How to Measure Powdered Sugar Correctly
Powdered sugar should be spooned and leveled, never packed. It compacts easily and will give inaccurate measurements if pressed.
Sift powdered sugar before making frosting or glazes to remove any lumps.
Powdered sugar contains about 3% cornstarch to prevent caking - this affects thickening in recipes.
658g of powdered sugar is about 5 cups - that's 5 full cups plus a full cup of another.
Why Accurate Powdered Sugar Measurement Matters in Baking
A 10g error when measuring powdered sugar can change your result by 0.09 cups. That's the difference between a perfectly balanced recipe and one that turns out too dry or too wet.
Adding just 10 extra grams of powdered sugar (the weight of about one tablespoon) absorbs extra moisture and can turn a tender result into a dense, dry one. Conversely, using 10g less means your structure may not hold.

Frequently Asked Questions - Powdered Sugar Conversions
Using the Spoon & Level method (recommended), 658g of Powdered Sugar equals 5½ cups. With the Dip & Sweep method, it's 4⅝ cups, and when sifted it measures 6½ cups. We recommend weighing ingredients for best results, but if you're using measuring cups, the Spoon & Level method is the most accurate.
Yes, significantly. The same 658g of Powdered Sugar can measure anywhere from 4⅝ cups (dip & sweep) to 6½ cups (sifted) - that's a 33% difference. This happens because dip & sweep compresses the ingredient, fitting more into each cup, while sifting aerates it. For consistent baking results, always use the same method your recipe specifies.
Use the Spoon & Level method: fluff the Powdered Sugar in its container first, then lightly spoon it into your measuring cup until slightly overflowing. Level off the top with the flat edge of a knife. Never scoop directly from the bag - this compresses the ingredient and you'll end up with up to 20% more than intended.
It depends on how you measure. Using the Spoon & Level method, 1 cup of Powdered Sugar weighs approximately 120g. With Dip & Sweep, it's heavier at about 142g per cup. Sifted Powdered Sugar is lighter - about 102g per cup. This is why professional bakers prefer weighing ingredients in grams.
Not exactly. 5 cups of Powdered Sugar weighs approximately 600g. 658g equals about 5½ cups - roughly 58g more than 5 full cups. For precision in baking, it's worth measuring the exact amount rather than rounding to the nearest cup.
Yes. Sifting introduces air into the Powdered Sugar, making it lighter and fluffier. One cup of sifted Powdered Sugar weighs only about 102g, compared to 120g for spoon & level and 142g for dip & sweep. If your recipe calls for '1 cup sifted Powdered Sugar,' you need less by weight than '1 cup Powdered Sugar, sifted.'
Yes, powdered sugar and confectioners sugar (also called icing sugar) are the same product. One cup weighs about 120g. It contains about 3% cornstarch to prevent clumping, which can slightly affect thickening in recipes.
658g of Powdered Sugar contains approximately 2560 calories, 656.7g carbohydrates, 0g protein, and 0g fat. Per cup (spoon & level), that's about 467 calories. Values based on USDA nutritional data.
Yes. Blend granulated sugar in a high-speed blender or food processor for 30-60 seconds until it reaches a fine powder. Add 1 teaspoon of cornstarch per cup to prevent clumping. The weight stays the same - 658g of granulated sugar makes 658g of powdered sugar.
