Ingredients (for a 9-inch round cake pan, 10 servings)

Cooking Time

• Preparation Time: 20 minutes
• Baking Time: 35-40 minutes
• Total Time: 55-60 minutes

Dry Ingredients

• 1 ¼ cups all-purpose flour (00 flour)
• ¼ cup unsweetened cocoa powder
• 1 pinch salt (⅛ tsp)

Wet Ingredients

• 6 medium eggs (room temperature)
• ¾ cup granulated sugar
• 1 teaspoon vanilla extract (or vanilla bean seeds/rum flavor optional)

Method

Step 1: Whipping the Eggs 🥚✨

1. Crack the room-temperature eggs into a large mixing bowl.
2. Add sugar, pinch of salt, and vanilla extract.
3. Using a stand mixer or hand mixer, beat the eggs on high speed for 15-20 minutes until they quintuple in volume and turn pale, thick, and fluffy.
4. Perform the “writing test” – lift the whisk and check if the batter leaves visible ribbons before sinking back.

Step 2: Mixing the Dry Ingredients 🍫

5. In a separate bowl, sift together the flour and cocoa powder (and baking powder if using).
6. Gently fold the dry ingredients into the whipped eggs using a spatula, stirring from bottom to top to avoid deflating the batter.

Step 3: Baking 🔥

7. Grease and flour a 9-inch round cake pan, or line it with parchment paper.
8. Pour the batter into the pan and smooth the top gently.
9. Bake in a preheated oven at 350°F (180°C) for 35-40 minutes. Do not open the oven for the first 30 minutes!
10. Check doneness with a toothpick test – insert a toothpick in the center; if it comes out clean, the cake is ready.
11. Once done, turn off the oven and leave the cake inside for 7-8 minutes before removing to prevent deflating.

Tips & Tricks for the Best Cocoa Sponge Cake 🏆

✅ Use room-temperature eggs – Cold eggs won’t whip properly.
✅ Whip eggs long enough – The batter must be fluffy and airy.
✅ Sift the flour and cocoa powder – Avoid lumps and ensure even mixing.
✅ Fold gently – Prevents deflating the batter.
✅ Preheat the oven – Ensures even baking.
✅ Do NOT open the oven too early – Can cause the cake to collapse.
✅ Store properly – Wrap in plastic wrap to keep fresh for 2-3 days, or freeze for up to a month.
