Steamboat Willie Cake Set & Sweets Drink Review — Hyperion Lounge, Disney Ambassador Hotel (Tokyo)

Hyperion Lounge at Disney Ambassador Hotel in Tokyo, Japan serves seasonal and event-themed Cake Sets, Special Sweets Sets, and Sweets Drinks throughout the year.

Some park-event-themed menu items require Priority Seating reservations, but the Hyperion Cake Set series and the Sweets Drink are walk-in, no reservation needed. The Hyperion Cake Set series in particular is consistently popular thanks to its photogenic, super-cute designs.

This post covers the Steamboat Willie–themed Hyperion Cake Set and Sweets Drink, both available starting in February 2026.

The look alone made me happy — and they both pair chocolate with citrus for a sweet-tart combo that’s genuinely delicious. Let’s get into it.

Steamboat Willie Hyperion Cake Set — Quick Overview

This round of the Steamboat Willie Hyperion Cake Set is “Chocolate Cake with Raspberry Ganache & Yuzu and Orange Mousse.” Coffee or tea is included, and you get free refills as long as you stick with the same drink type.

The Hyperion Cake Set series isn’t covered by Priority Seating — you can just walk in to Hyperion Lounge and order it. That said, daily quantities are limited, so going early is your best bet.

The Steamboat Willie–themed “Chocolate Cake with Raspberry Ganache & Yuzu and Orange Mousse” runs as a limited-edition item from February 2026 through April 15, 2026.

Steamboat Willie Hyperion Cake Set — A Closer Look

The cake design recreates one of Steamboat Willie’s iconic moments: Mickey at the helm of the steamboat. Even the waves are recreated — really impressive. And since it’s a chocolate cake, the whole thing reads in monochrome, just like the original short — a great touch.

For the breakdown: the base is chocolate cake, with raspberry ganache sandwiched in the middle. The wave layer above is made of lactic-acid-bacteria jelly. The steamboat itself is yuzu-and-orange mousse, coated in chocolate. The smokestack is a roll cookie coated in chocolate, filled with Pearl Craquant (small ball-shaped chocolates with cereal inside). Mickey and the smoke are made of sugar art, while the film strip is chocolate.

Playful Design You Can Actually Eat

The smokestack is a chocolate-coated roll cookie — and inside, it’s filled with Pearl Craquant chocolates. It’s like a candy-form recreation of the smoke billowing from the smokestack in the original short. I got way too excited about this.

The other piece of inspired design is the waves, made from lactic-acid jelly. The glossy jelly catches the light just like sunlight on rippling water — it’s seriously well-executed. And since the original short is monochrome, doing it in plain white feels just right.

I’ll get to the taste shortly, but if “lactic-acid jelly” sounds like an odd pairing for cake, I get it — it actually matches surprisingly well, and it’s delicious.

Two Tartness Notes That Lift the Chocolate

Citrus tartness from the yuzu and orange mousse, plus berry tartness from the raspberry ganache — both pair beautifully with chocolate. The sponge cake is a low-sugar cocoa base, which lets each tartness note shine. The yuzu and orange mousse leans bright and refreshing, while the raspberry ganache reads sweet-tart since it has chocolate folded in.

Thanks to those tart notes, nothing here feels cloying — and the chocolate cake itself is dialed back on sweetness too. Easy to keep eating, and genuinely delicious.

A Texture Playground

Hyperion Lounge cakes are known for layering different textures, and this one keeps the streak going.

The biggest standout is the lactic-acid jelly — visually striking and texturally smooth and bouncy. It pairs surprisingly well with the cocoa cake. Flavor-wise it’s lactic, so think along the lines of Calpis (a popular Japanese yogurt-style drink) — it adds a bright, refreshing note to both flavor and texture.

The next standout is the crunch. The roll cookie smokestack and the center of the raspberry ganache both deliver a crisp bite. Mousses and ganaches lean creamy or sticky, so adding a crunch to the mix bumps up the satisfaction factor.

On top of that you get the snap of the chocolate film and yuzu-and-orange mousse coating, the airy fluff of the mousse itself, and the little pops from the Pearl Craquant chocolate balls — the whole cake is genuinely fun to eat.

Sweets Drink — Quick Overview

Like the Hyperion Cake Set series, the Sweets Drink isn’t covered by Priority Seating — just walk in to the lounge to order. Daily quantities are limited here too, but the Sweets Drink tends to stick around longer through the day than the cake set.

Heads up: the Sweets Drink runs through April 7, 2026 — about a week earlier than the cake set. Plan accordingly.

Sweets Drink — A Closer Look

This drink leans on the contrast between orange tartness and chocolate sweetness. The presentation is gorgeous — you’ll want to just stare at it for a moment.

Top to bottom, the layers are: marmalade, sliced orange, fresh cream, chocolate ice cream, more orange, chocolate whipped cream, then the white section (white chocolate syrup and cream cheese frozen drink), and finally marmalade at the bottom.

It comes with a parfait spoon and a wide straw, and the server told us, “Mix everything well using these two.”

…that said, I started by spooning straight down from the top, layer by layer, before mixing anything.

First up, the chocolate ice cream on top: bitter and rich — feels like high-cacao territory. The chocolate whipped cream below is more milk-chocolate and clearly sweet, a great contrast to the bitter ice cream above it.

Next, the white layer in the middle — arguably the main attraction. Spooning into it, the white chocolate flavor came through clearly. Surprisingly, I didn’t taste much cheese at first, but the bottom of the white layer was full-on cream cheese. It looks like a single layer but is actually two stacked together.

Diving the spoon into the marmalade at the bottom and pulling some up, the orange, cheese, and white chocolate flavors mix together beautifully — incredibly tasty. Since it’s a frozen drink, you can scoop and eat it like ice cream or a shake.

Eating it together with the orange slices on top adds bright, juicy fruit notes — also excellent.

After spooning through about a third of the way, I gave it a good stir with the straw and drank it. Once mixed, the cream cheese flavor leads, and the chocolate just rounds it out with sweetness. Every now and then a refreshing orange note hits — the flavor evolves as you drink, which is really fun.

Both approaches — spooning layer by layer and stirring it through — were tasty, so either works. Personally, I preferred the unevenly-mixed middle ground: spoon some, stir lightly, drink, repeat. You get more flavor variation that way.

Final Thoughts

So that was a look at the Steamboat Willie–themed Hyperion Cake Set and the chocolate-and-orange Sweets Drink, both at Hyperion Lounge inside Disney Ambassador Hotel.

The cake doesn’t just recreate Steamboat Willie’s monochrome look — it’s also full of the playful spirit of the original short. Flavor-wise, the two tartness notes work beautifully against the chocolate, making for an excellent chocolate cake.

The Sweets Drink is also a winner: orange, chocolate, and cream cheese complement each other perfectly. There are multiple ways to enjoy it — eat the layers as-is, or mix it through — which adds to the fun.

Both items center on chocolate paired with orange, with that ideal balance between sweetness and brightness. Quantities are limited, but no reservation is needed — if you’re nearby, definitely stop in.
