Instructions

Preheat Oven and Prepare Tins:

  • - Preheat your oven to 160°C Fan/180°C/350°F/Gas Mark 4.
  • - Grease and line two 8" cake tins.

Make the Sponge:

  • - In a large bowl, mix the butter and caster sugar with a spoon until fluffy, or use an electric mixer.
  • - Add the eggs, orange extract, and milk. Whisk until fully incorporated.
  • - Add the self-raising flour, cocoa powder, and baking powder. Whisk until the batter is smooth and you can't see any flour.
  • - Divide the mixture evenly between the prepared tins. Use scales for accuracy.
  • - Bake for 30-35 minutes or until a skewer inserted in the middle comes out clean.
  • - Leave the cakes to cool completely, either in the tins or on cooling racks after removing them from the tins.

Make the Buttercream:

  • - In a bowl, mix the butter, cocoa powder, and icing sugar. Once it starts to come together, add the orange extract and milk.
  • - Mix until smooth. An electric hand whisk is ideal, but you can also do this by hand with a spoon.

Assemble the Cake:

  • - If the cakes have domed on top, level them with a cake leveller or a serrated knife.
  • - Place one sponge on your plate or cake stand. Pipe or spread some of the buttercream on it.
  • - Place the second sponge on top and pipe or spread the remaining buttercream over the top.
  • - Decorate with pieces of Terry’s Chocolate Orange and orange sprinkles, if using.

Serve and Store:

  • - Leftovers will keep in an airtight container in a cool place for 2-3 days.
  • Enjoy your delicious One-Bowl Chocolate Cake with Mocha Buttercream!
