How To Make Chocolate Raspberry Cake Step by Step

Prepare the Cake Batter
Whisk the granulated sugar, all-purpose flour, unsweetened cocoa powder, baking soda, baking powder, and salt in a large bowl. Add the eggs, buttermilk, oil, and vanilla extract, then beat until well combined.
Add Boiling Water
Carefully pour the boiling water into the batter and whisk gently by hand. The batter will be thin, but this is the secret to a perfect, moist texture.
Bake the Layers
Divide the batter evenly into two prepared cake pans. Bake at 350°F for 30–35 minutes, or until a toothpick inserted in the center comes out clean.
Make the Raspberry Filling
Combine raspberries, sugar, cornstarch, water, and lemon juice in a saucepan over medium heat. Cook until thickened and bubbly, then cool completely.
Prepare the Chocolate Frosting
Whisk the melted butter and unsweetened cocoa powder together. Alternate adding the powdered sugar and milk, then stir in the vanilla extract until smooth.
Assemble the Cake
Place one cake layer on a stand, spread the cooled raspberry filling over the top, and stack the second layer. Frost the entire cake with the chocolate mixture.
Tips For The Best Chocolate Raspberry Cake
- Cool Completely: Never frost a warm cake, or the butter-based frosting will slide right off.
- Strain the Seeds: For a smoother filling, press your raspberry mixture through a fine-mesh sieve to remove seeds before cooling.
- Don’t Overbake: Check your cakes early; overbaking can lead to a dry texture.
- Level Your Layers: If your cake tops are domed, use a serrated knife to level them for a perfectly flat, professional finish.
- Room Temperature Ingredients: Ensure your eggs and buttermilk are at room temperature to help the batter emulsify correctly.
Variations
- Extra Dark: Use Dutch-processed cocoa for a darker, more intense dark chocolate raspberry cake.
- Gluten-Free: Substitute the flour with a high-quality 1:1 gluten-free baking blend.
- Texture Boost: Fold a half-cup of mini chocolate chips into the batter for extra richness.
- Berry Medley: Replace half the raspberries with blackberries for a sophisticated twist.
Storage Instructions
- Fridge: Keep the frosted cake in an airtight container in the refrigerator for up to 4 days.
- Freezer: Freeze unfrosted layers wrapped in plastic wrap for up to 2 months.
- Reheat: If serving chilled, let a slice sit at room temperature for 15 minutes to allow the frosting to soften.
Serving and Pairing Ideas

- Serve with a tall, cold glass of whole milk for a classic pairing.
- Add a side of fresh, lightly sweetened whipped cream to the plate.
- Enjoy a slice with a cup of hot, unsweetened black coffee to balance the sweetness.
- Top with a handful of extra fresh berries for a burst of color and acidity.
Frequently Asked Questions
Can I make this cake ahead of time?
Yes, the cake layers can be baked and wrapped tightly a day in advance. You can also assemble the entire cake 24 hours before serving, as the flavors often meld together beautifully in the fridge.
Why is my cake batter so thin?
That is exactly how it should be! The boiling water “blooms” the cocoa powder and creates a very thin batter, which is the secret to getting that signature moist, tender crumb in this recipe.
Can I use frozen raspberries for the filling?
Absolutely, frozen raspberries work wonderfully for the filling. Just be sure to cook them slightly longer to account for the extra moisture content released during the thawing process.
How do I get clean slices?
For perfect slices, wipe your knife with a warm, damp cloth between each cut. This prevents the frosting and raspberry filling from dragging across the cake surface.
