• 4    • 9442   How many cups is 1/2 pounds of confectioner's
sugar?  Answer » nutcakes added over 2 years ago  One pound of
powdered sugar is about 3-3/4 cups measured (between 3-1/2 and 4
cups.) Sor for 1/2 pound, use 1-7/8th cup.  I disagree with the
first answer because powdered sugar comes in weight which does
not always compute to fluid ounces such as a cup measure.
lorigoldsby added over 2 years ago  I agree with nutcakes
(although I haven't gotten out the measuring cups to check her
math!). ...the confusion may have come because powdered sugar
used to be sold in boxes by the pound. Many recipes would call
for a box or pound of confectioner's (powdered) sugar. So you
knew to use a half box or whole box...    added over 2 years ago
I would use 2.   Mrs. Larkin is a trusted source on Baking.
added over 2 years ago  Yep, my bag of confec. sugar says 1/4
cup = about 1 oz. So 2 cups = about a 1/2 pound of 10x.  If
you're not able to weigh it, fluff it up really well before
measuring it.  No need to email
