A two-pound box holds the sweetness of connection, yet too much leaves a mess for someone else to clean. As you lift the corner of the box, peeking in, a fine powder greets you. This Domino’s quality is what your recipes call for, though another brand may differ in grind.

About 8 cups of sugary snow fill the box, waiting to sweeten, though the sift takes a cup or more away. Whether dusted over cream pies, stirred into glazes, or beaten into frosting, the contents connect bakers to memories made perfect with a dusting of sweet.

Measuring Powdered Sugar

Measuring Powdered Sugar
When it comes to accurately measuring powdered sugar, weight is more precise than volume. Before scooping into the measuring cup, be sure to sift the powdered sugar first to break up any lumps and aerate it for an accurate cup measurement.

A standard 16 ounce box of Domino’s powdered sugar contains about 4 cups sifted or 3 1/2 cups unsifted powdered sugar. However, weighing it on a kitchen scale will give you the most accurate measurement for recipes, especially when baking.

Volume Vs Weight

Since spoons scoop sums that sway, sailor, sift to secure the sweetness. Whether withdrawn by weight or volume, flour and sugar differ. Though cups seem quicker, scales surpass spoons. For finest finales, measure major ingredients by mass.

Despite appearances, densities deceive. Anticaking agents affect volumes unpredictably.


You’ll want to sift the powdered sugar before measuring to get a more accurate cup measurement.

  1. Breaks up any lumps.
  2. Aerates the powder into a finer consistency.
  3. Allows you to stir up settled powder for accurate measuring.

Sifting leads to smooth, lump-free powdered sugar that blends easily into frosting, glazes, and candy recipes. Simply whisk or sieve right before use for the best results. Stirring also helps incorporate any settled powder.

Types of Powdered Sugar

You’d better double-check that box of Domino’s – it’s not the same as regular powdered sugar. Domino’s goes through an extra winterizing process to prevent clumping, making it less ideal for baking. The cornstarch they add creates a finer, dustier grind that’s great for decorating cakes but can throw off recipes needing volume.

For pound cakes and lemon shortbread cookies calling for powdered sugar, stick to good ol’ confectioners made from beet sugar. Its finer 6X grind ensures it blends smoothly into butter and sugar. And if you need an ultra-fine dusting powder, reach for 10X.

Just don’t swap it cup for cup in your trusted recipes. With powdered sugars, texture impacts volume as much as weight.

Uses for Powdered Sugar

Uses for Powdered Sugar
Powdered sugar’s fine texture makes it perfect for dusting cakes and icing without the grit of granulated sugar. Over 4 cups sifted powdered sugar equals 1 lb, so a standard 2 lb box contains about 9 cups – plenty for baking cookies, cakes, and candy! Dress up your next crustless pie with a dusting of powdered sugar.

Roll fresh strawberries in powdered sugar for an easy dessert. Whip powdered sugar into stiff peaks to make homemade marshmallows. Get that classic satin sheen on your icing using powdered sugar. Roll out homemade donuts and coat in a light layer of powdered sugar.

While powdered sugar starts as cane sugar, its ultra-fine grind sets it apart. Measure powdered sugar correctly for your recipe – packing it into a cup gives too much. Level with a knife for an accurate cup. Sift to remove lumps before measuring. Though similar to granulated sugar, powdered sugar dissolves instantly and measures differently by volume.

Substituting Powdered Sugar

Substituting Powdered Sugar
You can substitute 1 3/4 cups powdered sugar for 1 cup granulated sugar in recipes calling for granulated sugar. When a recipe calls for granulated sugar but you only have powdered sugar on hand, you can make it work with a simple substitution.

For every 1 cup of granulated sugar, use 1 3/4 cups powdered sugar. It dissolves instantly and provides the sweetness needed.

Always sift powdered sugar before measuring to remove lumps. Be sure to level off the measuring cup so you get an accurate amount. Don’t pack it down. Store powdered sugar in an airtight container in a cool, dry place to prevent clumping.

Frequently Asked Questions (FAQs)

How long does an opened box of powdered sugar stay fresh?

Here’s the scoop. An opened box of powdered sugar will stay fresh for up to 1 year if stored in an airtight container in a cool, dry place. To maximize freshness, press out all the air before sealing and keep it away from humidity.

Sugar tends to clump up if exposed, so give it a good sift before using after a while.

Can you use powdered sugar that has hardened or formed lumps?

Yes, you can definitely use powdered sugar that has hardened or formed lumps. Simply sift it through a fine mesh sieve to break up any clumps before measuring. Stirring and sifting also help incorporate the anticaking agents and prevent further clumping.

What is the difference between powdered sugar and confectioners’ sugar?

There’s no difference – powdered and confectioner’s are the same sugar. It’s granulated sugar ground to a fine powder with some cornstarch added to prevent caking. The key for baking is to sift it first to remove any lumps for accurate measuring.
