Mary Berry Marble Cake Recipe

Marble Cake Ingredients

For the Cake

  • 225g unsalted butter, softened, plus extra for greasing
  • 225g caster sugar
  • 4 large eggs, at room temperature
  • 225g self-raising flour
  • 1 teaspoon baking powder
  • 1 teaspoon vanilla extract
  • 2 tablespoons milk
  • 2 tablespoons unsweetened cocoa powder
  • 2 tablespoons hot water

Kitchen Equipment

  • 20cm round, deep cake tin
  • Baking parchment
  • Large mixing bowl and small bowl
  • Electric hand mixer or wooden spoon
  • Spatula, spoon, and skewer
  • Wire cooling rack

How to Make Mary Berry Marble Cake

  • Prepare the oven: Preheat the oven to 180°C or 160°C fan. Grease a deep 20cm round cake tin and line the base with baking parchment.
  • Make the vanilla batter: Put the softened butter, caster sugar, eggs, self-raising flour, baking powder, vanilla extract, and milk in a large bowl. Beat with an electric mixer for 1 to 2 minutes, just until smooth and combined. Scrape down the sides of the bowl as needed.
  • Mix the cocoa: In a small bowl, stir the cocoa powder and hot water together until you have a smooth paste. Let it cool briefly.
  • Make the chocolate batter: Transfer roughly half the cake batter to a second bowl. Fold the cocoa paste into this portion until evenly mixed.
  • Fill and swirl: Spoon alternating dollops of vanilla and chocolate batter into the prepared tin. Run a skewer or the handle of a spoon through the mixture in a few broad figure-eight movements. Gently level the top without mixing the colors together completely.
  • Bake the cake: Bake on the middle shelf for 45 to 50 minutes, until the top is springy and a skewer inserted into the center comes out clean. If the cake is browning too quickly, loosely cover it with foil for the final part of baking.
  • Cool and serve: Leave the cake in the tin for 10 minutes, then turn it out onto a wire rack and remove the parchment. Let it cool completely before slicing. No filling or assembly is needed.
How to Make Mary Berry Marble Cake

Tips for the Best Marble Cake

How soft should the butter be?

The butter should be soft enough to leave an indentation when pressed, but not melted or greasy. Properly softened butter blends easily with the other ingredients and helps produce an even sponge.

How do I get a clear marble pattern?

Alternate spoonfuls of the two batters, then swirl only a few times. Too much mixing will blend the colors and give you a light chocolate cake rather than distinct ribbons.

Why is my marble cake dry?

Overbaking is a common cause. Start checking the cake at 45 minutes and remove it when a skewer comes out clean. Measuring the flour accurately and mixing only until combined also help keep the crumb tender.

How can I tell when the cake is baked?

The top should spring back lightly when pressed, and a skewer inserted into the center should come out without wet batter. If it needs longer, return it to the oven and check again after a few minutes.

Serving Suggestions

  • Serve a slice with a cup of tea or coffee.
  • Add fresh raspberries or strawberries for a fruity contrast.
  • Serve with a spoonful of lightly whipped cream.
  • Dust the cooled cake with a little icing sugar for a simple finish.

Storage Instructions

Room Temperature

Once completely cool, keep the cake in an airtight container at room temperature for up to 3 days. Store it in a cool place away from direct sunlight.

Refrigerator

Store the plain cake in an airtight container in the refrigerator for up to 5 days. Bring slices to room temperature before serving for the best texture. If serving with cream, refrigerate it separately and follow its use-by date.

Freezing

Wrap the completely cooled cake or individual slices tightly, then place in a freezer-safe container or bag. Freeze for up to 3 months. Thaw, still wrapped, at room temperature before serving.

Frequently Asked Questions

Can I make this marble cake in a loaf tin?

Yes. Use a lined 2lb loaf tin with a capacity of about 1.4 litres, and do not fill it more than two-thirds full. Baking time may be longer, so check the center with a skewer and cover the top loosely with foil if needed.

Can I use plain flour instead of self-raising flour?

Yes. Use 225g plain flour and add 3 teaspoons baking powder in total, including the teaspoon listed in the recipe. Whisk them together before adding to the batter.

Why did my marble cake sink in the middle?

The cake may have been underbaked, or the oven door may have been opened too early. Check that the oven is fully preheated and wait until near the end of baking before testing the center.

Can I add chocolate chips to marble cake?

Yes. Fold up to 75g chocolate chips into the batter before spooning it into the tin. Small chips distribute more evenly through the sponge.

Can I make marble cake ahead of time?

Yes. Bake it a day ahead, let it cool completely, and store it in an airtight container at room temperature. Slice shortly before serving to help keep it fresh.
