Ingredients
(Tip: You can find the complete list of ingredients and their measurements in the recipe card below.)
For the Cake:

All-purpose flour

Unsweetened cocoa powder

Baking soda

Salt

Granulated sugar

Vegetable oil

Eggs

Vanilla extract

Sour cream

Hot water or coffee

For the Filling & Frosting (to complete the cake):

Semisweet or dark chocolate chips or chopped chocolate

Heavy cream

Fresh raspberries (for filling and decoration)

Optional powdered sugar or cocoa powder for dusting

Directions
1. Prepare the Cake Batter
Preheat oven to 180 °C (350 °F). Grease and line two 8‑inch round cake pans.

In a large bowl, whisk together flour, cocoa powder, baking soda, and salt.

In another bowl, combine oil, sugar, eggs, vanilla, and sour cream until smooth.

Alternate adding dry ingredients and hot water (or coffee) to the wet, mixing until just combined. The batter will be thin—that’s ideal for a moist texture.

2. Bake the Layers
Divide batter evenly between the prepared pans.

Bake for 25–30 minutes, or until a toothpick comes out with a few moist crumbs.

Let the cakes cool in pans for 10 minutes, then invert onto wire racks to cool completely.

3. Make the Raspberry Truffle Filling (Optional but recommended)
Heat equal parts chocolate and heavy cream in a heatproof bowl until just melted into a ganache.

Gently fold in fresh raspberries and allow to cool until spreadable.

4. Assemble the Cake
Place one cake layer on a serving plate. Spread a generous layer of raspberry truffle filling.

Top with second cake layer. Frost the top or sides with remaining ganache or leave the sides exposed for a “naked” look.

Decorate with fresh raspberries and a dusting of cocoa or powdered sugar.

5. Chill & Serve
Chill for at least 30 minutes to set the frosting before slicing.

Slice carefully and serve—each bite delivers a luxurious blend of dark chocolate and juicy berry flavor.

Servings and Timing
Yield: 8–12 servings

Preparation Time: 20 minutes

Baking Time: 25–30 minutes

Assembly & Decorating: 15 minutes

Chill Time: At least 30 minutes before serving

Total Time: Approximately 1 hour 30 minutes (including cooling)

Variations
Flourless or gluten-free option: Replace flour with almond flour or a gluten-free blend; omit baking soda and reduce moisture slightly.

Raspberry compote swirl: Instead of folding raspberries in ganache, swirl a cooked raspberry compote between layers for visual impact.

Espresso kick: Use hot espresso instead of hot water to intensify chocolate richness.

Nutty crunch: Add chopped toasted hazelnuts or pistachios to the filling or as a garnish.

Storage/Reheating
Storage: Keep covered at room temperature for one day or in the refrigerator (well sealed) for up to 4 days.

Freezing: Freeze individual slices wrapped tightly for up to 2 months. Thaw overnight in the refrigerator.

Serving tip: If refrigerated, allow cake to sit at room temperature for 15–20 minutes before serving for optimal texture.

FAQs
1. Can I replace cocoa powder with melted chocolate in the batter?
Yes. Use 100 g melted dark chocolate and reduce the oil by 2 tablespoons for a richer flavor and fudgier texture.

2. Do I have to use coffee?
No—but using hot coffee enhances the chocolate flavor. Hot water works fine if you prefer a milder taste.

3. Can this be made ahead?
Absolutely. Bake cakes a day in advance, refrigerate, and assemble on the day of serving for easier preparation.

4. How do I get clean slices?
Chill the cake before slicing and use a hot, clean knife wiped between cuts for smooth, neat slices.

5. Can I use frozen raspberries?
Yes—thaw and drain them thoroughly before mixing into ganache to avoid excess liquid.

6. How do I make a dairy-free version?
Use dairy-free cream and dark chocolate, and replace sour cream with coconut yogurt or a non-dairy alternative.

7. Can I skip the truffle filling and just frost the cake?
Yes—spread ganache or buttercream between layers and on top, then add raspberries as garnish.

8. Why is the batter thin?
The hot water (or coffee) thins the batter and activates cocoa, resulting in a deeply moist and tender cake.

9. Can I bake in a single pan?
Yes—bake in a 9×13-inch pan for 35–40 minutes. Cool, then slice into squares to serve.

10. Is the ganache filling stable?
Yes—allow the ganache with raspberries to cool and thicken before spreading to prevent dripping and maintain structure.

Conclusion
The Dark Chocolate Raspberry Truffle Cake is an elegant and indulgent dessert that marries dark chocolate’s intensity with juicy raspberry brightness. Simple to prepare yet show-stopping in appearance, this cake is perfect for celebrations, dessert tables, or any occasion craving a luxurious sweet finish.
