How to reduce sugar in yeast bread: a simple fix

You’ve decided to cut back on the sugar in your diet. But you love to bake. It’s the baker’s conundrum! Thankfully, if you’re a bread baker, it’s easier to reduce sugar in yeast bread than in almost any other type of treat.

Cookies with a lower amount of sugar won’t spread properly. Reduced-sugar cakes may not rise as high. But sugar doesn’t affect the structure of yeast bread, except in a positive way: the lower the amount of sugar, the stronger a loaf’s rise.

And as for texture, reduced-sugar cakes or muffins may be tough and rubbery; and cookies tend to crumble. But when you reduce sugar in yeast bread, the only textural difference you might see is a tendency towards dryness.

Why is this? Sugar is hygroscopic; that means it attracts and holds moisture. Without sugar, moisture evaporates from bread during baking, creating a drier loaf. The more sugar you cut from a sweet yeast bread recipe, the more you’ll notice this effect. But omit the 2 tablespoons of sugar in your sandwich bread recipe, and the change in moisture level is subtle at most.

How about keeping qualities: does bread with sugar stay fresh longer? Yes, to a degree. A typical sandwich loaf with 1 to 2 tablespoons sugar starts out slightly softer than bread without sugar and remains that way as the days pass. But at this level of sweetening, the difference isn’t dramatic.*

*The best way to keep sandwich bread fresh? Decide how much you’ll use up within a couple of days, and store it at room temperature. Slice the remainder of the loaf, wrap individual packets of slices (I wrap five at a time), place in a bread bag, and freeze.

Bottom line: When you reduce sugar in yeast bread, the result is nearly all about flavor. The amount of sugar you use in yeast bread is strictly up to you and your taste buds.

Now, consider the sugar in breads and rolls whose flavor hallmark is sweetness. Will you be happy removing 100% of the sugar from a frosted cinnamon roll recipe, for instance?

No, probably not (though you can certainly reduce the sugar to a degree). You need to use common sense when looking at your recipe. Is sugar a major part of the experience (as in that beloved cinnamon roll)? Or is it secondary? (Think whole wheat bread.) How can you tell ahead of time?

Baker’s percentage can guide how you reduce sugar in yeast bread

Sweetness is subjective; people perceive sugar levels in very different ways. That said, you can use baker’s percentage (the weight of any ingredient in a recipe compared to the weight of the recipe’s flour) to gauge ahead of time just how sweet your bread might taste — and therefore how much sugar you’re willing to cut.

After some experimentation, I’ve decided a baker’s percentage of 10% sugar is the cutoff for sugar being a bit player instead of a star. Our Classic Sandwich Bread recipe, for example, calls for 2 tablespoons (25g) sugar and 3 cups (361g) flour. Let’s do the math: 25 ÷ 361 = 7%. When I sample this sandwich bread, my overall perception is simply “This tastes good;” not “This tastes sweet.”

Jump over to Portuguese Sweet Bread, however, and the story changes. With 1/3 cup (67g) sugar and 3 1/4 cups (390g) flour, the baker’s percentage of sugar is 17%. And when I sample a slice, my first impression is “This is sweet bread.”

How do you know how much sugar you can take out of that sweet bread recipe, and still perceive it as sweet? Don’t go below 10% baker’s percentage.

OK, enough with the math and science. Want to hear the 10 things I learned while testing how to reduce sugar in yeast bread? Thought so!

1. The best way to reduce sugar in yeast bread? Start with a recipe that doesn’t use any.

Some bread recipes use no sugar at all: think baguettes. If you’re determined to bake bread using no sugar at all, choose a sugar-free recipe: it’s as simple as that.

2. Many breads use barely any sugar.

Let’s go back to that sandwich loaf, with 2 tablespoons of sugar. Once you slice it up, you’ll be getting about 1/3 teaspoon sugar in each serving. Worth cutting? Up to you.

3. Yeast doesn’t need sugar to grow.

Actually, it does; but it doesn’t need you to spoon-feed it from your sugar bowl. Yeast readily makes its own food supply by transforming flour’s starch into sugar. Yes, sugar jump-starts yeast right at the beginning, but yeast dough without sugar will soon catch up.

4. If you’re unsure if your yeast is good, test it with sugar.

Most older recipes call for “proofing” active dry yeast by mixing it with sugar and water. Bubbles, foam, and expansion after 10 minutes or so mean the yeast is good. If you question whether the yeast in that old packet you found is alive, “prove” it by mixing it with 1/4 teaspoon sugar and 1/4 cup warm water.

5. The more sugar in yeast dough, the more slowly it will rise.

Remember, sugar is hygroscopic. And in yeast dough, this means it can deprive yeast of the moisture it needs to grow. Ever waited impatiently for your sweet bread to rise? Blame the “arid” atmosphere; and change your yeast (see #6, below).

6. Special yeast helps high-sugar breads rise more quickly.

SAF Gold yeast is osmotolerant. Translation? It’s like a camel in the desert: it functions just fine with a limited amount of moisture. Use SAF Gold yeast in any recipe with more than 10% sugar (baker’s percentage), and you’ll see a faster rise.

7. A touch of sugar enhances flavor.

A small amount of sugar (like salt) enhances bread’s flavor. I’ve found anything up to 10% sugar (baker’s percentage) adds a certain richness to bread’s flavor without adding noticeable sweetness.

8. Sugar enhances browning — for better or worse.

Some of the sugar in yeast dough rises to the surface and caramelizes as bread bakes, yielding rich brown color. This may or may not be a good thing, though. The small amount of sugar in a sandwich loaf yields a nicely browned loaf. But the larger amount of sugar in panettone means you’ll need to tent it with foil as it bakes, to protect it from over-browning.

