Ingredients

• 4 large Eggs
• 200 grams Sugar
• 100 grams All-purpose flour
• 50 grams Cornstarch
• 1 teaspoon Baking powder
• 1 teaspoon Vanilla extract
• 50 grams Butter (melted and cooled)
• 300 milliliters Whipping cream
• 100 grams Jam (berry or your preferred flavor)
• 2 tablespoons Powdered sugar (for dusting)

Directions

Step 1

Preheat your oven to 180°C (350°F) and grease two 8-inch round cake pans. Line the bottoms with parchment paper for easy removal.

Step 2

In a large mixing bowl, use an electric mixer on high speed to beat the 4 eggs and sugar together until the mixture is pale, thick, and tripled in volume (about 5-7 minutes).

Step 3

Sift the all-purpose flour, cornstarch, and baking powder together in a separate bowl.

Step 4

Gradually fold the sifted dry ingredients into the egg mixture using a spatula. Be gentle to maintain the airy texture.

Step 5

Add the vanilla extract and melted butter, folding gently until just combined. Be careful not to deflate the mixture.

Step 6

Evenly divide the batter into the prepared cake pans and smooth the tops with a spatula.

Step 7

Bake in the preheated oven for 20-25 minutes, or until the tops are golden and a toothpick inserted into the center comes out clean.

Step 8

Allow the cakes to cool in their pans for 10 minutes before turning them out onto a wire rack to cool completely.

Step 9

Once completely cool, whip the cream to stiff peaks in a chilled bowl using a hand mixer.

Step 10

Spread a generous layer of jam on top of one cake layer, followed by a thick layer of whipped cream.

Step 11

Place the second cake layer on top, pressing slightly to secure it. Dust the top with powdered sugar for a classic finish.

Step 12

Slice and serve immediately, or store in the refrigerator for up to 2 days.
