What You Need
Nothing fancy here, just a handful of simple baking ingredients (that you probably already have in your pantry) are all you need!
Note: Please scroll to the recipe card at the bottom for ingredient quantities and the full detailed method.
For The Cake
- Cocoa powder – use regular, unsweetened cocoa powder.
- Self-raising flour – forms the structure of the cake and also gives the cake its lift. Self raising flour is a blend of plain flour and a rising agent. If you don’t have any, you can make your own by adding 2 teaspoons of baking powder for every 1 cup of plain flour.
- Caster sugar - also known as superfine sugar.
- Milk – full fat, whole milk is recommended for the best flavour and texture.
- Eggs – use room temperature eggs for best results. If they are straight from the fridge, you can simply place them in a bowl of warm water for 5 minutes while you prepare the other ingredients.
- Vanilla extract
- Butter – for best results, I recommend using real butter, rather than margarine or butter substitutes.
For The Icing
- Icing sugar – icing sugar mixture or pure icing sugar can be used. Icing sugar mixture will make a softer icing, whereas pure icing sugar sets the icing hard. You can also adjust the quantities to make the icing thinner or thicker, if preferred.
- Cocoa powder
- Hot water
- Sprinkles - optional but highly recommmended!
Step By Step Instructions
I just LOVE how easy it is to make this super easy chocolate cake from scratch.
Just a few simple steps and one bowl is all you need!
Note: Please scroll to the recipe card at the bottom of the post for ingredient quantities and the full detailed method.
Step 1 - Mix The Cake Batter
Sift the self-raising flour and cocoa powder together in a bowl. Add the caster sugar, milk, eggs, vanilla extract and melted butter. Beat with an electric mixer for 2-3 minutes until fluffy.
Step 2 - Bake
Spread the mixture into a prepared sheet pan (square baking tin) and bake at 170 degrees celsius for 25-30 minutes.
The cake will be ready when a skewer inserted into the middle of the cake comes out clean, with a few crumbs.
Cool the cake in the tin before transferring to a wire rack.
Step 3 - Make The Chocolate Icing
Sift the icing sugar and cocoa powder together in a bowl.
Add the hot water and stir until smooth and combined.
**This icing is completely forgiving, so if it's too thin, simply add a little more icing sugar, if it's too thick, add a little more hot water until you have the desired consistency.
Spread the icing over the cooled cake and top with sprinkles. Slice, and serve!
Expert Tips & FAQs
Follow these helpful tips for the BEST chocolate cake EVER!
The cake will be ready when a skewer inserted into the middle comes out clean.
Allow the cake to cool completely before adding the icing. Otherwise, it will melt and slide off the cake.
I always recommend sifting icing sugar so that you don't get lumps through it.
You can use either a soft icing sugar mixture or a pure icing sugar. Using the soft icing mixture will make a softer icing, whereas pure icing sugar sets much harder (sometimes better in lunchboxes!)
If you add the hot water and the consistency is too thin, just add more sifted icing sugar, and if the consistency is too thin, add a little more hot water until you get the consistency that you want.
This cake is best eaten in the first day or two, but will keep in an airtight container at room temperature for 3-4 days.
Sure, the un-iced cake can be frozen (whole, or cut into pieces) for up to 3 months. Before freezing, allow the cake to cool completely. Then, wrap it well and place it into an airtight container in the freezer. To thaw, leave the cake in the fridge overnight, or at room temperature for around 2 hours before serving. You can freeze it once iced too, but it is so easy to make the icing that I recommend freshly icing and decorating the thawed cake when ready to serve.

- To prepare the icing, sift the icing sugar and cocoa powder into a bowl. Add the hot water and mix until smooth and slightly runny. If your icing is too thick, add a little more water.
- Working quickly, spread the icing over the cake (use a hot knife to help spread the icing).

Thermomix Method
- Grease and line a 20cm sheet pan and set aside. Preheat oven to 170 degrees celsius (fan-forced).
- Melt the butter for 2 minutes, Speed 1, 100 degrees.
- Add the cocoa powder, self-raising flour, caster sugar, milk, eggs and vanilla extract. Mix fo 10 seconds, Speed 4 (MC removed).
- Scrape down the sides of the bowl and mix for a further 20 seconds, Speed 4 (MC removed).

Notes
- Baking tips - the cake will be ready when a skewer inserted into the middle comes out clean. Allow the cake to cool completely before adding the icing, otherwise, it will melt and drip down the sides of the cake.
- Icing sugar - I recommend you sift the icing sugar to avoid lumps. You can use either soft icing sugar mixture or pure icing sugar, however 'soft icing mixture' will result in a softer icing, 'pure icing sugar' sets harder.
- Consistency of icing - you want the icing to be spreadable but not so thin that it runs off the cake. If the icing mixture is too thin, just add a little more sifted icing sugar. If too thick, carefully add a little more hot water.
- Storing - this cake is best eaten in the first day or two, but will keep in an airtight container at room temperature for 3-4 days.
- Freezing - the un-iced cake can be frozen (whole, or cut into pieces) for up to 3 months. Before freezing, allow it to cool completely. Then, wrap the cake well and place it into an airtight container in the freezer. To thaw, leave the cake in the fridge overnight, or at room temperature for around 2 hours before serving. The iced cake can be frozen too, but the icing is so easy to make that I recommend freshly icing and decorating the thawed cake when ready to serve.
Lucy Goddard
Hi there
Is it a cup or half a cup of the self raising flour? The measurements are a bit confusing there.
Thank you!
Lucy
Hi Lucy, it's one cup xx
Jen Heppell
Hi Lucy,
I've just made this and it was so tasty, thank you.
I have a cooking question - why do you have to "Set aside to cool before turning out onto a wire rack."? What happens when you don't do this? is it best to allow other cakes & muffins to cool in the tins/silicon moulds before turning onto a wire rake?
Lucy
Hi Jen, I'm so glad you enjoyed it! Allowing it to cool slightly (not completely) allows the cake to hold together when you turn it onto a cooling rack. If you try and remove a cake straight away from the oven to a cooling rack, it will crumble and break. xx
