When baking gluten-free, you can achieve lighter, more tender results by applying a few reliable techniques. Below I explain step-by-step how to use each method and which approaches work best for specific applications.
Air is the key to lightness. Using an electric mixer at higher speed and beating longer incorporates more air into eggs, butter and sugar, and batters. The foaming method relies on whipping eggs into a voluminous, airy mixture and folding that into the batter to create light, springy baked goods. In gluten-free baking, this technique helps simulate the texture that gluten normally provides without relying on large amounts of extra starches such as potato, corn, tapioca, or arrowroot. The foaming method uses whole eggs and is appropriate for recipes that call for them, such as many cakes and some waffle batters.
With the foaming method you whip air into whole eggs, then gently fold the foam into the batter to preserve the trapped bubbles. Because this technique depends on whole eggs, use it only in recipes that include them.
Additional starch
Another way to lighten gluten-free baked goods is to increase the proportion of starches (potato, corn, tapioca). Arrowroot can sometimes lead to softer results and longer bake times, so many bakers prefer the other starches. If you want to avoid adding more starch for nutritional reasons, favor the foaming method instead.
To use this approach, replace part of the whole-grain flours (rice, sorghum, millet) with a starch. Traditional ratios go as high as about 60% starch to 40% flour, with some recipes using even higher starch content. A 60/40 starch-to-flour split is often considered a balanced compromise; some choose a 50/50 split for a slightly denser but still good result. Additional starch works well in yeast-based recipes, as well as in cakes and other sweets.
Sifting
Sifting dry ingredients lightens the final product by breaking up lumps and aerating the flour and starches. Sifting two to four times is common for very light cakes—more sifting generally produces lighter baked goods.
Creaming butter and sugar
When a recipe calls for creaming butter and sugar, make it your first step. Don’t stop when the ingredients are merely combined: beat until the mixture is noticeably pale and fluffy. Creaming incorporates air that helps leaven the batter. With a stand mixer, this often takes around five minutes, depending on the mixer speed and butter temperature.
How to use the whole egg (Genoise) foaming method
The Genoise is a classic sponge cake that typically uses the whole-egg foaming method; a small amount of melted butter is sometimes folded in to tenderize the crumb. This technique produces an airy structure without adding heavy starches.
Before you begin, measure all ingredients and prepare and grease pans. The foam created from beaten eggs can deflate quickly, so have everything ready before you start.
Using room-temperature eggs is important: cold eggs foam less effectively. Having all ingredients at or near room temperature helps produce a lighter result.
Ingredients:
Whole eggs at room temperature and any sugar the recipe requires.
Directions:
- Whisk the whole eggs and sugar in a heatproof bowl set over gently simmering water (about 110ºF). Warming the eggs while whisking increases volume and stability.
- Transfer the warmed mixture to a mixer bowl and beat on high until a stiff, glossy foam forms—this can take about 8–12 minutes, depending on mixer power.
- Test the foam by dropping a spoonful on top of the mixture and counting slowly to five; the dollop should not fully sink before you reach five. If it collapses sooner, continue beating.
- Fold the foamed eggs into the remaining batter gently with a rubber or silicone spatula, adding one-third of the batter at a time to preserve air.
- Add any other liquid ingredients slowly; if they are warm, add them gradually to temper the eggs and avoid cooking them.
- Bake according to the recipe, but watch the time: batters with a lot of incorporated air often bake faster than denser ones.
How to use the separated egg (sponge) foaming method
For very light sponge cakes such as ladyfingers, tiramisu layers, or roulades, separating eggs and whipping the whites independently creates an even more delicate crumb.
- Begin with room-temperature eggs. Separate the whites from the yolks while keeping any yolk out of the whites.
- Beat the egg whites to soft or stiff peaks depending on how dry or moist you want the finished product. Stiff peaks give the lightest, drier structure and are ideal when little or no fat is used.
- Prepare the rest of the recipe, beating yolks where the recipe calls for whole eggs.
- If the batter contains relatively few liquid ingredients and the whipped whites represent most of the wet volume, incorporate the dry ingredients in thirds and fold in half of the beaten whites alternately. Repeat until everything is combined to maintain maximum volume.
Tips
Do not use these aeration methods when you want a dense, heavy texture—examples include quick breads, traditional pound cakes, and some red velvet recipes. In those cases, combine sugar with dry ingredients rather than creaming it with butter.
Remove baked goods from pans promptly to prevent steaming the bottoms and softening the crust.
Allow bread to cool properly before slicing; slicing too soon can cause collapse. For very soft enriched breads, cooling upside down helps maintain loft. For example, panettone is commonly cooled inverted by suspending it with wooden skewers so it retains its open crumb.
