 Why This Chocolate Sponge Cake Is Special

This chocolate sponge cake is light, fluffy, and filled with deep chocolate flavor without being overly sweet or dense. Unlike heavier chocolate cakes, this sponge relies on beaten eggs for structure — no baking powder or baking soda required. It’s perfect for:

• Birthday cakes

• Layer cakes with whipped cream or ganache

• Afternoon tea

• Elegant desserts with fruit or mousse

 Ingredients

Dry Ingredients:

• ¾ cup (90g) all-purpose flour

• ¼ cup (30g) unsweetened cocoa powder (Dutch-process or natural)

• ½ teaspoon salt

Wet & Binding Ingredients:

• 6 large eggs, at room temperature

• ¾ cup (150g) granulated sugar

• 1 teaspoon vanilla extract

• 2 tablespoons milk (optional – for added moisture)

• 2 tablespoons melted butter (cooled slightly, optional for richness)

 Equipment Needed

• 8-inch or 9-inch round cake pan (or two for layers)

• Electric mixer (hand or stand)

• Mixing bowls

• Fine mesh sieve or sifter

• Rubber spatula

• Parchment paper

• Cooling rack

 Time & Skill Breakdown

Skill Tip: This cake requires properly whipped eggs for structure, so take care during mixing and folding.

 Step-by-Step Instructions

 Step 1: Preheat & Prepare Pan

• Preheat oven to 350°F (175°C).

• Line the bottom of your cake pan with parchment paper (don’t grease the sides — it helps the sponge climb and rise).

 Step 2: Sift Dry Ingredients

In a bowl, sift together:

• Flour

• Cocoa powder

• Salt

Sifting eliminates lumps and aerates the mix — important for a fluffy sponge.

 Step 3: Whip Eggs & Sugar

In a large mixing bowl:

1. Add 6 eggs and granulated sugar.

2. Beat using an electric mixer on high speed for 8–10 minutes until the mixture is thick, pale, and ribbon-like.

Ribbon stage: When you lift the beaters, the batter should fall like a ribbon and slowly disappear into the mixture. This is critical!

 Step 4: Add Vanilla & Milk (Optional)

• Gently mix in the vanilla extract.

• If desired, stir in 2 tablespoons milk to add moisture.

 Step 5: Fold in Dry Ingredients

1. Sift the dry ingredients again, this time in thirds, directly over the egg mixture.

2. Use a rubber spatula to fold gently. Don’t stir or you’ll deflate the batter.

Go slow, be gentle. Over-mixing or rough folding will collapse the air bubbles.

 Step 6: Add Melted Butter (Optional)

• If using, drizzle cooled melted butter around the edge of the batter and gently fold it in.

• This adds a bit of richness, but the cake stays light.

 Step 7: Pour & Bake

1. Pour the batter into your prepared cake pan.

2. Gently tap the pan on the counter to release air bubbles.

3. Bake for 25–30 minutes, or until the top springs back when gently pressed and a toothpick comes out clean.

 Step 8: Cool Completely

• Let the cake cool in the pan for 10 minutes.

• Run a knife around the edge, then invert onto a cooling rack.

• Peel off the parchment paper and allow it to cool fully before slicing or layering.
