Pre-heat your oven to gas mark 5 or 170C
Cream together the butter and the sugar for the cupcakes in a large bowl.
When the mix is soft and creamy, slowly add the 2 eggs, beating with an electric whisk until fully combined.
Next fold in the flour and salt creating a light, airy mixture.
Place the mix into cupcake cakes no more than 2/3 full.
Bake in the centre of the oven for 15 minutes or until golden brown and springy to the touch.
Once baked, leave the cupcakes to cool on a wire rack before icing.
For the icing, melt the sugar and butter in a pan.
Add the evaporate milk and heat for at least half an hour or until the mix reaches softball stage on a sugar thermometer (don’t worry it’s worth it in the end).
Gently pour the icing over the cupcakes and finish with an extra sprinkling of brown sugar before serving.
