What is a Sponge Cake?
A sponge cake is a light, airy cake made primarily from whipped egg whites. Unlike butter or oil cakes, sponge cakes contain little to no fat, giving them their signature light texture. This cake is often used as a base for other desserts, such as layered cakes, trifles, or French-style pastries. You can also enjoy it on its own, dusted with powdered sugar, or paired with fresh fruit and whipped cream.
Why This Recipe Stands Out
Our sponge cake recipe stands out because it uses a combination of all-purpose flour and cornstarch, resulting in a lighter and airier texture. Many traditional sponge cake recipes use too much flour, making the cake heavy. By substituting some of the flour with cornstarch, we achieve a perfect balance that thickens the batter without forming excess gluten.
Ingredients for the Perfect Sponge Cake
- ⅓ cup (40 g) all-purpose flour
- ½ cup (60 g) cornstarch
- ¼ tsp baking powder
- ¼ tsp salt
- 4 large eggs (whites and yolks separated, room temperature)
- ⅛ tsp white vinegar
- ⅔ cup (132 g) white granulated sugar (divided into two parts)
- 1½ tbsp warm water
- 2 tsp vanilla extract
- 2 tbsp (30 g) unflavored vegetable oil (e.g., canola oil)
Step-by-Step Guide to Making Sponge Cake
1. Preheat and Prepare
- Preheat your oven to 160°C (320°F) with the fan on.
- Line the bottom of two 8×3 inch baking tins with baking paper. Do not grease the sides of the tins; leaving them bare prevents the cakes from shrinking after baking.
2. Mix Dry Ingredients
- In a bowl, combine the flour, cornstarch, baking powder, and salt. Mix until well combined. Set aside.
3. Whip Egg Whites
- In a medium-sized bowl, add the egg whites and white vinegar. Using a hand or stand mixer, whip on medium-high speed for 30 seconds until foamy.
- Gradually add ⅓ cup of sugar while continuing to mix for 2 minutes. Reduce the mixer speed to low and mix for an additional minute, achieving stiff peaks.
4. Whip Egg Yolks
- In a large bowl, combine the remaining ⅓ cup of sugar and warm water. Add the egg yolks and vanilla extract. Whip on medium-high speed for 4 minutes, then reduce to low and mix for another minute until the mixture is thick and ribbons form when lifted with a spoon.
- Stream in the vegetable oil while mixing on medium speed until well combined.
5. Combine Mixtures
- Gently fold half of the whipped egg whites into the egg yolk mixture using a spatula until just combined.
- Sift in the dry ingredients and gently fold through until just combined.
- Finish by adding the remaining egg whites and fold gently to maintain as much air as possible without overmixing.
6. Bake the Cake
- Distribute the batter evenly between the prepared baking tins. Tap the tins lightly on the counter to release any large air bubbles.
- Run a thin knife or toothpick through the batter to remove any remaining air bubbles.
- Bake for 25 minutes. To test doneness, gently touch the tops; they should create a small indent that slowly bounces back.
7. Cool the Cakes
- Once baked, tap the tins on the counter from a height of about 10cm and lay them upside down (while still in the tins) on a wire rack to cool completely. This prevents the cakes from deflating.
- After cooling for about an hour, run a thin knife around the edges to release the cakes from the tins, then turn them out onto a wire rack.
8. Apply Simple Syrup
- To keep your sponge cakes moist, brush them with simple syrup. Combine ½ cup of white granulated sugar with ½ cup of boiling water and stir until the sugar dissolves. Using a pastry brush, generously brush the tops and sides of the cakes with the syrup.
Decorating Your Sponge Cake
Now that you have your light and airy sponge cake, it’s time to get creative with cake decorating! Here are some ideas to inspire you:
1. Classic Victorian Sponge Cake
- Spread a thin layer of raspberry jam over one cake layer.
- Add halved strawberries and cover with a generous amount of whipped cream.
- Place the second cake layer on top and repeat with more whipped cream and strawberries.
2. Fresh Fruit and Whipped Cream
- Top your sponge cake with an assortment of fresh fruits like berries, kiwi, and mango.
- Add dollops of whipped cream around the edges for a beautiful finish.
3. Chocolate Ganache
- Drizzle warm chocolate ganache over the top of your sponge cake, letting it drip down the sides.
- Decorate with chocolate shavings or sprinkles.
4. Simple and Elegant
- Dust your sponge cake with powdered sugar and add a few edible flowers for a minimalist and elegant look.
Healthy Cake Recipes
If you’re looking for healthier cake options, here are a few ideas:
1. Whole Wheat Sponge Cake
- Substitute half of the all-purpose flour with whole wheat flour for added fiber and nutrients.
2. Gluten-Free Sponge Cake
- Use a gluten-free flour blend instead of all-purpose flour to make a gluten-free version of your sponge cake.
3. Sugar-Free Sponge Cake
- Replace the granulated sugar with a natural sweetener like stevia or monk fruit. Be mindful of the conversion rates, as these sweeteners are often much sweeter than sugar.
4. Low-Fat Sponge Cake
- Use reduced-fat or fat-free dairy products in your sponge cake recipe to cut down on calories and fat.
Delicious Cake Toppings
Enhance your sponge cake with these delicious and creative cake toppings:
1. Fresh Berries and Cream
- Top your cake with a mix of fresh berries and a generous layer of whipped cream.
2. Nutty Caramel Drizzle
- Drizzle caramel sauce over your cake and sprinkle with chopped nuts like pecans or walnuts.
3. Lemon Curd
- Spread a layer of tangy lemon curd over your sponge cake for a refreshing and zesty flavor.
4. Coconut and Pineapple
- Top your cake with a layer of coconut cream and fresh pineapple chunks for a tropical twist.
