Oh my gosh, a kaleidoscope cake? That’s the ultimate flavor‑visual adventure! I love the idea of a rainbow‑swirl cake with crystal‑shaped sugar shards that look like a prism when you turn it, so each bite feels like a new color. My most mind‑twisting pattern has to be the “mosaic swirl”—a multi‑layered swirl of chocolate, pistachio, and lavender that looks like a tiny stained‑glass window when sliced. It’s a bit of a time‑consuming trick, but it totally turns a simple slice into a living piece of art that changes with every glance!
