  • 350g Butter or baking spread
  • 350g Caster sugar
  • 6 Large eggs
  • 2 tsp Orange extract
  • 1 tbsp Milk
  • 300g Self-raising flour
  • 50g Cocoa powder
  • 1/2 tsp Baking powder


  • 250g Butter or baking spread
  • 450g Icing sugar
  • 50g Cocoa powder
  • 1 1/2 tbsp Milk
  • 2 tsp Orange extract


  • 1 Terry’s Chocolate Orange
  • Orange sprinkles (optional)

Preparing the Sponge

To begin this baking adventure, preheat your oven to 160°C Fan/180°C/350°F/Gas Mark 4. Grease and line two 8″ cake tins. Now, let’s create the scrumptious sponge:

  • In a large bowl, mix the butter and caster sugar until fluffy. An electric mixer or a spoon will do the job.
  • Add the eggs, orange extract, and milk. Whisk until fully incorporated.
  • Gradually add the self-raising flour, cocoa powder, and baking powder, whisking until no flour remains.
  • Divide the mixture evenly between the tins. For precision, you can use kitchen scales.
  • Bake for 30-35 minutes or until a skewer inserted in the middle comes out clean. Allow the cakes to cool either in the tins or on cooling racks if removed from the tins.

Crafting the Mocha Buttercream

Now, let’s create the rich and indulgent mocha buttercream:

  • Mix the butter, cocoa powder, and icing sugar until they start coming together.
  • Add the orange extract and milk and continue mixing until the mixture becomes smooth. You can use an electric hand whisk or do it by hand with a spoon.

Assembling Your Cake

  • If your cakes have domed on top, level them off using a cake leveler or a serrated knife.
  • Place one of the sponges on your serving plate or cake stand. Pipe or spread a generous layer of the mocha buttercream onto it.
  • Gently place the other sponge on top and cover it with the remaining mocha buttercream.

Decorating with a Sweet Twist

To give your cake a delightful and eye-catching finish:

  • Decorate it with pieces of Terry’s Chocolate Orange and sprinkle some orange sprinkles if desired.

Storing Your Creation

If you’re not indulging right away, store the leftover cake in an airtight container in a cool place. It will stay fresh and delightful for 2-3 days.
