How to Make Chocolate Raspberry Truffle Cake Recipe
Step 1: Prepare the Cake Batter
Start by preheating the oven to 350°F (175°C), then grease and flour two 9-inch round cake pans or use parchment paper to ensure easy cake removal. In a large bowl, whisk together the dry ingredients including flour, sugar, baking soda, baking powder, salt, and cocoa powder. Next, add the eggs, buttermilk, vegetable oil, and vanilla extract, mixing until smooth. Slowly incorporate the boiling water, which will make your batter wonderfully thin but yields a moist cake. Finally, stir in sour cream for added richness and tenderness.
Step 2: Bake the Cake Layers
Divide the batter evenly between the prepared pans, then pop them into the oven. Bake for about 30 to 35 minutes. A toothpick inserted into the center should come out clean when done. Let the cakes cool for 10 minutes in the pans before transferring to a wire rack to cool completely. This method keeps your cakes moist and ready for assembling.
Step 3: Make the Raspberry Truffle Filling
While your cakes cool, prepare the luscious filling. Heat heavy cream and butter together in a small saucepan until just simmering. Remove from heat and stir in chopped chocolate until silky smooth. Then fold in the raspberry puree and vanilla extract. Taste and add a little sugar if you prefer a sweeter filling. Let it cool to room temperature before chilling it in the fridge for about 30 minutes so it thickens to the perfect spreadable consistency.
Step 4: Prepare the Chocolate Ganache
Next, prepare the ganache by heating heavy cream in a small pan until it nearly simmers. Remove from heat, add chopped chocolate, stirring until smooth and glossy. Stir in butter for that added richness. Allow the ganache to cool slightly so it thickens just enough to coat but remains pourable.
Step 5: Assemble the Cake
Once your cake layers have cooled, slice each horizontally to create four equal layers. Place the first layer on your serving platter or cake stand, then spread a generous amount of raspberry truffle filling on top. Add the second layer and repeat, ensuring each layer gets that decadent filling. After stacking all layers, pour the chocolate ganache evenly over the top and sides. Smooth it out with a spatula for that elegant, shiny finish.
Step 6: Garnish and Chill
Top the cake with fresh raspberries and dust lightly with powdered sugar if you like. Let your masterpiece sit for at least 30 minutes, giving the ganache time to set beautifully before slicing and serving.
How to Serve Chocolate Raspberry Truffle Cake Recipe

Garnishes
Fresh raspberries are not only the perfect complement to the flavor profile but also add a burst of color and freshness to the cake. A light dusting of powdered sugar enhances its elegance, making it irresistible at first glance. You can also add a few mint leaves for a pop of green and a subtle aromatic lift.
Side Dishes
This Chocolate Raspberry Truffle Cake Recipe is rich, so consider pairing it with lightly sweetened whipped cream or a scoop of vanilla ice cream. Fresh berries or a raspberry coulis also make excellent companions, balancing the deep chocolate flavors with bright fruitiness.
Creative Ways to Present
For a stunning presentation, serve individual slices on delicate dessert plates with a drizzle of raspberry sauce around the edges. You can also decorate the serving platter with whole raspberries and edible flowers. If you’re hosting a party, create mini versions in ramekins or jars, layering the cake and filling for an elegant and portable treat.
Make Ahead and Storage
Storing Leftovers
You can store leftover cake in an airtight container in the refrigerator for up to 4 days. Keeping it chilled preserves freshness and maintains the filling and ganache’s texture perfectly. Be sure to bring it back to room temperature before serving for the best flavor experience.
Freezing
This cake freezes well, making it a great choice for advance preparation. Wrap the cake tightly in plastic wrap and then aluminum foil to prevent freezer burn. Freeze for up to 2 months. When ready to enjoy, thaw overnight in the refrigerator and allow it to come to room temperature before serving.
Reheating
Since this is a delicate truffle cake, reheating is not recommended, as it may affect the texture of the ganache and filling. Instead, simply let chilled slices sit at room temperature for 20–30 minutes to soften slightly before serving.
FAQs
Can I use frozen raspberries for the puree?
Absolutely. Frozen raspberries work well if fresh aren’t available. Just thaw and strain them to remove excess liquid before making the puree to keep your filling from becoming too watery.
Is there a way to make this cake dairy-free?
Yes, you can substitute dairy ingredients with plant-based alternatives like coconut cream for heavy cream, vegan butter, and dairy-free yogurt instead of sour cream. Keep in mind this may slightly change the texture and flavor but the essence of the Chocolate Raspberry Truffle Cake Recipe will remain delightful.
