What is powdered sugar?

Powdered sugar, confectioner’s sugar, and icing sugar are different terms that describe sugar used for decorative and dusting purposes when baking. Powdered sugar is the preferred form of sugar when baking. It gives your dish a perfect snowfall appearance.

Moreover, it is more preferred over granulated sugar because it makes baked goods softer and denser. Powdered sugar is granulated sugar that has been processed with cornstarch into a powdery, light, and fluffy sugar.

Bakers prefer powdered sugar because it dissolves quickly and mixes well with almost anything. Also, it doesn’t clump together because of the cornstarch it contains.

In addition, powdered sugar is what gives baked goods a melt-in-your-mouth effect that you enjoy in some sweets and other foods. It is the sugar used in making frostings, icings, fudges, glazes, ice creams, and cakes.

  • Hold the sifter over a dry bowl and sift gently
  • Afterward, heap the sugar into a dry measuring cup but do not compress it
  • Then, level the heap with the back of a knife until it is the same level as the cup
  • Once you have a leveled cup of sugar, turn it into the mixing bowl

Can you substitute powdered sugar with granulated sugar?

You can substitute powdered sugar with granulated sugar. Replace 1¾ cup of powdered sugar with 1 cup of granulated sugar.

However, granulated sugar leaves air pockets in your baked goods and does not make them soft and dense. Icing, in particular, does not come out smooth with granulated sugar.

Do you measure powdered sugar and granulated sugar the same way?

Yes, you do. You can measure powdered and granulated sugar with the same measuring cup. Then, use a knife to level off the edges to keep them as flat as the top of the cup.


If you don’t employ much mathematics when using other cooking methods, you won’t escape it with baking. And some measurements you think are standard do not always apply to all ingredients, even when they are in the same form.

The right information is a major ingredient in any recipe. Ingredients like salt, sugar, and pepper do not need assumptions. Have the correct measurements and work with them, then you will have a perfect dish.
