Mastering the Classic Sponge Cake
A sponge cake is a test of patience and technique rather than ingredients. Master the aeration of your eggs, and you have the foundation for almost every classic dessert in the repertoire.
Temperature is your greatest ally.
Bring your eggs to room temperature before starting; they hold significantly more air than cold ones. Have your pans greased and lined with parchment before you even touch the whisk.

What goes in.
- 4 largeeggs, room temperature
- 1 cupgranulated sugar
- 1 cupcake flour, sifted
- 1/4 tspfine sea salt
- 1 tspvanilla extract
Watch the trail
When you lift the whisk, the batter falling back into the bowl should leave a visible trail on the surface for several seconds. If it disappears instantly, keep whisking.
The method.
Prep the oven
Preheat your oven to 350°F (175°C). Line the bottom of your pan with parchment; do not grease the sides, as the batter needs to climb them to rise.
Whip the base
Place eggs and sugar in the mixer bowl. Whisk on high for 8 to 10 minutes. The mixture must triple in volume and turn a pale, creamy white.
Fold with intent
Sift the flour and salt over the egg mixture in three batches. Use a wide silicone spatula to cut down through the center, scrape the bottom, and fold over, turning the bowl as you go.
Bake
Pour into the pan and smooth the top. Bake for 25 to 30 minutes. It is done when the top springs back when touched lightly.
Cool
Invert the pan onto a wire rack immediately. Let it cool completely in the pan before running a thin knife around the edges to release it.
Other turns to take.
Lemon Sponge
Add the zest of one lemon during the final minute of egg whisking.
Chocolate Sponge
Replace 2 tablespoons of cake flour with high-quality unsweetened cocoa powder.
When it doesn't go to plan.
Sift your flour twice to ensure it is light and free of clumps before it touches the eggs.
Never tap your spatula against the side of the bowl; you risk knocking out the air you just worked so hard to incorporate.
If the center of the cake sinks, it is a sign the eggs were under-whipped or the flour was folded in too aggressively.
The ones that keep coming up.
Can I use all-purpose flour?
You can, but the texture will be noticeably denser. Cake flour has a lower protein content, which is essential for that signature airy sponge.
Why didn't my cake rise?
The most common culprit is over-mixing the flour, which deflates the air bubbles, or not whisking the eggs long enough at the start.
