Pre-heat your oven to 160C Fan/180C/350F/Gas Mark 4, and line a cupcake tin with cupcake cases
For the cupcake sponge, mix together the butter and caster sugar, ideally using an electric mixer, until smooth and fluffy
Add the eggs and orange extract and whisk them in well
Then gently whisk in the self raising flour, baking powder and cocoa powder
Divide the mixture between the cupcakes cases, and bake them for 20-25 minutes or until a skewer inserted in the centre of the cupcakes comes out clean. Put them on a rack to cool completely
Make the buttercream by mixing together the butter, cocoa powder and icing sugar, then add the orange extract and milk, and mix until smooth. You can do this by hand, but an electric whisk are stand mixer with paddle attachment will provide the best results. If the buttercream is too stiff, you can add a little more milk
Spread or pipe the buttercream on top of the cupcakes
Decorate with the Terry's chocolate orange segments and orange sprinkles
Store in an airtight container in a cool place and eat within 3 days

Notes
Make sure all your ingredients (particularly the butter and eggs) are at room temperature before you start baking.
For the best flavour, make sure to use a good quality orange extract and not an essence.
I used a baking spread for the cupcakes and unsalted butter for the buttercream.
You can use any cocoa powder for the cupcakes, of course the better quality it is, the better flavour it will have. Also do make sure you are using cocoa powder and not a hot chocolate powder.
Although I provide cup measurements, I highly recommend weighing your ingredients out using digital kitchen scales. It is the most accurate way to measure ingredients and will ensure the best results. Digital scales are very low cost and can be purchased for around £12 ($16.50) .
For teaspoon (tsp) and tablespoon (tbsp) measurements, please use measuring spoons and not the type of spoons you eat with. Again this will ensure accuracy and provide the best results.
