Only Murders In the Building Season 3 delivered a lot: Musical numbers from Meryl Streep and Steve Martin, reminders that Martin Short and Paul Rudd are treasures to be protected at all costs, and now, a viral dessert that you can snag for yourself for a limited time. (Just a warning: If you're not caught up, there may be potential spoilers ahead!)

While Oliver Putnam's dip obsession took center stage in Season 1, it was Schmackary's  Lip-Schmackin' Good Cookies that stole the show in the third installment of the Hulu hit.

In Season 3, Rudd's character, Ben Glenroy, has a serious weakness for sweets, and he scarfs down a gifted cookie with the logo of Putnam's production, Death Rattle, before opening night. His sweet tooth leads to his character's demise, and if we're being honest? It seems worth it.

Schmackary's is name-dropped several times in the series as being the "official cookie of Broadway," and the source of several desserts that Glenroy has trouble resisting. The frequency of its mentions actually took Schmackary's founder and owner Zachary Schmahl by surprise.

"When we tuned into the first episode, my jaw literally dropped to the floor. I didn't know how involved we would be in the storyline," Schmahl told TODAY. "But then as we kept watching the show, and every other episode, they were mentioning our name."

Now, Schmackary's is offering "Only Cookies in the Building" 4-packs.

The Death Rattle Razzle Dazzle features four of their Death Rattle Velvet cookies, which have a red velvet base with white icing and a red rattle, just like the goodies that appeared on OMITB.

"We love a little cheeky humor," Schmahl told TODAY. "When we put the cookie out on the counter, we were sprinkling powdered sugar on one every once in a while. We told customers, 'You might get the Ben Glenroy cookie,' and it was hilarious! People were even asking for the one with the 'poison' on top."

You can also get a Drop Dead Delicious 4-pack, which features one each of Glenroy's guiltiest pleasures: Classic Chocolate Chip, Cereal Killer, Cookies & Cream and Death Rattle Velvet.

Each OMITB-themed 4-pack is available for shipping nationwide through Halloween, and if you're lucky enough to live in New York City, you can also pick them up or get local delivery from their Hell's Kitchen location.

Death truly never tasted so sweet.
