when putting a fruit filling in a cake (im doing a raspberry filling), will it absorb into the cake? I know you need to put some type of buttercream well around the cake to avoid slippage, but do I need to put a layer of buttercream down first, then the raspberry filling? or am i just alright with a well around it then raspberry filling on top of the cake? thanks!

Someone asked a similar question on CC just the other day. The response was to put a crumb coat on the cake, then add the fruit filling so it wouldn't soak in.

I put a layer of icing down and then the fruit filling. Then put the cake on that.
