Ingredients You’ll Need

The magic of this Decadent Chocolate Raspberry Cake Recipe lies in the harmony between quality ingredients. Fresh raspberries make all the difference in the filling, while natural cocoa powder provides the perfect chocolate base. Having everything at room temperature ensures smooth mixing and a lighter texture.

• Fresh or Frozen Raspberries: Fresh is fantastic, but frozen works great too—just don’t thaw before using for the filling.
• Cornstarch: This thickens the raspberry filling beautifully without lumps.
• Granulated Sugar: Sweetens both the cake and filling without overpowering the chocolate or raspberry flavors.
• Lemon Juice: Adds a subtle brightness to the raspberry filling, enhancing the fruitiness.
• All-purpose Flour: Use spooned and leveled for accurate measurement and tender cake crumb.
• Unsweetened Natural Cocoa Powder: Essential for that deep chocolate flavor; avoid Dutch-process as it changes acidity.
• Baking Soda and Baking Powder: These leavening agents help the cake rise perfectly fluffy.
• Espresso Powder: Optional but highly recommended—it intensifies the chocolate flavor without making it taste like coffee.
• Vegetable or Melted Coconut Oil: Keeps the cake moist and tender.
• Eggs: At room temperature for better emulsion and smooth batter.
• Full-fat Sour Cream: Adds richness and moisture while balancing acidity.
• Buttermilk: Use for moisture and tender crumb; homemade version works fine too.
• Pure Vanilla Extract: Brings warmth and depth to cake and frosting.
• Hot Water or Black Coffee: Helps bloom cocoa and deepen flavor.
• Mini Semi-sweet Chocolate Chips: Tossed in flour to keep them from sinking in the batter.
• Unsalted Butter: For the rich chocolate buttercream, softened to room temp.
• Confectioners’ Sugar: Essential for smooth, sweet buttercream texture.
• Cocoa Powder (for buttercream): Use natural or Dutch-process depending on your preferred taste.
• Heavy Cream or Milk: Helps achieve the perfect buttercream consistency.
• Salt: A pinch balances sweetness beautifully.
• Semi-sweet or Bittersweet Chocolate: For the ganache—quality baking bars work best.
• Raspberry Liqueur (Optional): Adds a boozy raspberry note to ganache, but can be swapped with cream.

Variations

I love how versatile this Decadent Chocolate Raspberry Cake Recipe is—you can easily customize it to fit your taste or dietary needs. Feel free to experiment with flavors and textures to make it your own!

• Dairy-Free Version: I’ve swapped the sour cream for coconut yogurt and used dairy-free butter for the frosting with great results—rich and moist without the dairy.
• Less Sweet Option: You can reduce the sugar in the cake and filling slightly if you prefer a less sweet dessert; just be mindful that buttercream sweetness balances the whole cake.
• Alternative Fruit Filling: Tried it with blackberry or mixed berries once and it was amazing—just replace raspberries with your favorite berry and keep the same method.
• Mini Cupcakes: I made mini chocolate raspberry cupcakes using this batter and filling, perfect for parties and easier portion control!

How to Make Decadent Chocolate Raspberry Cake Recipe

Step 1: Make That Luscious Raspberry Filling

Start by whisking water and cornstarch together until smooth—that’s your thickening magic. Then add raspberries (straight from the freezer is fine) along with sugar and lemon juice to a saucepan over medium heat. Stir and gently mash the berries as they thaw, then bring to a boil and let simmer for 5 minutes, stirring often. The filling will thicken and smell incredible. Remove from heat and stir in vanilla. Let it cool completely, then refrigerate for at least 4 hours to really let it set and develop flavor. I learned early on that chilling this filling overnight is worth the wait for the best texture.

Step 2: Prepare Your Cake Batter

Preheat your oven to 350°F and prep three 9-inch pans with grease and parchment rounds—I like tearing these from parchment paper and greasing them well for cake release ease. In a big bowl, whisk together your dry ingredients: flour, cocoa powder, sugar, baking soda, baking powder, salt, and espresso powder if you’re using it. In another bowl or your mixer, combine oil, eggs, and sour cream on medium-high until smooth. Stir in buttermilk and vanilla, then mix wet ingredients into dry until just combined. Slowly add your hot water or coffee (this step makes the cocoa bloom beautifully!), then fold in those flour-coated mini chocolate chips. The batter will be thin—that’s perfect. Divide evenly among pans and bake about 24-26 minutes until a toothpick comes out clean.

Step 3: Whip Up the Chocolate Buttercream

While your cakes cool, beat softened butter until creamy and pale, then add confectioners’ sugar, cocoa powder, heavy cream, salt, and vanilla. Start mixing on low to avoid sugar clouds, then go high speed for a full minute for fluffy texture. Taste as you go—you can add an extra pinch of salt for depth. This buttercream is your best friend: it goes under the raspberry filling, forms a piped dam to keep filling in place, and creates the perfect crumb coat layer. Yum!

Step 4: Layer with Love

Place your first cake layer on the plate, spread a thin 1/4 cup buttercream layer, then pipe a thick border around the edge with your buttercream in a piping bag—that way the raspberry filling won’t seep out. Fill the middle with about half of your chilled raspberry filling. Repeat with the second cake layer and remaining filling. Top with the third layer and apply a thin crumb coat all over the cake with the remaining buttercream. Refrigerate this for at least 30 minutes so it sets nicely.

Step 5: Make and Apply That Stunning Chocolate Raspberry Ganache

Chop your chocolate finely and place in a heatproof bowl. Warm heavy cream and raspberry liqueur (if you’re using it) until just simmering, then pour over the chocolate. Let it sit for a couple of minutes, then gently stir until smooth and shiny. Chill the ganache in the fridge for 30 minutes until it thickens for easy spreading. Once your crumb coat is set and ganache perfect, spread it generously on your cake, top with fresh raspberries and mint if you like, and get ready for the compliments!

How to Serve Decadent Chocolate Raspberry Cake Recipe

Garnishes

I always top this cake with a handful of fresh raspberries and a few sprigs of fresh mint—it adds vibrancy and a fresh aroma that contrasts beautifully with the rich chocolate. Sometimes, I dust a little powdered sugar on top for that finishing touch, especially for gatherings.

Side Dishes

Pairing this cake with a scoop of vanilla bean ice cream or a dollop of lightly whipped cream really balances the richness. For an adult twist, a glass of raspberry-infused sparkling water or a rich coffee latte rounds out the dessert beautifully.

Creative Ways to Present

For special occasions, I like to serve this cake on a beautiful cake stand decorated with edible flowers or dusted cocoa powder designs. If you’re feeling extra festive, try adding a drizzle of extra raspberry sauce on the serving plate for a restaurant-style presentation that’s sure to wow guests.

Make Ahead and Storage

Storing Leftovers

I wrap the cake tightly with plastic wrap and store it in a cake carrier in the fridge, which keeps it moist and prevents it from absorbing fridge odors. It stays fresh for up to 5 days, though it rarely lasts that long in my house! Just let it sit out for about 20 minutes before serving to soften the buttercream.

Freezing

If you want to freeze the cake, I recommend baking the layers ahead, wrapping them well, and freezing for up to 3 months. When you’re ready, thaw in the fridge overnight, then assemble and frost. You can also freeze the fully frosted cake, but be sure to thaw it slowly to keep the ganache smooth.

Reheating

This cake is best served at room temperature, so I bring leftovers out of the fridge about 30-45 minutes before serving. Avoid microwaving slices, as that can melt the ganache unevenly. If you want warm bites, I gently warm a small piece on a low setting for a few seconds, but honestly, it’s fantastic just as is.
