Ingredients
For the Sponge Cake:
- 4 large eggs
- 1 cup granulated sugar
- 1 cup all-purpose flour
- 1 teaspoon baking powder
- 1/2 teaspoon salt
- 1 teaspoon vanilla extract
- 1/4 cup milk
For the Custard Topping:
- 2 cups milk
- 1/2 cup granulated sugar
- 1/4 cup cornstarch
- 3 egg yolks
- 1 teaspoon vanilla extract
- 2 tablespoons unsalted butter
Directions
Step 1: Preheat the Oven
Preheat your oven to 350°F (175°C) and line a round cake pan with parchment paper. This ensures the cake doesn’t stick to the pan after baking.
Step 2: Prepare the Sponge Cake
In a large bowl, beat the eggs and granulated sugar together until the mixture is pale and fluffy. This will create the light and airy texture that is characteristic of sponge cake.
Step 3: Add Dry Ingredients
In a separate bowl, sift together the flour, baking powder, and salt. Gently fold these dry ingredients into the egg and sugar mixture, being careful not to deflate the batter.
Step 4: Add Wet Ingredients
Stir in the vanilla extract and milk until the batter is just combined. This will help create the smooth consistency necessary for a light, tender cake.
Step 5: Bake the Cake
Pour the batter into the prepared cake pan and bake for 25-30 minutes, or until a toothpick inserted into the center comes out clean. The cake should be golden brown on top and spring back when lightly touched.
Step 6: Cool the Cake
Let the cake cool in the pan for 10 minutes, then turn it out onto a wire rack to cool completely. This prevents the cake from becoming soggy.
Step 7: Prepare the Custard Topping
While the cake is cooling, prepare the custard topping. In a medium saucepan, whisk together milk, sugar, and cornstarch over medium heat until the mixture begins to simmer. This will activate the cornstarch and help thicken the custard.
Step 8: Temper the Egg Yolks
In a small bowl, whisk the egg yolks until smooth. To temper the yolks, slowly pour a small amount of the hot milk mixture into the egg yolks while whisking constantly. This gradually increases the temperature of the eggs without cooking them.
Step 9: Cook the Custard
Pour the tempered yolks back into the saucepan and continue to cook the mixture, stirring constantly, until it thickens and coats the back of a spoon. Be sure not to let it boil, as this could cause the custard to curdle.
Step 10: Finish the Custard
Remove the saucepan from the heat and stir in the vanilla extract and unsalted butter. Stir until the butter is fully melted and the custard is smooth and glossy.
Step 11: Assemble the Cake
Once the cake has cooled, place it on a serving plate. Pour the warm custard over the top of the sponge cake, spreading it evenly with a spatula to cover the entire surface.
Step 12: Set the Custard
Allow the custard to set slightly before slicing into the cake. This will ensure the custard stays on top of the cake and doesn’t run off.
Serving Suggestions
- Serve this cake as a light dessert after a hearty meal or as a sweet treat for afternoon tea.
- Add fresh fruit like berries or sliced bananas on top of the custard for a fresh contrast to the richness of the cake.
- Pair with a cup of coffee or tea to complement the light sweetness of the cake.
Cooking Tips
- Be sure to not overmix the batter when adding the dry ingredients. Gentle folding ensures that the sponge cake remains light and airy.
- If you want a thicker custard, you can increase the amount of cornstarch slightly.
- For a different flavor profile, consider adding a dash of almond extract or lemon zest to the sponge cake batter.
- To make sure the custard doesn’t curdle, always temper the egg yolks by slowly adding a bit of the hot mixture to them before mixing with the rest of the custard.
