I was wondering if I put RI flowers on a BC cake if they will really melt. I have been told both that they will and that they won't. I have 2 cakes due the same day and would normally just do BC flowers the night before but with the deadlines and nature of the cake, that won't really work. I was gonna start doing RI flowers in my spare time and then just put them on right before delivery. So any input is greatly appreciated!! Thanks in advance.

Royal icing flowers do work on buttercream cakes. They don't actually melt but if left for 2 or 3 days they will soften. If you decorate a cake with them and then freeze they will definately soften from condensation from thawing/warming. They are fine when placed on room temp buttercream as long as the RI decorations are completely dry before being used.

Royal is fine if you let it dry and put them on your cake after the buttercream has crusted a little. You see it commonly on wal mart/ safeway cakes. They buy theirs in bulk and place them on when they are boxed for sale.

I have never had a problem with RI and buttercream...

same here, i have never had a problem with r/i and b/c. my r/i (anything )is always completely dry before i ues it on the cake.

Royal ising will not melt the instant it hits buttercream. I have actually piped royal on a crisco covered cake and the icing dried hard and worked just fine.

Once the icing is made, you have to worry less about the grease factor. It just won't mix up properly if you introduce grease in in the making. Same thing with Meringue made with egg whites.

The moisture in my opinion is more of a concearn. You don't want to put dried royal icing pieces in the fridge since condensation may form and that would melt the icing. I'd also avoid cake carries that lock air/moisture in too, for the most part.

Thank You All! I am much less worried now.
