Whether you’re making a simple birthday cake, a layer cake with frosting, or a trifle, a well-made sponge cake is essential. In this article, we’ll guide you through the process of making a delicious plain sponge cake, from gathering your ingredients to baking and cooling. By following these simple steps and tips, you’ll be able to create a light, fluffy, and moist sponge cake that everyone will enjoy.
Ingredients
Before you begin, make sure you have all the necessary ingredients on hand. Here’s what you’ll need:
- 2 cups (250g) all-purpose flour
- 2 cups (400g) granulated sugar
- 4 large eggs, at room temperature
- 1 teaspoon baking powder
- 1/2 teaspoon salt
- 1/2 cup (120ml) vegetable oil or melted unsalted butter
- 1 teaspoon vanilla extract
- 1 cup (240ml) whole milk, at room temperature
Equipment
You’ll also need some basic kitchen equipment to make your sponge cake:
- Mixing bowls
- Electric mixer or whisk
- Measuring cups and spoons
- Spatula
- Two 9-inch (23 cm) round cake pans, greased and lined with parchment paper
- Cooling rack
- Oven mitts
Step-by-Step Instructions
Now that you have your ingredients and equipment ready, let’s get started.
Preheat Your Oven
Begin by preheating your oven to 350°F (175°C). This ensures that your oven is at the correct temperature when you’re ready to bake, which is crucial for achieving an even bake and a perfectly moist cake.
Prepare Your Dry Ingredients
In a large mixing bowl, whisk together the flour, baking powder, and salt. This step combines the dry ingredients and ensures they’re evenly distributed, which will help your cake rise evenly and have a nice texture.
Mix Your Wet Ingredients
In a separate mixing bowl, add the eggs and granulated sugar. Use an electric mixer or whisk to beat the eggs and sugar together on medium speed until the mixture is pale yellow and thickened, about 3-4 minutes. This process is called “creaming,” and it helps to incorporate air into the batter, making your cake lighter and fluffier.
Once the egg and sugar mixture is thickened, gradually add the vegetable oil or melted butter, beating on medium speed until well combined. Then, add the vanilla extract and mix until incorporated.
Combine Wet and Dry Ingredients
With the mixer on low speed, gradually add the dry ingredients to the wet ingredients in three additions, alternating with the milk. Begin and end with the dry ingredients. Mix until just combined after each addition, being careful not to overmix. Overmixing can cause your cake to be dense and tough, so mix until the ingredients are just incorporated.
Pour the Batter Into the Cake Pans
Divide the batter evenly between the two prepared cake pans. Use a spatula to scrape all the batter out of the mixing bowl and spread it evenly in the pans. Smooth the top of the batter with the spatula to ensure an even bake.
Bake the Cakes
Place the cake pans in the preheated oven and bake for 25-30 minutes, or until a toothpick inserted into the center of each cake comes out clean. The cakes should be golden brown and should spring back to the touch when lightly pressed.
While the cakes are baking, prepare your cooling rack. Once the cakes are done, remove them from the oven and let them cool in the pans for about 10 minutes. This allows the cakes to set and makes them easier to handle.
Cool the Cakes Completely
After the cakes have cooled in the pans for 10 minutes, run a knife around the edges of the pans to loosen the cakes. Then, carefully remove the cakes from the pans and place them on the cooling rack to cool completely. Let the cakes cool for at least 1-2 hours before frosting or assembling your dessert.
Tips for Perfect Sponge Cake
While the basic recipe for a plain sponge cake is straightforward, there are a few tips and tricks to ensure your cake turns out perfectly every time.
Room Temperature Ingredients: Make sure your eggs, milk, and butter (if using) are at room temperature before you start. This helps the ingredients to mix together more easily and ensures a smoother batter.
Creaming the Butter and Sugar: If you’re using butter instead of oil, make sure it’s softened to room temperature before you cream it with the sugar. This helps the butter and sugar to mix together more easily and creates a smoother, more even batter.
Don’t Overmix: It’s important not to overmix the batter once you add the dry ingredients. Mixing just until the ingredients are combined helps to keep the batter light and airy, which results in a fluffier cake.
Measure Flour Correctly: When measuring flour, spoon it into the measuring cup and level it off with a knife. This ensures you don’t use too much flour, which can make your cake dry and dense.
Use Quality Ingredients: Using high-quality ingredients, such as fresh eggs, good-quality flour, and real butter (if using), will make a noticeable difference in the taste and texture of your cake.
Cool Completely: Let your cakes cool completely before frosting or assembling your dessert. This helps the cakes to set and ensures that the frosting or filling doesn’t cause the cakes to become soggy.
Variations and Additions
While a plain sponge cake is delicious on its own, there are many ways to customize and elevate your cake. Here are a few ideas to inspire you:
Flavor Extracts: Add a teaspoon of your favorite flavor extract, such as almond, lemon, or orange, to the batter for added flavor.
Coffee or Espresso: For a rich, mocha-flavored cake, add a tablespoon of instant coffee or espresso powder to the batter.
Berries or Fruit: Fold in a cup of fresh or frozen berries, chopped fruit, or dried fruit into the batter before baking for a fruit-filled cake.
Chocolate: For a chocolate sponge cake, add 1/2 cup (50g) of cocoa powder to the dry ingredients and increase the sugar to 2 1/2 cups (500g) for a richer, chocolatey flavor.
Spices: Add a teaspoon of ground cinnamon, nutmeg, or ginger to the batter for a warm, spiced cake.
