1/2 Cup Muscovado Sugar in Grams
1/2 cup of muscovado sugar weighs 106.5 g (packed, USDA). Unrefined cane sugar with a high molasses content and sticky texture. All the figures on this page are approximate conversions based on the USDA value, so when a recipe really matters, verify with a kitchen scale.
Unrefined cane sugar with a high molasses content and sticky texture. It is used for gingerbread, sticky toffee pudding, marinades and chutneys. That range of uses is part of why the conversion comes up so often: the same ingredient appears in everyday cooking and in precise baking, and the two situations demand different levels of accuracy. Knowing the weight of half a cup, rather than guessing from a measuring cup, keeps the result consistent no matter which recipe you are following.
Why weighing half a cup of muscovado sugar beats measuring it in cups
The reason bakers weigh muscovado sugar instead of scooping it is that sugar is not just a flavouring, it is a structural ingredient. Too little and a cake dries out and a meringue weeps; too much and cookies spread into lace and a sponge turns sticky. 1/2 cup of muscovado sugar weighs 106.5 g when measured packed, and that number is the same whether you are making a weekday traybake or a celebration cake. Using the scale also keeps your recipe notes honest: when a bake turns out perfectly, you can repeat it exactly, because grams do not change with the weather or the way you hold the cup.

| 3 cups | 639 g |
One tablespoon of muscovado sugar weighs about 13.5 g, and one teaspoon about 4.5 g. For small amounts a scale that reads to the gram is far more reliable than a spoon, because a heaped tablespoon can weigh half as much again as a level one. The table is rounded to the nearest half gram, so the numbers are approximate by design; the half-cup figure of 106.5 g is the one to use when a recipe calls for half a cup.
How the weight was measured
Packed means pressing the ingredient firmly into the measuring cup with the back of a spoon until it holds its shape when turned out. Loose spooning leaves air pockets and under-measures, so packing is part of the measurement, not a shortcut.
The source for the 213 g per cup figure is USDA, and the confidence in the value is medium. USDA publishes a standard ingredient weight chart that recipe developers use as a reference, and this page follows it exactly rather than averaging across sources, because an average of two different measuring methods is a number that matches nobody's cup.
Because muscovado sugar is measured packed, the weight per cup is stable from one kitchen to the next, and the 106.5 g figure for half a cup is a reliable default. Small differences in brand or temperature shift it by only a gram or two, which is far below the threshold that changes a recipe.
All the figures on this page are approximate conversions. When a recipe really matters, verify with a kitchen scale: weigh the ingredient directly into the bowl on a tared scale and trust that number over any cup.
Worked examples
A sponge cake that must rise
A sponge calling for 1/2 cup of muscovado sugar needs 106.5 g, and the sugar must be weighed precisely because it stabilises the whisked eggs that lift the cake. An extra spoonful weighs the foam down and the sponge sinks; a short measure leaves it pale and dry.
Doubling a traybake
Doubling a traybake that uses 1/2 cup of muscovado sugar means 1 cup, or 213 g. Write the gram weight on the recipe card and the doubled bake will taste identical to the original, which is the whole point of converting to grams in the first place.
A dusting or topping
A crumble topping or dusting that asks for 1/3 cup of muscovado sugar needs about 71 g. Small fractional amounts are where cup measures are least reliable, so the scale turns a fiddly measurement into a ten-second job.
When this conversion matters most
Precision matters most when you are repeating a success. A bake that turned out perfectly deserves to be repeatable, and grams are the only record that survives from one kitchen to the next. Record 106.5 g for 1/2 cup of muscovado sugar on your recipe card, and the next time you make it the result will be the same, whether the sugar is fresh from a new bag or the last of a softened, clumpy one.
Common mistakes with muscovado sugar
- Levelling with a finger. A fingertip is not straight and not level. Use the back of a knife to sweep the top of the cup flat, or weigh 106.5 g and skip the levelling altogether.
- Measuring over the mixing bowl. Spilling a little extra into the bowl is easy and invisible. Measure over the bag or the sink, or weigh directly into the bowl on a tared scale.
- Ignoring the dispute note. Some sugars have genuinely disputed weights, so check the method note on this page before choosing a figure. Consistency within one recipe matters more than which authority you follow.
- Storing sugar open. An open bag lets in moisture and clumps, which changes the weight per cup. Keep muscovado sugar in an airtight container so 106.5 g per half-cup stays true.
Storage and handling
Airtight container; add a damp cloth or bread slice if it hardens. Keeping muscovado sugar stored properly also keeps its weight per cup stable: an ingredient that has absorbed moisture from the air weighs more per cup than a dry one, so good storage is not just about freshness, it is about measurement accuracy too. If a container has been open for months in a humid kitchen, the first thing to do before a precise bake is to weigh the ingredient rather than trusting the cup.
Frequently asked questions
How many grams is 1/2 cup of muscovado sugar?
1/2 cup of muscovado sugar weighs 106.5 g, measured packed according to USDA. That is the figure to use when converting a recipe from cups to grams, and it is the value the conversion table on this page is built on.
How do I measure muscovado sugar without a scale?
Packed means pressing the ingredient firmly into the measuring cup with the back of a spoon until it holds its shape when turned out. Loose spooning leaves air pockets and under-measures, so packing is part of the measurement, not a shortcut. That gives the closest result to 106.5 g per half-cup, but it is still an estimate: the honest answer is that a scale is the only way to know the exact weight, and a basic digital kitchen scale costs less than a bag of good flour.
Why do different websites give different weights for muscovado sugar?
Because they measure different things and round differently. Some sources scoop, some spoon and level, some pack, and some round to the nearest 5 or 10 g. A source that packs will always report a heavier cup than a source that spoons and levels, and both can be correct about their own method. The fix is to pick one source and one method and stick with it for the whole recipe.
What is muscovado sugar used for?
Gingerbread, sticky toffee pudding, marinades and chutneys. Unrefined cane sugar with a high molasses content and sticky texture.
Can I use muscovado sugar and granulated sugar interchangeably by weight?
Only with care. Different sugars have different weights per cup and different flavours, so swapping by volume is unreliable. Swapping by weight is better, but a sugar with more molasses, like brown or muscovado, also adds moisture and acidity, which changes how the bake behaves. For a straight swap, match the weight and expect a slightly different flavour and colour.
How should I store muscovado sugar?
Airtight container; add a damp cloth or bread slice if it hardens. Good storage keeps the ingredient fresh and keeps its weight per cup consistent, because moisture absorbed from the air adds grams that the recipe did not ask for.
