What You Need

Whip up this beautiful marble cake using ingredients you probably already have in your pantry and fridge!

Note: Scroll to the recipe card at the bottom for the ingredients quantities and full detailed method.

• Unsalted butter – it’s best to use unsalted butter as you can then control the amount of salt you add to the cake. However, you can use salted butter if you prefer (just omit the extra salt).
• Caster sugar – otherwise known as superfine or ultra-fine sugar. This is a very fine sugar (much finer than granulated sugar) that dissolves easily when creamed together with the butter. 
• Salt – a small pinch of salt brings out the flavour in baking recipes. However if you use salted butter, leave out the salt.
• Vanilla extract – or you can use vanilla essence or vanilla paste if you prefer.
• Eggs – use large eggs (approx 60 grams each), at room temperature.
• Self raising flour – also known as self-rising flour. If you don’t have self-raising flour, you can make your own homemade self-raising flour by adding 2 teaspoons of baking powder to every 1 cup of plain flour and sifting together. 
• Pink food colouring – you only need a small drop of food colouring to make a pretty pink cake batter and buttercream frosting!
• Cocoa powder – use regular, unsweetened cocoa powder.
• Milk – I prefer to use full-fat or full-cream milk in my baking.
• Icing sugar mixture – this has a little cornflour added to it to stop it from forming lumps. Icing sugar mixture sets softer than pure icing sugar (which sets hard!) I recommend using icing sugar mixture when making buttercream as it results in a smooth, soft, creamy and spreadable frosting. 

Equipment Required

Simple baking equipment required to make this easy marble butter cake.

• Thermomix, stand mixer or hand-held beaters.
• Round 20cm cake tin – greased and lined.
• Oven – I use a fan-forced oven. If you have a conventional oven, simply increase the temperature by 10-20 degrees celsius.

Step By Step Instructions

It takes just 15 minutes to prepare this pretty cake!

Note: Scroll to the recipe card at the bottom for the ingredients quantities and full detailed method.

Step 1 – Mix The Wet Ingredients

Preheat oven to 175 degrees celsius (fan-forced). Grease and line a round 20cm cake tin with baking paper. 

Place the butter, caster sugar, salt and vanilla extract into a bowl. Beat together with a stand-mixer or hand-held beaters until pale and fluffy (approximately 5 minutes). This allows air to enter the ingredients to create a cake with a light texture.

Slowly add the eggs one at a time while continuing to beat through, until completely combined. 

Step 2 – Add The Dry Ingredients

Sift in the self raising flour and gently fold through with a spoon until just combined. Don’t over-mix otherwise your cake can turn out heavy.

Step 3 – Colour The Cake Batter

Divide the mixture equally between three bowls.

In the first bowl, add one drop of pink food colouring and mix to combine. You only need a small drop of food colouring!

In the second bowl, add the cocoa powder and milk and mix to combine. 

Leave the remaining mixture plain. 

Step 4 – Create The Marble Effect

Place spoonfuls of the mixture into the prepared baking tin.

Use a knife to gently swirl the three colours to create a pattern. 

Place in the preheated oven and bake for 25-30 minutes or until tested with a skewer.

Step 5 – Make The Buttercream Frosting

Beat the butter in a bowl until pale and fluffy (this will take approximately 5 minutes). Scrape down the sides of the bowl every so often to ensure all the butter is beaten.

Slowly add the icing sugar mixture, milk, vanilla extract and 1 drop of pink food colouring and continue to beat until smooth and creamy.

Spread the buttercream frosting over the cooled marble cake.

Expert Tips

• Tips for making a light and moist marble cake – use butter (not margarine) as butter contains more fat which keeps cakes moist when baked. Beat the butter and sugar together thoroughly as this allows air to enter the ingredients. You will need to beat them for approximately 5 minutes. Beat between each addition of the eggs. Don’t beat the mixture once you’ve added the flour – just gently fold it through with a spoon.
• How to check if the cake is cooked – start checking if it’s ready approximately 10 minutes before the recipe states. The cake is ready when a skewer inserted into the middle comes out clean.
• If you find that your marble cake is browning too much in the oven – simply place a sheet of foil loosely over the top and continue cooking. 
• Tips for making buttercream – beat the butter until it’s completely pale, soft and creamy – this will take approximately 5 minutes. Stop every minute or so to scrape down the sides of the bowl to make sure t are no lumps of unbeaten butter. Sift the icing sugar mixture to avoid any lumps. 
• Storing marble cake – a marble cake can be stored at room temperature for up to 3 days (it’s also fine to leave this cake frosted with buttercream at room temperature for 3 days).
• Freezing marble cake – you can freeze an un-iced butter cake for up to 2 months (wrap in plastic wrap and then cover in two layers of foil).

RECIPE NOTES & TIPS

Sift the icing sugar mixture to avoid any lumps. Add 1-2 drops of food colouring if you would like your buttercream to be coloured. 
• Storing butter cake – butter cake can be stored at room temperature for up to 3 days (it’s also fine to leave a butter cake frosted with buttercream at room temperature for 3 days). Do not store butter cake in the fridge as it will dry out.
