Airy White Cake Recipe: Buttermilk-Baked Height With No Soggy Bottom

This airy white cake recipe delivers the perfect balance of height and tenderness—no soggy bottom in sight. The secret lies in buttermilk, which creates a tender crumb and helps the cake rise to impressive heights while maintaining a delicate texture.

I've perfected this method over years of baking, ensuring every slice is light enough to float on air.

What sets this recipe apart is the creaming method, where butter and sugar are beaten to incorporate air before adding dry ingredients. This technique, combined with precise oven temperature control, guarantees a cake that's tall, fluffy, and structurally sound.

The result? A golden, domed cake with a velvety texture that melts in your mouth.

Once baked, the cake's light, airy crumb makes it ideal for layering with whipped cream or delicate buttercream. The buttermilk also adds subtle tanginess that balances sweetness without overpowering the delicate vanilla flavor.

This is the kind of cake that feels special enough for celebrations but simple enough for everyday treats.

Ready in just under an hour, this recipe requires minimal effort but delivers restaurant-quality results. The key is patience—letting the batter rest before baking ensures even rising, while careful monitoring prevents overbrowning. Perfect for birthdays, weddings, or simply satisfying a sweet tooth, this cake never disappoints.

Ingredients for airy white cake

Twelve essential ingredients transform into a towering, golden cake with a velvety crumb.

The butter and sugar are the foundation—room temperature butter is non-negotiable for proper creaming. Store-bought butter works, but European-style unsalted (like Plugrá) yields superior flavor. For sugar, superfine dissolves effortlessly, but pulse regular granulated in a food processor if needed. Eggs should be room temperature—cold eggs cause dense cakes. The buttermilk is critical; if unavailable, combine 1 cup milk with 1 tbsp vinegar or lemon juice and let sit 5 minutes. Freshly grated lemon zest brightens the flavor without overpowering the delicate vanilla. For the dry ingredients, sift the flour to prevent lumps and ensure even distribution throughout the batter.

No buttermilk? Substitute with 1 cup plain yogurt thinned with 1 tbsp milk. Short on vanilla? Almond extract at half the amount adds depth. The cream of tartar stabilizes egg whites—omit only if you're whipping them separately for another use. Cake flour isn't mandatory, but its lower protein content creates an extra-tender crumb. For vegetable oil, any neutral oil (like canola) works for greasing. The lemon zest can be substituted with orange zest for a different citrus note, but reduce to 0.5 tbsp to avoid bitterness. Diamond Crystal baking powder is slightly lighter than other brands—use 1.5 tsp if using aluminum-free brands like Rumford.

Store butter at room temperature for 1 hour before creaming. Room temperature eggs take 30 minutes in warm water if rushed. The batter should rest 10-15 minutes before baking—this relaxes the gluten for a finer crumb. Grease pans thoroughly with oil and dust with flour or cake flour. Room temperature batter bakes more evenly; don't refrigerate. Freshly baked cakes cool completely before frosting to prevent sogginess. Leftovers keep 3 days at room temperature or 1 week refrigerated, though this cake is best enjoyed fresh. Freeze slices wrapped tightly for up to 3 months—thaw at room temperature.

Step-by-step instructions for airy white cake

Mastering this method guarantees a towering, moist cake with no dense bottom.

In a medium bowl, whisk together the 2 cups all-purpose flour, 0.5 cup cake flour, 2 tsp baking powder, 0.5 tsp salt, and 1 tbsp cornstarch. Sift the dry ingredients through a fine-mesh sieve directly into the bowl to eliminate any lumps. This creates a lighter crumb by preventing dense pockets in the batter.

Set aside the flour mixture until needed. I like to keep it in the bowl with the sifter—it saves time later when combining with wet ingredients. The cake flour adds extra lightness, but the all-purpose flour provides structure to support the cake's height.

In a separate, spotlessly clean bowl, combine the 4 whole large eggs and 1 tsp cream of tartar. Whisk briefly to blend, then transfer to a stand mixer fitted with the whisk attachment. Beat on medium speed until soft peaks form, about 3 minutes. Increase to high speed and continue beating until stiff, glossy peaks form that hold their shape when the whisk is lifted.

This step is critical for achieving that signature airy texture. The cream of tartar stabilizes the egg whites, helping them hold more air and creating a lighter cake. If your kitchen is humid, chill the bowl and beaters for 10 minutes before starting—this prevents the whites from over-beating or deflating.

