Once it’s ready it’ll be a thin syrup consistency and a deep orange colour. Remember it will be very hot and as such will be a bit thicker once it cools down.

For the Cupcakes:

Sift the flour, sugar & baking powder into a large bowl.

Add the butter and mix on a medium speed until the mixture resembles a sandy consistency.

Gradually add half the milk to the mixture. Whisk the egg & 4 tbsp syrup into the remaining milk and again gradually add to the other ingredients. Mix until only combined – do not over mix!

Using an ice cream scoop, fill your cupcake cases 2/3 full and bake for around 20 minutes until a skewer comes out of the cupcakes clean.

When cool enough to touch, transfer to a wire rack to cool completely.

For the icing:

Sift the icing sugar into a large bowl, add the butter and mix on a slow-medium speed with a clean tea towel over your mixer to prevent your kitchen filling with icing sugar!

When the butter & sugar start to come together, gradually add 4-5 tbsp of Irn Bru syrup a spoonful at a time.

Continue to mix until completely combined and of a light & fluffy consistency.

If you want a deeper orange colour, add some orange food colouring. Just don't use too much as it can go extremely orange if so.

Ice the cupcakes and leave to set before enjoy!
