This Sour Cream Chocolate Cake is the only chocolate cake recipe you will ever need for birthdays and celebrations. Recipe includes instructions for using different sized cake pans.
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.

- Prep Time: 20 mins
- Cook Time: 30 mins
- Total Time: 50 minutes
- Yield: Serves 10-12
- Category: Cakes
- Cuisine: British
For the chocolate cake
- 2/3 cup (150ml) sour cream or crème frâiche
- 2 eggs
- 1 1/2 teaspoons vanilla extract or vanilla bean paste
- 1 1/3 cups (200g) plain flour
- 1/3 cup (40g) best quality cocoa
- 1 cup (200g) caster sugar (superfine sugar)
- 3/4 teaspoon baking powder
- 1/4 teaspoon baking soda
- 1/2 teaspoon salt
- 2 sticks (200g) unsalted butter, softened
For the chocolate icing
- 3 oz (80g) milk chocolate (e.g. 42% cocoa)
- 3 oz (80 g) dark chocolate (e.g. 70% cocoa)
- 3/4 stick (75g) unsalted butter
- 1/2 cup (125ml) sour cream or crème frâiche
- 1 teaspoon vanilla extract or vanilla bean paste
- 1 tablespoon golden syrup (or light corn syrup)
- 2 1/4 cups (300g) icing sugar (powdered sugar), sifted
For the chocolate cake
- Preheat the oven to 180°C (350°F) (without fan).
- Line and grease 2 x 20cm (8 inch) round cake tins.
- In a small bowl or jug, lightly whisk together the sour cream, eggs and vanilla extract.
- Place the flour, cocoa, sugar, baking powder, baking soda, salt and butter into the bowl of a stand mixer with the flat paddle attachment.
- Beat on low speed until the butter is incorporated into the dry ingredients.
- Slowly add the egg mixture and beat until the batter is thoroughly mixed.
- Pour the batter evenly into the prepared cake tins.
- Bake for about 25 to 30 minutes, or until a skewer inserted in the middle comes out clean.
- 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.
- I often make the cakes the night before serving and leave them to cool overnight.
For the chocolate icing
- 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.
- Once the chocolate has melted, take the bowl off the heat.
- Stir in the sour cream, vanilla extract and golden syrup.
- Whisk the icing sugar into the chocolate mixture.
- Add some hot water (from the tap is fine), a few drops at a time, until you have the right consistency.
- The icing should be thick enough to cover the cake, but soft enough to spread easily.
To assemble the cake
- 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.
- Place one cake on top of the baking paper.
- Spread about 1/3 of the icing over the cake in a thick layer.
- Place the second cake on top and spread another 1/3 of icing over the cake.
- Use the remaining icing to cover the sides of the cake.
- Once you have finished icing the cake, carefully remove the pieces of baking paper.
- Leave the cake to set for at least an hour before serving.
- The cake keeps well on a covered cake stand for a few days.
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.
