5 Best Powdered Sugar Substitutes for Scones

Quick tip: Blend granulated sugar with cornstarch in a blender or food processor until very fine to replicate powdered sugar texture.

Powdered sugar is essentially granulated sugar ground to a fine powder with a small amount of cornstarch to prevent clumping. By blending granulated sugar with cornstarch, you recreate the fine texture and anti-caking properties that help distribute sweetness evenly in scone dough without affecting moisture content.

For best results, pulse the mixture until it reaches a powdery consistency, then sift before adding to the dough to avoid lumps. This substitute ensures the sugar integrates smoothly, preserving the scone's tender crumb.

Compared to store-bought powdered sugar, this homemade blend performs nearly identically, maintaining the scone's light texture and balanced sweetness.

Quick tip: Caster sugar dissolves more readily than granulated sugar but lacks the powdery texture, which may slightly affect dough consistency.

Caster sugar has smaller crystals than granulated sugar, allowing it to dissolve more quickly and evenly in dough. This helps maintain sweetness distribution in scones without adding moisture.

When substituting, ensure thorough mixing to prevent graininess. It’s best used when the dough is slightly wet or rested to allow sugar to dissolve.

While caster sugar won’t replicate the powdery texture perfectly, it preserves the scone’s crumb and sweetness better than coarse sugars.

Quick tip: Maple sugar adds a subtle maple flavor and is dry and fine but may slightly darken the dough color.

Maple sugar is made by dehydrating maple syrup into granules that are fine and dry, allowing it to substitute for powdered sugar without adding moisture.

It works well in scones by providing sweetness and a complementary flavor note, although it may alter the traditional taste slightly.

Use maple sugar when a hint of maple flavor is desired; it maintains the texture but changes the flavor profile compared to neutral powdered sugar.

Quick tip: Erythritol is a sugar alcohol with a similar crystalline structure but can have a cooling effect and less sweetness.

Powdered erythritol is ground to a fine powder like powdered sugar and can be used as a low-calorie sweetener in scones.

It dissolves well and maintains dough texture but may impart a cooling sensation on the palate and is less sweet, so some may find scones less flavorful.

Ideal for low-sugar or diabetic-friendly scones, but expect a slight difference in taste and sweetness intensity.

Quick tip: Granulated sugar is coarser and may cause slight graininess in the dough and final scone texture.

Using granulated sugar directly in scones is possible but less ideal because the larger crystals do not dissolve as quickly, potentially resulting in a slightly gritty texture.

To minimize this, mix thoroughly and consider resting the dough to allow sugar to hydrate.

The final scones may have a crunchier texture and less uniform sweetness compared to those made with powdered sugar.
