Mary Berry Marble Cake Recipe

This soft, buttery Mary Berry Marble Cake is made with self-raising flour, eggs, and rich cocoa powder, ready in 1 hour and 15 minutes. The true magic happens when you slice through the tender crumb to reveal striking chocolate and vanilla swirls. I always keep a slice on the counter for my afternoon tea.

Why This Classic Works

I used to think making a marbled sponge required complicated layering techniques and careful folding. Mary Berry’s all-in-one method completely changed how I approach this bake. You just beat the base ingredients together, split the batter, and add cocoa to one half.

The real secret I discovered is using a skewer to create the swirls. Dragging it through the two batters creates distinct patterns without muddying the colours.

Mary Berry Marble Cake Ingredients

• 225g softened butter
• 225g caster sugar
• 225g self-raising flour
• 4 large eggs
• 2 tbsp milk
• 1 tsp vanilla extract
• 2 tbsp cocoa powder
• 1 tbsp warm water

How To Make Mary Berry Marble Cake

1. Prep the tin: Preheat your oven to 160C (140C fan) and line a 2lb loaf tin with baking parchment.
2. Mix the base batter: In a large bowl, beat the butter, sugar, flour, eggs, milk, and vanilla extract until smooth.
3. Divide and flavour: Spoon half the mixture into a separate bowl. Mix the cocoa powder and warm water into a paste, then fold it into one of the bowls.
4. Layer the batters: Drop alternating spoonfuls of the vanilla and chocolate batters into the prepared tin until all the mixture is used.
5. Swirl the cake: Take a skewer and drag it gently through the batter in a figure-of-eight motion to create the marble effect.
6. Bake and cool: Bake for 50-60 minutes until a skewer inserted comes out clean, then leave to cool in the tin.

Recipe Tips

• Use room temperature ingredients: Soft butter and room temperature eggs blend much easier and prevent the batter from curdling.
• Do not over-swirl: Swirling too much will blend the batters together and ruin the clear marble pattern.
• Check the bake early: Ovens vary significantly, so test the cake at 50 minutes with a skewer to avoid drying out the sponge.

What To Serve With Marble Cake

Serve this classic sponge with a hot cup of Earl Grey tea or strong black coffee. It also pairs wonderfully with a dollop of clotted cream or a simple dusting of icing sugar.

How To Store

Store the cooled cake in an airtight container at room temperature for up to 4 days. You can also wrap the whole cake tightly in cling film and freeze it for up to 3 months. Thaw overnight at room temperature before slicing.

FAQs

Can I use plain flour?

Yes, but you will need to add 2 teaspoons of baking powder to ensure the sponge rises properly.

Why did my cake sink in the middle?

Opening the oven door too early or underbaking the sponge can cause the middle to collapse.

Can I bake this in a round tin?

Absolutely, you can use a 20cm round cake tin. You will need to reduce the baking time to 40-45 minutes.

How do I stop the top from burning?

If the cake is browning too quickly, cover it loosely with foil for the last 15 minutes of baking.
