Ingredients Breakdown (with Substitutions & Expert Notes)
1. Chocolate Cake Base
- All-purpose flour – 1 cup (120 g)
- Unsweetened cocoa powder – ½ cup (50 g)
- Baking powder – 1 ½ tsp
- Baking soda – ½ tsp
- Salt – ¼ tsp
- Sugar – ¾ cup (150 g)
- Eggs – 2 large (room temperature)
- Milk – ½ cup (120 ml)
- Hot coffee – ½ cup (120 ml) (enhances chocolate flavor, but water works too)
- Vegetable oil – ⅓ cup (80 ml)
- Vanilla extract – 1 tsp
Substitutions:
- Use a gluten-free flour blend for a gluten-free cake.
- Replace eggs with flax eggs or unsweetened applesauce for a vegan version.
- Swap sugar for monk fruit sweetener or erythritol for a reduced-sugar cake.
2. Raspberry Jelly Layer
- Fresh or frozen raspberries – 2 cups (250 g)
- Sugar – 2–3 tbsp (adjust to sweetness)
- Lemon juice – 1 tsp (boosts tartness)
- Gelatin – 1 tsp (3 g) OR agar-agar powder for vegetarian option
3. Chocolate Mousse
- Heavy cream – 1 ½ cups (360 ml) (chilled)
- Dark chocolate – 1 cup (170 g) (melted & cooled to lukewarm)
- Powdered sugar – 2 tbsp (optional, for sweetness)
- Vanilla extract – 1 tsp
Pro Tip: The mousse depends on proper chocolate cooling—if it’s too hot, it will melt the whipped cream, and if it’s too cold, it will clump. Aim for just slightly warm to the touch.
4. Chocolate Ganache

- Heavy cream – ½ cup (120 ml)
- Butter – 1 tbsp (for extra shine, optional)

Step-by-Step Instructions (Continued)
Step 2: Prepare the Raspberry Jelly Layer
- In a saucepan, combine raspberries, sugar, and lemon juice. Cook over medium heat until the berries break down into a sauce (about 5–7 minutes).
- Strain the mixture through a fine mesh sieve to remove seeds if desired. Return the smooth puree to the pan.
- Sprinkle gelatin (or agar-agar) over 2 tablespoons of cold water. Let it bloom for 5 minutes.
- Stir the bloomed gelatin into the warm raspberry puree until fully dissolved.
- Pour the mixture into a shallow dish and refrigerate until set (about 30 minutes).
Pro Tip: If using agar-agar, the jelly will set much faster and firmer than gelatin. Adjust according to your preference.
Step 3: Make the Chocolate Mousse
- Melt the dark chocolate in a heatproof bowl over simmering water (double boiler) or in the microwave in 30-second bursts. Stir until smooth. Let it cool until just lukewarm.
- In a chilled mixing bowl, whip heavy cream until soft peaks form. Add powdered sugar and vanilla extract, then whip to stiff peaks.
- Fold about one-third of the whipped cream into the cooled chocolate to lighten it. Then gently fold in the remaining cream until smooth and airy.
- Refrigerate until ready to assemble.
Step 4: Prepare the Chocolate Ganache
- Heat cream in a small saucepan until it begins to simmer (do not boil).
- Pour over the chopped chocolate and let sit for 2–3 minutes.
- Stir gently until smooth and glossy. Add butter for an extra silky shine if desired.
- Let cool slightly before pouring over the cake.
Step 5: Assemble the Cake
- Slice the cooled chocolate cake into two even layers.
- Place one cake layer on a serving platter. Spread a generous layer of mousse evenly on top.
- Gently spoon raspberry jelly over the mousse.
- Place the second cake layer on top and repeat with mousse and raspberry jelly if you prefer more layers.
- Cover the entire cake with the remaining mousse, smoothing the top and sides.
- Pour the cooled ganache over the cake, letting it drip down the sides for a beautiful finish.
- Garnish with fresh raspberries, chocolate shavings, or mint leaves.
- Refrigerate for at least 2 hours before serving to allow the layers to set.
Tips for Success
- Temperature Matters: Always allow melted chocolate to cool before adding to whipped cream, or the mousse will collapse.
- Flat Cake Layers: Use a serrated knife to trim the top of the cake for even stacking.
- Clean Slices: Run a sharp knife under hot water, dry it, and then cut the cake for neat slices.
- Layer Stability: Chill each mousse layer for 15 minutes before adding jelly to avoid sinking.
- Presentation Upgrade: Use a springform pan lined with acetate sheets when assembling for sharp, professional edges.
Variations of Heavenly Raspberry Chocolate Mousse Cake
- Triple Chocolate Version – Add layers of white chocolate mousse and milk chocolate mousse along with the dark chocolate for a trio effect.
- Berry Medley – Substitute raspberries with strawberries, blueberries, or blackberries, or use a mix for a vibrant fruit layer.
- Nutty Twist – Add chopped hazelnuts or almonds between layers for crunch.
- Coffee-Infused – Stir a teaspoon of espresso powder into the mousse for mocha lovers.
- Holiday Edition – Garnish with sugared cranberries and rosemary sprigs for a festive winter cake.
- Mini Versions – Assemble the mousse cake in individual dessert cups or glasses for party-ready servings.
Storage and Freezing Guide
- Refrigerator: Store the cake in an airtight container for up to 3 days.
- Freezer: Slice into portions, wrap tightly in plastic wrap, then foil, and freeze for up to 1 month. Thaw overnight in the refrigerator before serving.
- Make-Ahead Tip: You can bake the cake base 1–2 days ahead and store it wrapped at room temperature. Prepare mousse and jelly layers the day before assembly for stress-free baking.
Serving Suggestions
- Serve with a dusting of cocoa powder and extra berries on the side.
- Pair with a dollop of lightly sweetened whipped cream for extra creaminess.
- Add a drizzle of raspberry coulis on the plate for restaurant-style presentation.
- Serve with coffee, champagne, or dessert wine for a luxurious pairing.

Frequently Asked Questions
Q: Can I make this cake gluten-free?
Yes, substitute the flour in the chocolate cake with a gluten-free baking blend. Everything else in the recipe is naturally gluten-free.
Q: Can I use frozen raspberries?
Absolutely! Just thaw them first and drain excess liquid before making the jelly.
Q: Is gelatin necessary?
Gelatin helps the jelly set. For a vegetarian option, agar-agar powder works well.
Q: How far in advance can I make this cake?
You can make it 1–2 days ahead. Just keep it refrigerated until ready to serve.
Q: Can I skip the ganache?
Yes, but ganache gives a glossy finish and locks in moisture. Alternatively, dust with cocoa powder or powdered sugar.
Q: How do I prevent mousse from deflating?
Whip cream to stiff peaks and gently fold it into cooled chocolate without overmixing.
Q: Can kids enjoy this cake?
Yes! The coffee in the cake base can be replaced with hot water, and the alcohol-free version is kid-friendly.
Common Mistakes to Avoid
- Overheating Chocolate: Can cause seizing or grainy texture. Always melt gently.
- Adding Hot Chocolate to Cream: Will melt the whipped cream—let it cool slightly first.
- Skipping Chill Time: Each layer needs time to set for neat slices.
- Using Low-Quality Chocolate: Flavor heavily depends on good chocolate (60–70% cocoa is ideal).
