The Ultimate Chocolate Raspberry Fudge Cake

Published: Oct 8, 2023 by Zoha · This post may contain affiliate links · 29 Comments

↓ Jump to Recipe

This is it: this is the ULTIMATE Chocolate Raspberry Fudge Cake. Inspired by the famous chocolate cake from the opening credits of The Great British Bake Off, this cake is made with layers of moist, rich and decadent chocolate sponge sandwiched with a silky ganache and topped off with fresh raspberries which beautifully balance out the flavor and texture.

And, as a chocolate cake fanatic, I have to say this is the best chocolate cake I've ever made or eaten, which is saying a lot as I've made some incredible chocolate cakes before (such as my famous Chocolate Malt Cake and Easy Chocolate Cake From Scratch loved by many). This cake is far simpler to make and hits all the right spot, so I cannot recommend trying it enough!

WHAT MAKES THIS THE ULTIMATE CHOCOLATE RASPBERRY FUDGE CAKE?

I call this my "ultimate" chocolate raspberry fudge cake because it meets all the criteria an incredible chocolate cake should meet:

  • The most divine texture. The cake is moist and velvety, achieved by the addition of brown sugar and sour cream. The ganache is silky and rich. The raspberries are light and fresh. Together, every bite is perfectly balanced in texture
  • The perfect chocolate flavor. This cake tastes like chocolate, not sugar like many cakes tend to! And the addition of coffee and blooming the cocoa powder further enhance the chocolate flavor
  • A simple, no fuss recipe. This recipe takes only about 30 minutes of active work. The cake comes together in 2 bowls and a whisk (no mixer needed), the ganache is equally simple, the assembly is easy, and there are no fancy ingredients. In short, it is the perfect balance of low effort, high impact!

You will find many recipes for chocolate fudge cakes, including Paul Hollywood's own take. But I like this recipe the most because it is incredibly simple and tastes amazing. There are no complicated steps, the cake is made with cocoa only (no melted chocolate needed), and the result is sublime.

INGREDIENTS NEEDED

Here are the ingredients you will need to make this Chocolate Raspberry Fudge Cake (see the recipe card at the end of this post for the exact quantities):

Chocolate cake:

  • All purpose flour
  • Granulated sugar
  • Light brown sugar
  • Baking powder
  • Baking soda
  • Salt
  • Eggs
  • Vegetable oil
  • Sour cream
  • Instant coffee
  • Boiling water
  • Cocoa powder - I strongly recommend Dutch processed!

Ganache:

  • Heavy cream
  • Dark or semi sweet chocolate
  • Unsalted butter

Assembly:

  • Fresh raspberries - you may skip them if you don't like them, but I personally think they are needed to round out the flavor and texture of this cake

HOW TO MAKE THIS CHOCOLATE RASPBERRY FUDGE CAKE

First, check out this short video in which I demonstrate how to make this cake:

[adthrive-in-post-video-player video-id="b3xp4Ktx" upload-date="2023-10-09T04:07:16.000Z" name="The Ultimate Chocolate Raspberry Fudge Cake" description="How to make the most incredible chocolate raspberry fudge cake inspired by The Great British Bake Off" player-type="default" override-embed="default"]

Now, let's go through the steps one by one:

1. Bake the chocolate cakes

Preheat your oven to 350F and line 2 8" pans with parchment paper.

Whisk together all the dry ingredients except the coffee and cocoa powder. I strongly recommend sifting the flour to ensure it has no lumps in it. Add in the eggs, oil and sour cream, and whisk until combined and no lumps remain.

In a separate bowl, pour the boiling water over the cocoa powder and coffee, and whisk until a shiny mixture forms. This step blooms the cocoa powder, bringing out the lovely chocolatey flavor and aroma.

Fold the bloomed cocoa mixture into the remaining batter, using gentle motions and taking care not to over mix.

Divide the batter between the 2 pans and bake for ~30 minutes or until a toothpick inserted in the center comes out with moist crumbs attached.

Let the cakes cool inside the pans for 15-20 minutes, then turn them out and let them cool down fully.

Tip: I recommend cooling your cakes in the freezer for 1-2 hours. This makes it much easier to cut and frost them!

2. Make the chocolate ganache

While the cakes bake, get working on the chocolate ganache! Add the cream and butter to a saucepan and heat it until the mixture just starts to boil. Pour it over the chocolate in a heatproof bowl. Cover for 5 minutes, then whisk until a smooth, silky ganache forms.

