Chocolate Raspberry Cake is the kind of recipe I make when I want chocolate to be the main point, not a quiet background note. I make it the way I would talk someone through it across my own counter: what I measure carefully, what I do not rush, and where the texture can go wrong if I get distracted.
I measure the amounts carefully because the balance matters here. When an ingredient seems minor, I still give it its place; chocolate recipes have a way of showing every shortcut.
What I like about chocolate raspberry cake is that it gives a clear payoff for the work. Some steps are quick, some need patience, but none of them are there just to make the recipe look longer.
Why I keep coming back to this
- I can taste the main chocolate flavor clearly instead of just sweetness.
- The quantities are specific enough that I do not have to guess in the middle of cooking.
- I can make parts of it ahead when the recipe needs chilling or cooling.
- The texture gives me a useful cue: set edges, glossy chocolate, thick filling, or a clean skewer.
- The recipe is flexible enough for small variations without losing its identity.
- I like that leftovers store predictably when I cool and cover them properly.

How I make it
Step 1 — I follow this part with a
I follow this part with a little attention: Whisk the cornstarch and water together until all the cornstarch has dissolved. (I just use a fork to mix—very easy.) Combine cornstarch mixture, raspberries (no need to thaw if using frozen), granulated sugar, and lemon juice in a medium saucepan set over medium heat. Using a.
Step 2 — I follow this part with a
I follow this part with a little attention: Allow the raspberry filling to cool at room temperature for 10-15 minutes, then transfer it to a bowl or container and place it in the refrigerator for at least 4 hours and up to 1 week (the longer, the better). No need to cover it, but.
Step 3 — preheat and prepare
I follow this part with a little attention: Preheat oven to 350°F (177°C). Grease three 9-inch cake pans, line with parchment paper rounds, then grease the parchment paper. Parchment paper helps the cakes seamlessly release from the pans..).
Step 4 — I follow this part with a
I follow this part with a little attention: Whisk the flour, cocoa powder, sugar, baking soda, baking powder, salt, and espresso powder (if using) together in a large bowl. Set aside. Using a handheld or stand mixer fitted with a whisk attachment (or you can use a whisk), mix the oil, eggs, and sour.
Step 5 — bake and check
I follow this part with a little attention: Divide batter evenly between 3 pans. Bake for approximately 24-26 minutes. Baking times vary, so keep an eye on yours. The cakes are done when a toothpick inserted in the center comes out clean..
Step 6 — I follow this part with a
I follow this part with a little attention: Remove the cakes from the oven and set on a wire rack. Allow to cool completely in the pan. The cakes may slightly sink in the middle as they cool—that’s expected..
Step 7 — I follow this part with a
I follow this part with a little attention: With a handheld or stand mixer fitted with a paddle or whisk attachment, beat the butter on medium speed until creamy, about 2 minutes. Add confectioners’ sugar, cocoa powder, heavy cream, salt, and vanilla extract. Beat on low speed for 30 seconds, then increase to high.
Step 8 — I follow this part with a
I follow this part with a little attention: Place 1 cooled cake layer on your cake stand or serving plate. Using a large icing spatula or small offset spatula, evenly cover the top with about 1/4 cup of chocolate buttercream frosting (a thin layer). Spoon about 1/2 cup of the chocolate buttercream into a.
Step 9 — I follow this part with a
I follow this part with a little attention: Using the remaining chocolate buttercream, spread a thin layer of buttercream on the top and around the sides as a crumb coat. Run a bench scraper around the cake to smooth out crumb coat. Chill uncovered in the refrigerator for at least 30 minutes and up.
Step 10 — I follow this part with a
I follow this part with a little attention: Place finely chopped chocolate in a medium heat-proof bowl. Heat the cream and raspberry liqueur, if using, in a small saucepan over medium heat until it begins to gently simmer. (Do not let it come to a rapid boil—that’s too hot!) Pour over chocolate, then let.
Step 11 — I follow this part with a
I follow this part with a little attention: Pour/spoon thickened ganache on chilled cake, and spread all over cake with an icing spatula. Garnish with fresh raspberries, if desired. Serve cake immediately or chill, uncovered, for up to 4-6 hours before serving. Cake can be served at room temperature or chilled..

I follow this part with a little attention: Cover leftover cake tightly and store in the refrigerator for 5 days. I like using a cake carrier for storing and transporting..
