How to Substitute Sugar: Which Replacement Keeps Which Job

A University of Georgia Extension handout on sweeteners makes the key point in one line: sugar cannot be fully replaced in many baked goods because it also provides browning, volume, tenderness, texture and structure. Sweetness is the easy part to copy. The other jobs decide whether a swap works, and each replacement keeps a different set of them. The ratios live in the sugar substitute guide; this article sorts the options by job and works through the arithmetic of liquid sweeteners.

What sugar does besides sweeten

• Aerates fat. Beaten with solid butter, sugar crystals cut tiny air pockets that leaven creamed cakes and cookies. Only a dry, crystalline sugar can do this.
• Holds water. Sugar attracts and keeps moisture, so sweet cakes stay soft for days while lean bread stales overnight.
• Tenderizes. By tying up water, sugar slows gluten development and delays the setting of egg proteins, which keeps a crumb soft rather than tough.
• Browns. Sugar caramelizes on its own and joins in browning reactions with protein, giving crust color and toasty flavor.
• Controls spread. In cookie dough, sugar dissolves as it heats and lets the dough flow, so the amount and type of sugar shape how flat and crisp a cookie bakes.
• Stabilizes foams and feeds yeast. Sugar beaten gradually into egg whites makes a glossy, steadier meringue, and yeast ferments it in sweet doughs.

Which replacement keeps which job

Replacement, per 1 cup sugar	Creams with butter	Moisture	Browning	Sweetness
Packed brown sugar, 1 cup	yes	more (molasses film)	darker	same
Coconut sugar, 1¼ cups	yes	dry, like sugar	darker, butterscotch notes	same, per King Arthur
Honey, ¾ cup	no	much more	fast	sweeter than sugar
Maple syrup, 1 cup	no	much more	slightly faster than sugar	about the same
Stevia or sucralose alone	no bulk	none	none from stevia	far sweeter

The two granular swaps keep every job, which is why the brown sugar guide and coconut sugar are the low-risk choices for cookies and creamed cakes. Syrups trade aeration for moisture and color; high-intensity sweeteners keep only sweetness. Date sugar is a special case: King Arthur notes that its plant fiber keeps it from melting or dissolving, so it suits toppings and dense bakes rather than creaming or caramel.

The arithmetic of honey and maple syrup

King Arthur’s weight chart gives the reason liquid sweeteners need adjustments. A cup of granulated sugar weighs 198 g. The ¾ cup of honey that replaces it weighs about 252 g (21 g per tablespoon), and a cup of maple syrup weighs 312 g. The extra weight is mostly water the recipe never planned for. The published fixes:

• Honey: ¾ cup per cup of sugar, ¼ cup less of the recipe’s other liquid, and ½ teaspoon baking soda per cup of honey, per both the Utah State and Mississippi State extension charts. King Arthur trims liquid by 3 to 4 tablespoons instead.
• Maple syrup: an equal volume, with 3 to 4 tablespoons less liquid (King Arthur).
• No liquid to cut: King Arthur adds 3 to 4 tablespoons of flour per cup of honey, or about 1 tablespoon per ¼ cup of maple syrup.
• Temperature: King Arthur advises against honey in recipes baked above 350°F, because it scorches.

Worked through on a muffin batter with 1 cup sugar and 1 cup milk, baked at 375°F: use ¾ cup honey, cut the milk to ¾ cup, add ½ teaspoon baking soda to the dry ingredients alongside the existing leavening, and bake at 350°F. The lower temperature lengthens the bake by a few minutes, so test with a skewer rather than the clock. The maple version uses 1 cup syrup, cuts the milk by 3 to 4 tablespoons, and can stay at 375°F, since King Arthur notes maple browns only slightly faster than sugar. The honey guide runs the same logic in reverse, adding ¼ cup liquid when granulated sugar replaces honey.

King Arthur’s own trials show what changes even when the numbers are right: muffins made with liquid sweeteners rose well with a slightly coarser crumb, oil-based cakes became more crumbly and very moist, soft maple cookies spread more, and crisp cookies stayed soft for a day or two. A creamed honey cake baked much darker, and King Arthur calls creaming with syrups risky.

Zero-calorie sweeteners and sugar alcohols

The Georgia handout draws the line clearly. High-intensity sweeteners work where sugar is mainly flavor: drinks, pie fillings, cheesecakes, sweet sauces, marinades and no-bake cookies. In cakes, cookies and yeast breads, quality often suffers. The reasons are in the table: none of them aerates fat, holds water or browns.

• Stevia is heat stable but, according to Texas A&M AgriLife’s Dinner Tonight program, does not caramelize, so bakes stay pale, and it is not suitable for meringues.
• Sucralose works in baking in its baking formulation, which adds low-calorie fillers for bulk; the packet form supplies sweetness and nothing else.
• Erythritol is granular and provides bulk, but a 2023 review in Nutrients puts it at about 70% as sweet as sucrose, with a mild cooling effect in the mouth. Pure erythritol used cup for cup gives a less sweet result. Blends sold for baking are formulated differently from one brand to the next, so follow the package conversion.
• Liquid noncaloric sweeteners convert at ⅛ teaspoon per teaspoon of sugar in the Mississippi State chart, or by the maker’s directions.

A practical starting point for baking: replace part of the sugar rather than all of it. The real sugar left in the batter still browns, holds moisture and creams, while the sweetener covers some of the sweetness. For simply using less sugar, the sugar guide gives the tolerated cut.

Common mistakes

• Creaming butter with honey or maple syrup. A liquid cannot cut air into fat, so the cake bakes dense and, in King Arthur’s honey trial, much darker.
• Baking a honey batter at 375°F or above. The outside scorches before the center sets.
• Leaving out the baking soda with honey. Its acidity is left unbalanced, and the crumb comes out tight with a sour edge.
• Swapping all the sugar for stevia in a cake. The result is small, pale and dry, because stevia supplies no bulk, browning or moisture.
• Treating pure erythritol as equally sweet. At about 70% of sugar’s sweetness, a cup-for-cup swap tastes underpowered.
• Using coconut sugar by the level cup. Its loose crystals deliver less sugar per cup; measure 1¼ cups or weigh it.
