The ratio for using stevia instead of granulated sugar is 1 tsp stevia per cup of sugar (follow the brand — strengths vary). Write it on a sticky note and keep it on the fridge, because it is the kind of number you will use again — but do not stop there. The reason this page is long is that a sweetener swap is never only about sweetness. It changes how fast the bake browns, how moist the crumb stays, how far a cookie spreads, and how long the finished cake keeps. Get those right and nobody will know you substituted; get them wrong and the bake tells on you.

Sweeteners differ in sweetness, moisture and browning; liquid sweeteners need the recipe's liquid reduced. That single sentence is the key to this swap. Everything below follows from it: the conversion table with the liquid adjustments, three worked examples, what changes in the result, and the recipes where this substitution should not be attempted.

The ratio, in a table

The table below converts granulated sugar to stevia for the amounts you are most likely to meet. The rule is always the same: 1 tsp stevia per cup of sugar (follow the brand — strengths vary).

Granulated sugar Stevia to use Notes
1/4 cup 1/4 teaspoon Follow the brand — strengths vary.
1/3 cup 1/3 teaspoon Follow the brand — strengths vary.
1/2 cup 1/2 teaspoon Follow the brand — strengths vary.
2/3 cup 2/3 teaspoon Follow the brand — strengths vary.
3/4 cup 3/4 teaspoon Follow the brand — strengths vary.
1 cup 1 teaspoon Follow the brand — strengths vary.
2 cups 2 teaspoons Follow the brand — strengths vary.

By weight, one cup of granulated sugar is about 198 g (King Arthur Baking, spooned and levelled). Our density table does not list a grams-per-cup figure for stevia, so no weight is given for it here — measure it by volume and, if the recipe is sensitive, weigh a trial cup yourself and note the number. All weights here are approximate; verify with a kitchen scale when the bake matters.

King Arthur lists 198 g per cup; USDA FoodData Central rounds granulated sugar to 200 g per cup. The 2 g difference is rounding, not a real disagreement.

Worked examples

Example 1: A batch of muffins

Muffins are a good middle ground: more forgiving than a sponge cake, less forgiving than shortbread. A recipe calls for 3/4 cup of granulated sugar. Using the ratio, that becomes 3/4 teaspoon. Mix the wet and dry ingredients separately, then combine with as few strokes as possible — the batter should look lumpy. Fill the cups two-thirds full and bake as usual. The muffins will have a slightly different crumb and may brown a little faster on top, so check them a few minutes early. If the tops brown too fast, cover the tin loosely with foil for the last few minutes.

Example 2: Brownies

Brownies are one of the easiest bakes to swap a sweetener in, because the chocolate does most of the work. A recipe calls for 1 1/2 cups of granulated sugar. Using the ratio, that becomes 1 1/2 teaspoons. Melt the butter and chocolate, stir in the sweetener and eggs, then fold in the flour. Bake as usual and check five minutes early. The brownies will be fudgy and rich, and the sweetener swap will be almost impossible to detect under the chocolate. If the swap adds a strong flavour of its own, brownies are the recipe where that flavour works best.

Example 3: Shortbread

Shortbread is a strict test, because it has only three ingredients and the sugar is one of them. A recipe calls for 1/2 cup of granulated sugar. Using the ratio, that becomes 1/2 teaspoon. Cream the butter and sweetener, then mix in the flour until the dough just comes together — do not overwork it, or the shortbread will be tough. Press the dough into the tin, prick it with a fork, and bake at a low oven until pale gold. Shortbread should be pale, not brown, so if your substitute browns faster, lower the oven by 25°F and watch it closely. The texture will be a little different, but a good shortbread is still a good shortbread.

What changes in the result

Sweetness is the obvious change, but it is not the most important one. Sweeteners differ in sweetness, moisture and browning; liquid sweeteners need the recipe's liquid reduced. What matters more in practice is what the sweetener does to the structure of the bake. Sugar is a tenderiser: it interferes with gluten formation and delays the setting of starch, which is what makes a cake tender rather than tough. A substitute that does not tenderise the same way will give you a tougher crumb; a substitute that holds more water will give you a softer one. Sugar also controls spread — in cookies, it melts and lets the dough spread before it sets — so a different sweetener can make cookies thicker or thinner than the recipe intends. And sugar is a preservative in jams and a structural ingredient in meringues and candy, which is why those recipes are listed below under 'when not to substitute'.

