I would like to make a cake with a filling inside but don't really know how much I should be using. I understand how to make the dam of buttercream around the cake edge then fill in the center with the filling. But how much do I use? Do I just splat some on until it meets up to the edge of the dam or what? I'm afraid it will be too much and just seep out the sides when I put the top layer on.
Is there anywhere that tells how much filling to use for each cake size?
You want your dam higher than your filling. If the filling is even with or higher than the dam, it will seep over when you put the top layer of cake on. I do not have any exact measurements of how much filling for certain size cakes...hopefully someone else has a chart that you can use.
