Batch Scaling Around 350g Powdered / Confectioners' Sugar
| Batch Scale | Weight (g / oz) | US Cups & Spoons | Metric (mL) |
|---|---|---|---|
| Half Batch (0.5×) | 175g (6.17 oz) | 1 ⅓ cups + 2 tbsp | 345 mL |
| Standard (1×) | 350g (12.35 oz) | 2 ¾ cups + 2 tbsp + 2 tsp | 690 mL |
| 1.5× Batch | 525g (18.52 oz) | 4 ⅓ cups + 2 tsp | 1035.1 mL |
| Double Batch (2×) | 700g (24.69 oz) | 5 ¾ cups + 1 tbsp + 1 tsp | 1380.1 mL |
| Triple Batch (3×) | 1050g (37.04 oz) | 8 ¾ cups | 2070.1 mL |
Measuring 350g of Powdered / Confectioners' Sugar in the Kitchen
Because 1 US Customary Cup (236.6 mL) of powdered / confectioners' sugar weighs 120g when measured unsifted spooned, 350 Grams (350g) translates to 2.92 US cups (2 ¾ cups + 2 tbsp + 2 tsp). By contrast, using the sifted measure (100g/cup — a 20g per-cup shift), 350g occupies 3 ½ cups (3.50 cups).
Without a kitchen scale, measure 2 ¾ cups + 2 tbsp + 2 tsp (46.67 tablespoons total) using unsifted spooned technique. Spoon gently into the measuring cup and level flat. If your recipe calls for sifted powdered sugar, measure after sifting (100g/cup) or weigh directly.

Why does powdered sugar contain cornstarch? ▾
Commercial confectioners sugar contains about 3% cornstarch as an anti-caking agent to prevent the microscopic particles from clumping.
Why do recipes specify sifted versus unsifted powdered sugar? ▾
Sifted powdered sugar traps significant air, dropping cup weight from 120g down to 100g—a 20% reduction in sweetness.