Tip: While whisking ganache, try to use a gentle stirring motion to minimize the amount of air bubbles created. This will help achieve a silky ganache.

Cover the ganache with cling wrap and let it chill thoroughly until it reaches a thick, spreadable consistency. This can take a few hours, and I strongly recommend being patient!

Tip: If you're in a rush, you can pour the ganache into a large tray and then cover and chill so the surface area allows it to cool quicker.

3. Assemble the cake

Once the cakes and ganache are both chilled, you can start with the assembly. First, trim off the domes of the cakes using a large serrated knife; this will help make a level cake with even layers.

Place one cake on a turntable, and add a thick layer of ganache on top, using an offset spatula to spread it out evenly. Cover with the second cake placed upside down. Apply a thin layer of ganache to the top and sides of the cake to lock in the crumbs (this is called the crumb coat). Put the cake back in the fridge or freezer until the crumb coat sets. Then frost it all over with the remaining ganache!

4. Decorate and serve!

I recommend saving the raspberries until you are ready to serve. Once you are, cover the top of the cake with fresh, washed and dried raspberries. Serve and enjoy!

FREQUENTLY ASKED QUESTIONS

How to store chocolate fudge cake?

This cake should be stored in an airtight container in the fridge, or even kept in the freezer. Once the raspberries are added, the cake can be kept for 1-2 days as the raspberries start to go bad from the moisture. Without raspberries, it will keep in the fridge for up to 7 days or in the freezer for up to 3 months.

Can this chocolate raspberry fudge cake be made in advance?

Yes, you can make the cake in advance. I recommend frosting the cake with ganache and then storing it in the fridge. Don't add the raspberries until you are ready to serve as they can go bad quickly.

What is a substitute for egg in this cake?

You can substitute the eggs with flax seed eggs in this cake. For every egg, make a mixture of 1 tablespoon ground flax seeds + 3 tablespoon water. Mix and refrigerate until the mixture becomes gloopy, then add to the cake at the same step as the eggs.

What is a substitute for sour cream in this cake?

I strongly recommend sour cream for this cake as it enhances the texture and adds richness and moisture. However, if you don't have easy access to sour cream, you can replace it with the same quantity of buttermilk. To make buttermilk at home, add 2 tablespoon vinegar or lemon juice to every 1 cup of milk and stir.

Does the cake taste like coffee? Can the coffee be omitted?

No, this cake does not taste like coffee. The coffee simply enhances the chocolate flavor and I do recommend adding it. However, it is not mandatory and can be omitted.

Why is my cake crumbly or breaking?

This cake is delicate and needs to be handled with care. Make sure you let the cake cool down before taking it out of the pan, and then chill it thoroughly before assembling. Otherwise it can break. If your cake feels dry or crumbly even after chilling, it is possibly overbaked or you added too much flour.

Why is my ganache grainy / split?

Ganache can split and become grainy due to 2 common reasons: 1) overheating, and 2) overmixing.
Make sure to remove the cream and butter mixture from heat as soon as it starts to boil and pour over the chocolate; this will ensure the chocolate does not overheat and seize up.
When stirring the ganache, do it gently without adding too many air bubbles into the mixture. While refrigerating, avoid mixing the ganache too much as that will cause the cream in it to overwhip and become grainy.

Can I add raspberries to the middle of the cake as well?

Yes! You can add chopped raspberries or raspberry jam to the middle layer of the cake as well. Just keep in mind fresh raspberries will reduce the shelf life of the cake.

Can I skip the raspberries?

Yes, you can skip the raspberries. However, note that raspberries add freshness to the cake, and otherwise it may be a bit too heavy.

Can I use milk chocolate for the ganache instead of dark chocolate?

Yes, you can use milk chocolate for the ganache. However, I don't recommend it as it will make the cake a bit too sweet.

Can I make just half of this recipe?

Yes. You can make half the recipe and make 1 8" cake. Alternatively, you can make 2 6" cakes with half the recipe.

Can I eat this cake warm?

Yes! Without raspberries, this cake can be warmed in the microwave for a few seconds to make it warm and gooey.

Description

Inspired by the The Great British Bake Off, this cake is made with layers of moist, rich and decadent chocolate sponge sandwiched with a silky ganache and topped off with fresh raspberries which beautifully balance out the flavor and texture.