Can I prepare parts of this cake in advance?
Definitely! The cake layers can be baked a day ahead and stored wrapped tightly at room temperature or in the refrigerator. The truffle filling and ganache can be made in advance and refrigerated. Assemble the cake just before serving for the freshest results.
What type of chocolate is best for the ganache and filling?
Use good-quality semisweet or bittersweet chocolate with at least 60% cocoa content. It ensures a rich, balanced flavor that is not overly sweet while complementing the tartness of the raspberry beautifully.
How do I slice the cake cleanly?
Use a sharp knife and wipe it clean between cuts for neat slices. For extra precision, chill the cake for 30 minutes before slicing. Room-temperature knives cut best for the ganache coating but keeping the cake slightly firm helps avoid smudging.
Final Thoughts
This Chocolate Raspberry Truffle Cake Recipe is truly one of those desserts that feels like a loving hug in cake form. The balance of rich chocolate with vibrant raspberry and smooth textures makes it an outstanding choice whenever you want to impress or simply indulge. I can’t wait for you to try it and experience that incredible blend of flavors and textures yourself!

For the Ganache:
- 6 oz semisweet or bittersweet chocolate, chopped
- ½ cup heavy cream
- 1 tablespoon butter
For Garnish:
- 1 cup fresh raspberries
- Powdered sugar (optional, for dusting)
Instructions
- Prepare the Cake: Preheat your oven to 350°F (175°C). Grease and flour two 9-inch round cake pans or line the bottoms with parchment paper to prevent sticking.
- Mix Dry Ingredients: In a large mixing bowl, whisk together the all-purpose flour, granulated sugar, baking soda, baking powder, salt, and unsweetened cocoa powder until evenly combined.
- Add Wet Ingredients: Add the eggs, buttermilk, vegetable oil, and vanilla extract to the dry ingredients. Mix thoroughly until the batter is smooth and uniform.
- Incorporate Boiling Water: Gradually pour in the boiling water, mixing continuously. The batter will be thin, which is expected and ensures a moist cake.
- Fold in Sour Cream: Stir the sour cream gently into the batter for extra richness, then divide the batter evenly between the two prepared cake pans.
- Bake the Cakes: Place pans in the preheated oven and bake for 30-35 minutes. Check for doneness by inserting a toothpick in the center— it should come out clean. Let cakes cool in the pans for 10 minutes, then transfer to a wire rack to cool completely.
- Make Raspberry Truffle Filling: In a small saucepan, heat the heavy cream and butter over medium heat until simmering, then remove from heat. Add chopped chocolate and stir until smooth. Mix in raspberry puree and vanilla extract. Taste the filling and add sugar if desired to sweeten. Cool to room temperature, then refrigerate for about 30 minutes to thicken.
- Prepare Ganache: Heat the heavy cream in a small saucepan until it just begins to simmer, then remove from heat. Stir in the chopped chocolate until smooth and glossy, then add butter and stir to combine. Set aside to cool slightly.
- Assemble the Cake: Once cakes are completely cooled, slice each cake horizontally to create four thin layers. Place the first layer on a serving platter or cake stand.
- Layer with Filling: Spread a generous amount of raspberry truffle filling over the first cake layer. Repeat layering with remaining cake layers and filling until all layers are stacked.
- Apply Ganache: Pour the ganache over the top layer, using a spatula to spread it evenly over the top and sides of the cake for a smooth, glossy finish.
- Garnish: Decorate the cake with fresh raspberries arranged on top. Optionally, dust lightly with powdered sugar for an elegant look.
- Set and Serve: Allow the cake to rest for 30 minutes so that the ganache sets properly. Slice and serve to enjoy the rich, velvety chocolate and raspberry truffle flavors.
Notes
- For the raspberry puree, fresh raspberries are best, but frozen can be used if thawed and strained to remove seeds.
- Be careful not to overbake the cakes to maintain moistness.
- The boiling water helps to bloom the cocoa and create a more intense chocolate flavor in the cake.
- Refrigerate the truffle filling to help it thicken, making it easier to spread between cake layers.
- Use high-quality semisweet or bittersweet chocolate for better flavor in both filling and ganache.
- Allow the ganache to cool slightly before pouring to avoid melting the filling layers.
- Powdered sugar garnish is optional but adds a professional touch for presentation.
