How much buttercream frosting do I need for 12 cupcakes?

[ChampagneAndStrawberries]

I am very bad with quantities and don't want to end up with a fridgeful of buttercream or a miserly scraping on top of each cake. And I haven't hitherto been a great cupcake baker so I can't remember from last time I made them...

But I know that MN knows everything...

I have no idea of quantities - about 4 oz of butter I reckon and then enough icing sugar till it's the consistency you like

I normally make twice the amount as each cake requires at least one spoon for dcs and me. Just to make sure the taste is right of course.

Marvellous, thanks. I'll go with that (I do remember that I normally end up with about equal quantities of sugar and butter)

3oz Butter
6oz Icing Sugar

Should be perfect, I made 12 butterfly cakes this week with this amount.