Ingredients

Chocolate Cake:

  • 2 cups all purpose flour (260g)
  • 1 cup granulated sugar (220g)
  • ½ cup brown sugar (100g)
  • 2 tsp baking powder
  • 1 tsp baking soda
  • 1 tsp salt
  • 2 eggs
  • ⅔ cup vegetable oil (133g)
  • 1 cup sour cream (240g)
  • 2 tsp instant coffee
  • ½ cup boiling water (120g)
  • ½ cup cocoa powder, Dutch processed preferred (50g)

Chocolate Ganache:

  • 300g dark or semi sweet chocolate (chips or chopped)
  • ¼ cup unsalted butter, diced (56g)
  • 1 ¾ cup heavy cream (420g)

Assembly:

  • 1-2 packs of raspberries

Instructions

Chocolate cake:

  • Preheat oven to 350F and line 2 8" pans with parchment paper
  • In a large bowl, mix together the flour, granulated sugar, brown sugar, baking powder, baking soda and salt, ensuring there are no lumps
  • Add in the eggs, vegetable oil and sour cream, and whisk gently until the ingredients are combined and there are no lumps; take care not to over mix
  • In a separate bowl, mix the boiling water with coffee and cocoa powder
  • Add the cocoa powder mixture to the remaining batter and gently mix until combined and a smooth chocolate cake batter forms. Take care not to over mix
  • Divide the batter equally between the two lined pans and bake for ~30 min

Chocolate Ganache:

  • In the meanwhile, add the heavy cream and butter to a saucepan and bring to a boil. Pour over the chocolate, cover and wait 5 minutes. Then stir gently until a smooth shiny ganache forms. Cover and refrigerate until the ganache reaches a thick, spreadable consistency (this can take a few hours)
  • Once the cakes are baked, leave them to cool in the pans for 15 minutes, then turn them out and let them cool down all the way. I like to chill them in the freezer

Assembly:

  • When the cakes are chilled and the ganache is spreadable, it is time to assemble. Trim off the tops (domes) of the cakes, and layer them with a thick layer of ganache in between
  • Cover the cake with a thin layer of ganache to trap in the crumbs (known as the crumb coat). Refrigerate until the crumb coat is set
  • Frost the cake with the remaining ganache generously, making the edges as neat as possible
  • Cover the top with fresh raspberries
  • Serve and enjoy!

Notes

  • Make sure to measure ingredients accurately for the best results
  • Allow the cakes to cool down fully before handling / cutting / frosting them
  • Allow the ganache to cool down fully in the fridge so it is spreadable and pipeable like buttercream

    Amazing!! So simple but it does require patience in terms of freezing, cooling the icing and the crumb coat. However the effort pays off for the results in the end are incredible. I even managed to ice it decently! Thank you Zoha for the very clear instructions.

    I used butter in place of the vegetable oil and apparently that was not a good idea. I was very disappointed in the cake. The cake cooked very quickly and didn’t really have a great flavor. I only baked it for 20mins and it still seemed on the dry side. The ganache was delicious. Sadly I don’t think I will make this again.

    I’m a very amateur baker but this recipe was amazing! I whipped the ganache after it set up a bit because I prefer that texture and I had enough leftover that I turned it into iced cream! Mine definitely isn’t pretty in anyway but it still tasted amazing. Definitely recommending to my friends.

    Hi Zoha, I made the cake this weekend. It was delicious, but I think I could greatly improve the texture. Any tips on how to get the ganache silky smooth & shiny? Mine ended up being too firm and rough looking. I think I overcooked the sponges too - but that is an easier fix as I know oven times can vary. The raspberries are a must! Gina

      July 10, 2024 at 12:35 pm

      Hi Gina! Glad you liked the recipe. For the ganache - you need to ensure that the cream is just starting to boil when you pour it over the chocolate. Make sure the chocolate is cut into small chunks. Let sit, then whisk slowly and gently until the chocolate is fully melted in the cream. If you see some chunks of unmelted chocolate, microwave for 10 seconds to make it melt. Then cover with cling wrap to chill. And for the sponges, yes you can definitely improve that next time now that you know how long to bake them!

Could I make the cake ahead of time and freeze it . Then add the frosting after it’s defrosted on the day? Do you think it would be ok? Thanks

      Thanks so much, Deb! Yes, you can absolutely bake the cake layers, wrap them in cling wrap once they've cooled down, and keep them in the freezer. You can even frost them while they're still frozen, and then let them thaw out in the fridge / at room temp. Just don't freeze raspberries 🙂
