Chocolate lasagna is the ultimate no-bake dessert that looks absolutely stunning and tastes even better! This elegant treat features layers of rich chocolate mousse, creamy mascarpone filling, and crispy wafer cookies that come together in pure chocolate bliss. Perfect for dinner parties or special occasions, this dessert can be made ahead, making it ideal for entertaining.
What makes this chocolate lasagna recipe so special is how it mimics the structure of traditional savory lasagna but transforms it into something decadently sweet. The “noodles” are actually crispy chocolate wafers or thin chocolate cake layers, while the “sauce” becomes luxurious chocolate mousse and silky mascarpone cream. It’s a show-stopping dessert that tastes far more complicated than it actually is.
I love serving this when I want to impress guests without spending hours in the kitchen. The beauty of this recipe is that it can be assembled the day before, allowing the flavors to meld together beautifully. You can customize it with different types of chocolate—dark, milk, or a combination—depending on your preference. Some people like to add a hint of espresso powder to deepen the chocolate flavor, while others prefer to keep it pure.
This chocolate lasagna pairs beautifully with fresh berries, a dollop of whipped cream, or even a scoop of vanilla gelato. For the best results, make sure your ingredients are at room temperature before assembling, and don’t skip the chilling time between layers. The result is a dessert that’s creamy, decadent, and absolutely unforgettable.

Ingredients
- 8 oz semi-sweet or dark chocolate, chopped
- 8 oz heavy whipping cream, divided
- 4 egg yolks (room temperature)
- 3 tablespoons sugar
- 1 teaspoon vanilla extract
- 16 oz mascarpone cheese (room temperature)
- 1/4 cup powdered sugar
- 2 tablespoons unsweetened cocoa powder
- 1 tablespoon espresso powder (optional)
- 24 chocolate wafer cookies or thin ladyfingers
- 1/4 cup coffee or water (for brushing)
- 2 tablespoons coffee liqueur or Kahlúa (optional)
- Pinch of sea salt
- Extra cocoa powder for dusting
- Chocolate shavings for garnish (optional)
Instructions
- Start by preparing your 9×13 inch baking dish by lining it with parchment paper, allowing the paper to overhang the sides for easy removal later.
- Chop the semi-sweet chocolate into small, uniform pieces and place in a heat-safe bowl.
- Heat 4 oz of heavy cream in a saucepan over medium heat until it just begins to steam and small bubbles form around the edges.
- Pour the hot cream over the chopped chocolate and let it sit undisturbed for 2 minutes to allow the residual heat to melt the chocolate.
- Gently stir the chocolate and cream mixture until completely smooth and glossy, then set aside to cool slightly.
- In a separate bowl, whisk together the egg yolks and sugar over a double boiler (or heat-safe bowl over simmering water) for 3-4 minutes until the mixture reaches 160°F on an instant-read thermometer, which pasteurizes the eggs.
- Remove the egg mixture from heat and whisk in the vanilla extract, then fold this mixture into the cooled chocolate ganache until fully combined.
- In another clean bowl, whip the remaining 4 oz of heavy cream to stiff peaks using an electric mixer.
- Gently fold the whipped cream into the chocolate mixture in two additions, being careful not to deflate the cream.
- In a separate bowl, combine the room-temperature mascarpone, powdered sugar, cocoa powder, and espresso powder (if using), whisking until smooth and creamy.
- Mix together the coffee or water with coffee liqueur (if using) in a shallow bowl for brushing the wafers.
- Quickly dip 8 chocolate wafers into the coffee mixture (just 1-2 seconds per side so they don’t become soggy) and arrange them in a single layer at the bottom of your prepared baking dish.
- Spread half of the chocolate mousse mixture evenly over the wafer layer using an offset spatula.
- Repeat the dipping and layering process with 8 more wafers, then spread the entire mascarpone mixture over this layer.
- Create the final layer by dipping the remaining 8 wafers and arranging them on top, then finish with the remaining chocolate mousse spread evenly across the top.
- Cover the lasagna with plastic wrap and refrigerate for at least 4 hours, or preferably overnight, to allow the layers to set and flavors to meld.
- When ready to serve, dust generously with additional cocoa powder and add chocolate shavings if desired.
- To slice, use a hot, wet knife, wiping it clean between each cut for neat, beautiful portions, and serve on chilled dessert plates.
Pro Tips
- This recipe contains raw egg yolks that are pasteurized through heating to 160°F—this step is crucial for food safety and should not be skipped
- If you’re uncomfortable with even pasteurized eggs, you can substitute with 3 tablespoons of pasteurized egg white powder mixed with 3 tablespoons of water
- The mascarpone cheese must be at room temperature before mixing to ensure a smooth, lump-free filling; cold mascarpone will be difficult to whisk
- Chocolate wafers work beautifully, but you can also use thin chocolate cake layers, ladyfingers, or even graham crackers for a different texture
- The coffee or espresso component isn’t just for flavor—it actually enhances and deepens the chocolate taste without making the dessert taste like coffee
- Make sure your baking dish is level before filling to ensure even layers throughout
- This dessert can be made up to 24 hours in advance, making it perfect for entertaining and reducing day-of stress
- For a lighter version, you can use whipped mascarpone mixed with whipped cream instead of the heavier mousse layer
- Storage: Cover with plastic wrap and refrigerate for up to 3 days; do not freeze as the texture will be compromised
- When slicing, dip your knife in hot water and wipe between cuts for clean, beautiful portions that showcase the gorgeous layers
- For extra decadence, serve with a dollop of freshly whipped cream, fresh raspberries, or a scoop of vanilla gelato
- You can customize the sweetness level by adjusting the amount of powdered sugar in the mascarpone mixture
- High-quality chocolate makes a significant difference in this recipe—invest in good chocolate for the best flavor
- This dessert is naturally elegant and requires minimal garnishing, but chocolate shavings or a dusting of cocoa powder adds a professional finishing touch
