I'm rubbish at cake decorating but last year's was almost good, I coloured some icing navy blue and covered the cake with it, I then used a snowflake cutter to make white snowflakes which I then covered with sparkling sugar. Arranged on the cake and stuck down with vodka ( mother in law's semi pro decorators tip).
I've tried royal icing but no-one liked it , too much like meringue for my 3
You can roll it out quite thinly I never buy as much as they tell you. You can make marzipan. You could marzipan whole cake then roll out fondant into a rectangle (measure cake sides with a bit of string to get it the right length) then royal ice the top. Otherwise go with Sandland suggestion only I would just do the top and leave cake showing either side of a wide red ribbon. goose MIL is right The snowflakes are stunning dusted with hologram dust and you might have enough to make some. If you make them either with petal paste/ Mexican paste or 60/40 with fondant 40 then they can be made to stand up like they have fallen on the cake. I once made someone a 3 tiered wedding cake like this. Even if I do say it myself it was stunning and it was snowing when they came out which is what I was hoping for.
I spent a lot of yday evening on Pinterest trying to find an easy design! There’s one by Frances Quinn (bake off winner) that looked easy and effective. She covered the cake in white fondant icing, then cut out star shapes from the top of the cake with a biscuit cutter, and filled the holes with edible silver / gold balls.
Thank you everyone esp honeydragon for detailed steps.
Sainsbury’s sells marzipan and tubs of royal icing. I’ll pick up a palette knife. I can do rough and ready for snow and it will hide the marzipan which I fear maynot be smooth. I’ll pick up some cheap and cheerful trees and penguins. I take it I can use normal ribbon or should I buy cake one? I’ll wash it first.