In a large bowl, beat the 1 cup softened unsalted butter and 2 cups granulated sugar on medium speed until light and fluffy, about 4-5 minutes. The mixture should nearly double in volume and be pale yellow. Scrape down the sides of the bowl with a spatula to ensure even creaming.

This step incorporates air into the batter, which will expand in the oven and create that signature height. I use a paddle attachment for this part—it distributes the butter and sugar more evenly than a whisk. If your butter isn't quite soft enough, let it sit at room temperature for another 5-10 minutes before continuing.

Add the 1 cup buttermilk and 2 tsp pure vanilla extract to the butter-sugar mixture. Beat on low speed until just combined, about 30 seconds. In a separate bowl, combine the 1 tbsp lemon zest with 0.25 cup vegetable oil. Stir well to distribute the zest evenly in the oil.

The buttermilk adds moisture and tenderness to the cake while the lemon zest infuses subtle citrus brightness. Adding the oil with the zest ensures even distribution throughout the batter. Don't overmix at this stage—just combine until smooth. Overmixing develops gluten, which can make the cake dense.

With the mixer on low speed, gradually add one-third of the dry flour mixture to the wet ingredients. Mix just until combined, then add another third and mix again. Finally, add the remaining flour mixture and mix on low speed until the batter is smooth and just combined. Using a spatula, gently fold in the whipped egg whites in three additions, being careful not to deflate them.

This folding technique maintains the air incorporated in the egg whites while evenly distributing the dry ingredients. Work quickly but gently—you want to preserve those air pockets that will create the cake's light texture. If the batter looks slightly lumpy, that's okay; it will smooth out as you pour it into the pans.

Preheat your oven to 350°F. Grease two 9-inch round cake pans with vegetable oil and line the bottoms with parchment paper. Divide the batter evenly between the pans and smooth the tops. Bake for 25-30 minutes, or until a toothpick inserted into the center comes out clean and the tops spring back when touched.

The buttermilk in the batter helps create steam during baking, which contributes to that signature height. Don't overbake—the cake will continue cooking slightly as it cools. If the tops brown too quickly, tent the pans with aluminum foil to prevent over-browning while maintaining even cooking.

Essential equipment for this dish

Stand Mixer Must-Have

Invest in a quality stand mixer with a paddle attachment and whisk attachment—this is non-negotiable for achieving that signature airy texture. I use my KitchenAid Artisan Series for its consistent power and durability.

The paddle attachment ensures even creaming of butter and sugar, while the whisk attachment whips egg whites to stiff peaks without overmixing. A hand mixer works in a pinch, but you'll need to work in stages to avoid overheating the motor.

Precision Baking Tools

Start with 9-inch round cake pans—I prefer Wilton Perfect Results pans for their even heat distribution. Grease them thoroughly with vegetable oil and line the bottoms with parchment paper to prevent sticking.

A fine-mesh sieve is essential for sifting dry ingredients, eliminating lumps that can create dense pockets in the cake. For measuring, use a digital kitchen scale for accuracy—1 cup all-purpose flour can weigh 120-125 grams, but scales remove guesswork.

Temperature Control

An oven thermometer is a game-changer—many home ovens run 15-25°F hotter than set. I use a Thermoworks Oven Thermometer to ensure my oven hits 350°F accurately. For even baking, place a baking stone on the middle rack and let it preheat for 20 minutes before baking.

If your kitchen gets hot, chill the cake pans in the freezer for 10 minutes before baking to prevent over-browning.

Egg White Stabilizers

For stubborn egg whites, keep a cream of tartar and rubbing alcohol spray on hand. A 1 tsp cream of tartar stabilizes the whites, while a light spray of rubbing alcohol (about 1-2 sprays) can revive slightly deflated whites.

Store your mixing bowls in a cool, dry place—humidity is the enemy of stiff peaks. A chilled mixing bowl (place in freezer for 10 minutes) helps in humid conditions.

Batter Resting Tools

Let the batter rest for 10-15 minutes before baking—this relaxes the gluten for a finer crumb. Use a spatula to gently fold in egg whites, preserving their airiness. A kitchen timer ensures you don't overbake—the cake should spring back when touched and register 210°F at the center.

For testing doneness, keep a toothpick handy near the oven.

Cooling Essentials

After baking, transfer cakes to a wire cooling rack immediately to prevent sogginess. A fan helps speed up cooling, especially in humid climates. For layering, use a serrated knife to level the tops—this creates even surfaces for frosting.

Store leftovers in an airtight container at room temperature for 3 days or refrigerate for 1 week to maintain freshness.
