A 1 lb bag of muscovado sugar holds about 2.1 cups — packed. Muscovado sugar is measured the same way as brown sugar: press it firmly into the cup measure until it holds its shape, because loosely spooned muscovado weighs far less. Packed, a cup of muscovado sugar weighs 213 g, and 454 divided by 213 is 2.1 cups. Muscovado is an unrefined sugar with a high molasses content, which gives it a dark colour, a moist, sticky texture, and a deep, almost liquorice-like flavour. It is the darkest and most flavourful of the brown sugars, and it is sold in 1 lb bags because most bakers use it in small amounts, for gingerbread, sticky toffee pudding and dark fruit cakes.
Two point one cups is about two sticky toffee puddings at 1 cup each, or four batches of gingerbread at half a cup each, or two dark fruit cakes at 1 cup each. Muscovado sugar is a specialist ingredient, and knowing the bag holds 2.1 cups — packed — lets you plan: if a recipe uses 1 cup, a bag covers two bakes, and you will know when it is time to buy another bag. Muscovado sugar dries out and hardens faster than any other sugar, because of its high moisture content, so buy the 1 lb bag rather than a larger one, and store it properly.
Bag of muscovado sugar conversion table
The table below shows how many cups you get from fractions of a 1 lb bag, and how many cups of muscovado sugar weigh how many grams. All figures use 213 g per cup, packed firmly.
| Amount | Cups (approx.) | Weight |
|---|---|---|
| 1/4 bag | 0.53 cups (about 1/2 cup) | 114 g |
| 1/2 bag | 1.05 cups | 227 g |
| 3/4 bag | 1.58 cups (about 1 5/8 cups) | 340 g |
| Full bag | 2.10 cups (about 2 1/8 cups) | 454 g |
| Cups | Grams (approx.) |
|---|---|
| 1 cup | 213 g |
| 2 cups | 426 g |
| 3 cups | 639 g |
| 4 cups | 852 g |
| 5 cups | 1,065 g |
| 10 cups | 2,130 g |
Muscovado sugar must be measured packed, like brown sugar. It weighs 213 g per cup packed, and it is the darkest and most flavourful of the brown sugars, with a high molasses content.
Worked examples
Sticky toffee pudding for eight
A sticky toffee pudding for eight people uses 1 cup of muscovado sugar — packed — in the sponge and the toffee sauce combined. One 1 lb bag holds 2.1 cups, so it covers two puddings with a little left over. The muscovado gives the pudding its deep, dark caramel flavour and its moist, sticky texture, which brown sugar alone cannot match. Measure the sugar packed for both the sponge and the sauce, because the recipe depends on the full amount. Serve the pudding warm with custard or ice cream, and pour the extra sauce over the top at the table.
Gingerbread for the holidays
A batch of gingerbread uses 1/2 cup of muscovado sugar — packed — mixed with molasses, butter, flour, ginger, cinnamon and cloves. One 1 lb bag holds 2.1 cups, so it covers four batches — enough for a house, a batch of men, and two trays of biscuits. Muscovado sugar makes gingerbread darker and more flavourful than brown sugar, with a deep molasses note that pairs well with the spices. Pack the sugar firmly into the cup, because a loosely measured half cup is noticeably less sugar, and the gingerbread will be less sweet and less dark.
A dark fruit cake for Christmas
A dark fruit cake uses 1 cup of muscovado sugar — packed — mixed with butter, eggs, flour, dried fruit, nuts and spices, then baked slowly for two hours. One 1 lb bag holds 2.1 cups, so it covers two cakes. The muscovado gives the cake its dark colour and its rich, almost liquorice-like flavour, which is the signature of a traditional Christmas cake. Soak the fruit in brandy or tea overnight before baking, and wrap the finished cake in baking paper and foil — it keeps for months, and the flavour improves with age.
How the figure is worked out
Think of the answer as a conversion, not a measurement. The package weight is a standard 1 lb (454 g) bag of muscovado sugar, packed. One cup of this ingredient weighs a known number of grams, so the cups in the package are the package weight divided by the cup weight. The method matters as much as the number: a spooned and levelled cup is the standard, and a scooped cup packs in more, which is why two bakers can get different cup counts from the same bag. The cup weight used here is 213 g per cup, packed, sourced from USDA.
Practical guidance
Muscovado sugar hardens faster than any other sugar, and that is the most important thing to know about it. The high molasses content makes it moist and sticky, and when that moisture evaporates, the sugar sets into a rock-hard block. Store muscovado sugar in an airtight container, and put a piece of bread or a terracotta sugar saver in the container — the bread gives up its moisture to the sugar and keeps it soft. If your muscovado has already hardened, put it in a bowl with a damp paper towel, cover it with cling film, and microwave it for twenty seconds — the steam will soften it. Or put a slice of bread in the bag overnight, and the sugar will be soft by morning.
Measure muscovado sugar packed, always — the same as brown sugar. Press it firmly into the cup measure with the back of a spoon, level it off, and turn it out: it should hold its shape. Packed, a cup weighs 213 g, the same as brown sugar, because muscovado is essentially a dark, unrefined brown sugar. Loosely spooned, it weighs far less, and the recipe will be short on sugar. Weighing is even better: 1 cup packed is 213 g, every time. Muscovado sugar is not the same as brown sugar — it is darker, moister and more strongly flavoured — but it swaps one-to-one for dark brown sugar in most recipes, and it is the better choice when you want a deep, dark flavour, as in gingerbread, sticky toffee pudding and Christmas cake.
Frequently asked questions
What is the difference between muscovado and brown sugar?
Muscovado is an unrefined sugar with a high molasses content, which makes it darker, moister and more strongly flavoured than brown sugar. Brown sugar is refined sugar with molasses added back. They weigh the same per cup packed — 213 g — so they swap measure for measure, but muscovado gives a deeper, darker flavour.
How do I soften hard muscovado sugar?
Put it in a bowl with a damp paper towel, cover it with cling film, and microwave it for twenty seconds. Or put a slice of bread in the bag overnight — the bread gives up its moisture to the sugar and softens it by morning. To prevent hardening, store muscovado in an airtight container with a piece of bread or a terracotta sugar saver.
How many cups are in a 2 lb bag of muscovado sugar?
About 4.3 cups packed. A 2 lb bag is 907 g, and at 213 g per cup that divides out to 4.26 cups. That is about four sticky toffee puddings at 1 cup each, or eight batches of gingerbread at half a cup each.
Can I use muscovado sugar instead of brown sugar?
Yes, measure for measure, packed. Muscovado is darker and more strongly flavoured, so the bake will be darker and richer. In gingerbread, sticky toffee pudding and fruit cake, muscovado is the better choice. In a light cookie or a delicate cake, brown sugar is better, because muscovado can overwhelm the other flavours.
How long does muscovado sugar keep?
Indefinitely, if it is kept soft and sealed — sugar does not go off. But muscovado hardens as it dries out, and once it is rock hard it is difficult to use. Store it in an airtight container with a piece of bread or a terracotta saver, and it will stay soft for months.
