🛒 Ingredients
For the Sponge Cake:
- 4 large eggs (at room temperature)
- 100g caster sugar (plus extra for sprinkling)
- 75g all-purpose flour
- 25g high-quality cocoa powder
- 1 teaspoon baking powder
👩🍳 Step-by-Step Instructions
1. Prepare Your Baking Pan
Preheat your oven to 180°C (350°F). Line a round cake pan (about 8 inches) with parchment paper and lightly grease it.
2. Whip Eggs and Sugar
In a large mixing bowl, beat the eggs and caster sugar together using an electric mixer. Continue beating for 5–7 minutes until the mixture becomes pale, thick, and triples in volume. This step is crucial for a light sponge.
3. Sift Dry Ingredients
In a separate bowl, sift together the flour, cocoa powder, and baking powder. This ensures a smooth batter without lumps.
4. Fold Gently
Gradually fold the dry ingredients into the egg mixture using a spatula. Be gentle to maintain the airiness of the batter.
5. Bake to Perfection
Pour the batter into the prepared pan and smooth the top. Bake for 20–25 minutes, or until a toothpick inserted in the center comes out clean.
6. Cool and Serve
Allow the cake to cool in the pan for 10 minutes, then transfer to a wire rack. Sprinkle lightly with caster sugar if desired.
