I made myself this cake for my birthday. It has four layers, poured one on top of the next and baked together: white, yellow, light chocolate and dark chocolate. (Since it’s rock-themed, I wanted it to look a bit like geological strata.)
After baking the cakes themselves, I coated the tops with melted chocolate chips, and set the crystals!
They are sugar crystals, created by dissolving tons of sugar in a bit of water on the stove
, adding food coloring, and letting it sit in bowls for a few days, until a crust of rock candy had formed over the surfaces of the bowls. (I had been hoping to make geodes, and I’d lined the bowls with lightly greased aluminum foil, but unfortunately nothing crystallized on the insides of them.)
