Ingredients
- 4 egg whites
- 4 egg yolks
- 1 box sweetened condensed milk (approximately 395g / 14 oz)
- 2 cups cornstarch
Tools You’ll Need
- Electric mixer
- Two mixing bowls
- Spatula
- 8-inch round or loaf baking pan
- Oven
- Toothpick
Step-by-Step Instructions
1. Prepare the Oven & Pan
Preheat your oven to 180°C (350°F).
Grease your baking pan lightly with butter or oil and dust it with cornstarch. Tap out any excess.
2. Beat the Egg Whites
In a clean, dry bowl, beat the egg whites using an electric mixer until stiff peaks form.
They should be firm, glossy, and hold their shape when you lift the beaters.
Set aside.
3. Prepare the Cream Base
In another bowl, add:
- Egg yolks
- Condensed milk
- Cornstarch
Beat everything together until you get a smooth, light, homogeneous cream with no lumps.
4. Fold the Egg Whites
Add the beaten egg whites to the yolk mixture in 3 additions.
Using a spatula, gently fold with slow movements from bottom to top.
Do not stir aggressively — this keeps the cake light and airy.
The batter should remain fluffy.
5. Bake
Pour the batter into the prepared pan and smooth the top gently.
Bake for 20–25 minutes, or until the top is lightly golden.
6. Toothpick Test
Insert a toothpick into the center.
If it comes out clean, your cotton cake is ready.
Remove from the oven and allow it to cool slightly before unmolding.
