Sour-Cream Chocolate Cake

My son’s birthday is coming up and, within the space of a year, he has suddenly acquired the ability to compose his own birthday wish list, probably a necessary skill in the evolution of a toddler to prevent their well-meaning parents from buying the “wrong” gifts and thus forcing them to play with the more interesting packaging instead.

My son’s wish for his birthday this year is a homemade cake. I’m relieved that his expectations are quite low, but equally alarmed by this seemingly innocent request. I’m not sure where he may have picked up the phrase “homemade”, but it’s possible that he’s trying to tell me that it’s been a while since I’ve baked anything.

Once upon a time, our cake stand used to always boast a sweet treat, something to look forward to at afternoon tea or for dessert. Lately, in my frazzled post-partum state, it often sits bare or is, instead, garnished with seasonal fruit, neither of which are particularly appealing to my sweet-toothed toddler.

In the past few weeks, my son’s birthday request has evolved into a more complicated green dinosaur cake à la George from Peppa Pig (but still homemade). I’m hopeful that I can convince him that a brown dinosaur cake will be just as fun, and this is the recipe I intend to make.

This recipe for Sour-Cream Chocolate Cake comes from How to be a Domestic Goddess by Nigella Lawson. I’m quite sure that this recipe was the precursor to the Old-Fashioned Chocolate Cake in Nigella Lawson’s later book, Feast; both recipes are quite similar in terms of ingredients, although the latter boasts a speedier method using the food processor.

Chocolate Cake Recipe

I’m a big fan of the Old-Fashioned Chocolate Cake (which I made here for a birthday party for a friend’s daughter), but I make this Sour-Cream Chocolate Cake just as frequently and, for some inexplicable reason, I seem to prefer it.

Perhaps it comes down to the icing – the mix of milk and dark chocolate makes it sweeter and more comforting, and which makes it more appealing to childrens’ palates than if you were to use all dark chocolate.

And once you have tried a chocolate cake with sour cream, you will understand why it is the most delicious and moist chocolate cake you will ever taste. Sour cream not only adds a slight tang to the cake to cut through the sweetness of the chocolate, but it also keeps the cake moist, which is a bonus if you want to bake the cake in advance before a party.

How to Make Chocolate Cake

Making a chocolate cake from scratch is so easy once you understand the basics of making a cake.

Traditionally, the butter and sugar is first creamed together, before the dry ingredients are gently folded through. A good chocolate cake usually relies on the addition of real chocolate or good quality cocoa powder. Any extra ingredients, such as vanilla or sour cream, are added for additional flavour and moisture.

What I love about the chocolate cake recipe below is that everything is placed into the food processor, at the same time, and blitzed until you have a smooth batter. It is so easy!

I have since adapted this Sour-Cream Chocolate Cake to make it even easier, especially for childrens’ birthday parties. Please see my recipe for Easy Chocolate Cake.

For the chocolate cake

For the chocolate icing


For the chocolate cake

  1. Preheat the oven to 180°C (350°F) (without fan).
  2. Line and grease 2 x 20cm (8 inch) round cake tins.
  3. In a small bowl or jug, lightly whisk together the sour cream, eggs and vanilla extract.
  4. Place the flour, cocoa, sugar, baking powder, baking soda, salt and butter into the bowl of a stand mixer with the flat paddle attachment.
  5. Beat on low speed until the butter is incorporated into the dry ingredients.
  6. Slowly add the egg mixture and beat until the batter is thoroughly mixed.
  7. Pour the batter evenly into the prepared cake tins.
  8. Bake for about 25 to 30 minutes, or until a skewer inserted in the middle comes out clean.
  9. Place the cake tins on a wire rack and let the cakes cool in the tins for about 10 minutes, before turning them onto the wire rack to cool completely.
  10. I often make the cakes the night before serving and leave them to cool overnight.

