Creating a perfectly light and airy 10-inch sponge cake is a rewarding baking project that yields a versatile base for layered cakes, desserts, or simply enjoyed on its own. Its delicate texture comes from careful whisking and precise folding, making it a staple in any baker’s repertoire. Whether you’re celebrating a special occasion or just craving a homemade treat, this recipe delivers a moist, fluffy sponge every time.
Ingredients
- 5 large eggs, at room temperature
- 150 grams (¾ cup) granulated sugar
- 150 grams (1¼ cups) all-purpose flour, sifted
- ½ teaspoon baking powder (optional, for extra lift)
- ¼ teaspoon salt
- 60 ml (¼ cup) whole milk or buttermilk
1 teaspoon vanilla extract
60 grams (¼ cup) unsalted butter, melted and cooled
Instructions
- Preheat your oven to 350°F (180°C). Grease a 10-inch round cake pan and line the bottom with parchment paper for easy removal.
- In a large mixing bowl, beat the eggs and sugar together on high speed using a hand or stand mixer. Whisk for about 8-10 minutes until the mixture becomes thick, pale, and doubled in volume. This step is crucial for a light sponge.
- Meanwhile, in a separate bowl, sift together the flour, baking powder (if using), and salt. Gradually add the sifted dry ingredients to the egg mixture in three additions, folding gently with a spatula after each addition to maintain volume.
- Warm the milk slightly and add the vanilla extract. Pour a third of the milk mixture into the batter and gently fold to combine. Repeat with the remaining milk, then add the melted butter, folding gently until just incorporated. Be careful not to deflate the batter.
- Pour the batter into the prepared cake pan, smoothing the top with a spatula. Tap the pan lightly on the counter to release any large air bubbles.
- Bake in the preheated oven for 25-30 minutes, or until the cake is golden and a toothpick inserted into the center comes out clean. Avoid opening the oven door too early to prevent collapsing.
- Once baked, remove the cake from the oven and let it cool in the pan for 10 minutes. Then, turn it out onto a wire rack and cool completely before frosting or serving.
Tips
- Use room temperature ingredients: Eggs, milk, and butter should be at room temperature to ensure a smooth, airy batter that traps air effectively.
- Don’t overmix: When folding in the dry ingredients, do so gently to preserve the volume from the whipped eggs. Overmixing can lead to a dense cake.
- Alternative flours: For a gluten-free version, substitute all-purpose flour with a gluten-free baking blend, but expect slight differences in texture.
- Storage: Keep the cooled sponge covered in plastic wrap or an airtight container for up to 2 days at room temperature or refrigerate for up to 3 days. Reheat gently if desired.
Serving Suggestions
This 10-inch sponge cake is incredibly versatile. Serve it plain with a dusting of powdered sugar or top with fresh berries and whipped cream for a light dessert. It also works beautifully as a base for layered cakes, filled with fruit preserves, pastry cream, or buttercream. For a more decadent presentation, consider frosting it with chocolate ganache or a classic buttercream.
Variations
Experiment with flavors by adding citrus zest, almond extract, or a splash of liqueur to the batter. You can also infuse the cake with spices like cinnamon or nutmeg for a seasonal twist. For a chocolate version, fold in cocoa powder (about 30 grams) and reduce the flour slightly to maintain the batter’s consistency.
Storage and Reheating
Wrap the cooled sponge tightly in plastic wrap or keep it in an airtight container. At room temperature, it stays fresh for up to 2 days. For longer storage, refrigerate for up to 3 days. To reheat, place slices in a microwave-safe dish and warm for 10-15 seconds, or gently reheat the whole cake in a low oven (around 300°F/150°C) for about 10 minutes. This helps restore moisture and softness before serving.
Frequently Asked Questions
Can I make this sponge cake dairy-free?
Yes, substitute the milk with almond milk, soy milk, or coconut milk, and replace butter with a dairy-free margarine or oil. The texture may vary slightly, but it will still be light and fluffy.
Why did my cake turn out dense?
Common causes include insufficient whipping of the eggs and sugar, overmixing after adding the flour, or opening the oven door too early during baking. Ensuring proper whipped eggs and gentle folding helps maintain the sponge’s airy structure.
What if I don’t have a 10-inch round pan?
You can use an 8-inch or 9-inch pan, but the baking time may vary slightly—check for doneness with a toothpick. Alternatively, you can bake the batter in two smaller pans and layer the cakes.
Can I freeze leftover sponge cake?
Absolutely. Wrap the cooled cake tightly in plastic wrap and place it in an airtight container or freezer bag. It can be frozen for up to 3 months. To serve, thaw at room temperature for a few hours before decorating or slicing.
How do I prevent the cake from collapsing?
Ensure you whip the eggs and sugar sufficiently to create a stable foam, avoid opening the oven during baking, and gently fold in the dry ingredients to preserve the air bubbles. Proper oven temperature is also key for even rising.
