Rich Chocolate Custard Cake

🍫 Rich Chocolate Custard Cake

A luscious dessert with a tender cake top and a creamy, pudding-like custard layer underneath. It’s elegant but surprisingly simple to make.


📝 Ingredients (8-inch / 20 cm pan)

  • 115g (½ cup) unsalted butter, melted
  • ¾ cup (150g) granulated sugar
  • 4 large eggs, separated
  • ½ cup (60g) all-purpose flour
  • ⅓ cup (35g) unsweetened cocoa powder
  • 2 cups (480 ml) warm milk
  • 115g (4 oz) dark chocolate (60–70%), melted
  • 1 tsp vanilla extract
  • Pinch of salt

👩‍🍳 Instructions

1️⃣ Prep

Preheat oven to 160°C (320°F).
Grease and line an 8-inch square or round pan.
Place the cake pan into a larger baking dish (for a water bath).

2️⃣ Mix yolk base

Whisk egg yolks and sugar until pale.
Add melted butter and melted chocolate; mix well.
Stir in flour, cocoa powder, salt, and vanilla.
Gradually whisk in warm milk — the batter will be thin.

3️⃣ Whip egg whites

Beat egg whites to soft peaks.
Gently fold into the thin batter in 2–3 additions.
Do not overmix — some streaks are fine.

4️⃣ Bake (Water Bath)

Pour batter into prepared pan.
Add hot water to the outer dish halfway up the sides of the cake pan.
Bake 50–60 minutes.

The center should still have a slight wobble.

5️⃣ Cool

Cool completely in the pan.
Refrigerate at least 2 hours to set the custard layer.


✨ What Makes It Special?

  • The thin batter separates naturally while baking
  • Top layer becomes soft sponge
  • Bottom layer becomes silky chocolate custard
