Buttercream filler recipe

1/2 cup milk
1/8 to 1/4 teaspoon salt
1/2 teaspoon Vanilla
2 sticks butter, cut into ½ inch slices

Do you think they will be okayin the fridge for a week and a bit?
Thanks

1 week is how long it will last in the fridge. I like to do 5-6 days tops. You can freze it, but 1 week is what I have read is the longest in the fridge. Hope this helps.

Thank-you...I have read I week as well but you can't always trust everything you read.

How is icing once you freeze it?? Is it runny at all?Does it depend on the icing?

Thanks