Tips from my kitchen
- Read the full recipe first.I do this before starting because several chocolate recipes move quickly once heat is involved.
- Measure before mixing.Small amounts like salt, extract, cocoa, and leavening change the final flavor more than they look like they will.
- Watch texture, not just time.I use the clock as a guide, but I trust visual cues more.
- Let it cool when the recipe says to cool.Warm chocolate, warm cake layers, or warm bars can undo careful work.
- Use an oven thermometer if bakes run odd.A few degrees can change chocolate cakes and cookies quickly.
Variations I have actually tried
- Darker chocolate:I use bittersweet chocolate when I want less sweetness and a stronger cocoa edge.
- Salted finish:A few flakes of salt on top make the chocolate taste deeper.
- Nut swap:When nuts are part of the recipe, I keep the same amount and swap only for a similar chopped nut or butter.
- Fruit note:Raspberries, strawberries, banana, or orange zest can brighten rich chocolate if the base recipe suits it.
- Mini portions:I make smaller pieces for trays, but I start checking doneness earlier.
Storing and making ahead
I cool everything completely before storing. Trapped warmth creates condensation, and condensation is how crisp edges soften, chocolate blooms, and bars get sticky.
For make-ahead planning, I separate the components when possible: cake layers wrapped on their own, fillings chilled in a bowl, or candies stored between sheets of parchment. It makes serving day calmer.
How I like to serve it
I serve chocolate raspberry cake in the portion size listed in the recipe card, then let the texture decide the temperature. Creamy desserts taste best cold, cakes taste better after a short sit at room temperature, and crisp snacks need an airtight container until the last minute.
If I am serving this with other desserts, I keep the plate simple. Chocolate already brings plenty of flavor, so coffee, milk, berries, whipped cream, or a salty crunch is usually enough.
Frequently asked questions
Can I make this ahead?
Yes, and I often do. I follow the cooling or chilling cues in the recipe, then store it covered so the texture stays close to freshly made.
Can I change the chocolate?
Usually yes, as long as I use the same amount and a chocolate I like eating. Very sweet chocolate makes the final recipe sweeter, while bittersweet chocolate makes it more intense.
What is the most common mistake?
Rushing the rest time is the mistake I see most. Chocolate and baked goods need time to set, cool, or firm up before they cut, dip, or stack neatly.
How do I know it is done?
I look for the cue in the instructions: set edges, a clean skewer, a thickened filling, a dry macaron shell, or chocolate that has fully set. The timer gets me close, but the cue decides.
Can I freeze it?
Many chocolate cakes, bars, and candies freeze well when wrapped tightly. Creamy mousse and some fresh garnishes do not thaw as nicely, so I freeze only the sturdy parts.
If you make chocolate raspberry cake, I would genuinely like to know which variation you tried and what texture cue helped you most.
Chocolate Raspberry Cake
Description
Chocolate Raspberry Cake is built around water, cornstarch, raspberries, granulated sugar. I walk through the texture cues, storage, variations, and troubleshooting I rely on so the recipe comes out consistently in a home kitchen.
Ingredients You’ll Need
Instructions
- Whisk the cornstarch and water together until all the cornstarch has dissolved. (I just use a fork to mix—very easy.) Combine cornstarch mixture, raspberries (no need to thaw if using frozen), granulated sugar, and lemon juice in a medium saucepan set over medium heat. Using a silicone spatula, stir the mixture, mashing the raspberries as they begin to thaw and soften. Bring to a boil and let it boil for 5 full minutes, stirring occasionally. Remove pan from heat and stir in vanilla extract.
- Allow the raspberry filling to cool at room temperature for 10-15 minutes, then transfer it to a bowl or container and place it in the refrigerator for at least 4 hours and up to 1 week (the longer, the better). No need to cover it, but if refrigerating for longer than 4 hours, cover tightly. It will continue to thicken up as it chills. Raspberry filling must be completely chilled before using in your cake. If freezing, see Note below for instructions.
- Preheat oven to 350°F (177°C). Grease three 9-inch cake pans, line with parchment paper rounds, then grease the parchment paper. Parchment paper helps the cakes seamlessly release from the pans..).
