How to make a Chocolate Raspberry Cake
Raspberry Sauce - Start by mixing the sugar and cornstarch together in a saucepan. This will help prevent the cornstarch from clumping as you add the wet ingredients.
Add the raspberries, lemon juice, and water to the saucepan and let it come to a boil over medium heat. Boil for 3 minutes until it thickens while stirring constantly.
You can choose to strain out the seeds or leave them in at this point. Get a fine mesh strainer and push the hot sauce through it using a silicone spatula until all that remains in the strainer are the raspberry seeds.
Cover the sauce and place in the fridge to chill.
Homemade Chocolate Cake - I love this chocolate cake recipe because it's so easy to whip up. Start by whisking the melted butter, vegetable oil, and cocoa powder together until smooth. I like to use a large 4-cup liquid measuring cup, but a medium bowl will work too.
Next up, whisk in the buttermilk, sour cream, vanilla extract, and eggs until the eggs are well incorporated.
In a large bowl, whisk together all of the dry ingredients until well combined, and then pour in the liquid ingredients in with the dry ingredients. Whisk until the cake batter is smooth.
Pour into two prepared 8-inch cake pans and bake until the top bounces back when gently touched with your finger or a toothpick inserted into the center of the cake comes out clean or with moist crumbs.
Chocolate Frosting - Once the cake is cooled and you are ready to assemble whip up this chocolate buttercream frosting.
Start by adding the butter, half of the powdered sugar, cocoa powder, vanilla, and half of the heavy cream to a bowl. Beat with a hand mixer or stand mixer on low until most of the powdered sugar is incorporated. Turn the mixer on medium and beat until incorporated.
Add the remaining powdered sugar and heavy cream. Beat on low once again until the powdered sugar is almost completely worked into the frosting. Turn the mixer on medium/high and whip until light and fluffy.
How to make Raspberry Filling
Start by adding sugar and cornstarch to a saucepan, and then mix until combined. Pour in the raspberries, lemon juice, and water. You will want to stir and coat the berries in the cornstarch mixture.
Cook and let the raspberry mixture come to a boil. Then allow it to boil for 3 minutes. Make sure to stir constantly, or it will burn.
Remove from heat, and then let it cool down in the fridge as directed.
Seedless Option - Use a fine-mesh strainer to press the sauce through, to discard all the seeds.
Seeded Option - If you want you are more than welcome to leave the seeds in the sauce. If so, just take the cooled sauce and use it right away, no extra steps needed.
Tips and Tricks
- When making this chocolate cake recipe, always add the liquid to the dry ingredients to avoid the dry ingredients forming lumps in the batter.
- Using a cake leveler or a serrated knife to slice the cakes so they're flat. This is make layering the cakes easier and more steady.
- To fill the cake with the raspberry filling, first create a dam with the chocolate buttercream around the outside edge of the cake. I like to place my frosting in a piping bag fitted with a large tip and make the dam.
- You can skip cutting the two cakes in half and half the raspberry filling recipe to make a 2 layer cake rather than a 4 layer cake.
How to decorate Chocolate Raspberry Cake
I swirled on tall swirls of chocolate frosting with fresh raspberries on top of each swirl.
You could add chocolate drips to the cake by making a ganache and adding it to the chilled cake.
Add crushed up freeze-dried raspberries on top of the cake for flecks of pink.
Your chocolate raspberry cake is best when stored in the refrigerator because of the filling. Just cover well in an airtight container or cake container, and refrigerate for up to 5 days. Slice and serve, and enjoy. The cake may dry out a bit as the days pass once it's cut into. So it is best within the first few days of cutting the cake.
Frequently Asked Questions
If you want to make a shortcut, go right ahead and use a raspberry jam in replace of the raspberry filling. It will change the flavor just a bit, but it should convert easily! Just spread on, and assemble cake.
If you want to freeze your cake, you can place your cake in a freezer friendly container, and then freeze for up to 3 months. If you want you can also grab some aluminum foil or plastic wrap, to double coat the cake. Then place in a container to ensure it doesn't freezer burn. That method, you will mess up the frosting, but it does work on protecting the flavor of the cake best.
Yes! When you add the vanilla extract, feel free to add your favorite raspberry extract. I would start with ½ a teaspoon of extract and add more for more flavor.

Assemble the Cake
- Using a cake leveler or cake knife, cut the cooled chocolate cakes in half.
- Add about ⅓ of the frosting to a piping bag fitted with a Wilton 1M piping tip.
- Swipe a small amount of frosting to the center of the cake plate.
- Place one layer of the cake on a cake plate, cut side down. Gently press down.
- Pipe a ring of frosting around the inside edge of the cake.
- Add ½ cup (a little less if you're using seedless sauce) of raspberry sauce to the center of the cake layer. Spread evenly out with an angled spatula.
- Add the next layer of chocolate cake cut side down and gently press it down until the frosting squishing and the cake layer is even.
- Repeat with adding the frosting, raspberry sauce, and layers of cake until you get to the last layer of chocolate cake.
- Add a big dollop of chocolate frosting on top of the cake. Make sure it's more than you think is needed to frosting the top so it gets pushed over the edges of the cake.
- Using a large angled spatula, begin spreading the frosting out. If you're finding the cake is moving a lot, I use my thumb and index to hold the layer on the opposite side of where my angled spatula is and move the spatula towards my thumb and index finger.
- Once the frosting is smoothed out, add frosting to the sides of the cake and begin smoothing it out evenly.
- For a smoother finish, dip the angled spatula in hot water. Wipe off the water and slowly move it straight up and down along the frosting. Repeat every time you pull the spatula area from the frosting.
- Pipe swirls of frosting on top of the cake with the remaining frosting in the piping bag. You can add more frosting if needed.
