Ultimate Marble Cake

I’ve been planning this Ultimate Marble Cake for a while and I’m so thrilled with how it has turned out. Marble cake is usually a fairly simple loaf cake made with chocolate and vanilla sponge that has been swirled together. I wanted to elevate the cake and make it look super classy and elegant. This could easily be a birthday or celebration cake as it’s such a showstopper! My Ultimate Marble Cake is made up of three sponge layers, all of which are a combination of chocolate and vanilla sponges. The striped buttercream is a new technique to me and this was my first time trying it. It’s actually simpler than you might think to do, providing you have the right tools, and I think the effect is so striking!

Jump straight to the recipe!

  

I made a vanilla sponge and a chocolate sponge in separate bowls.

  

Then I added the sponges in alternate blobs to three greased and lined cake tins. I continued until all of the batter was used up. The batter will spread out and fill the tin as you add it.

I baked them for 30 minutes until a skewer inserted came out clean.

  

I made a chocolate buttercream and a vanilla buttercream in separate bowls.

  

After levelling off the cakes, I started to stack them. I put chocolate buttercream on the first sponge and vanilla buttercream on the second sponge.

  

I covered the whole cake in a thin layer of vanilla buttercream as the crumb coat, and put it in the fridge for 30 minutes. To create the striped effect I piped lines of alternating chocolate and vanilla buttercream all around the cake. I used my scraper to smooth the sides, making sure to wipe of excess buttercream from the scraper as I went.

Once I’d smoothed out the sides and I was happy with it, I added buttercream to the top and smoothed it out. Then I piped alternating rosettes of chocolate and vanilla buttercream and filled the centre with triple chocolate curl sprinkles.

I think this is the cake I am most proud of so far! I literally jumped for joy when it was finished as it looks so striking and pretty. This would be an amazing showstopper cake for a celebration or a birthday, and you could adapt the Ultimate Marble Cake to have a different flavour sponge or different coloured buttercream stripes.

To top it all off, the Ultimate Marble Cake was so yummy! Chocolate and vanilla are such classic flavours you really can’t go wrong with them!

  • 2 tsp Vanilla extract

For the chocolate sponge

  • 290 g Caster sugar
  • 5 Eggs
  • 250 g Self raising flour
  • 40 g Cocoa powder
  • 1 tbsp Milk

For the chocolate buttecream

  • 250 g Butter or baking spread
  • 440 g Icing sugar
  • 60 g Cocoa powder
  • 1 tbsp Milk

For the vanilla buttercream

  • 250 g Butter or baking spread
  • 500 g Icing sugar
  • 2 tsp Vanilla extract

For decoration

  • Triple chocolate curls

Instructions

  1. Pre-heat your oven to 160C Fan/180C/350F/Gas Mark 4, and grease and line three 8" cake tins

  2. Make the vanilla sponge by mixing the butter and caster sugar in a large bowl with a spoon until fluffy, or mix using an electric mixer

  3. Add the eggs and vanilla extract, and whisk until fully incorporated

  4. Add the self raising flour and whisk in until you can't see any flour anymore

  5. Make the chocolate sponge by mixing the butter and caster sugar in a large bowl with a spoon until fluffy, or mix using an electric mixer

  6. Add the eggs and milk, and whisk until fully incorporated

  7. Add the self raising flour, cocoa powder and whisk in until you can't see any flour anymore

  8. Add the batter to the cake tins in alternate spoonfuls, place each spoonful on top of the previous one. Continue until all of the batter is used up. The batter will spread out and fill the tin as you add it, but you can give them a little shake if needed to encourage it

  9. Bake them for 30 minutes or until a skewer inserted in the middle comes out clean. Leave them to fully cool either in the tins or on cooling racks

  10. To make the chocolate buttercream mix the butter, cocoa powder and icing sugar together. Once it starts to come together add the milk and mix until smooth. I use my electric hand whisk to do this but you can also do it by hand with a spoon

  11. To make the vanilla buttercream mix the butter and icing sugar together. Once it starts to come together add the vanilla extract and mix until smooth. I use my electric hand whisk to do this but you can also do it by hand with a spoon

  12. If the cakes have domed on top, level them off with a cake leveller

  13. Put one of the sponges on a decorating turntable and spread a layer of chocolate buttercream over it

  14. Add the second sponge on top and spread a layer of vanilla buttercream over it

  15. Add the third sponge and then cover the whole cake in a thin layer of vanilla buttercream as the crumb coat, then put it in the fridge for 30 minutes

  16. To create the striped effect, pipe lines of alternating chocolate and vanilla buttercream all around the sides of the cake. Use a cake scraper to smooth the sides and create the stripey effect, making sure to wipe off excess buttercream from the scraper as you go

  17. Once the sides are smoothed to your liking, add more buttercream to the top of the cake and smooth it out using a palette knife

  18. Then pipe alternating rosettes of chocolate and vanilla buttercream on top of the cake round the edge, and fill the centre with triple chocolate curl sprinkles - or any sprinkles of your choice

  19. Move the cake onto a serving plate or cake stand and dig in! Leftovers will keep in an airtight container for 2-3 days

  1. You definitely know how to get everybody’s attention, Kat! 😀 This cake looks absolutely fantastic and I don’t have to choose between chocolate and vanilla coz with your cake, I could have them both. 😀 Thanks for sharing at Fiesta Friday party, Kat! x

  2. Wow Kat, you’ve certainly achieved the classy and elegant feel that you were aiming for – it’s a stunner! It reminds me a little bit of a zebra cake (I think that’s what they call them – never tried it) to get those gorgeous vertical layers in the sponge 🙂

    1. Thank you! Yes I was in two minds about whether to call it a marble or zebra cake as they are both very similar!

  3. Wow, this is amazing Kat. You’ve done those stripes so cleverly. Definitely the ultimate marble cake. Thanks for sharing with #WeShouldCocoa.
