I'm sure this has been asked, but I can't seem to hit the right words/phrases in the search, so I'll just ask!
I'm working on setting out and coloring icing for 2 cakes this weekend - I'm doing 2 cakes at once (Yikes!!) so I'm trying to plan ahead. These will be iced in buttercream but detailed with fondant. Here's where I need the help! About how much icing does it take to JUST ICE, not decorate, an 8in layer? How about a 10in layer? I know it will vary, but I just need a ball park!
for a ball park, check out the wilton chart here. Should get you pretty close.
I use 2-2.5 cups to fill and ice an 8" round torted into 3 layers. Probably 3-3.5 for a 10"
