Any advice on how to prevent buttercream icing from sticking to the cake board when separating stacked tiers? No matter how careful I am when I remove a tier, all of the icing pulls up from the tier below. Thanks.
I use dowels in my cakes to help with the weight of the next cake and to prevent the icing from coming off on the cake board above it. Just make the dowels a slight fraction longer and that may help you.
I use a piece of waxed paper cut a little smaller than the tier it will sit under. When it's time to cut the cake just carfully peel it off. You can still use a little RI or BC on top of it for the board to stick to.
I have used tyty's suggestion and I often just sprinkle powdered sugar over the area where the cake board will rest. hth.
