OK, I'm on vacation (yea!) and I'm playing cake this week. I haven't done many stacked cakes so I'm working on a 3 tier square stacked design. The stacked cakes need to be the same size as their boards. I don't know how to ice a cake that is the same size as the board. How do you do that? I don't want any of the board to show. I just gave up on my smallest cake because I couldn't ice it. I guess my board was too small.
I haven't done that many stacked cakes either. I'm still learning. but, I have always used the same size board,(maybe a bit smaller) as the cake and iced over the cake board. I always put a border on so if there is any board showing it will be covered by the border. hope this helped
usually, the board should be the same as the base of the cake layer (for between the tiers). I put that on a turntable or movable surface. Ice the cake to cover the board, or if there is a significant border, you can just ice down to the board.
when you go to stack them, pick the layer up with a large spatula under the board. I have an extra large one just for this. or lift it from the turntable and use your fingers.
The bottom tier should be on a board no smaller than 2" more than the largest tier.
