Sponge cake is a true classic – simple in ingredients, yet challenging in execution. Sometimes it rises beautifully, other times it sinks or cracks. The good news? There are reliable techniques that will help you bake a sponge cake that’s always even, fluffy, and light as air.
In this article, I’ve gathered the best methods for achieving a sponge cake that works every time.
1. Line only the bottom of the pan
This is a trick many bakers swear by.
➡️ Line only the bottom of the pan with baking paper, and leave the sides ungreased and unlined.
This way the batter can “cling” to the sides, rise evenly, and stay tall after baking.
2. Properly whipped eggs
A fluffy sponge starts with perfectly beaten eggs.
Separate the yolks from the whites.
Beat the egg whites in a clean, dry bowl until stiff peaks form.
Gradually add sugar, then the yolks.
The mixture should be pale, thick, and airy – the perfect base for your sponge.
3. Sifted flour and gentle folding
Always sift the flour – ideally twice. This adds lightness and prevents lumps.Add the flour in small portions and fold it in gently with a spatula, moving from the bottom up.
❌ Avoid using a mixer at this stage – it can deflate the batter and make the cake dense.
4. The right baking temperature
Eggs should be at room temperature.
Preheat the oven to 170–180°C (340–355°F).
Do not open the oven during the first 20 minutes of baking.
These small details help prevent sinking or a soggy center.
5. Cooling the sponge
There are two schools of thought here:
Dropping the pan – right after baking, drop the pan with the cake from a height of about 20–30 cm (8–12 inches) onto the counter. This releases air bubbles and prevents sinking.
Gentle cooling – if you don’t want to drop it, leave the cake in the oven with the door slightly open for 10–15 minutes, or place the pan upside down on a rack.
Both methods help keep the sponge level and fluffy.
Summary
The perfect sponge cake is a matter of combining a few simple rules: properly whipped eggs, gently folded flour, the right baking temperature, and smart pan preparation.
The easiest and most effective trick? ➡️ Line only the bottom of the pan and cool the sponge gently.With these techniques, your sponge will always rise evenly and come out just right.
