Pre-heat your oven to 140C Fan/325F/Gas Mark 3, and line a cupcake tin with cupcake cases
For the cupcake sponge, mix together the butter and light brown soft sugar, ideally using an electric mixer, for 5 minutes until smooth and fluffy
Add the eggs and milk and whisk them in well
Then gently whisk, or fold in, the self raising flour, cocoa powder and baking powder
Divide the mixture between the cupcake cases, and bake them for 25-30 minutes or until a thin skewer inserted in the centre of the cupcakes comes out clean. Put them on a rack to cool completely
For the buttercream, mix the softened butter on it's own for a few minutes. Then add the icing sugar, golden syrup, vanilla extract and milk, and mix until smooth. You can do this by hand, but an electric hand whisk or 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 chopped up Crunchie bars and crumbs
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.
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.
I used golden syrup for the buttercream, you could use honey instead if you prefer.

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.
