The Proper Way to Measure This Ingredient
Spoon brown sugar into the measuring cup and press down firmly with your fingers or a spoon until level. When inverted, it should hold the distinct shape of the cup.
Costly Recipe Defect
Warning: The Common Scooping Mistake
Scooping loosely without packing leaves large air voids, yielding only 170g to 180g (-20% deficit). Under-measuring brown sugar deprives cookies of the moisture required for a soft, bendable center, leaving them dry, brittle, and pale.

Tested Baking Substitutions (Exact Gram Ratios)
When replacing this ingredient, volumetric cup swaps fail. Use these kitchen-tested gram ratios to maintain correct moisture and rise.
Option 1
White Sugar + Molasses (Exact Replica)
Combine 200g of Granulated White Sugar with 20g (1 tbsp) of Dark Molasses; blend with a fork until uniform.
Produces an identical 220g batch of authentic fresh brown sugar with flawless moisture and flavor.
Option 2
Muscovado / Demerara Sugar
Substitute 1:1 by weight (220g Muscovado for 220g Brown Sugar).
Delivers a richer, unrefined toffee-molasses profile perfect for gingerbread, fruitcakes, and sticky toffee pudding.

Ingredient Chemistry & Weight FAQs
Packed Brown SugarSticky molasses creates surface tension and air pockets between crystals. Packing compresses these voids to standardize measurement at 220g per cup.
No. Both weigh 220 grams per firmly packed cup; dark brown sugar simply contains ~6.5% molasses versus ~3.5% in light brown sugar.
Microwave it in a bowl covered with a damp paper towel in 15-second bursts, or seal it with a slice of fresh bread overnight to restore moisture.