When not to substitute

Do not swap 1:1 in candy-making, meringues or jam, where sugar's exact chemistry matters. In practice that means: do not make this swap in candy-making, where sugar's exact boiling behaviour is the whole recipe; do not make it in meringues, where sugar stabilises the egg white foam and a substitute can make the meringue weep or collapse; and do not make it in jam or preserves, where sugar is the preservative and getting it wrong is a food-safety issue, not just a taste issue. Be cautious in shortbread and in any recipe where sugar is a large share of the weight. And if the recipe is for someone managing blood sugar, remember that a different sweetener is not automatically a safe one — check with the person, and do not present a swap as a health claim.

Practical guidance

If you do not have a scale, measure carefully and consistently: spoon dry sweeteners into the cup and level them off, pack brown sugar firmly, and measure liquid sweeteners in a jug at eye level. Do not guess at the liquid adjustment — it is the part of the swap people most often forget, and a quarter cup of extra liquid is the difference between a moist cake and a soggy one. Store the substitute in an airtight container; keep liquid sweeteners at room temperature so they pour easily, and keep dry sweeteners away from steam and damp, which makes them clump.

All conversions on this page are approximate. A kitchen scale is the most reliable tool you own: weigh the substitute, note the number that works for your recipe, and use it next time. If a bake matters — a birthday cake, a loaf for guests — test the swap first in a small, forgiving recipe before you commit to the important one.

Frequently asked questions

Is stevia sweeter than granulated sugar?

Sweeteners differ in sweetness, moisture and browning; liquid sweeteners need the recipe's liquid reduced. Sweetness is not the whole story, though: a sweetener can match sugar's sweetness and still change the bake, because sugar also controls moisture, browning, spread and texture. Judge the swap on the finished bake, not on a spoonful of the sweetener, and adjust the amount slightly next time if the result is too sweet or not sweet enough.

Will my cake brown more with stevia?

Possibly — and it depends on the sweetener. Liquid sweeteners and those with more fructose tend to brown faster, so a cake can look done before the centre is set. Check with a skewer rather than by colour, and if the top is browning too fast, cover the tin loosely with foil for the last part of the bake. If your substitute browns more slowly, the cake may look pale when it is ready — again, trust the skewer, not the colour.

Can I use stevia in cookies?

Yes, but expect the cookies to behave differently. Sugar controls spread: it melts in the oven and lets the dough spread before it sets. A substitute changes that balance, so the cookies may be thicker or thinner than the recipe intends. Chill the dough for 30 minutes and bake one test cookie first. If the cookies spread too much, chill the dough longer; if they stay too thick, flatten the balls slightly. The flavour difference will be small under the chocolate or spice.

Can I use stevia in meringue or candy?

No — not safely, and not with a good result. Meringue depends on sugar to stabilise the egg-white foam, and candy depends on sugar's exact boiling behaviour; a substitute changes both, and the result can be a weeping meringue or a candy that never sets. Jam is the same: sugar is the preservative, and getting it wrong is a food-safety issue. For those recipes, use the sugar the recipe calls for, or find a recipe written for the substitute from the start.

Will the texture change with stevia?

Yes, a little. Sugar tenderises crumb, controls spread and holds moisture, and every substitute shifts that balance. A liquid sweetener usually makes a moister, softer crumb; a dry substitute can make a drier one; a high-intensity sweetener adds sweetness without any of sugar's bulk, so the bake can be drier and less tender. The changes are small in a strongly flavoured bake and most noticeable in a plain cake or a cookie. If the texture matters, try the swap first in a forgiving recipe such as banana bread or brownies.

Can I use stevia in tea and coffee?

It depends on the sweetener. Dry sweeteners that dissolve well work in hot drinks; liquid sweeteners work too, though they add a flavour of their own. Sweeteners that do not dissolve — date sugar is the classic example — will sit at the bottom of the cup and are best kept for baking. High-intensity sweeteners need only a tiny amount in a drink, so measure carefully: a pinch too much can make a cup of tea unpleasantly sweet. Taste as you go.
