• 1 tsp baking powder
• 1/2 tsp baking soda
• 1/4 tsp salt
• 2 large eggs
• 1/2 cup (120ml) buttermilk
• 1/4 cup (60ml) vegetable oil
• 1 tsp vanilla extract
• 1/2 cup (120ml) hot water

Chocolate Mousse

• 1 cup (175g) semi-sweet chocolate chips
• 2 cups (480ml) heavy whipping cream (divided)
• 1/4 cup (50g) granulated sugar
• 1 tsp vanilla extract

Raspberry Layer

• 2 cups (250g) fresh raspberries (plus extra for garnish)
• 1/4 cup (50g) granulated sugar
• 2 tsp cornstarch
• 2 tbsp water

Whipped Topping (Optional)

• 1 cup (240ml) heavy whipping cream
• 2 tbsp powdered sugar
• 1/2 tsp vanilla extract

Step-by-Step Instructions

1. Make the Chocolate Cake Base

1. Preheat your oven to 350°F (175°C) and grease a 9-inch springform pan. Line the bottom with parchment paper.
2. In a large bowl, sift together the flour, sugar, cocoa powder, baking powder, baking soda, and salt.
3. Add the eggs, buttermilk, oil, and vanilla extract to the dry ingredients. Mix until smooth.
4. Gradually stir in the hot water, ensuring the batter is fully combined. It will be thin, which is normal.
5. Pour the batter into the prepared pan and bake for 30–35 minutes or until a toothpick inserted in the center comes out clean.
6. Let the cake cool completely in the pan before removing.

2. Prepare the Raspberry Layer

1. Combine raspberries, sugar, cornstarch, and water in a saucepan over medium heat.
2. Cook while stirring until the raspberries break down and the mixture thickens, about 5–7 minutes.
3. Remove from heat and strain through a fine mesh sieve to remove seeds. Allow the puree to cool completely.

3. Make the Chocolate Mousse

1. Melt the chocolate chips in a microwave-safe bowl in 30-second intervals, stirring between each until smooth. Allow it to cool slightly.
2. In a large bowl, whip 1 1/2 cups of the heavy cream and granulated sugar until stiff peaks form.
3. Gently fold the whipped cream into the melted chocolate in three additions, ensuring a smooth and fluffy mousse.

4. Assemble the Cake

1. Place the cooled chocolate cake layer on a serving platter.
2. Spread the raspberry layer evenly over the top of the cake.
3. Spoon the chocolate mousse over the raspberry layer, smoothing the surface with a spatula.
4. Chill the assembled cake for at least 2 hours to set.

5. Add the Whipped Topping (Optional)

1. Whip the remaining 1 cup of heavy cream with powdered sugar and vanilla extract until soft peaks form.
2. Spread or pipe the whipped topping over the mousse layer.

6. Garnish and Serve

1. Decorate the cake with fresh raspberries and chocolate shavings or curls.
2. Slice and serve chilled for the best texture and flavor.

Ingredient Background

• Raspberries: Fresh raspberries add a natural tartness and vibrant color that beautifully offsets the richness of chocolate. Their seeds are removed in this recipe for a silky finish, but you can keep them for a rustic touch.
• Chocolate: Semi-sweet chocolate chips strike the perfect balance between sweetness and deep chocolate flavor. High-quality chocolate will enhance the dessert significantly.
• Heavy Cream: Used for both the mousse and the optional whipped topping, heavy cream provides the luxurious texture and lightness essential for this cake.
• Buttermilk: This ingredient contributes moisture and a slight tang to the chocolate cake, enhancing its overall richness.

Technique Tips

1. Don’t overmix the mousse: Gently fold the whipped cream into the chocolate to maintain its airy texture. Overmixing can deflate the mousse.
2. Cool components thoroughly: Ensure the cake, raspberry layer, and melted chocolate are fully cooled before assembling to avoid melting the mousse.
3. Use a springform pan: This makes removing the cake much easier and ensures clean edges for the layers.
4. Chill for stability: Allow the cake to chill adequately after assembling for the flavors to meld and the mousse to firm up.

Alternative Presentation Ideas

• Make individual mousse cups by layering pieces of cake, raspberry sauce, and mousse in small glass jars.
• Use a square pan to create mousse cake bars, cutting them into neat squares for serving.
• Create a naked-style cake by omitting the whipped topping and letting the mousse and raspberry layers shine.

Additional Tips for Success

• Use room-temperature eggs for the cake batter to ensure smooth mixing.
• Chill your mixing bowl and beaters before whipping cream for faster and better results.
• Keep extra raspberries and chocolate shavings on hand for garnish—they add an elegant touch.
• If serving at an event, slice the cake with a hot knife for cleaner cuts.

Recipe Variations

• White Chocolate Mousse: Substitute semi-sweet chocolate with white chocolate for a sweeter mousse layer.
• Berry Medley: Use a combination of raspberries, blackberries, and strawberries for the fruit layer.
• Gluten-Free Version: Replace all-purpose flour with a gluten-free baking mix in the cake base.
• Vegan Option: Use dairy-free chocolate, coconut cream, and plant-based whipped cream substitutes.

Freezing and Storage

• To Freeze: Assemble the cake without the whipped topping, wrap tightly in plastic wrap, and freeze for up to 1 month. Thaw in the refrigerator overnight before serving.
• To Store: Refrigerate the cake in an airtight container for up to 3 days.

Healthier Twist Ideas

• Swap sugar with a natural sweetener like maple syrup or coconut sugar.
• Use Greek yogurt in place of some of the heavy cream to reduce fat content.
• Incorporate dark chocolate with 70% cacao for more antioxidants.

Serving Suggestions for Events

• Romantic Dinner: Garnish with heart-shaped chocolate pieces for Valentine’s Day.
• Birthdays: Add birthday candles or edible glitter for a festive touch.
• Holidays: Decorate with powdered sugar “snow” and sugared cranberries for Christmas.

Special Equipment

• Springform pan (9-inch)
• Fine mesh sieve
