What is an ube wobble cake?

An ube wobble cake, also called a jiggly cake, is a Japanese-style sponge that gently wobbles when moved, flavoured with ube, a purple yam. Ours is handcrafted in London, soft, cloud-light and delicately sweet.

What does it taste like?

Gently sweet, with a mellow, nutty, vanilla-like ube flavour and an airy texture that is lighter than most cakes.

Where does the purple colour come from?

The purple shade comes from ube, a purple yam native to the Philippines.

How is it different from your Ube Chiffon Cake?

The Ube Chiffon Cake is layered chiffon finished with whipped ube cream. The Ube Wobble Cake is a jiggly, soufflé-style sponge that wobbles when moved.

No. Our wobble cakes are made without cream cheese, giving a pure, cloud-like sponge.

Product Description

A Taste of Japan, Reimagined by Mooies

The Japanese Ube Wobble Cake is a Japanese-style jiggly sponge, handcrafted in London and flavoured with ube, the purple yam loved across Asia. Each slice is soft, delicately sweet and airy, with a sweetness that lingers quietly.

The Craft

Unlike a traditional sponge, a wobble cake is carefully aerated, then steam-baked low and slow for over two hours until it turns feather-light and trembles with elegance. Ube lends a gentle sweetness, fragrance and its signature violet shade, so each cake is as much a couture sculpture as a dessert.
