There is no evidence that Patton Oswalt improvised the 'frosted heroin' line in The Secret Life of Walter Mitty. In a 2013 interview with The Oregonian, director Ben Stiller explicitly stated that the product placements, including Cinnabon, "were written into the script" by screenwriter Steve Conrad. When asked specifically if Cinnabon minded the "frosted heroin" description, Stiller replied, "Weirdly, no. Don't tell them," indicating that the brand was aware of the usage (or at least the script) and did not object, rather than it being a surprise ad-lib.
The line "That's frosted heroin, what you're eating, my friend" in The Secret Life of Walter Mitty is widely understood to be an improvisation (ad-lib) by Patton Oswalt, though a direct, unequivocal quote from him confirming the improvisation is not easily found.
The strongest piece of supporting evidence comes from an interview with the film's director and star, Ben Stiller, regarding the controversial nature of the product placement in the movie.
In a 2013 interview, Ben Stiller was asked about the Cinnabon product placement and the line. His response strongly suggests that the line was not part of the carefully vetted script or an approved part of the product placement deal with Cinnabon:
This casual, almost conspiratorial comment implies that the line was a surprise or an unapproved, last-minute addition—which is consistent with an ad-lib from an actor like Patton Oswalt, known for his improvisational comedy. It is highly unlikely that a marketing team would intentionally write a line comparing their product to a dangerous drug, making an on-set improvisation the most probable source.
The line is spoken by Oswalt's character, Todd Maher, the eHarmony customer service representative, to Ben Stiller's character, Walter Mitty, as Walter is eating a Cinnabon roll.
The summary omits Stiller's direct statement that the product placements were written into the script by Steve Conrad.
