White butter icing

[WittgensteinsBunny]

I'm making a unicorn cake at the weekend. How do you make white, white icing? My mum's suggested buying white frosting from Lakeland. Is there a foolproof way of making white icing?

Just cream cheese and icing sugar?

Cream cheese and icing sugar is a good one like the pp said. Or if it's strictly butter icing you want then beat the crap out of the butter and it goes white..ish.
You can do a cream icing, I had it on a cake the other day and it was delicious and whiter than white. No idea how it was made though..

I've made one of these and I used Trex

I think the brand of butter seems to make the biggest difference. I made a cake for my mil to take to work and everyone was amazed that the butter icing was so white. It was just the cheaply Waitrose essentials unsalted butter I always use for icing, but now I'm aware of it, it does give a very white colour as opposed to yellow. No idea why

Use Lurpak. That goes really white when whipped with icing sugar.

Cream cheese and icing sugar on its own isn't firm enough in my experience.

Get the palest butter you can, then beat it for good 5 mins or more, it will go much paler.

Beat the hell out of it, you can also get whitening powder or add a touch(really tiny amount) of sugarflair violet grape colouring.

Really helpful. Thank you very much!
