  • 1 pinch of salt

Instructions
 

Base:

  • Preheat oven to 180°C (350°F). Line the bottom of a springform pan (20–23 cm) with parchment paper.
  • Melt chocolate and butter together in a bowl over a bain-marie or microwave (30-sec intervals), stirring until smooth. Let cool slightly.
  • Separate eggs. In a bowl, whisk yolks with sugar until pale and fluffy.
  • Add melted chocolate mixture into the yolks and mix until smooth.
  • Sift in flour and salt. Fold gently to avoid overmixing.
  • Whisk egg whites with a pinch of salt until stiff peaks form.
  • Fold egg whites into the batter gently with a spatula.
  • Pour into the pan and bake for 20–25 min. The center should remain moist. Cool completely before topping with mousse.

Chocolate Mousse:

  • Melt chocolate over bain-marie or in microwave. Let it cool to room temp.
  • Separate eggs. Beat whites with a pinch of salt until stiff peaks form.
  • In another bowl, whisk yolks with sugar until pale and creamy.
  • Add melted chocolate into the yolk mixture. Mix well.
  • Whip cold cream to firm peaks.
  • Fold whipped cream into the chocolate mixture using a spatula.
  • Gently fold in egg whites in batches until smooth and airy.
  • Assembly: Pour mousse over cooled cake base. Smooth the top. Refrigerate for at least 4 hours or overnight until set.

Notes

Decoration & Serving

  • Before serving, garnish with chocolate curls, powdered sugar, or fresh berries.
  • Unmold gently and place on a serving plate. Serve chilled.

💡 Tips to Avoid Common Mistakes

  • Melt chocolate properly to avoid lumps in mousse or base. Stir constantly.
  • Don’t overmix the batter or mousse – it flattens the airiness.
  • Cool the cake base completely before adding mousse.
  • Ensure mousse is set before slicing – refrigerate for minimum 4 hours.
  • Whip egg whites and cream correctly for proper mousse texture.

🧁 Ingredient Alternatives

  • Milk or white chocolate: For a sweeter, milder mousse (adjust sugar).
  • Butter substitute: Use unsweetened applesauce for a lighter cake base.
  • Dairy-free cream: Use coconut or plant-based whipping cream.
  • Gluten-free: Replace flour with almond or rice flour.
  • Egg-free: Use egg substitutes like yogurt, applesauce, or commercial alternatives.

📝 Advanced Tips

  • Use high-quality dark chocolate (70% cocoa or more) for rich flavor.
  • Ensure room-temperature eggs and very cold cream for best results.
  • Use a springform pan or lined mold for easy unmolding.
  • Prepare up to 2 days in advance, store in the fridge, covered.
  • For clean cuts, use a hot knife dipped in warm water and wiped dry.

🍫 Creative Variations & Ideas

  • Add flavors: Try cinnamon, orange zest, or chili for a twist.
  • Serve with sauces: Raspberry or mango coulis pairs beautifully with chocolate.
  • Frozen version: Freeze the cake and serve semi-frozen as a refreshing summer dessert.
  • Mini portions: Use silicone molds or cupcake tins for individual servings.

FAQ

Q1: Can I make it ahead of time?
Yes! Make it up to 2 days ahead. Keep covered and chilled.
Q2: Can I use milk chocolate instead of dark?
Yes, but reduce the sugar slightly as milk chocolate is sweeter.
Q3: Why is my mousse too soft or runny?
Ensure cream is whipped to firm peaks and egg whites are fully stiff.
Q4: Can I freeze the cake?
Yes. Freeze it once mousse is set. Thaw in the fridge before serving.
Q5: My sponge feels dense, what went wrong?
Either overmixed or whites weren’t stiff enough. Fold very gently next time.
Q6: Can I use individual molds?
Absolutely! Adjust baking time for smaller base sizes.
