I just finished my first photo cake. I am pleased with the way it looks!!
I was expecting the icing sheet to 'melt into' the buttercream on top, though, and it appears to have a leathery or firmer surface where the picture is. Is this normal, or did I screw up?
The buttercream was fairly soft, and I also smeared a little piping gel on the top of the cake, prior to laying the photo, just to ensure it would adhere correctly...
That is normal, it does take awhile for the sugar sheet to "melt" into the BC. It will remain more like a fondant, but due to it being so thin it won't separate from the BC like fondant will, the longer it sits.
will it be difficult to cut into?
