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.
150g of powdered sugar is about 1 1/4 cups using Spoon & Level. For consistency, stick to one measuring method across the whole recipe.
Why Cup-to-Grams Accuracy Matters for Powdered Sugar
Small cup changes create big weight differences. For powdered sugar, 1 1/4 cups is about 150g, but just 1/4 cup more jumps to 180g.
This is why cup-based recipes can drift: packed, loose, or sifted volume can shift your actual grams. Using grams keeps hydration and texture consistent across batches.

If your recipe starts in cups, convert once to grams and bake by weight. That avoids hidden volume error and makes your result repeatable every time.
