1/4 Cup Demerara Sugar in Grams
1/4 cup of demerara sugar weighs 55 g (spooned and levelled, King Arthur Baking). Large-crystal golden cane sugar with a toffee note. All the figures on this page are approximate conversions based on the King Arthur Baking value of 220 g per cup, so when a recipe really matters, verify with a kitchen scale.
Why a quarter cup is worth weighing
A quarter cup is a small measure, and small measures are where cup errors hurt most. A 5 g mistake in a full cup of demerara sugar is a rounding error; the same 5 g on a quarter cup is a 17 percent swing on 55 g, and in a small batch that swing can change the result. Recipes that call for a quarter cup are usually small, precise or both — a mug cake, a glaze, a roux, a single-serve bake — and there is no large batch to absorb the error. Weighing 55 g takes five seconds and removes the problem entirely.
Spooned and levelled is the method behind the number, and it matters. Demerara Sugar is used for crumble toppings, shortbread and sweetening hot drinks. 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. Grams cut through all of that: 55 g of demerara sugar is 55 g whatever the brand, the humidity or the size of your measuring cup.
Demerara Sugar cups to grams conversion table
| Cups | Grams | Tablespoons |
|---|---|---|
| 1/4 cup | 55 g | 4 |
| 1/3 cup | 73.3 g | 5.3 |
| 1/2 cup | 110 g | 8 |
| 2/3 cup | 146.7 g | 10.7 |
| 3/4 cup | 165 g | 12 |
| 1 cup | 220 g | 16 |
| 1 1/2 cups | 330 g | 24 |
| 2 cups | 440 g | 32 |
The tablespoon column shows how many tablespoons each amount equals: a quarter cup is 4 tablespoons, and one tablespoon of demerara sugar weighs about 13.8 g. A cup is 16 tablespoons, so the numbers in the table are just the cup weight divided by 16, rounded to one decimal place. 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. Read the table from the 1/4-cup row outwards: every other row is a multiple of 55 g, so scaling a recipe up or down is simple multiplication.
How the weight was measured
Spooned and levelled means the ingredient is measured the way King Arthur Baking measures it: spooned and levelled. For demerara sugar, that gives 220 g per cup, and a quarter of that is 55 g. The source for the figure is King Arthur Baking, and the confidence in the value is high. King Arthur Baking 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.
There is no serious dispute about this figure: King Arthur Baking lists 220 g per cup, and other reputable charts agree within a gram or two. The variation that remains comes from how the ingredient is measured, not from disagreement about the number itself.
Worked examples
Sweetening a smoothie for two
A smoothie for two rarely needs added sugar at all, but if the fruit is sharp, 1/4 cup of demerara sugar — 55 g — is the most you would add, and usually half that is enough. Weighing it, even for a drink, shows how much sugar is actually going in: 55 g looks like a small pile in a cup, but it is a lot of sweetness once it dissolves into the blender.
A crumble topping for one ramekin
A single-serve crumble topping uses about 1/4 cup of demerara sugar rubbed with flour and butter — 55 g. The sugar is what makes the topping crisp and golden instead of pale and floury, and the ratio to the flour decides whether it crumbles or melts. Weigh 55 g alongside the flour, and the topping behaves the same way every time you make it.
A glaze for a loaf cake
A simple glaze for a loaf cake takes about 1/4 cup of demerara sugar whisked with a spoonful or two of liquid — 55 g in total. The glaze should pour in a slow ribbon and set to a thin, crackling shell. If the sugar is under-measured the glaze stays watery and slides off; over-measured and it sets thick and gritty. Weighing 55 g gives you the right starting point, and then you adjust the liquid by the teaspoon.
Sugar is hygroscopic
Sugar pulls moisture from the air, and demerara sugar is no exception. A bag left open in a humid kitchen weighs more per cup than a fresh bag, because some of that weight is water. Store it sealed, and if it has clumped, break it up before measuring — a clump in a quarter cup can throw the weight off by several grams and leave a hard lump in the finished bake.
Scaling a quarter cup up and down
Once you know that 1/4 cup of demerara sugar is 55 g, the rest is arithmetic. Half a cup is 110 g, three quarters is 165 g, and a full cup is 220 g. Doubling a recipe that calls for 1/4 cup means weighing 110 g; halving it means 27.5 g, which is 2 tablespoons. Writing the recipe in grams at this point is worth doing: the next time you make it, you weigh 55 g straight into the bowl and skip the measuring cup altogether. If you are scaling a recipe for a different tin size, convert every ingredient to grams first and then multiply — scaling by volume compounds the error on every ingredient at once, while scaling by weight keeps each one exact.
Common mistakes with demerara sugar
- Packing when the recipe says spooned. Brown sugar is packed, but demerara sugar is spooned and levelled. Packing a spooned sugar adds grams the recipe did not ask for.
- Measuring sticky sugar in a dry cup. Sticky sugars cling to the cup and leave some behind. Weigh 55 g straight into the bowl instead.
- Swapping sugars cup for cup. Different sugars weigh different amounts per cup — demerara sugar is 220 g per cup, and another sugar may be far lighter or heavier. Convert by weight, not by volume.
- Forgetting that sugar is also liquid. Liquid sugars like syrups and honey add moisture as well as sweetness. Swapping them for a dry sugar changes the batter, not just the taste.
Storage and handling
Airtight container, cool and dry, indefinitely. Keeping demerara 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 a sealed container is not just about freshness, it is about measurement accuracy too. If a bag 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. Label the container with the conversion — 1/4 cup is 55 g — and the next person to bake with it will thank you.
Frequently asked questions
How many grams is 1/4 cup of demerara sugar?
1/4 cup of demerara sugar weighs 55 g, measured spooned and levelled according to King Arthur Baking. That is one quarter of the full-cup weight of 220 g, and it is the figure to use when converting a recipe from cups to grams. All the figures on this page are approximate, so when a recipe really matters, verify with a kitchen scale.
Is 1/4 cup of demerara sugar always 55 g?
No — 55 g is the standard value from King Arthur Baking for demerara sugar measured spooned and levelled, and it is the right default. Brand, moisture, how settled the container is and how firmly it was packed can shift the weight by a few grams. For most cooking that variation does not matter. For precise baking, weigh the ingredient and trust the scale over the cup.
How do I measure 1/4 cup of demerara sugar without a scale?
Demerara Sugar is measured spooned and levelled, according to King Arthur Baking. Spooned and levelled it into a 1/4-cup measure, level the top with the back of a knife, and you will be close to 55 g. That is the best you can do without a scale — but be honest with yourself that it is an estimate. A basic digital kitchen scale costs less than a bag of good flour and removes the guesswork from every recipe, not just this one.
What is demerara sugar used for?
Crumble toppings, shortbread and sweetening hot drinks. Large-crystal golden cane sugar with a toffee note. A quarter cup — 55 g — is a common amount in small batches, glazes, sauces and test bakes, which is why this conversion comes up so often.
How should I store demerara sugar?
Airtight container, cool and dry, indefinitely. 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.
