Russian Buttercream

[Pifful]

Just made a big chocolate cake filled and iced with Russian buttercream (from Nancy Birtwhistle's recipe).
Now I realise it needs to be kept in the fridge. Which is full.
I wonder whether garage or unheated conservatory will be cool enough?

Yes. Off to Google Russian buttercream now.

wasn't familiar with this type so googled, is it just condensed milk, butter, salt, sugar, and vanilla? If so I think it might be ok covered and kept in a cold space such as garage, although it's annoying mild for this. If it involved fresh cream I would be far more worried.

Is it not possible to move things like wine or bottles of coke... to the cold spaces to give room for the cake. The drinks might not be ideal serving temperature but you can add ice into them and better than the risk of a delicious pud no-one can eat?

I'd keep that in cold place no problem, the coldest spot you can find in the house, would definitely be fine in my conservatory at the moment, it's unheated out there!

Yes it's butter, chocolate, condensed milk. It's delicious 😋.
I think I will risk conservatory, it would normally be below 5C this time of year but is probably more atm. I think it will all get eaten on Sunday and if not I'll cut up and freeze as there will be plenty of other stuff on Christmas day.
