Ingredients You’ll Need
You won’t believe how a handful of classic pantry staples and a couple of fresh ingredients can fuse into something so decadent! Each one serves its own delightful role, from fudgy texture to vibrant tartness—so don’t skip or skimp.
- All-purpose flour: The backbone of the cake, providing essential structure and softness.
- Unsweetened cocoa powder: For that deep, dark chocolate flavor; be sure to use a good-quality cocoa here.
- Baking soda: Ensures the cake rises beautifully and achieves a light crumb.
- Salt: Balances the sweetness and sharpens all the other flavors.
- Unsalted butter (softened): Adds richness and helps create a tender, moist bite.
- Granulated sugar: Sweetens the cake and lends a little caramelization as it bakes.
- Eggs: Bind everything together and keep the cake light and airy.
- Vanilla extract: Enhances the overall depth and aroma—pure vanilla works wonders here.
- Sour cream: Brings tang and creates an ultra-moist, plush crumb.
- Hot water: Helps the cocoa “bloom” for intensified chocolate flavor.
- Fresh raspberries: The juicy bursts of tartness make each slice special; use ripe, plump berries for best results.
- Semi-sweet chocolate (chopped): Key for a luscious, truffle-like ganache layer on top.
- Heavy cream: Blends with chocolate for that glossy, smooth ganache finish.
- Additional fresh raspberries (for garnish): Jewel-toned and eye-catching, these bring a pop of color.
- Chocolate shavings (optional): For a little elegant touch and extra chocolatey goodness.
How to Make Chocolate Raspberry Truffle Cake
Step 1: Prep Your Pan and Preheat
Set yourself up for cake success by preheating your oven to 350°F (175°C) and preparing your 8-inch round cake pan. Grease it well and line the bottom with parchment paper—this step is a lifesaver for flawless cake release!
Step 2: Sift the Dry Ingredients
In a medium bowl, sift together your flour, cocoa powder, baking soda, and salt. Sifting is the secret to a light, lump-free cake, and helps blend everything evenly. It’ll give your Chocolate Raspberry Truffle Cake that irresistible texture.
Step 3: Cream the Butter and Sugar
In a large bowl, cream the softened butter with the sugar until the mixture is light and fluffy. This step introduces air, ensuring your cake comes out tender and not dense. Once creamy, add the eggs one at a time, mixing fully between each. Stir in the vanilla extract and the decadent sour cream for pillows of richness.
Step 4: Combine and Mix
Gradually add your sifted dry ingredients into the wet mixture, alternating with the hot water. Start and finish with the dry mixture. Stir gently after each addition, just until no streaks remain—overmixing leads to a tougher cake, so be gentle!
Step 5: Fold in the Raspberries
Switch to a spatula and carefully fold in the fresh raspberries. Be delicate here so the berries stay as whole as possible; they’ll burst in the oven and create gorgeous pockets of juice throughout the Chocolate Raspberry Truffle Cake.
Step 6: Bake the Cake
Pour your batter evenly into the prepared pan, smoothing the top. Bake for 30–35 minutes, or until a toothpick inserted into the center comes out clean or with just a few moist crumbs. Let it cool in the pan for about 10 minutes before turning onto a wire rack to finish cooling completely.
Step 7: Make the Ganache Truffle Layer
For that luxurious finish, heat the heavy cream in a small saucepan just until simmering, then pour it over your chopped semi-sweet chocolate in a separate bowl. Let it stand for 2 minutes (no stirring yet!), then whisk together until silky smooth. Let it cool slightly so it thickens but is still pourable—it should be like liquid velvet!
Step 8: Assemble and Garnish
Spread the ganache over your cooled cake, smoothing it with a spatula for that professional look. Decorate generously with fresh raspberries (and a flourish of chocolate shavings if your heart desires). Chill the cake for at least 1 hour so the truffle ganache sets and every slice comes out picture-perfect.
How to Serve Chocolate Raspberry Truffle Cake

Garnishes
This cake loves an extra flourish! Beyond fresh raspberries and chocolate shavings, you can dust on a little powdered sugar or add a sprig of fresh mint for a lovely fresh contrast. A drizzle of raspberry coulis also adds drama and tartness for those who love a plated dessert.
Side Dishes
Serve this stunning Chocolate Raspberry Truffle Cake with a dollop of softly whipped cream or a scoop of vanilla bean ice cream. Pairing it with hot coffee, espresso, or even a glass of sparkling wine instantly elevates it into a true celebration.
Creative Ways to Present
For special occasions, try slicing the cake into petite squares for a truffle-style dessert platter, or bake the batter as cupcakes and top each with a generous spoonful of ganache and a single raspberry. Layer slices with extra whipped cream and berries for a gorgeous layered parfait in a glass—your guests will swoon!
Make Ahead and Storage
Storing Leftovers
If (by some miracle) you have leftovers, store them in an airtight container in the refrigerator. The cake stays moist for up to four days, and the flavors often deepen and improve as they meld together.
Freezing
Chocolate Raspberry Truffle Cake actually freezes beautifully! Simply wrap individual slices tightly in plastic wrap and store in a freezer-safe bag. Thaw overnight in the fridge when ready to enjoy—just add fresh raspberries before serving for best flavor and appearance.
Reheating
If you prefer your cake slightly warm, pop a slice in the microwave for 10–15 seconds. This will soften the ganache and make each bite taste absolutely luscious, almost truffle-like straight from the oven.
FAQs
Can I use frozen raspberries in this cake?
Absolutely! If using frozen raspberries, don’t thaw them—fold them in straight from the freezer to prevent excess moisture from seeping into the batter. This keeps your cake’s texture intact and bakes up beautifully.
Is there a way to make this cake gluten-free?
You can easily swap the all-purpose flour for your favorite 1:1 gluten-free baking blend. Be sure to check that all other ingredients are gluten-free as well, and your results will be just as soft and delicious.
What kind of chocolate works best for the ganache layer?
Semi-sweet chocolate is ideal, as it balances richness with a touch of sweetness, but you can experiment with dark chocolate for a more intense, less sweet flavor. Just be sure to use high-quality chocolate for perfect smoothness and shine.
Can I make the Chocolate Raspberry Truffle Cake a day in advance?
Yes! In fact, the flavors develop even more when the cake sits overnight in the fridge. Just add the fresh raspberry garnish right before serving for the freshest look and taste.
How can I make the cake even richer?
If you want to go all-out, double the ganache and use half to fill the cake if you decide to slice it into two layers. You can also spread a thin layer of raspberry preserves between the cake and the ganache or within the cake for an extra burst of fruitiness.
