Ingredients
For the Sponge Cake:
- 4 large eggs (room temperature)
- 1 cup (200g) granulated sugar
- 1/2 cup (120ml) whole milk (room temperature)
- 1/2 cup (120ml) vegetable oil
- 1 tsp vanilla extract
- 1 1/2 cups (190g) all-purpose flour
- 1 1/2 tsp baking powder
- 1/4 tsp salt
For the Custard Cream:
- 3 cups (720ml) whole milk
- 3 large egg yolks
- 3/4 cup (150g) granulated sugar
- 1/3 cup (40g) cornstarch
- 1 tsp vanilla extract

For Assembly and Topping:
- 1 cup (240ml) heavy whipping cream
- 2 tbsp powdered sugar
- Fresh fruit (berries, mango slices, or kiwi) or chocolate shavings (optional)
Instructions
1. Prepare the Sponge Cake:
- Preheat the oven to 350°F (175°C). Line two 9-inch (23 cm) round cake pans with parchment paper and lightly grease.
- In a large mixing bowl, whisk eggs and sugar using an electric mixer until pale and fluffy (5–7 minutes).
- Gradually mix in milk, oil, and vanilla extract on low speed.
- Sift together flour, baking powder, and salt. Gently fold into the wet ingredients until fully incorporated.
- Divide batter evenly between the pans. Bake for 20–25 minutes, or until a toothpick inserted in the center comes out clean.
- Let the cakes cool in pans for 10 minutes, then transfer to a wire rack to cool completely.
2. Make the Custard Cream:
- Heat milk in a medium saucepan over medium heat until warm but not boiling.
- In a separate bowl, whisk together egg yolks, sugar, and cornstarch until smooth.
- Gradually pour the warm milk into the egg mixture, whisking constantly. Return the mixture to the saucepan.
- Cook over medium heat, whisking constantly, until thickened (about 5 minutes).
- Remove from heat, stir in vanilla extract and butter until smooth. Cover with plastic wrap, pressing it directly onto the surface, and let cool completely.
3. Whip the Cream:
- In a cold mixing bowl, beat heavy cream and powdered sugar until stiff peaks form. Keep chilled.
4. Assemble the Cake:
- Slice each sponge cake horizontally to create 4 thin layers.
- Place one cake layer on a serving plate. Spread a layer of custard cream over it. Repeat with remaining layers, ending with a cake layer on top.
- Cover the entire cake with whipped cream, smoothing it out with a spatula.
5. Decorate and Serve:
- Garnish with fresh fruit or chocolate shavings if desired. Chill for at least 2 hours before slicing for clean layers.