For the chocolate icing

  1. To make the icing, melt the chocolate and butter in a bain-marie or a bowl over a pan of simmering water, taking care not to let the bowl come into contact with the water.
  2. Once the chocolate has melted, take the bowl off the heat.
  3. Stir in the sour cream, vanilla extract and golden syrup.
  4. Whisk the icing sugar into the chocolate mixture.
  5. Add some hot water (from the tap is fine), a few drops at a time, until you have the right consistency.
  6. The icing should be thick enough to cover the cake, but soft enough to spread easily.

To assemble the cake

  1. Cut four thick strips of baking paper and place them on a large plate or cake stand in the shape of a square. The baking paper is to help keep the serving plate clean while you are icing the cake.
  2. Place one cake on top of the baking paper.
  3. Spread about 1/3 of the icing over the cake in a thick layer.
  4. Place the second cake on top and spread another 1/3 of icing over the cake.
  5. Use the remaining icing to cover the sides of the cake.
  6. Once you have finished icing the cake, carefully remove the pieces of baking paper.
  7. Leave the cake to set for at least an hour before serving.
  8. The cake keeps well on a covered cake stand for a few days.

Kitchen Notes

As this is one of my go-to recipes for birthday cakes, I thought it would be helpful to also provide baking times when using different sized cake pans.

12 cm (5 inch) round cake pan
Fill the pan with batter to about 2 cm from the top. Bake for 20-25 minutes, or until a skewer inserted in the centre comes out clean.

16 cm (6 inch) round cake pan
Fill the pan with batter to about 2 cm from the top. Bake for 25-35 minutes, or until a skewer inserted in the centre comes out clean.

23 cm (9 inch) round cake pan
The above recipe can be used to fill one cake pan of this size. To make a double-layer cake, double the above recipe and use two pans of this size. Fill the pan with batter to about 2 cm from the top. Bake for 35-40 minutes, or until a skewer inserted in the centre comes out clean.

26 cm (10 inch) round cake pan
The above recipe can be used to fill one cake pan of this size. To make a double-layer cake, double the above recipe and use two pans of this size. Fill the pan with batter. Bake for 35-40 minutes, or until a skewer inserted in the centre comes out clean.

The nutritional information is higher than it should be because not all of the frosting is required to ice this cake.

All recipes on this website state temperatures for a regular oven (i.e. a conventional oven without fan). If you have a convection oven with a fan, please consult the manufacturer’s handbook on how to adjust the temperature and baking time accordingly.

  1. This cake looks just perfect! I want a thick slice with my 11.00am mug of coffee!

    Happy Birthday to your little man!

    • Eat, Little Bird 27 November 2015

      Thanks, Angela! I’m getting ready to make three birthday cakes this weekend … my little guy is pretty excited about the big day! 🙂

  2. Louise | Cygnet Kitchen 12 December 2015

    You had me at ‘chocolate’! I bet this cakes tastes as good as it looks. Happy Belated Birthday to your son, I hope he had a wonderful day! x

    • Eat, Little Bird 13 December 2015

      Oh thank you! My son is still celebrating 🙂 It’s so cute when he sings Happy Birthday to himself that I can’t quite tell him yet that he needs to wait another year 😉

  3. James 22 July 2016

    I couldn’t get this recipe to work, seems like too much dry ingredients compared to wet.

    • Eat, Little Bird 22 July 2016

      Hi James, sorry to hear that this recipe didn’t work for you. This recipe produces quite a thick batter, but it should still produce a nice, moist cake. Did you use an electric stand mixer or did you do everything by hand? If the latter, my guess is that it would be a bit difficult to mix the butter into the dry ingredients by hand, and maybe that’s why the cake didn’t work out?

      If making this cake by hand, I would start by creaming (with a bowl and wooden spoon) the butter and sugar together until it is light creamy, and then adding the rest of the dry ingredients, followed by the wet ingredients. I hope this helps.

  4. Alex 17 January 2017

    Ah, what a beauty! Put sour cream in or on anything and it is sure to be a hit 🙂

  5. Julie 19 February 2017

    Have made this before and perfect.
    This time however my chocolate topping was too runny.
    Can you help?

