How long does American buttercream(wilton) last at room temp? i made some last weekend and am hoping i won't have to make more. my recipe only has one stick of butter and the rest is hi ratio. Thanks!
Hmmm...up to you. I would eat it and probably serve it to my family but I wouldn’t put it on a cake I was selling to a customer...
ok. i figure it should be ok but wasn't sure. i only used 1/2 c for a double batch of the wilton recipe. so 3 1/2 c hi ratio and 1/2 c butter. ugh! i made a lot too
For future knowledge you can freeze it -- when it's fresh :)
I always keep my left over frosting in the refrigerator or freeze it. I am anal retentive and leave nothing at room temp.
I would just throw it in the fridge. Unless it is has been applied to a cake for personal consumption (because I don't like cold cake and when I want a slice of cake I want it right this second and don't have the patience to let it warm up ) I wouldn't leave it at room temp. When you need to use the frosting just pull it out of the fridge and let it soften, then give it a quick re-whip and it should be good to go.
I warm my cake slices in the microwave for about 10 seconds. Perfect.
