Add all of the ingredients in to the bowl and whip on high for five minutes.
Add it to a piping bag and pipe it in to rounds on to baking paper. Refrigerate until set and keep for up to a week or so in a sealed container. You can also ditch the piping bag and just add the whipped butter in to a butter container and store it the same way on to the fridge. Add on to your hot baked goods and you and your manuhiri (guests) will be smiling from ear to ear.