    • Eat, Little Bird 19 February 2017

      Hi Julie,
      If the icing is too runny, you can always try to “thicken” it with some more icing sugar. Just try adding a tablespoon at a time until you get the consistency you want. Sometimes, the type of icing sugar makes a difference, i.e. if the icing sugar is too fine, you generally need more icing sugar than normal. Hope this helps!

  7. Many manyyy Thanks!!! for offering this very simple and amazing recipe. It is too simple to understand by Everyone. Again Thankyou so much!!!!

  8. Jess 20 June 2017

    This is the best chocolate cake I’ve ever made. Thank you xx it was hard to share.
    mixture was a bit dry and hard to work so I added a dash of milk before spreading into the pans.

    • Eat, Little Bird 28 July 2017

      Hi Jess,
      Many thanks for your feedback! I’m glad you enjoyed this recipe, and I agree that it is “the best” chocolate cake 🙂 Sounds like you are an experienced baker, as a dash of milk would definitely make the batter easier to work with if it feels a bit too dry or thick. Ingredients work differently in different climates and in different kitchens, so thanks for sharing your tip!

  9. Alma Romero 15 August 2017

    Hi, the cake looks delicious, I have a question, for the buttercream can I substitute the chocolates for Nutella? Than you!

    • Eat, Little Bird 16 August 2017

      I’ve never tried to make the frosting with Nutella but you could certainly try and I think it would be pretty well 🙂 You may not need the same quantity of Nutella. Please let me know if you try it!

  10. Teri Sutton 24 August 2017

    Has anyone tried to freeze this recipe? I’ve made lots of times fresh but would like to be able to freeze it.

    • Eat, Little Bird 26 August 2017

      I’ve never tried freezing this recipe, sorry. Our freezer can barely fit a tub of ice-cream 😉 But from what I’ve read elsewhere, others have had much success in freezing the un-iced sponge cakes.

  11. Mamabakes 9 October 2017

    How about if i make it as a cupcake?what is the temperature and how many minutes?

    • Eat, Little Bird 9 October 2017

      I haven’t tried using this recipe for cupcakes yet, although the thought has crossed my mind several times. Hopefully someone else will be able to answer your questions.

    Hi, Made the cake today, I’ve got nice crumb, moist, the only thing is I don’t get the same color of cake as yours. Very light in chocolate. Overall it’s a nice cake! Thank you.

    • Eat, Little Bird 24 August 2018

      I’m glad that you enjoyed the cake! What type of chocolate did you use? I use chocolate with 70% cocoa content (Lindt brand usually), and I find that this and dark chocolate in general gives a nice, rich brown colour to cakes and chocolate frosting. If you used chocolate with less cocoa content, this might affect the colour of the cake. The type of cocoa powder you use can also make a difference. But what is most important is that the cake tastes good 🙂

  19. Stella 1 September 2018

    I followed the recipe but it turned out SUPER SUPER dry. What happened?

    • Eat, Little Bird 1 September 2018

      Hi Stella,
      Did you use the fan on your oven? My recipes are for oven temperatures without fan, so using a fan could make a difference. Also, all ovens are different so you might have to adjust for a few minutes either side of the recommended baking time. Sorry that the cakes turned out dry!

  20. Madeleine 14 October 2018

    I made this cake for my daughter’s birthday this weekend and it turned out absolutely perfect! The cake was nice and moist and everyone just loved it. I’ve never received so many requests for a recipe before! For the frosting, I used slightly more milk chocolate as we were mostly feeding kids. Next time, I will definitely make a larger size!

    • Eat, Little Bird 15 October 2018

      That’s wonderful to hear! So glad that everyone enjoyed this recipe. I always look forward to making this cake 🙂

  21. Meghan 16 October 2018

    Excellent recipe! Made this for my co-worker’s birthday at the office and everyone loved it. There was a bit of leftover frosting but it was so delicious.
