A 1 lb bag of turbinado sugar holds about 2.5 cups. The arithmetic is simple: 1 lb is 454 g, and one cup of turbinado sugar weighs 180 g, so 454 divided by 180 is 2.5 cups. Turbinado sugar is a raw sugar — large, golden crystals with a light molasses coating — and it is lighter per cup than granulated sugar, because the large crystals do not pack together as tightly. It is sold in 1 lb bags because most cooks use it as a finishing sugar and a coffee sugar, in smaller amounts than granulated sugar.
Two point five cups is about five batches of crumble topping at half a cup each, or ten cups of coffee at a quarter cup each — though nobody measures coffee sugar by the cup. Turbinado sugar is used where its crunch and its caramel flavour matter: sprinkled on muffins and scones before baking, stirred into coffee, scattered over a crumble, or used to rim a cocktail glass. Knowing the bag holds 2.5 cups lets you plan: if a recipe uses half a cup for a topping, a bag covers five batches, and you will know when it is time to buy another bag. Turbinado sugar keeps indefinitely, so a 1 lb bag is a good buy even if you use it slowly.

| 1/4 bag | 0.62 cups (about 5/8 cup) | 114 g |
| 1/2 bag | 1.25 cups (about 1 1/4 cups) | 227 g |
| 3/4 bag | 1.88 cups (about 1 7/8 cups) | 340 g |
| Full bag | 2.50 cups (about 2 1/2 cups) | 454 g |
| Cups | Grams (approx.) |
|---|---|
| 1 cup | 180 g |
| 2 cups | 360 g |
| 3 cups | 540 g |
| 4 cups | 720 g |
| 5 cups | 900 g |
| 10 cups | 1,800 g |
Turbinado sugar is a raw sugar with large, golden crystals. It is lighter per cup than granulated sugar (180 g vs 198 g) because the large crystals do not pack as tightly.
Worked examples
A crumble topping for an apple crumble
An apple crumble for six people uses 1/2 cup of turbinado sugar in the topping, mixed with flour, oats and butter, then scattered over the apples and baked until golden. One 1 lb bag holds 2.5 cups, so it covers five crumbles. The large turbinado crystals do not dissolve fully in the oven, which gives the topping a crunchy texture and a caramel flavour that granulated sugar cannot match. Rub the butter into the flour and oats until the mixture resembles coarse breadcrumbs, stir in the turbinado sugar, and scatter it generously over the fruit.
Muffins with a crunchy top
A batch of twelve muffins uses 1/4 cup of turbinado sugar sprinkled over the tops before baking, which gives them a crunchy, caramelised crust. One 1 lb bag holds 2.5 cups, so it covers ten batches — 120 muffins. Sprinkle the sugar over the batter just before the muffins go in the oven, and do not press it down — the sugar will melt slightly and form a crisp shell as the muffins bake. The crunch is the point: a muffin with a turbinado top is a different experience from a plain muffin.
Sweetening coffee for a crowd
A brunch for ten people goes through about 1/4 cup of turbinado sugar in coffee, at a teaspoon or two per cup. One 1 lb bag holds 2.5 cups, so it covers ten brunches — months of coffee for most households. Turbinado sugar dissolves more slowly than granulated sugar, because the crystals are larger, so stir the coffee well and let it sit for a moment. The light molasses flavour is a pleasant change from plain sugar, and the golden colour looks good in a sugar bowl on the table.
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 turbinado sugar. 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 180 g per cup, spooned and levelled, sourced from King Arthur Baking.
Practical guidance
Turbinado sugar is a finishing sugar, not a general-purpose baking sugar — and understanding that distinction is the key to using it well. The large crystals do not dissolve easily, which is a disadvantage in a batter or a dough, where undissolved sugar makes a gritty texture, but an advantage on top of a muffin or a crumble, where the crystals stay intact and give a crunch. Do not use turbinado sugar in a cake batter or a cookie dough unless the recipe calls for it: the large crystals will not cream properly with butter, and the bake will be uneven. Use it where it shines — on top of things, in coffee, in a crumble topping, on a rim of a glass.
Measure turbinado sugar by weight when it matters. A cup weighs 180 g, but the exact weight depends on how you fill the cup — the large crystals leave air gaps, so a loosely filled cup weighs less than a firmly filled one. Weighing removes the variable: half a cup is 90 g, every time. Store turbinado sugar in an airtight container in a cool, dry place, and it will keep indefinitely — sugar does not go off. It absorbs moisture and clumps, like all sugars, so keep the bag sealed. If it has clumped, break the lumps up with a fork. Turbinado sugar is sometimes called raw sugar, and it is similar to demerara sugar — but demerara crystals are larger and the sugar is heavier per cup, at 220 g, so the two are not interchangeable by volume.
Frequently asked questions
Is turbinado sugar the same as demerara sugar?
No, though they are similar. Both are raw sugars with large crystals, but demerara crystals are larger and the sugar is heavier per cup — 220 g compared with 180 g for turbinado. They swap in a topping or in coffee, but not measure for measure by weight in a recipe that depends on the sugar amount.
Can I use turbinado sugar instead of granulated sugar?
In coffee and as a topping, yes. In a batter or a dough, no — the large crystals do not dissolve easily and will not cream properly with butter, which gives a gritty texture and an uneven bake. Use turbinado sugar where its crunch and caramel flavour matter, and granulated sugar where the sugar needs to dissolve.
How many cups are in a 2 lb bag of turbinado sugar?
About 5 cups. A 2 lb bag is 907 g, and at 180 g per cup that divides out to 5.04 cups. That is about ten crumble toppings at half a cup each, or twenty batches of muffins at a quarter cup each.
Is turbinado sugar healthier than white sugar?
Not meaningfully. Turbinado sugar is less refined than white sugar and retains a little molasses, which gives it a trace of minerals — but the amounts are so small that they make no nutritional difference. It is still sugar, and it should be used in the same amounts as any other sugar.
How long does turbinado sugar keep?
Indefinitely, in an airtight container in a cool, dry place. Sugar does not go off, but it absorbs moisture and clumps. If it has clumped, break the lumps up with a fork. Keep the bag sealed and dry, and a bag of turbinado sugar will last for years.
