These chocolate and vanilla marble cakes are a beautiful blend of two classics — soft vanilla sponge swirled with rich chocolate batter to create that signature marbled pattern. It’s a simple, nostalgic bake that looks impressive without any fuss, perfect for afternoon tea, celebrations, or an everyday treat.

Every slice gives you the best of both worlds: light, buttery vanilla and deep, cocoa‑rich chocolate in one delicious bite. You could even serve this with some creamy custard!