9. Bread with added sweet ingredients doesn’t require super-sweet dough.

If you’re making yeast bread with a good amount of dried fruit, chopped chocolate, or other sweet ingredients, cutting the amount of sugar in the dough is a no-brainer, taste-wise. Your tongue will focus on the sweet raisins and cherries, not the sugar-free bread surrounding them.

10. Think of sugar as a condiment, not the main dish.

Pure sugar on the tongue in the form of frosting or filling is perceived as much sweeter than any sugar in the bread itself. Lower the sugar in cinnamon rolls and sticky buns by first omitting some of the sugar from the dough.

Then, look at the filling and frosting. Again, look at your specific recipe: is there so much frosting that it’s mounded atop the rolls? So much brown sugar filling that it’s spilling out? Maybe a bit less of each will still provide the decadent rolls you want.

How to reduce sugar in yeast bread via @kingarthurflour

Here’s a tip: if you reduce the amount of frosting, stir in more liquid than you’d usually use. The more fluid your frosting, the easier it is to spread, the less you’ll use. Ditto the filling: if you use just plain brown sugar and cinnamon, add a bit of water to mix them into a slurry and paint it onto the dough before rolling and cutting.

Are you baking at altitude?

Remember, your yeast bread dough will rise more quickly anyway, so you may not need special yeast to help high-sugar breads rise.

Are you baking gluten-free?

These tips on reducing sugar in yeast bread apply equally well to those of you baking without gluten.

    Hi PJ,

    What does the reduced-sugar, rapid rise do to flavor? You explained it will make it less sweet but we’ve been taught rise time equals flavor.


    1. PJ Hamel, post author

      Aaron, a longer rise doesn’t promote sweetness in yeast bread; rather, it enriches flavor with the addition of a slight tang from acetic acid, and the enhancing qualities of alcohol and organic acids (which I like to think of as promoting a kind of umami flavor). But if you’re talking about a sweet yeast bread, a shorter rise is generally fine, as you want toe main flavor to be sweet, not savory. Hope this helps — PJH

    Wow what a great article. There are may things that bakers do that we don’t know why we do them. We find out by trial and error.The information that you provide fills in the they how and why. I love these articles. Not only do these type of articles encourage me to try new things, give me confidence and produce great food, but make it great fun.

    I am diabetic on an insulin pump. When it comes to bread and other baked goods the only way I know to help you control your blood glucose is portion control. I eat bread 2 times a day. I have learned to slice very thin slices. I also agree that the best advise is consult with your doctor, diabetic educator and dietitian.


    Very interesting read, thanks, my biggest concern as a diabetic is that eating bread at all is a hefty dose of carbs which by any other name is sugar so debating the use of a couple of tablespoons of sugar in any recipe with carbs in is a bit redundant…got any recipes for low carb bread?

    I have noticed Truvia packaged for baking in the grocery store. I have not had the guts to try baking with this stuff yet. Have you used the Truvia in your baking?
    If yes, your opinion As to it’s taste and texture.
    Thank you

    1. The Baker's Hotline

      We don’t typically test with sugar substitutes ourselves, David, so we can’t offer much in the way of an opinion here. Maybe some of our other readers have experimented with this product and would be willing to share their thoughts? Mollie@KAF


      Try xylitol it’s natural and can be use like sugar…good for teeth…Google it, it sounds chemical but it’s not

  5. Chuck Heger

    Hi PJ,
    I bake simple white bread every week for toast to help the morning pills. But having a rather busy schedule, I use a bread machine. I’m intrigued to try it without the sugar (typically 2T). But before trying this and then having to start over from a disastrous result I thought I would ask you about this. I have always been under the assumption that the yeast needed ‘food’. But maybe not! So, should I give it a go deleting the sugar? BTW, I also bake traditional bread (and other goodies) when I have the time. I find it a very therapeutic exercise.

    1. PJ Hamel, post author

      Chuck, you can absolutely leave out the sugar; yeast doesn’t need it. That said, without any sugar your bread won’t brown quite as well, and probably won’t taste quite as good; sugar is a flavor enhancer, just like salt. Good to try it and see how you like it, though. More therapy, right? 🙂 PJH

    I did not know the amount of sugars in bread reading your article i learn the rule of thump since i have a family with diabetic

    Thank you

    When freezing any kind of bread or rolls, wrap it in paper towel before putting it in the freezer bag. We usually portion out 4 slices of bread or 2 or 4 rolls, wrap in paper towel and put it in a freezer bag. When the bag is defrosted, the product is just as fresh as when baked (or purchased), This is especially helpful (and economical) for 2 persons or 1 person households.

  8. AlanBD

    I was intrigued enough by the headline to read the article and (I’m from the UK) am amased that anyone would consider adding sugar to a bread dough.

  9. Suzan

    Thank you for the great tips on reducing sugar!

    I was wondering how sugar substitutes or the Splenda blends that are partially sugar plus substitute would work in breads, sweet rolls, cakes, cookies or muffins?

    1. The Baker's Hotline

      Suzan, we don’t do much experimenting with sugar substitutes like Splenda, so we recommend checking the manufacturer’s recommendations for substitutions. You might also consider doing some experimentation of your own to see how different sweeteners affect the final product. Mollie@KAF

  10. Jeff Poulsen

    Some bread recipes utilize molasses, honey, or maple syrup for the sugar. Do these ingredients behave the same as plain white sugar? Their tastes are nicer than white sugar.

    1. PJ Hamel, post author

      Jeff, sugar is sugar as far as yeast is concerned. So go ahead and try substituting your favorite liquid sweeteners (I like maple syrup). You may have to adjust the amount of liquid in the recipe; and honey does make bread brown more quickly. But other than that, you shouldn’t see any significant difference. PJH
