One cup of vanilla extract weighs 224 grams when poured, according to King Arthur Baking. That is the number to use whenever a recipe written in grams asks for vanilla extract by weight, or when you are scaling a recipe and need to know exactly how much of that small, dark, fragrant bottle you are actually adding. A single teaspoon — the amount most recipes call for — weighs about 4.7 grams, and a tablespoon weighs about 14 grams. These are approximate figures, because vanilla extract is a liquid and its density varies slightly by brand and alcohol content, but 224 grams per cup is the reliable reference value, and you should verify with a kitchen scale whenever the amount matters to the outcome.

Vanilla extract is one of those ingredients that punches far above its weight. It is used in teaspoons, not cups, in almost every recipe, yet it shapes the flavour of cakes, cookies, custards, ice creams and frostings more than almost anything else in the bowl. Understanding its weight matters less for a single batch of chocolate chip cookies — a teaspoon more or less will not ruin them — and much more when you are scaling recipes up for a bakery, converting an American recipe to grams for a European kitchen, or costing out a commercial batch where vanilla is the single most expensive ingredient by volume. A litre of good pure vanilla extract can cost more than many bottles of wine, so knowing that a cup is 224 grams helps you price a recipe accurately and avoid pouring money down the drain.

How much does vanilla extract weigh?

The table below gives the weight of vanilla extract for the amounts you are most likely to meet, from a single teaspoon up to four cups. All figures are derived from the King Arthur Baking value of 224 grams per cup, poured. Because vanilla extract is a liquid, the weight scales exactly with volume: half a cup is exactly half the weight of a full cup.

Amount Weight (grams) Weight (ounces)
1 teaspoon 4.7 g 0.17 oz
1 tablespoon 14 g 0.49 oz
1/4 cup 56 g 1.98 oz
1/3 cup 75 g 2.64 oz
1/2 cup 112 g 3.95 oz
2/3 cup 149 g 5.26 oz
3/4 cup 168 g 5.93 oz
1 cup 224 g 7.90 oz
1 1/2 cups 336 g 11.85 oz
2 cups 448 g 15.80 oz
3 cups 672 g 23.71 oz
4 cups 896 g 31.61 oz

A useful way to remember this is that vanilla extract is slightly lighter than water. One cup of water weighs 237 grams, while one cup of vanilla extract weighs 224 grams. The difference comes from the alcohol in the extract — pure vanilla extract is roughly 35% alcohol by volume, and alcohol is lighter than water. That is also why vanilla extract smells so strong the moment you open the bottle: the alcohol carries the volatile vanilla compounds straight into the air.

For everyday baking, the teaspoon and tablespoon rows are the ones that matter. Most cake recipes call for 1 to 2 teaspoons of vanilla extract, which is roughly 5 to 9 grams. Most cookie recipes call for 1 teaspoon per batch. If you are weighing ingredients, place your bowl on the scale, tare it to zero, and pour the vanilla in slowly until the scale reads the weight you need. It is faster and more accurate than hunting for a clean measuring spoon, and it saves washing up.

Worked examples

Example 1: Scaling a vanilla cake for a wedding

A bakery cake recipe calls for 2 tablespoons of vanilla extract per 9-inch layer, and you are making a three-tier wedding cake with four layers in total. That is 8 tablespoons of vanilla extract. At 14 grams per tablespoon, you need 112 grams — exactly half a cup. Weighing it out rather than counting spoonfuls matters here, because vanilla extract is the most expensive ingredient in the recipe and because a miscount of a tablespoon changes the flavour balance of a delicate vanilla sponge. Put a small jug on the scale, tare it, and pour until it reads 112 grams. If you are buying vanilla in bulk, this also tells you that a 500 ml bottle (about 2.1 cups) holds roughly 470 grams of extract, enough for about 34 tablespoons.

Example 2: Converting an American cookie recipe to grams

You find an American recipe for snickerdoodles that calls for 1 tablespoon of vanilla extract, and you are writing it out in grams for a friend in London who bakes by weight. One tablespoon is 14 grams. While you are at it, the recipe's 1 teaspoon of vanilla in the icing is 4.7 grams, which you would round to 5 grams on a kitchen scale. Small amounts like this are where weighing shows its limits: most home scales are only accurate to 1 gram, so 4.7 grams will read as 5 grams, which is fine. The rounding error is far smaller than the variation between one person's "teaspoon" and another's.

Example 3: Costing a batch of vanilla ice cream

A small ice-cream maker sells vanilla bean ice cream and uses pure vanilla extract in the base: 3 tablespoons per litre of base, and a production run is 20 litres. That is 60 tablespoons, or 840 grams — nearly 4 cups — of extract per run. At the price of good pure vanilla, that is a serious cost line, and it is exactly why the maker weighs the extract rather than pouring it freehand. Freehand pouring from a large bottle routinely overshoots by 10 to 20 percent, which on an 840-gram requirement is 84 to 168 grams of wasted extract per run. Weighing pays for the scale within a week.

Method and source

The figure of 224 grams per cup comes from King Arthur Baking's ingredient weight chart, and it is measured poured — vanilla extract is a liquid, so there is no spooning, levelling or packing involved. You simply pour it into a measuring jug at eye level and read the meniscus, or pour it onto a scale. King Arthur lists the value with high confidence, and it agrees closely with the density you would expect from a 35% alcohol solution carrying vanilla bean solids.

