I like the idea of cutting into something that looks like a cake but it's crispy and crunchy all the way through. Sure, Trix tears up the roof of your mouth something awful, but it's worth it.
When I was a kid, the closest I ever got to decorating my own cake was a cookie and a little tube of gel icing. I had plenty of fun with just that. Imagine how awesome it would have been if we had edible paper back then? I can't say I'm not a little jealous of kids these days.
Finger jello is super fun even when it's only one color and just hanging out by itself. Taking the extra time to layer a whole bunch of colors in there takes it to a whole new level of snack innovation. I wonder how it tastes with all those flavors in one mouthful? Like a rainbow of fruit?
