Decorating the birthday cake and fairy cakes for Dd bday party on sun morning. Today is literally the only time I have to do it (new baby, mum coming to hold him today while I make cake). I am using Betty Crocker ready made spreadable buttercream style icing and Dr oetker cupcake coming in a spray aerosol. (Yes I know icing easy to make but I have a new baby!).
If I do the icing today and put in airtight containers will they be ok for Sunday morning? Need them to be a) edible and b) not kill anyone. Taste I am less worried about.
