Ingredients

• 150 grams all-purpose flour
• 20 grams cornstarch
• 1 teaspoon baking powder
• 100 grams unsalted butter
• 200 grams granulated sugar
• 4 large eggs
• 1 teaspoon vanilla extract
• 60 milliliters milk
• 0.5 teaspoon salt

Directions

Step 1

Preheat your oven to 175°C (350°F). Lightly grease and line a 20 cm (8-inch) round cake pan with baking paper.

Step 2

In a medium bowl, sift together the all-purpose flour, cornstarch, baking powder, and salt. Set aside.

Step 3

In a saucepan over low heat, melt the butter. Once melted, let it cool slightly.

Step 4

In a large mixing bowl, combine the granulated sugar and eggs. Using an electric mixer, beat the mixture on high speed until it becomes thick, pale, and almost triples in volume, about 5-6 minutes.

Step 5

Add the vanilla extract to the egg mixture and whisk briefly to incorporate.

Step 6

Gently fold the sifted dry ingredients into the egg mixture in three additions using a spatula. Ensure each addition is well incorporated before adding the next.

Step 7

Stir the warm melted butter and milk together. Gently fold this mixture into the batter until fully combined. Be careful not to deflate the batter.

Step 8

Pour the batter into the prepared cake pan and smooth the top with a spatula.

Step 9

Bake in the preheated oven for 30-35 minutes, or until the top is golden brown and a skewer inserted into the center of the cake comes out clean.

Step 10

Once baked, remove the cake from the oven and let it cool in the pan for 10 minutes. Then transfer it to a wire rack to cool completely.

Step 11

Slice the cooled sponge cake and serve it plain or with a dusting of powdered sugar.
