Crumbl Spoilers September 2026: The Full Month, Week by Week

September has been one of the most eventful months on Crumbl’s calendar all year. Crumbl Spoilers September 2026 opened with a long-rumored gaming collaboration, moved into a second brand partnership the following week, then pivoted into a comfort-flavor lineup topped by the richest item of the month so far, and now heads into Crumbl’s own birthday week. Here’s the complete month, broken down week by week, with confirmed lineups clearly separated from leaks and speculation. Updated as of September 15, 2026.

Are the September 2026 Crumbl Spoilers Official?

No, as of today (September 15, 2026), only three of September’s five weeks are officially confirmed, and even those are only “official” retroactively once Crumbl’s Sunday reveal happens.

Most spoilers come from fan communities, social media discussions, and early insider reports that have successfully predicted previous weekly lineups. However, Crumbl can make last-minute changes, so any leaked menu should be treated as unconfirmed until Crumbl officially announces the lineup.

Week 1: August 31 to September 5 (Confirmed)

Week 2: September 7 to 12 (Confirmed) — Little Debbie Collaboration

The second week of September 2026 brought a genuine licensed partnership with Little Debbie, confirmed by the registered trademark symbols on the official menu. Again, every item landed at $4.49.

Week 3: September 14 to 19 (Confirmed) — Comfort Flavors

The current lineup skips the collab format and leans into comfort and nostalgia flavors instead. Every item is priced at $4.49:

This is also the heaviest week of the month so far by a wide margin. The Dubai-Style Chocolate Brownie at 1,010 calories is the single richest item confirmed in Crumbl spoilers September 2026, and the Ice Cream Cake Sandwich Cookie isn’t far behind at 950.

Week 4: September 20 to 26 (Confirmed) — Crumbl Birthday Week

This is the one to plan around. The Crumbl Spoilers September 2026:

Week 5: September 28 to October 3, 2026 (90% Confidence) — Comfort/Cozy Theme

Rumored New Flavors for Fall 2026

Separate from any single week, these names keep coming up in fan discussion as likely debuts once the calendar fully turns to fall:

None of these are confirmed. They fit Crumbl’s pattern of introducing one or two brand new recipes alongside returning favorites each week, but that’s a pattern, not a source.

Quick context before the breakdown, since it explains why some “leaked” lists are only half news:

The actual news each week is almost always in those four rotating slots, not the six that never move.

Frequently Asked Questions

Is the September 2026 Crumbl lineup fully confirmed?

Partially. Weeks 1 through 3 (August 31 through September 19) are confirmed and already happened. Week 4 (September 21 to 26, birthday week) is leaked but not yet officially confirmed. Week 5 (September 28 onward) is early speculation only.

How often does the menu actually change?

Every week. Four rotating flavors change each Monday alongside the six permanent classics, with the official reveal happening Sunday evening.

Is there a birthday week deal?

Unconfirmed for 2026, but Crumbl has traditionally run a 6-pack for the price of a 4-pack during birthday week, usually on Wednesday.

Why did the Minecraft collaboration leak twice?

It was rumored for August 24 to 29 first and didn’t happen that week, then it was rumored again for August 31 to September 5 and did happen. It’s a good example of why a missed prediction doesn’t mean the rumor was wrong, just early.

Will pumpkin flavors show up before October?

Likely in some form given the pattern of recent years, but nothing specific is confirmed for the remainder of September.

Final Thoughts

September 2026 turned out to be a genuinely packed month: a Minecraft collaboration to open it, a Little Debbie partnership the following week, a comfort-flavor lineup currently running (and the richest item of the month at 1,010 calories), and Crumbl’s own birthday week coming up next with a new Pink Sugar Cookie Cake and a possible multipack deal. The back half of the month, heading into Halloween season, is still mostly rumor at this point.
