This is the amethyst cake baked and decorated by kitchen sorceress Rachel of Intricate Icings in Denver, Colorado. It looks like there's a massive geode inside. There isn't though, it's all sugar candy that LOOKS like a massive geode. You know I remember when I was a kid I was fascinated by geodes and I'd collect rocks in my backyard then bust them open with a hammer. They were all just plain ass boring rocks on the inside though, and that's why I'm not a geologist now.
Keep going for a closeup and a short video showing the depth of the geode.
Thanks to becca b, who wants a tiger's eye cake. OMG tiger's eye used to be my favorite too!
