In the United States, both seasons of Adventure Time: Fionna and Cake are available to stream on HBO Max (formerly Max). The series is also listed through the HBO Max channel on Prime Video and on YouTube TV, though those routes depend on the subscription and package you have. The latest U.S. availability check cited here was July 31, 2026; streaming catalogs can change.
Where to stream both seasons
| Service | What to know | Best fit |
|---|---|---|
| HBO Max / Max | Direct subscription; both seasons were listed in the U.S. catalog. | Most viewers, especially if subscribing just to watch this series. |
| Prime Video Channels | Access is through the HBO Max channel, a separate subscription route. Ordinary Prime membership alone should not be assumed to include the show. | People who prefer Amazon billing or already use the channel. |
| YouTube TV | Also listed as an option, but confirm that your current package provides the required access before subscribing. | Households that already want a live-TV streaming service. |
The U.S. listings cited for this guide showed Seasons 1 and 2 on these services as of July 31, 2026. HBO Max and Max refer to the service during its 2026 name transition: Warner Bros. Discovery says the change to HBO Max retains the same programming, account, plans, and pricing. Check the service’s transition details.
Is it on Hulu?
Hulu’s Adventure Time catalog page surfaces Fionna and Cake, but that alone does not establish that a standalone Hulu subscription includes every episode. Current U.S. availability listings identify HBO Max/Max, the HBO Max Prime Video channel, and YouTube TV. If you already have Hulu, sign in and open the series page to confirm playback access before paying specifically for the show. A bundle or add-on may have different terms.
What does Max cost?
For U.S. subscribers, Max’s official pricing page listed these prices when checked in August 2026:

See Max’s current plan details before signing up, since prices and plan terms can change. If you want only this 20-episode series, the lowest-cost eligible monthly plan is generally the more flexible choice than paying for a year. Higher tiers may suit households that need more simultaneous streams, downloads, or supported 4K playback, but those features are not necessary simply to access the show. Resolution and feature availability depend on the title, device, and plan.
If you already get HBO Max through Prime Video, YouTube TV, or another provider, check before adding a direct subscription so you do not pay twice. The amount charged and how you manage the subscription depend on who bills you.

Can you watch it free, buy it, or get it on disc?
The latest U.S. availability check found no free streaming option and no separate digital purchase or rental listing for either season. That is a snapshot, not a guarantee that the options can never change. Max says most of its subscription providers do not routinely offer free trials, though promotions may appear. Treat a trial as provider-specific: check eligibility, length, and the renewal date at checkout, and cancel before renewal if you do not want a paid subscription. Max’s trial guidance explains the limitations.

How many episodes are there?
The U.S. listings show two seasons, with 10 episodes each—20 episodes total. Episodes typically run about 24–25 minutes. See the series listing and the Season 2 listing for current catalog details.
What to do if the show does not appear
- Search for the exact title, Adventure Time: Fionna and Cake, and open the series page—not just a trailer, clip, or storefront result.
- Confirm that your account and app are set to the country where you intend to watch. Streaming rights vary by territory.
- Check which provider bills your subscription. If you subscribed through a third party, you may need to authenticate through that provider or manage access there.
- If using Prime Video, confirm that the HBO Max channel is active. A Prime membership by itself is not the same as subscribing to that channel.
- If using a bundle, verify that your specific plan includes Max access; seeing a title in a catalog does not necessarily mean your plan can play it.
- Check profile restrictions, update the app, and reopen the episode page. Catalog data or rights can also change, so contact the provider if a season or episode is unexpectedly missing before subscribing again.
Max advises subscribers to check their account’s subscription area to see who manages billing and subscription changes. Max subscription management help.

- Optional: original Adventure Time episodes featuring Fionna and Cake.
- Optional: Adventure Time: Distant Lands for broader franchise context.
- Adventure Time: Fionna and Cake, Season 1.
