Cinnamon Toast Crunch's Chamoy Mega Cereal Is Back In Stock After Selling Out in Six Days

Cinnamon Toast Crunch's own store listed the Chamoy Mega cereal as Out of stock from September 6, re-checked on September 11, 13, 14, 16, 18 and 20, 2026. The cereal went on sale on August 31 at 12 p.m. CT, which put that first run at roughly six days.

Checked again on September 24, the listing had changed: the out-of-stock badge was gone, the page carried a quantity selector and an active Add to cart button, and the structured data on the page gave its availability as InStock. The price was unchanged at $4.99. Re-checked on September 28 and again on October 1, the listing still shows $4.99 with an active Add to cart button and no out-of-stock notice, so the second window has now stayed open for at least a week.

General Mills has published nothing about a restock — no announcement, no quantity, and no end date. The only thing the company has ever said about how long it lasts is "while supplies last", which is what made the first sell-out possible to miss and makes this second window just as hard to predict.

The easiest thing to get wrong about this collaboration is assuming both halves are the same product. They are not.

Chamoy Mega Cinnamon Toast Crunch CINNADUST Flavored Chamoy Sauce is the other direction of the same deal — the cereal's CINNADUST flavour put into Chamoy Mega's sauce. General Mills said it would go on sale on Sunday, September 13 at 12 p.m. CT, on Chamoy Mega's Amazon storefront rather than the cereal site, also while supplies last.

That date passed on September 13. This page does not state that the sauce went on sale, because that has not been established: the Chamoy Mega Amazon storefront could not be checked on this update either, and could not be checked again on October 1, and General Mills has published nothing after the August 27 announcement to confirm the drop happened, slipped or sold out. The announced date is a plan the company stated, not a record of what occurred, and the two are not the same thing.

One detail is worth flagging for anyone going to look. The Takeout gives the sauce's date as September 14 rather than the September 13 in General Mills' own announcement, and says it is sold on TikTok Shop as well as the Amazon storefront. The company's date is the one this page treats as authoritative, but the extra channel is not in the announcement at all, so a reader who cannot find the sauce on Amazon has somewhere else to check.

No price has been published for the sauce, so none is printed here, and General Mills has announced no end date for it either.

Cinnamon Toast Crunch describes the cereal as its usual squares blasted with real cinnamon and sugar, then finished with a chamoy-inspired twist. Chamoy is a Mexican condiment built on fruit, chilli, lime and salt, and Chamoy Mega is made in Mexico by Mega Alimentos; General Mills calls it the #1 chamoy in the U.S. and Mexico.

General Mills quotes Megan Brooks, Business Unit Director for Cinnamon Toast Crunch, saying the collaboration gives cereal buyers "a playful way to experience that flavour trend" as sweet and tangy flavours turn up in more snacking occasions.

Foodbeast filed the launch under "swicy" — the sweet-and-spicy category that has been pulling in cereal, sodas and sweets through 2026. A six-day sell-through on a direct-to-consumer drop is a data point for that, though it is worth being clear about what it does and does not show: General Mills has not published how many pouches it made, so "sold out" measures the size of the run as much as the size of the demand.
