How to Make Mary Berry Chocolate and Orange Marble Cake

Prepare the oven: Preheat the oven to 180°C or 160°C fan. Grease and line a 20cm round cake tin with baking parchment.
Mix the base batter: Place the butter, caster sugar, eggs, flour, baking powder, milk, and orange zest into a large bowl. Beat well until smooth, pale, and fully combined.
Create the chocolate mixture: In a small bowl, mix the cocoa powder with hot water to form a smooth paste. Take one third of the cake batter and stir it into the cocoa mixture.
Layer the batter: Spoon alternating dollops of plain orange batter and chocolate batter into the prepared tin.
Marble effect: Use a skewer or knife to gently swirl the mixtures together to create a marbled pattern. Do not overmix.
Bake the cake: Bake for 45 to 50 minutes until well risen and a skewer inserted into the centre comes out clean.
Cool the cake: Leave to cool in the tin for 10 minutes, then transfer to a wire rack to cool completely.
Finish and serve: Dust lightly with icing sugar before slicing and serving.

Tips

How do I get a clear marble pattern?

Use a light hand when swirling the batters. A few gentle strokes are enough to create a defined pattern without blending the colours too much.

Why is my cake dense?

This usually happens if the batter is overmixed or the butter was too cold. Always use softened butter and mix just until combined.

Can I make the flavour stronger?

Yes, you can add a few drops of orange extract or increase the zest slightly for a more pronounced citrus flavour.

How do I know when the cake is done?

The cake should be golden, springy to the touch, and a skewer inserted into the centre should come out clean.

FAQs

Can I use fresh orange juice instead of zest?

Zest gives a stronger flavour without adding extra liquid. You can add a little juice, but reduce the milk slightly to balance the consistency.

Can I bake this in a loaf tin?

Yes, use a standard loaf tin and increase the baking time to around 55 to 60 minutes. Check with a skewer for doneness.

Can I make this cake ahead of time?

Yes, it keeps well for several days and can also be frozen, making it perfect for preparing in advance.

What cocoa powder works best?

Use a good quality unsweetened cocoa powder for a rich chocolate flavour and deep colour.
