1 Cup Muscovado Sugar in Grams
1 cup of muscovado sugar weighs 213 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.
Muscovado sugar is an unrefined cane sugar with a high molasses content and a sticky, almost wet texture, and it is the darkest and most flavourful sugar in the pantry. A cup weighs 213 g when packed, the same as brown sugar, and it carries a deep flavour of liquorice, toffee and smoke that no other sugar can match. It is the sugar of gingerbread, sticky toffee pudding and dark marinades, where its flavour is the point of the dish. It hardens quickly when it is exposed to air, so it needs an airtight container, and a damp cloth or a slice of bread in the jar will soften a hardened block.
Why weighing muscovado sugar beats measuring it in cups
Sugar looks like the easiest ingredient to measure in cups, because the crystals pour cleanly and level neatly, but the weight per cup still varies a lot between types. A cup of granulated sugar weighs about 198 g, a cup of powdered sugar about 113 g, and a cup of packed brown sugar about 213 g, so swapping one sugar for another cup-for-cup changes the sweetness and the structure of a bake by a large margin. Sugar does more than sweeten: it holds moisture, tenderises crumb, feeds yeast, helps browning and sets the texture of everything from meringues to caramel. Getting the weight right is what keeps a cake moist instead of dry, a meringue crisp instead of weeping, and a jam setting instead of running. Because sugar dissolves, small errors are forgiving in drinks and sauces, but in baking they are not.

One tablespoon of muscovado sugar weighs about 13.3 g, and a cup is 16 tablespoons, so the tablespoon column is simply the cup weight divided by 16. 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. All the values in this table are approximate, and they assume the ingredient is measured packed, exactly as the source measured it.
How the weight was measured
The figure on this page comes from USDA, measured packed unless the method line says otherwise. Spooning means filling the cup with a spoon rather than plunging the cup into the bag, and levelling means sweeping a knife across the rim. Scooping packs the ingredient down and can add a fifth or more to the weight, which is why two bakers following the same cup-based recipe can get visibly different results. Confidence in this value is medium. That reflects how consistent the ingredient is from brand to brand: a uniform, factory-packed ingredient is more predictable than a fresh, variable one. Even a high-confidence figure is still an approximation, because moisture, grind size and settling all shift the weight a little. Treat the grams on this page as a reliable starting point and check with a scale when the recipe is fussy, expensive, or being made for the first time.
Worked examples
Sticky toffee pudding
A sticky toffee pudding that calls for 1 cup of muscovado sugar needs 213 g, packed firmly into the cup. The sugar gives the sponge its dark colour and its deep, almost burnt-caramel flavour, and it keeps the pudding moist for days. Pack the sugar firmly when you measure it, because loosely spooned muscovado weighs far less, and the pudding will be pale and under-sweetened if you under-measure it.
Gingerbread for the holidays
A gingerbread that uses 1 1/2 cups of muscovado sugar needs 319.5 g, melted with butter, golden syrup and spices before the flour is added. The molasses in the sugar is what makes gingerbread dark and sticky rather than pale and cakey, and it is also what keeps the biscuits soft for weeks in a tin. Weigh the sugar rather than scooping it, because the sticky crystals clump and a scooped cup is unreliable.
A dark marinade for barbecue
A barbecue marinade that calls for 1/4 cup of muscovado sugar needs 53.2 g, whisked with soy sauce, vinegar and spices. The sugar caramelises on the surface of the meat as it cooks, giving a dark, sticky glaze, and its molasses flavour stands up to smoke and chilli in a way that white sugar cannot. Dissolve it fully in the liquid before adding the meat, because undissolved crystals will burn on the grill.
When this conversion matters most
This conversion matters most in baking and preserving, where sugar controls structure as well as sweetness. In cakes it tenderises the crumb and holds moisture; in meringues it stabilises the foam; in jams it sets the pectin and preserves the fruit. It matters less in a cup of tea or coffee, where a gram or two either way is a matter of taste and you can adjust by sipping. It matters again when you scale recipes, because sugar errors multiply just like flour errors, and a doubled batch of cookies with too much sugar spreads thin and burns at the edges. When a recipe was developed by weight, matching that weight is the simplest way to match the result.
