I need your best, and fool proof, recipes for butter cream (or is it butter icing?) to decorate DS2's birthday cake, please.

[NotABanana]

I will be adding colouring to make it blue and it needs to be a large amount as the mixture needed is 3 times Mary Berry's victoria sponge. The 9 egg car cake!

TIA

Is it just icing suagr and butter? Off shopping and need to get anything I have missed. Thanks.

How do I make that?

yep, just cream the butter (beat till fluffy if you cane manage it, or use a mixer) and add loads of icing sugar.

I think you can buy colour paste from cake shops (never use it meself). Or cheat and byuy ready-made fondant icing

I am done with shopping for today and didn't want to use anything shop bought so I will give it a go.

My plain is to pipe the butter cream all over the cake or maybe just spread it if that is easier as I have bits to decorate it with.

spreading much easier

then pipe white details

Okay.

Cake in oven.

Everything crossed.

Cake cooked.

Now cooling.
