Australian Sponge Cake Recipe: Fluffy Vanilla Cloud With Buttery Layers

This Australian sponge cake recipe delivers the signature light-as-air texture that makes it legendary at afternoon tea. The secret lies in folding egg whites to cloud-like perfection—no dense crumbs here, just tender layers that practically melt in your mouth. I've perfected this version after years of testing, ensuring every slice stays moist and fluffy long after baking.

What sets this recipe apart is the traditional method of creaming butter and sugar until pale and fluffy, then gently folding in egg whites for that signature Australian lightness.

The cake bakes at 350°F for about 25 minutes, resulting in a golden dome with a tender crumb that's impossible to resist. This is the kind of cake that feels like a warm hug—ideal for celebrations or simply treating yourself.

The real magic happens when you fill it with vanilla buttercream or jam—though purists often enjoy it plain, just as it came from the oven. Each slice reveals those delicate layers, proof that good things come to those who fold their egg whites properly.

Whether you're baking for Anzac Day or a cozy afternoon tea, this recipe delivers every time.

Ingredients for australian sponge cake

Nine simple ingredients transform into a cloud-like Australian sponge cake that's light, tender, and perfect for afternoon tea.

The butter is non-negotiable here—European-style unsalted butter gives that signature richness. Plugrá or President brands are my go-to, but any good-quality butter works. Don't skip the room-temperature step—it's what creates those delicate layers. The eggs? Room temperature is key for maximum volume. If you're in a rush, separate the yolks and whites, then warm the yolks slightly in a bowl over hot water (no boiling!). The flour? King Arthur or Gold Medal are my favorites—they're sifted and measured properly for that perfect crumb.

No vanilla extract? Vanilla bean paste works too, or even a scraped vanilla bean. Short on baking powder? Baking soda plus cream of tartar at half the amount gets you close. The milk can be swapped for cream or even water in a pinch, but whole milk gives the best texture. For the filling, homemade vanilla buttercream is ideal, but store-bought works too. Just make sure it's not too sweet—this cake shines on its own. The jam? Raspberry or strawberry are classic, but any fruit jam will do.

This cake is best served the day it's made—24 hours is ideal for the flavors to meld. Store wrapped tightly at room temperature for up to 3 days, or in the fridge for 5 days. Freeze slices for 3 months if you want to prep ahead. The secret to reheating? 10 seconds in the microwave—just enough to warm the buttercream without drying out the cake. I always make a double batch—one for tea, one for leftovers that disappear fast.

Step-by-step instructions for Australian sponge cake

Here's how to bake that signature fluffy, buttery Australian sponge—light as a cloud and packed with vanilla flavor.

First, let's get everything ready so we don't have to stop midway. In a medium bowl, whisk together the 2 cups all-purpose flour, 2 teaspoons baking powder, and ¼ teaspoon salt. Sift the flour mixture through a fine-mesh sieve directly into the bowl to aerate it—this creates a lighter texture. Set aside.

In a separate large bowl, beat the 1 cup softened unsalted butter and 1.5 cups granulated sugar together using an electric mixer on medium speed for about 3-4 minutes. You're looking for a light, fluffy mixture that's about double in volume and pale in color. This step incorporates air, which is crucial for that signature Australian sponge lightness.

With the mixer running on medium speed, add the 6 whole large eggs, one at a time, mixing well after each addition. Let each egg incorporate completely before adding the next. This gradual addition prevents curdling and ensures a smooth batter. After all eggs are added, mix in the ½ cup vegetable oil and ½ cup milk until just combined.

Here's the thing—don't overmix. The batter should be thick but still pourable. If you see streaks of flour, that's okay—we'll incorporate them in the next step. The key is to maintain that airy texture we created earlier. Add the 1 tablespoon vanilla extract and mix for another 10 seconds to distribute the flavor evenly.

With the mixer on low speed, gradually add the dry ingredients to the wet mixture. Mix just until the flour is mostly incorporated—you should still see a few streaks. Overmixing develops gluten, which makes the cake dense instead of light and fluffy. Once combined, pour the batter into three 8-inch round cake pans that have been lined with parchment paper and greased lightly with butter.

This three-pan method creates thin layers that we'll sandwich together later. Divide the batter evenly among the pans, tapping each pan gently on the counter to remove any air bubbles. The batter should fill each pan to about ½ inch depth—this ensures even baking and those signature thin layers.

Preheat your oven to 350°F. Place the pans on the middle rack and bake for 12-15 minutes, or until the tops are golden brown and a toothpick inserted into the center comes out clean. Don't overbake—Australian sponge should be tender, not cakey.

I like to check the cakes at the 12-minute mark because ovens vary. The edges should pull away slightly from the pan, and the cakes should spring back when gently pressed in the center. Remove from the oven and let the cakes cool in their pans for 5 minutes, then transfer to a wire rack to cool completely. This cooling step is crucial—it prevents the layers from tearing when we assemble them.

Once completely cool, place one cake layer on a serving plate. Spread ½ cup raspberry jam evenly over the top, leaving a ½-inch border uncovered. This jam layer is what makes this cake so special—it adds moisture and a perfect balance of sweet-tart flavor.

Add the 1.5 cups vanilla buttercream filling on top of the jam, spreading it evenly to the edges. Place the second cake layer on top, pressing down gently to create a seal. Repeat the process with the remaining jam and buttercream, then top with the final cake layer. Dust the top with a light layer of powdered sugar if desired, or serve as-is for a classic presentation.

Pro cooking tips for this dish

Egg White Mastery

The secret to that signature Australian lightness is in the egg whites—folding them in at the right moment. I always whip the whites to stiff peaks (not dry peaks) in a separate bowl before gently incorporating them into the batter in three additions.

Use a spatula to fold, cutting through the center and bringing the batter up from the bottom. This maintains air pockets without deflating them. If your whites are overwhipped, they'll collapse when mixed in—so keep an eye on that! 🥚

Butter Creaming

Creaming the butter and sugar is where the magic begins. Beat them together until light and pale—this can take 3-5 minutes with an electric mixer. The goal is to incorporate air, which creates that signature tender crumb.

I like to use a stand mixer for this step because it's more consistent than hand mixing. If your mixture looks grainy or doesn't lighten, your butter might not be soft enough—let it sit at room temperature for another 10 minutes.

Baking Time Precision

Australian sponge cakes bake fast—typically 12-15 minutes at 350°F. Overbaking is the #1 mistake—it turns the cake dense instead of fluffy. I check for doneness at 12 minutes by tapping the side of the pan: it should sound hollow.

A toothpick should come out with a few moist crumbs, not wet batter. Let the cakes cool completely in the pan for 5 minutes before transferring to a rack—this prevents them from cracking when assembled. ⏰

Layer Assembly Tips

When stacking your layers, level the cakes with a serrated knife if needed—uneven layers make for messy filling. Spread the jam only to the edges of the first layer to prevent sogginess. For the buttercream, use a spatula to create a clean border before adding the next layer.

Press down gently to seal the layers without crushing them. The final layer should be slightly domed for that classic presentation. 🍰

Equipment Upgrades

Invest in a 9-inch round cake pan if you want thicker layers, but stick to 8-inch for the traditional thin slices. I use Demeyer pans because they're non-stick and conduct heat evenly. For folding egg whites, a whisk attachment on your mixer gives better control than beaters.

And always use parchment paper—it prevents sticking and makes removal effortless. A digital thermometer helps monitor oven temp consistency, especially if your oven runs hot or cold. 🌡️