- Whisk the flour, cocoa powder, sugar, baking soda, baking powder, salt, and espresso powder (if using) together in a large bowl. Set aside. Using a handheld or stand mixer fitted with a whisk attachment (or you can use a whisk), mix the oil, eggs, and sour cream together on medium-high speed until combined. Add the buttermilk and vanilla and beat until combined. Pour the wet ingredients into the dry ingredients, add the hot water/coffee, and whisk or beat on low speed until the batter is completely combined. Fold in the flour-coated chocolate chips. Batter is thin and you may see some air bubbles on the surface—that’s normal. You should have about 6-6.5 cups of batter, or around 1400g.
- Divide batter evenly between 3 pans. Bake for approximately 24-26 minutes. Baking times vary, so keep an eye on yours. The cakes are done when a toothpick inserted in the center comes out clean.
- Remove the cakes from the oven and set on a wire rack. Allow to cool completely in the pan. The cakes may slightly sink in the middle as they cool—that’s expected.
- With a handheld or stand mixer fitted with a paddle or whisk attachment, beat the butter on medium speed until creamy, about 2 minutes. Add confectioners’ sugar, cocoa powder, heavy cream, salt, and vanilla extract. Beat on low speed for 30 seconds, then increase to high speed and beat for 1 full minute. Taste. Beat in another pinch of salt if desired. (Do you want your buttercream darker in color? I have a trick detailed on the full chocolate buttercream page.) You’re going to use this buttercream for a thin layer under the raspberry filling, a piped "dam" around 2 of the cake layers, and for the crumb coat. Makes about 2.5 cups total.
- Place 1 cooled cake layer on your cake stand or serving plate. Using a large icing spatula or small offset spatula, evenly cover the top with about 1/4 cup of chocolate buttercream frosting (a thin layer). Spoon about 1/2 cup of the chocolate buttercream into a piping bag fitted with a large round piping tip. I use Wilton 2A. (Or just use a disposable piping bag and cut about 3/4 inch off the tip and use that without a piping tip.) Pipe a thick border of buttercream around the edge of the frosted cake layer, using about half of the buttercream in the piping bag. Then, using a small offset spatula, spread half of the thickened and chilled raspberry filling (about 1/2 cup) inside the buttercream border. Place second cake layer on top and then repeat the filling process: spread frosting, pipe border with remaining frosting in piping bag (if you ran out, just use more from the big bowl of buttercream), then spread on remaining raspberry filling. Top with third cake layer.
- Using the remaining chocolate buttercream, spread a thin layer of buttercream on the top and around the sides as a crumb coat. Run a bench scraper around the cake to smooth out crumb coat. Chill uncovered in the refrigerator for at least 30 minutes and up to 3 hours to set the crumb coat.
- Place finely chopped chocolate in a medium heat-proof bowl. Heat the cream and raspberry liqueur, if using, in a small saucepan over medium heat until it begins to gently simmer. (Do not let it come to a rapid boil—that’s too hot!) Pour over chocolate, then let it sit for 2-3 minutes to gently soften the chocolate. With a metal spoon or small rubber spatula, very slowly stir until chocolate has melted and mixture is smooth. Ganache is thin. The finer you chopped the chocolate, the quicker it will melt with the cream. If it’s not melting, do not microwave it. If needed, see Troubleshooting Chocolate Ganache. Once ganache mixture is smooth, let it chill for 30 minutes in the refrigerator to thicken before spreading on chilled crumb-coated cake.
- Pour/spoon thickened ganache on chilled cake, and spread all over cake with an icing spatula. Garnish with fresh raspberries, if desired. Serve cake immediately or chill, uncovered, for up to 4-6 hours before serving. Cake can be served at room temperature or chilled.
- Cover leftover cake tightly and store in the refrigerator for 5 days. I like using a cake carrier for storing and transporting.

Note
My main note. I measure carefully and use texture cues before changing timing.
Cooling matters. I do not cut, dip, stack, or cover until the recipe has had time to set.
Chocolate quality shows. I use chocolate and cocoa I already like because there are not many places for dull flavor to hide.
Storage is part of the recipe. I cover tightly and separate layers with parchment when pieces might stick.
Frequently Asked Questions
Yes. I follow the chilling or cooling directions, then cover tightly until serving.
Usually, as long as the amount stays the same and the chocolate melts well.
Texture. I look for set edges, glossy melted chocolate, a thick filling, or a clean skewer depending on the recipe.
I cool completely, cover tightly, and refrigerate when the recipe includes cream, filling, or soft frosting.
Most sturdy cakes, bars, cookies, and candies freeze well; mousse and fresh garnishes are better refrigerated.
