How to revive my buttercream frosting?
I made a cake and buttercream frosting 6 days ago for my niece's 1st birthday party. Unfortunately the party was rescheduled because the little one wasn't feeling well.
I froze the cake and defrosted it, and it looks fine, but Im worried about the frosting.
The icing is made from butter and powdered sugar- Ive had it out of the fridge for 3.5 hours and it less cold but still firm. How many more hours will it probably need outside the fridge to get smoother and warmer? Should I add some milk?
If you have a food processor, throw it in there and spin until smooth. It will become creamy again - no problem. Otherwise you can just re-beat it with an electric mixer, which will do the same thing basically (just a little more effort). Frosting - especially a simple buttercream with no egg or other perishable ingredients - will last almost forever.
Make sure it is at room temp and then rebeat it. If it seems too thick add whipping cream or milk, but you shouldn't need to. American buttercream can last a long time in the fridge.
