I was wondering if someone could tell me how long your meant to let your buttercream filling and crumb coat set for before covering the cake in fondant.
I used buttercream for the first time on the weekend and let it set for a few hours at room temperature but when i put the fondant on you could see where the filling inside the cake as at it seemed to soften a litte.
Should i be putting it in the fridge and letting it set for a few hours???
Any advice would be appreciated as i have to make another cake for this weekend.
