Can I use can't believe it's not butter to make frosting?

[Whenisitmysleepytime]

I've run out of butter and don't fancy the trek to the shops.

Can I use it to make chocolate frosting?

TIA :)

eeeeeew, DON'T!

You could use it of course, but it would be joyless.

If you like the taste of it spread thickly on toast, you'd probably like it as buttercream icing. I don't see why you wouldn't.

I would, and have. Unless you're serving it to cake connoisseurs no-one will guess.

Bugger! No icing sugar either.
Out ti the shops it is. MUST learn to check ingredients before I start!
