These self-described "most expensive cookies in the world" are definitely not cheaper by the dozen.

Marketing itself as the "Rolex of cookies," Los Angeles, Calif.-based Last Crumb claims to be offering a $12,000 cookie collection.

But, the dubiously titled box of 12 treats are even more suspiciously being offered just for one day: April 1, 2024.

In what appears to be a bit of foodie stunt promotion, Last Crumb — whose dozen "core collection" box already carries a weighty $140 price-tag, says it is launching the "Twelve Thousand Dollar Collection," available to order for the one day only — on April Fool's Day.

The Los Angeles brand says the collection will feature 12 micro-batch masterpieces created by its head baker to "go above and beyond the pinnacle of flavor and peak of decadence."

The $12,000 collection is described as "a culinary concentration of the absolute finest confectionery creations that mankind, at this point, has ever known."

The LA brand's decadent cookies are often given as gifts — luxury gifts. Most of their cookie collections, including their Core Collection and Spring Riot Collection, sell for $90 per half dozen or $140 per dozen.

As for the Twelve Thousand Dollar Collection, Last Crumb isn't revealing what flavors might be included.

"Per Head Baker's clear instructions, we cannot tell you what's inside the box," a product description reads.

"What we can tell you is that this collection goes beyond your wildest imagination, shattering the boundaries of flavor and taste. Comprised of twelve expertly handcrafted, small batch, Michelin-quality cookies, baked with the damn finest ingredients we could source," the description continues.

"We're already known as the most expensive cookies in the world. With this launch, we're solidifying our status as the MOST most expensive cookies in the world. We think you're worth it. But you need to believe it, too."

Let the buyer beware!
