How do you put birthday cake with butter cream icing into party bag without it becoming a gooey mess ?

[wheelybug]

I should use harder icing shouldn't I ? Would rather do buttercream as am panicing about colouring the other ....

Any ideas oh wise ones ?

(WB - when you cream your butter, add the colouring then, when its a solid colour, then add your icing sugar)

ooh great thanks for tip !

Greaseproof paper-butter icing is far easier to lick off than kitchen roll or napkins!

Good plan wheelybug!

I was talking about the unmixed stuff - looks like icing sugar in a white and green box. It ends up more like slightly chewy royal icing. Not sticky when it's set.
