I've never had a circus cookie but this juice reminds me of the pale, frosting-heavy cookies sold at bake sales. Maybe that's what a circus cookie is? If so, the flavour is on point.
On inhale, I get a sweet, sugary, almost vanilla cake flavour, and on exhale I get a sugary white/pink frosting, similar to the frosting on Pop Tarts.
The flavour description is on point. I never liked these cookies (I like the juice version a lot more though) but the juice is decent. Would be better if there was more depth, maybe in the form of a fruit frosting flavour.
(Also, as a side note, the business that makes this is called Puff Labs, same one that came up with the Psycho E-Liquid and Strange Fruit lines.)
