Preheat the oven on 180 degrees and fill a cupcake tray with paper cases

Add the butter and caster sugar into a mixer and mix until incorporated. Add each egg one at a time until they are both incorporated

Add the flour and bicarbonate of soda and icing sugar into the wet ingredients then mix until incorporated. Then add a few drops of red colouring to get a deep red colour then mix until fully incorporated.

Using an ice cream scoop, scoop the mixture into each of the cases then bake in the oven for 20 minutes or until golden brown.

Mix the butter until it's light and fluffy then add both icing sugars a little at a time until it's all incorporated.

Then add to a piping bag with a star nozzle on and pipe the icing on top of the cupcakes. Once finished add the little candy cane sprinkles.
