How to Measure Small Amounts of Sweetener

Here's how to measure stevia without guessing: start with the sugar equivalent printed on your package, then measure the product itself by weight or with the scoop it came with. Care matters because the sweet compounds in stevia are 200 to 400 times sweeter than table sugar, according to the U.S. Food and Drug Administration (FDA), so a small slip changes the taste a lot.

Same spoon, very different weights. That's the whole challenge with sweeteners in one table.

Why sweeteners are tricky to measure

Most stevia products you buy aren't pure stevia. The sweet part is so concentrated that makers blend it with a bulking ingredient so you can spoon it. Some blends are designed to swap cup for cup with sugar. Others are much stronger and use tiny amounts. Pure extract powders and liquid drops are stronger still.

That means two bags that both say "stevia" can need very different amounts for the same sweetness. The only number you can trust is the one on your own package. Sucralose has the same issue. The FDA describes it as about 600 times sweeter than table sugar, and King Arthur Baking lists granulated Splenda at just 25 g per cup, compared with 198 g for granulated sugar.

How to measure stevia for a recipe

1. Find the conversion chart or sugar equivalent on your package. Many brands also post one on their website.
2. Work out how much of your sweetener replaces the sugar in your recipe, using that chart.
3. If the package gives a gram amount, tare your bowl or spoon and weigh to that number.
4. If it gives spoons or scoops, level them off with a flat edge. Don't pack or heap.
5. Write down what you used and how it tasted, so you can repeat it or adjust next time.

Very concentrated extracts are a special case. The amounts can be so small that a kitchen scale won't register them well, so the little scoop that comes in the jar is often the more practical tool. Follow the package on that.

Baking with sugar swaps

Sugar does more than sweeten. In baking it adds bulk, helps with browning and holds on to moisture. When you replace it with a sweetener that's much lighter in weight, the recipe can come out smaller, paler or drier. That's not a measuring error. It's chemistry.

The easy fix is to start with a recipe written for your sweetener, or follow the baking guidance on the package. Many brands give separate directions for drinks, sauces and baked goods. For coffee, tea, yogurt and oatmeal, swaps are much more forgiving, and weighing the same amount every time is all you need.

Common mistakes

• Switching brands without checking. A new bag can be stronger or weaker than your old one. Read the chart again.
• Using sugar's weight for a substitute. 12.4 g of sugar per tablespoon has nothing to do with what your sweetener weighs.
• Packing the spoon. Light, fluffy blends compress easily. A packed spoon holds more than the package expects.
• Adding more right away. Stir, wait a moment, taste, then adjust in small steps.

A practical tip: for small amounts of spoonable sweetener in drinks or batters, a MeasureMate digital measuring spoon scoops and weighs in one step and reads in 0.1 g steps. Press the tare button to zero the reading, scoop, and you'll see exactly how much is in the spoon instead of guessing from how full it looks.

Quick questions

How much stevia equals 1 teaspoon of sugar?

It depends on the product. Blends, pure extracts and drops all use different amounts, so check the sugar equivalent on your package.

Can I weigh pure stevia extract?

You can try, but the amounts are often too small for a kitchen scale to read well. Use the scoop that comes with the extract and follow its directions.

Is Splenda measured the same way as stevia?

No. Each sweetener has its own conversion chart. King Arthur Baking lists granulated Splenda at 25 g per cup, so even a full cup weighs very little.

Weights based on the King Arthur Baking ingredient weight chart and the U.S. Food and Drug Administration's guidance on sweeteners.
