What Makes a Soft & Fluffy Vanilla Sponge Cake?
A true Soft & Fluffy Vanilla Sponge Cake is defined by its airy structure and subtle, sweet aroma. Unlike dense butter cakes, a sponge relies heavily on aerated eggs to provide lift. This method creates a “foam” base, resulting in a light-as-air finish that isn’t overly oily or heavy. It is the perfect versatile base for birthdays, afternoon tea, or simple snacking.
Ingredients
- 4 large eggs (at room temperature)
- 120g granulated sugar
- 120g cake flour (sifted)
- 30ml whole milk
- 20g unsalted butter (melted)
- 1 teaspoon pure vanilla extract
- 1/2 teaspoon cream of tartar
- A pinch of salt

Step-by-Step Preparation
1. Preheat and Prep: Begin by preheating your oven to 170°C. Line a 7-inch round cake tin with parchment paper. Do not grease the sides, as the sponge needs to “climb” the walls of the tin to reach its maximum height.
2. Separate the Eggs: Carefully separate the egg whites from the yolks. In a clean bowl, whisk the yolks with the vanilla extract and half of the sugar until the mixture becomes pale and creamy.
3. Whip the Meringue: In a separate large bowl, beat the egg whites with cream of tartar and salt. Gradually add the remaining sugar, whisking until stiff, glossy peaks form. This is the secret to a Soft & Fluffy Vanilla Sponge Cake.
4. Fold the Batter: Gently fold the yolk mixture into the egg whites using a spatula. Sift the cake flour over the mixture in three stages, folding very gently to keep the air bubbles intact.
5. Temper the Liquids: Mix the melted butter and milk together. Take a small scoop of the batter and stir it into the milk/butter mixture, then pour everything back into the main batter. Fold until just combined. 🥣
6. Bake to Perfection: Pour the batter into the prepared tin and tap it on the counter to remove large air bubbles. Bake for 30 to 35 minutes or until a toothpick comes out clean.

Pro Tips for the Best Soft & Fluffy Vanilla Sponge Cake
To ensure your Soft & Fluffy Vanilla Sponge Cake succeeds every time, focus on the temperature of your ingredients. Room temperature eggs whip up to a much larger volume than cold ones. Additionally, ensure your mixing bowl is completely grease-free before starting the meringue, as even a drop of fat can prevent the egg whites from stiffening.

Serving and Storage Tips
This Soft & Fluffy Vanilla Sponge Cake is best served with a light dusting of powdered sugar or a side of fresh berries and whipped cream. If you prefer a more indulgent treat, it holds up beautifully under a layer of lemon curd or strawberry jam. 🍓
For storage, wrap the cooled cake tightly in plastic wrap to prevent it from drying out. It stays fresh at room temperature for up to two days. If you need to keep it longer, store it in the refrigerator for up to five days, but be sure to let it come to room temperature before serving to restore its signature softness.
Frequently Asked Questions
Why did my sponge cake collapse?
The most common reason is underbaking or opening the oven door too early, which causes a sudden temperature drop before the structure is set.
Can I use all-purpose flour instead of cake flour?
Yes, but for the softest results, replace two tablespoons of the all-purpose flour with cornstarch to mimic the lower protein content of cake flour.
Do I need baking powder?
Traditional sponge cakes rely on whipped eggs for leavening, but you can add 1/2 teaspoon of baking powder if you are worried about the lift.
Mastering the Soft & Fluffy Vanilla Sponge Cake is a rewarding milestone for any baker. Its simplicity highlights the beauty of basic ingredients transformed through technique. Once you have perfected the base, the flavor combinations are endless.
