4. Step-by-Step Instructions: Layering for the Perfect Slice
Step 1: Prepare the Sponge Cake
Preheat your oven to 180°C (350°F) and grease a rectangular or round baking pan.
In a bowl, whisk together flour, baking powder, and a pinch of salt.
In another bowl, beat eggs and sugar until pale and fluffy.
Add melted butter and vanilla extract, mixing gently.
Fold in the dry ingredients until just combined.
Pour into the pan and bake for 20–25 minutes or until golden and springy.
Let the cake cool completely, then slice it horizontally into two even layers.
Step 2: Make the Silky Custard Filling
Heat milk in a saucepan until just warm (not boiling).
In a separate bowl, whisk egg yolks, sugar, and cornstarch until smooth.
Slowly pour warm milk into the egg mixture, whisking constantly.
Return the mixture to the saucepan and cook over medium heat.
Stir continuously until thick and creamy.
Remove from heat, add vanilla extract, and let it cool completely (cover with plastic wrap touching the surface to avoid a skin).
Step 3: Assemble the Cake
Place the bottom sponge layer on a serving plate.
Spread the cooled custard generously over the surface.
Gently place the second sponge layer on top.
Press lightly to level.
