How long can you keep it? I made it 2 weeks ago tomorrow and put it in the fridge. Sadly, I had actually forgotten about it b/c it got pushed to the back of the fridge I was going to make more tonight, then found it when I was making dinner! Is it still ok?

If in the fridge, should be just fine. I have kept buttercream refrigerated for a month.

You can PM her and ask.

It's fine. I have stored all-shortening BC on the counter for up to 6 weeks with no problems. I have read up to 3 months is OK.

It's the BEST.

I forgot to put away the extra and it stayed out for two days, it was still GOOD.

I've also frozen the some, taken it out to defrost at room temperature and it still works.

I love this frosting!
