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:

1. • • 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.
2. 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.
3. 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.
