I'm planning a birthday cake/birthday creation that might involve cake pops. While I've never made a cake pop before I understand the technique and think it would work well for the occasion. My question, though, is how freezable they are. I don't anticipate any problems caused by mixing the cake and icing together, molding it, and then freezing it on a stick before usage, but I'm wondering whether whatever I dip it into--likely melted colored candy melts (but perhaps either dark chocolate or white chocolate) would discolor or fade in the freezer for two weeks. Anyone have any ideas about this? Also, I'll probably dip the cake pops in some sort of topping (be it candy melts, dark chocolate, or white chocolate) and then decorate it with something like colored candy melts or colored white chocolate, colored with paste food coloring or oil based food coloring for candy decorations. So, they won't just be a solid color but instead will be a base color covering the cake and then decorations in color on top of that. To give you an idea, it will be decorated to look like a mushroom from the Mario Bros. games...so whites, reds, greens, etc. with a likely base coat of either white chocolate or white candy melts.
Also, instead of or possibly in addition to the cake pops I might use fondant to make shapes that will be decorations for the dessert. The fondant will definitely be colored, and I'm not particularly concerned how it will taste due to what I'm using it for (it is pure decoration and not something I anticipate people eating). I'm hoping to deal with making the decorations with the fondant two weeks ahead of time. Will the shapes be okay in an airtight container for about two weeks? Will I have any problems with the colors fading or bleeding? Will it stay reasonably soft it is covered?
Sorry for the cryptic questions...I'm still in the planning stages of this dessert and am going on vacation until the day before it is to be presented to the birthday boy. I'm just trying to get a feel for which techniques will allow the most work to be done before I leave. Thanks!
