The Secret to Making a Fluffy and Light Sponge Cake

Ingredients for Baking

Flour is the main ingredient that gives structure to cakes and helps them rise. Typically, all-purpose flour or cake flour with a protein content of 7-9% is used.

Cornstarch plays a similar role to flour but makes the cake softer and fluffier. Usually, when mixing flour and cornstarch, the ratio is 1:1, 2:1, or 3:1.

Eggs add aroma and color to the cake. During the process of whisking egg whites, numerous air bubbles are created, and the more delicate the bubbles, the softer and fluffier the cake will be.

Sugar sweetens the cake and helps stabilize the whipped egg whites.

Butter or oil adds moisture to the cake, ensuring it is soft and fluffy, and creating a melt-in-your-mouth sensation when eaten.

How to Whisk Eggs

This step is crucial in determining the fluffiness of the cake. Over-whisking or under-whisking can affect the desired texture.

Step 1: Use an electric mixer at medium speed until large bubbles form.

Step 2: Add cream of tartar or lemon juice and continue whisking until small, fine bubbles appear.

Step 3: Divide the powdered sugar into three parts. Add the first part and whisk until it is fully incorporated, and the small bubbles start to disappear.

Step 4: Add the second part of sugar and whisk until the egg whites are soft and a clear white color.

Step 5: Finally, add the remaining sugar and whisk at medium speed for 30-45 seconds, then increase the speed and whisk for another 20-30 seconds.

To check if the eggs are whisked enough, look for a creamy white color. Gently lift the whisk, and if the peak stands upright, it is ready. If it flops over too much, whisk for another 15-20 seconds at high speed.

Techniques for Mixing Batter

Always follow these steps in sequence: Cut – Fold – Turn.

Cut: Use a spatula to cut through the mixture, touching the bottom of the bowl.

Fold: Gently lift the spatula, bringing the bottom layer of the mixture to the top.

Turn: Rotate the spatula around the bowl and return to the starting point.

Perform these actions gently to quickly incorporate the ingredients, saving time and minimizing the loss of air bubbles.

Proper Baking Techniques

Always remember to line the pan with parchment paper or grease it with butter.

Do not place the cake too high in the oven, close to the heating element. It is best to bake it in the middle racks.

Bake the cake at a temperature between 150-170°C for 20-25 minutes. Once baked, do not remove it immediately. Turn off the oven and leave the cake inside for about 10 minutes to prevent thermal shock.

With these tips, you can confidently bake a soft, fluffy, and delicious sponge cake. Good luck!
