Ingredient spotlight: chocolate

Chocolate is undoubtedly the star of this recipe. Since it appears in both the sponge cake and the cream topping, its quality plays a major role in the final flavor.

For the best results, choose a dark cooking chocolate containing at least 50% cocoa solids — it provides the perfect balance between sweetness and deep chocolate flavor while also creating a smoother texture.

Here’s everything condensed into one printable card — check off ingredients as you go, and follow the numbered steps in order.

Step-by-step instructions

Step 1: Whisk the eggs and sugar

Place the eggs and sugar in a large mixing bowl. Using an electric mixer, beat them together for several minutes until the mixture becomes pale, fluffy, and almost doubles in volume.

Incorporating air at this stage helps create the soft and airy texture that makes the sponge cake so enjoyable.

Step 2: Add the melted chocolate mixture

Melt the margarine and cooking chocolate together until smooth and glossy. Allow the mixture to cool slightly before slowly pouring it into the whipped egg mixture.

Mix gently until everything is fully incorporated and the batter becomes smooth, silky, and evenly chocolate-colored.

Step 3: Add the dry ingredients

In a separate bowl, combine the flour and baking powder. Gradually fold the dry ingredients into the chocolate mixture until no dry pockets remain.

Avoid overmixing at this stage — gentle folding helps maintain a softer sponge texture while preventing the cake from becoming dense.

Step 4: Prepare the baking pan

Line a baking pan with parchment paper and pour the batter inside. Use a spatula to spread the mixture evenly across the pan for consistent baking.

Step 5: Bake the sponge cake

Place the pan in a preheated oven at 180°C (350°F) and bake for approximately 20 minutes. Begin checking a few minutes early, as oven temperatures can vary — insert a toothpick into the center, and if it comes out clean, the sponge is ready.

Step 6: Prepare the chocolate cream

Pour the sweet cream into a saucepan and heat it over medium heat. Once warm, add the cooking chocolate and stir continuously until completely melted.

The mixture should become smooth, glossy, and free of lumps. Avoid boiling the cream aggressively, as excessive heat can affect the final texture.

Step 7: Soak the sponge cake

While the sponge cake is still warm, use a toothpick or skewer to create small holes across the entire surface. Slowly pour the warm chocolate cream over the cake, allowing it to seep in.

Don’t worry if the cream appears thin at first — during chilling, it will gradually thicken and create a silky finish.

Step 8: Chill and set

Allow the cake to cool completely at room temperature before transferring it to the refrigerator. For best results, chill for at least 4 hours; overnight chilling delivers an even better texture and deeper chocolate flavor.

Step 9: Decorate and serve

Once the cream has fully set, decorate the cake however you like. Popular options include grated chocolate, whipped cream, chopped hazelnuts, walnuts, chocolate curls, or colorful sprinkles.

Slice and serve chilled for the ultimate chocolate experience.

Common mistakes to avoid

What makes this cake so moist?

Unlike many traditional chocolate cakes, this recipe relies on a unique soaking method: small holes are created across the sponge and covered with warm chocolate cream, which gradually penetrates every layer. As the dessert chills, the cream thickens while the sponge becomes softer and richer — resulting in a cake that almost melts in your mouth.

Serving suggestions

Although this cake is delicious on its own, several pairings can elevate the experience even further.

• ☕ Coffee — a perfect pairing
• 🍓 Strawberries — a fresh contrast
• 🍦 Ice cream — extra indulgence
• 🥛 Cold milk — a classic choice

Crushed hazelnuts, chocolate shavings, or whipped cream can also add additional texture and visual appeal.

Storage and freezing guidelines

For best results, store the cake covered in an airtight container inside the refrigerator to preserve both moisture and flavor.

If freezing, wrap individual slices tightly and thaw overnight in the refrigerator before serving.
