Put the egg whites into the bowl of a stand mixer with the whisk attached.
*= 15 drops of Foodie Flavours equates to about a 1/4 tsp worth of the flavouring. I suggest measuring this into a spoon as some bottles pour faster than others and they are very strong flavourings, you don't want to add too much.
These cupcakes are best kept in the fridge if not using straight away as the frosting is soft and will slump if left at room temperature on a warm day.

If you can't get the butterscotch morsels, chopped Caramac bars are a very decent alternative (plus a lot cheaper here in the UK!).