There is no serious dispute about this figure, unlike flour or sugar. Some sources round vanilla extract to 227 grams per cup (8 ounces by weight, the old imperial shortcut), and some round it to 220 grams. The difference between 224 and 227 grams is about 1.3 percent — irrelevant in a teaspoon, and barely noticeable even in a full cup. The figure to avoid is the one that treats vanilla extract as if it weighed the same as water (237 grams per cup). It does not; the alcohol makes it lighter, and using the water figure would overstate the weight by 13 grams per cup.

One important distinction: this page is about pure vanilla extract, the dark liquid made by steeping vanilla beans in alcohol and water. Imitation vanilla flavouring, which is usually vanillin dissolved in a propylene glycol or water base, has a slightly different density, and vanilla paste — a thick syrup with visible vanilla seeds — is denser still, at roughly 300 grams or more per cup depending on the brand. Do not use the 224-gram figure for paste or for imitation flavouring. If a recipe calls for vanilla paste, weigh it separately or follow the manufacturer's conversion, which is usually printed on the jar.

Practical guidance

Vanilla extract is almost always added to the wet ingredients — creamed with the butter and sugar, or whisked into the eggs and milk — because the fat and liquid distribute its flavour evenly through the batter. Adding it at the end, after the flour is in, risks pockets of strong vanilla flavour and streaks in a pale cake. In custards and ice cream bases, it is usually stirred in after cooking, off the heat, because prolonged boiling drives off the volatile aromatic compounds that make vanilla taste like vanilla. The alcohol evaporates during baking in any case, which is why vanilla extract is safe for children despite its alcohol content: the flavour stays, the alcohol does not.

The most common mistake with vanilla extract is using too little of a weak product or too much of a strong one. Cheap imitation vanilla needs roughly double the amount of pure extract to register, while a very concentrated double-strength extract needs only half. If you switch brands, taste the batter — a tiny dab on your tongue tells you more than any conversion table. The second most common mistake is storing it badly. Vanilla extract keeps for up to four years in a cool, dark cupboard, but it degrades in sunlight and heat. Keep the bottle tightly closed, away from the stove, and never store it in the fridge, where the cold can cause the vanilla compounds to cloud and separate. A bottle that smells flat, woody or chemical rather than warm and floral has passed its best and should be replaced.

If you do not have a scale, measuring vanilla extract by volume is perfectly fine — it is a liquid, and measuring jugs and spoons were designed for exactly this. Use a proper measuring spoon rather than a cutlery teaspoon, which can hold anywhere from 3 to 7 ml, and read a measuring jug at eye level. If you are out of vanilla extract entirely, the usual substitutes are vanilla paste (use the same amount), vanilla powder (use half the amount), or a scraped vanilla bean (one bean replaces about 1 tablespoon of extract). Almond extract is not a substitute — it is a different flavour altogether, and a teaspoon of it will overpower a cake.

Frequently asked questions

How many grams is 1 teaspoon of vanilla extract?

One teaspoon of vanilla extract weighs about 4.7 grams. On a home kitchen scale that reads to the nearest gram, that will show as 5 grams. Most recipes use 1 to 2 teaspoons, which is roughly 5 to 9 grams. For amounts this small, measuring by volume with a proper measuring spoon is just as accurate as weighing, and often easier.

How many grams is 1 tablespoon of vanilla extract?

One tablespoon of vanilla extract weighs about 14 grams. That is the figure to use when converting a recipe to grams: 2 tablespoons is 28 grams, and 3 tablespoons is 42 grams. A tablespoon is 15 ml, and vanilla extract is slightly lighter than water, which is why 15 ml weighs 14 grams rather than 15.

Is vanilla extract heavier or lighter than water?

Vanilla extract is lighter than water. One cup of vanilla extract weighs 224 grams, while one cup of water weighs 237 grams. The difference is the alcohol: pure vanilla extract is about 35% alcohol by volume, and alcohol is less dense than water. The difference is small — about 5 percent — but it matters when you are converting large volumes or costing a commercial recipe.

Can I use imitation vanilla instead of pure vanilla extract?

Yes, but expect a different result. Imitation vanilla is usually synthetic vanillin, which gives a simpler, flatter vanilla flavour without the hundreds of supporting compounds in real vanilla beans. In strongly flavoured recipes like chocolate cake it barely matters; in a vanilla sponge, panna cotta or ice cream, where vanilla is the star, the difference is obvious. If you do substitute, use the same amount by volume, but taste and adjust — some imitation products are weaker and need more.

Does vanilla extract go bad?

Pure vanilla extract does not really go bad in the way milk does, because the alcohol acts as a preservative. It does lose strength over time, especially if stored in light or heat. A bottle kept in a cool, dark cupboard stays good for up to four years. If it smells flat, woody or chemical instead of warm and sweet, it has faded and should be replaced. Never refrigerate it, and always keep the cap on tightly.

How much vanilla extract should I use in a cake?

Most cake recipes use 1 to 2 teaspoons (5 to 9 grams) of vanilla extract per batch. A good rule is 1 teaspoon per 250 grams of flour in the recipe. Using more will not make the cake taste more vanilla — it will make it taste bitter and alcoholic, because the excess volatile compounds have nowhere to go. If you want a stronger vanilla flavour, use a vanilla bean or vanilla paste alongside the extract rather than doubling the extract.
