

One pound of powdered sugar contains about 3 ½ to 4 cups of sugar. Meanwhile, one pound of granulated sugar has approximately 2 ½’cups of sugar. 

Alternatively, one pound of brown sugar will hold approximately 2.3 cups, while a pound of raw cane sugar should hold about 2 cups. 

How many cups are in 2 lbs of sugar?

There are about 4.5 cups of sugar in 2 lbs of granulated sugar. On the other hand, there are approximately 7 to 7 ½ cups in 2 lbs of powdered sugar. 

Additionally, a 2 lbs measurement of brown sugar should be about 4.6 cups, while a 2 lbs measurement of raw cane sugar should be approximately 4 cups. 

How many cups are in a box of Domino’s powdered sugar?

Domino’s powdered sugar comes in three sizes 1 lb, 2 lbs, and 4 lbs. 

The Domino’s 1 lb box contains approximately 3 ¾ cups of powdered sugar. 

The Domino’s 2 lbs box contains about 7 ½ cups of powdered sugar. 

The 4 lbs Domino’s box contains roughly 15 cups of powdered sugar.

What is a confectioner’s sugar? 

Also known as powdered sugar, confectioners’ sugar is a well-ground sugar often sifted over pastry foods and used in frosting. 

Confectioners’ sugar has a smooth and powdered feel. This sugar variant is so soft that you can almost describe it as sugar dust. It can be called icing sugar or fondant sugar as well. 

You can find confectioners’ sugar at your local grocery store. However, if you are looking to go DIY, you can make confectioner’s sugar without leaving the comfort of your kitchen. Here’s how:

1. Add granulated sugar and cornstarch to a tough blender like a food processor. 

2. Grind until the mix reaches a powdery and smooth consistency.

3. Check the consistency of the sugar at intervals. 

4. Continue blending if it is not well-blended. 

How to measure powdered and confectioners’ sugar

The most important thing to note when measuring powdered sugar is that you should sift it before measuring it; that is, if your recipe calls for sifted sugar, of course. 

Additionally, for balancing purposes, one cup of granulated sugar equals 1 ¾ packed powdered sugar. 

Follow this process to measure powdered or confectioners’ sugar:

1. Carefully add the powdered sugar to a dry measuring cup with a spoon (don’t add all the sugar at once). 

2. Level the top of the sugar with a small knife till it evens out with the rim of the measuring cup or the level you want. 

What size of container will hold 4 lbs of sugar? 

A 2.8-quart POP container will hold 4 lbs of sugar perfectly. 

How to measure granulated sugar

Scoop out the granulated sugar from the box/container with a dry measuring cup or pour the granulated sugar into a dry measuring spoon and level the top with a small knife to prevent excess sugar. 

How many cups of confectioners’ sugar is in a pound? 

Approximately 3 ½ cups of confectioners’ sugar make up a pound or 1 lb. 

What is sifted powdered sugar?

Sifted powdered sugar is powdered sugar that is sieved to remove sugar clumps and improve the overall texture of the powdered sugar. A hand-cranked sifter is often the go-to for the sifting process.

What does a cup of sugar weigh?

One cup of granulated sugar weighs 200 grams, and a cup of powdered sugar weighs about 124 grams. 
A cup of brown sugar equals 170 grams, while a cup of raw cane sugar can weigh about 210 grams.
