Instructions
Step 1: Prepare the Oven

Line the bottom of an 18 cm baking pan with parchment paper.
Step 2: Whip the Eggs
- Crack the eggs into a large mixing bowl.
- Add the sugar and vanilla extract.

Step 3: Add the Dry Ingredients
- Sift together the flour and cocoa powder.
- Gradually add the dry mixture to the whipped eggs.
- Fold gently with a spatula until fully incorporated.
Important: Avoid overmixing to preserve the air bubbles that help the cake rise.
Step 4: Bake
- Pour the batter into the prepared baking pan.
- Smooth the top gently.
- Bake at 170°C (340°F) for 35–40 minutes.
The cake is done when:

Step 5: Cool
Allow the cake to cool in the pan for about 10 minutes.
Transfer to a wire rack and let it cool completely before slicing or decorating.
