Custard Sponge Cake
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
Instructions:
- Preheat your oven to 350°F (175°C) and line a round cake pan with parchment paper.
- In a large bowl, beat eggs and sugar until pale and fluffy.
- Prepare the Sponge Cake:
- Sift together flour, baking powder, and salt. Gently fold into the egg mixture.
- Mix in vanilla extract and milk until just combined.
- Pour batter into the prepared pan and bake for 25-30 minutes, or until a toothpick inserted into the center comes out clean.
- Let the cake cool in the pan for 10 minutes, then turn out onto a wire rack to cool completely.
- Make the Custard Topping:
- In a medium saucepan, whisk together milk, sugar, and cornstarch over medium heat.
- In a small bowl, whisk the egg yolks, then temper them by slowly pouring in some of the hot milk mixture, whisking constantly.
- Pour the tempered yolks back into the saucepan and continue to cook, stirring constantly, until the mixture thickens and coats the back of a spoon.
- Remove from heat and stir in vanilla extract and butter until smooth.
- Assemble the Cake:
- Once the cake is cool, place it on a serving plate.
- Pour the warm custard over the top of the sponge cake, spreading to cover evenly.
- Allow the custard to set slightly before slicing.
