How to Make Sheet Sponge Cake

1. Prepare the Oven and Pan

Preheat your oven to 180°C (350°F).

Line a 9×13-inch baking tray with parchment paper, leaving a little overhang on the sides to make the cake easier to remove.

2. Combine the Dry Ingredients

In a medium bowl, whisk together the cake flour, baking powder, and salt.

Set aside.

3. Beat the Eggs and Sugar

In a separate large bowl, add the eggs and sugar.

Beat until the mixture becomes light, pale, and fluffy.

This step helps create a lighter sponge texture.

4. Add the Wet Ingredients

Add the vegetable oil, milk, and vanilla extract to the egg mixture.

Mix until everything is well combined.

5. Combine the Batter

Gradually add the dry ingredients to the wet mixture.

Gently fold until just combined.

Do not overmix, as overmixing can make the cake dense rather than soft and fluffy.

6. Bake

Pour the batter evenly into the prepared baking tray.

Smooth the surface with a spatula if necessary.

Bake in the preheated oven for 20–25 minutes, or until a toothpick inserted into the center comes out clean.

7. Cool

Remove the cake from the oven and allow it to cool completely before slicing or decorating.

Once cooled, you can cut it into squares or use it as a base for your favorite frosting and toppings.

Helpful Tips for a Fluffy Sponge Cake

• Make sure your baking powder is fresh.
• Beat the eggs and sugar until genuinely light and fluffy.
• Add the flour gradually.
• Fold the dry ingredients gently.
• Avoid overmixing once the flour is added.
• Don’t open the oven repeatedly while the cake is baking.
• Let the cake cool completely before decorating.

Storage

Store the cooled cake in an airtight container at room temperature for 1–2 days.

If decorated with cream or another perishable frosting, refrigerate it and consume according to the storage requirements of the topping.

You can also wrap the unfrosted cake tightly and freeze it for longer storage.

Frequently Asked Questions

Can I use all-purpose flour instead of cake flour?

Yes. Cake flour gives the cake a particularly tender texture, but all-purpose flour can be used if cake flour isn’t available.

How do I know when the cake is done?

Insert a toothpick into the center. If it comes out clean or with a few moist crumbs, the cake is ready.

Can I make this cake ahead of time?

Yes. Bake the cake a day ahead, allow it to cool completely, then wrap it tightly and store it until you’re ready to decorate and serve.
