For the sponge:

  • 4 eggs 🥚
  • 100 g (½ cup) sugar 🍚
  • 200 g (¾ cup + 2 tbsp) margarine or butter 🧈
  • 100 g (3.5 oz) dark cooking chocolate 🍫
  • 4 tbsp all-purpose flour 🌾
  • 1 tsp baking powder 🥄

For the chocolate cream:

  • 600 ml (2 cups) heavy cream 🥛
  • 400 g (7 oz) dark cooking chocolate 🍫
  • 1 tbsp sugar 🍚

Step-by-Step Instructions

1. Prepare the Sponge Cake

1️⃣ Preheat your oven to 180°C (350°F) and grease 9-inch (23 cm) round springform pan with butter or line the bottom with parchment paper for easy removal. Using a springform pan ensures clean edges and makes it easier to transfer the cake to a serving plate without breaking. If you want an extra smooth release, lightly dust the sides with cocoa powder after greasing.

2️⃣ In a large mixing bowl, whisk the egg yolks with sugar until light and fluffy.

3️⃣ Melt the margarine and chocolate over low heat or in the microwave, stirring occasionally. Once smooth, pour it into the egg mixture and stir well.

4️⃣ Mix the flour and baking powder together in a separate bowl, then gradually add them to the batter, mixing gently.

5️⃣ Whip the egg whites into stiff peaks and carefully fold them into the batter using a spatula (not a mixer) to keep the sponge light and airy.

6️⃣ Pour the batter into the prepared pan and bake for about 20 minutes (or until a toothpick inserted in the center comes out clean).

2. Make the Chocolate Cream

1️⃣ In a saucepan, heat the heavy cream, chocolate, and sugar over low heat, stirring continuously until the chocolate is fully melted and the mixture starts to simmer.

2️⃣ Do not boil—once the chocolate is melted, remove from heat and let it cool slightly.

3. Assemble the Cake

1️⃣ While the sponge is still warm, poke small holes all over it with a fork—this will help the cream absorb better.

2️⃣ Pour the warm chocolate cream evenly over the sponge, making sure it soaks in well. The cream will look runny at first, but don’t worry—after a few hours in the fridge, it will set into a silky, fudgy layer.

3️⃣ Let the cake cool at room temperature for about 30 minutes, then place it in the fridge for at least 3-4 hours (or overnight) to allow the cream to set properly.

Tips for the Best Chocolate Wonder Cake

Don’t skip poking holes in the sponge – This allows the chocolate cream to seep in, making the cake extra moist.
Use high-quality dark chocolate – The richer the chocolate, the better the flavor!
Be patient – The cake tastes best after chilling for several hours.
Customize it – Sprinkle with chocolate shavings, add whipped cream, or top with fresh berries for an extra touch.

How to Serve & Store

Serving Suggestions:

For an elegant presentation, serve Chocolate Wonder cake chilled, allowing the rich ganache to maintain its silky texture. Enhance the visual appeal by topping each slice with fresh strawberries, whipped cream rosettes, or a sprinkle of chocolate shavings.

For extra indulgence, accompany the cake with:
✔ A scoop of vanilla ice cream or a dollop of whipped cream
✔ A drizzle of warm chocolate sauce for an even richer flavor
✔ A dusting of cocoa powder or powdered sugar for a refined touch

This cake pairs beautifully with espresso, cappuccino, or a glass of dessert wine for a luxurious finish to any meal.