Common mistakes
The most common mistake is treating all sugars as interchangeable by volume. A cup of powdered sugar is nearly half the weight of a cup of granulated sugar, so a recipe that expects one and gets the other will be badly under- or over-sweetened. The second mistake is packing brown sugar when the recipe expects it spooned, or the reverse: packed brown sugar weighs about 213 g per cup while loosely spooned brown sugar weighs around 170 g, a difference of more than 40 g. The third is measuring sticky syrups in a dry cup and losing half of it on the sides; a light wipe of oil on the cup helps a syrup slide out cleanly. And the fourth is sifting powdered sugar before measuring it, which adds air and drops the weight per cup to around 100 g. Measure first, then sift.
What to do if you do not have a scale
If you do not have a scale, use a dry measuring cup and the method the figure on this page was measured with: spooned and levelled for free-flowing sugars, firmly packed for brown and muscovado sugars, and poured at eye level for syrups. For syrups, measure in a liquid jug at eye level and use a flexible spatula to scrape every last drop out. For powdered sugar, spoon it in lightly and level it, and do not press it down. These methods get you close, but sugar is cheap to weigh and expensive to get wrong in baking, so a scale is the better investment here than for almost any other ingredient.
Storing muscovado sugar
Airtight container; add a damp cloth or bread slice if it hardens. Keeping muscovado sugar properly stored matters for the conversion as well as for the flavour: an ingredient that has absorbed moisture from the air weighs more per cup than a dry one, and one that has dried out weighs less. Store it in an airtight container, away from heat and light, and measure it in the state the recipe expects, not straight from a damp or stale bag.
Frequently asked questions
What is the difference between muscovado sugar and brown sugar?
Muscovado sugar is unrefined and retains all of its molasses, while brown sugar is refined white sugar with molasses added back. Muscovado sugar is darker, stickier and more intensely flavoured, with notes of liquorice and smoke, while brown sugar is milder. A cup of each weighs the same when packed, 213 g, so they can be swapped by weight, but the flavour of the finished dish will be noticeably darker and richer with muscovado sugar.
How do I soften muscovado sugar that has gone hard?
Put a damp cloth or a slice of bread in the airtight container with the sugar and leave it overnight, and the moisture will soften the block. You can also warm it gently in the microwave for a few seconds at a time, breaking it up as you go. To stop it happening again, keep the sugar in an airtight container and use it within a few months, because every time the jar is opened the sugar dries out a little more.
Can I use cups instead of a scale for muscovado sugar?
Yes, but a scale is more accurate. If you measure muscovado sugar packed, exactly as the figure on this page was measured, a cup will be close to 213 g, within a few grams. The problem is that most people scoop rather than spoon, which can add 15 to 25 percent to the weight, and that error is enough to change a bake. For everyday cooking, cups are fine. For baking, where the ratio of ingredients decides the result, weigh it and check the number on the scale.
How many tablespoons are in a cup of muscovado sugar?
There are 16 tablespoons in a US cup, so a cup of muscovado sugar is 16 tablespoons, and one tablespoon weighs about 13.3 g. A teaspoon weighs about 4.4 g. Tablespoons are useful when a recipe calls for a small amount, but they carry the same packing problem as cups: a heaped tablespoon can weigh half as much again as a level one, so level every spoon with the back of a knife, and use a scale for small amounts when accuracy matters.
Does the weight change if I pack or sift muscovado sugar?
Packing matters a great deal for muscovado sugar. It is measured packed firmly, so a loosely spooned cup weighs far less than a packed cup, by tens of grams. Press the ingredient into the cup firmly with the back of a spoon, level the top, and do not leave air pockets. If a recipe expects it spooned and you pack it, or the reverse, the sweetness and the moisture of the finished dish will be wrong.
