Chocolate raspberry cake: simple recipe for an impressive dessert tonight

Glossy chocolate ganache wraps around a tall, multi-layer cake that hides ribbons of raspberry jam and fresh berries between each tier — a dessert that looks dramatic yet slices cleanly when served at room temperature. With entertaining back on many calendars, this cake is both a showpiece and a forgiving build for home bakers who want reliable results.

Why this recipe matters now

Combining dark chocolate and bright raspberries remains a popular pairing for seasonal gatherings and holiday menus. The recipe balances rich, fudgy coating with fresh fruit accents, and it includes practical steps—like a brief chill to set a crumb coat—that help even modestly experienced bakers achieve neat slices and attractive presentation.

• Yield: about 12–16 servings
• Timing: active prep ~1 hour; bake and chill times add another 2–3 hours overall, depending on cooling

Ingredients

Below are the grouped ingredients for the cake, the ganache and the fruit filling. Quantities are listed for three 8-inch layers.

• For the cake

  • 3/4 cup (180 ml) neutral oil (canola or grapeseed), plus extra to grease pans
  • 2 1/4 cups (450 g) granulated sugar
  • 2 cups (256 g) all-purpose flour
  • 1 1/4 cups (110 g) Dutch-process cocoa powder, sifted if clumpy
  • 1 1/2 teaspoons baking powder
  • 1 1/2 teaspoons baking soda
  • 1 1/2 teaspoons kosher salt
  • 1 cup (240 g) sour cream, at room temperature
  • 3 large eggs, room temperature
  • 1 tablespoon pure vanilla extract
  • 1 cup (240 ml) hot brewed coffee

• For the ganache

  • 18 ounces (about 510 g) dark chocolate (65–72%), finely chopped
  • 1 1/2 cups (360 ml) heavy cream
  • 2 teaspoons pure vanilla extract
  • 1/4 teaspoon kosher salt

• For the filling and garnish

  • 6 tablespoons raspberry jam
  • 3 cups (about 360 g) fresh raspberries

Method

Follow these condensed, practical steps. Read through once before you begin so the timing for cooling and chilling is clear.

1. Preheat the oven to 350°F (175°C). Grease and line three 8-inch round pans with parchment.
2. In a large bowl or the bowl of a stand mixer, whisk together the sugar, flour, cocoa, baking powder, baking soda and salt until evenly combined.
3. Whisk the oil, sour cream, eggs and vanilla in a separate measuring cup. Add the wet mix to the dry ingredients and stir on low until moistened, then beat on medium-high for about 2 minutes, scraping the bowl once. Fold in the hot coffee with a flexible spatula — it blooms the cocoa and thins the batter into a glossy consistency.
4. Divide the batter evenly between the pans (roughly 2 cups / 530 g per pan). Tap the pans to release large air pockets and bake 30–40 minutes, until the layers are risen and a toothpick comes out clean. Cool in the pans for 15–20 minutes, then invert onto a rack to finish cooling.
5. While the cakes cool, prepare the ganache: place chopped chocolate, vanilla and salt in a heatproof bowl. Heat the cream to a simmer, pour it over the chocolate and leave for 1–2 minutes. Whisk until glossy and smooth, then chill in the refrigerator, stirring occasionally, until it reaches a spreadable, fudgy texture (about 30 minutes).
6. Trim domed tops from the layers so they stack evenly. Whisk the chilled ganache briefly before using; scrape the bowl sides since the edges set faster than the center.
7. To assemble: place one cake layer (trimmed side up) on a serving plate. Spread about 1/2 cup ganache to form a thin ring toward the edge, creating a small dam, then spoon 1–1/2 tablespoons raspberry jam into that well. Top with roughly 1 cup fresh raspberries pressed into the filling so they sit flat.
8. Repeat with the second layer (trimmed side down) and the same amounts of ganache, jam and raspberries. Add the top layer and press gently to level. If the stack feels unstable, chill briefly so the layers settle.
9. Apply a thin crumb coat of about 1 cup ganache over the top and sides to lock in crumbs. Chill 10–15 minutes until the coating firms.
10. Finish with the remaining ganache, spreading quickly while the cake is cool so the coating smooths evenly. Decorate the top with the remaining raspberries.

Serving and storage

Let the finished cake return to room temperature before slicing — the ganache will soften and give clean cuts. Use a hot, wiped knife for the tidiest slices. Leftovers keep refrigerated for up to three days; bring slices back to room temperature before serving.

Notes and variations

For an easier, less costly finish, swap the ganache for a chocolate buttercream — it’s more forgiving during assembly and still pairs well with raspberry. If you prefer a stronger chocolate flavor, use strong hot coffee in the batter; the coffee amplifies cocoa notes without leaving a coffee taste.

• Tip: If raspberries are large, halve them so they lie flat between layers.
• Chilling briefly between stages (after stacking and after the crumb coat) will make final smoothing simpler and reduce crumbs in the ganache.
