Ingredients for Chocolate Raspberry Cake
Here's what you'll need to make these incredible chocolate raspberry cake
For the Chocolate Cake:
- Dutch-processed cocoa powder : This gives the cake its deep, dark color and smooth chocolate flavor without any bitterness.

- Kosher salt (1½ teaspoons): Enhances every other flavor in the batter.
- Baking powder (1 teaspoon): Helps the cake rise evenly.
- Baking soda (½ teaspoon): Works with the cocoa to keep the crumb light.
- Eggs, large (3): Bind the batter and add richness.

- Vegetable oil (1 cup): Keeps the cake ultra-moist, even after chilling.

Instructions for Chocolate Raspberry Cake
Creating that perfect chocolate raspberry cake is easier than you think.
Preheat and prep: Preheat your oven to 325°F convection or 350°F conventional. Grease three 8-inch or 9-inch cake pans and line the bottoms with parchment paper so your layers release cleanly.
Mix your dry ingredients: Sift the cocoa powder, flour, salt, baking powder, and baking soda together into a large bowl. Sifting here keeps the batter lump-free and light.
Build the wet base: In a separate bowl, whisk the eggs and vanilla together until smooth. Slowly drizzle in the oil while whisking continuously this creates a stable emulsion that keeps your cake moist.
Add sugar: Stir in the granulated sugar and whisk until fully incorporated. The batter will start looking glossy.
Combine wet and dry: Alternately add the dry ingredients and milk in three additions, mixing gently until smooth after each one. Don't overmix just combine until no dry streaks remain.
Bake: Divide the batter evenly between your pans. Bake for 25-28 minutes, starting to check at the 20-minute mark. A toothpick inserted in the center should come out clean or with a few moist crumbs.
Cool the layers: Let the cakes cool in the pans for 10 minutes, then flip them onto wire racks to cool completely before assembling.
Make the raspberry jam: Combine raspberries, lemon juice, and sugar in a saucepan over low heat. Stir occasionally as the berries soften, then increase heat to medium and simmer until thickened, about 15-20 minutes. Strain through a sieve into a frozen bowl, pressing well to remove seeds. Refrigerate until cold.
Make the chocolate fudge frosting: Place chopped chocolate, vanilla, corn syrup, and salt in a heatproof bowl. Heat the cream to a boil, pour it over the chocolate, and let it sit for 2 minutes. Whisk until smooth, then sift in the cocoa powder and whisk again. Add butter and stir gently until melted. Let it cool to room temperature — you can stir it every 10 minutes in the fridge to speed this up.
Make the raspberry buttercream: Beat softened butter in a stand mixer until light and fluffy. Gradually add powdered sugar, vanilla, and salt. Add the raspberry jam a little at a time, mixing until smooth and beautifully pink. This is that raspberry ruby chocolate buttercream magic. Adjust consistency with a squeeze of lemon juice or a splash of cream. Transfer one cup to a piping bag for damming.
Assemble: Place your first cake layer on a serving plate. Pipe a ring of buttercream around the edge to act as a dam. Spread raspberry jam inside the ring, then cover with more buttercream. Repeat with the second layer. Add the final layer and refrigerate for 30 minutes to firm everything up.
Frost: Spread chocolate fudge frosting over the top and sides, smoothing with an offset spatula. Refrigerate for another 30 minutes before slicing and serving.
Substitutions for Chocolate Raspberry Cake
You can adjust this recipe while keeping that beautiful chocolate raspberry cake.
- No Dutch-process cocoa? Natural cocoa works but the flavor will be slightly less smooth.
- Dairy-free option: Swap butter for vegan butter and use full-fat coconut milk in place of heavy cream and regular milk.
- Frozen raspberries: Work perfectly in both the jam and buttercream — no need to thaw first.
- Corn syrup in the frosting: Honey is a great 1:1 swap and adds a subtle floral note that complements the raspberry ruby chocolate combination beautifully.
Equipment for Chocolate Raspberry Cake
To achieve that perfect chocolate raspberry cake , you'll want:
- 3 x 8-inch or 9-inch cake pans
- Parchment paper
- Sifter
- Stand mixer or hand mixer
- Whisk
- Silicone spatula
- Piping bag
- Cooling racks
- Offset spatula
Storage Tips for Chocolate Raspberry Cake
Store an unfrosted chocolate raspberry cake at room temperature for up to 3 days, or wrap the layers and freeze for up to 2 months. Once frosted, keep it at room temperature for up to 3 days, covered loosely. If your kitchen runs warm, a quick 15-minute chill before serving keeps the frosting looking sharp. Individual slices with that raspberry ruby chocolate buttercream also freeze beautifully — just wrap tightly in plastic and thaw overnight in the fridge.
Expert Tips for Chocolate Raspberry Cake
Level your cake layers with a serrated knife if they've domed during baking. Flat layers stack more stably and look cleaner after frosting.
Room temperature ingredients matter. Cold butter won't cream properly, and cold eggs can make the batter break. Set everything out an hour ahead.
Don't skip chilling between assembly steps. Those 30-minute rests keep the layers from sliding and make the final frosting much easier to apply smoothly.
Strain that jam. The texture of seedless jam inside the cake is so much more pleasant, and it pipes cleanly with the buttercream.
Taste your chocolate before using it. The quality of your dark chocolate directly affects how good that fudge frosting tastes — and ultimately how well it complements the raspberry ruby chocolate buttercream layers.
FAQ for Chocolate Raspberry Cake
What can I do with melting chocolate?
Melting chocolate is incredibly versatile. You can use it to make ganache, drizzle it over cakes like this one, dip fruit, or create chocolate decorations. For this recipe, melted dark chocolate goes into the fudge frosting and pairs with the raspberry ruby chocolate buttercream for a beautiful finish.
What kind of chocolate should I use for chocolate bombs?
For chocolate bombs, you want a chocolate with good melt-and-snap properties — typically a couverture chocolate with at least 50-60% cocoa solids. The same dark chocolate used in this cake's fudge frosting works wonderfully.
Why is it called death by chocolate?
The term "death by chocolate" refers to desserts that are so intensely chocolatey they feel almost overwhelming in the best possible way. This chocolate raspberry cake definitely flirts with that territory, especially with the Dutch-process cocoa in both the cake and frosting layered with raspberry ruby chocolate buttercream.
How do you make hot chocolate bombs?
Hot chocolate bombs are hollow chocolate shells filled with cocoa mix and marshmallows. You melt chocolate, coat a sphere mold, let it set, fill one half, seal the halves together, and drop the finished bomb into hot milk. For an extra twist, a raspberry ruby chocolate version with white chocolate and freeze-dried raspberry powder inside is stunning.
