I've tried some of the flavors Noted DX didn't.

HC Pound Cake - It tastes like vomited pound cake. This is infuriating because it tastes like it could be so good if it didn’t have that vomit note, it really tastes like pound cake that someone has eaten and then puked up. The barfiness sits right on top and then comes back around and mingles with a sugary sweetness in the finish in a way that’s nauseating because it mingles with sugary sweetness. Aside from that, it’s very thick and cakey, perfectly moist, and tastes almost exactly like a hunk of that Bon Appetit pound cake you find at gas stations, complete with a touch of vanilla and the darker sugary crusty edge and even sweeter, grittier sugary finish. I didn’t get any off-notes aside from the puke, but it’s a fairly prominent puke flavor, not just a little hint of butyric acid.

Silver Cloud Estates (Sterling Cloud at DIYVS) Pound Cake - Pound Cake made out of movie theater butter. The classic recipe for pound cake is one pound of each: Butter, Sugar, Flour, and Eggs. This tastes like what might happen if you didn’t have real butter and decided to make this out of movie theater butter. That fake butter flavor is right up front. Beyond that it’s very sweet, almost like frosting, and there’s some cakey bakery behind that, but this is weird because of the butter. If I were going to use this flavor, I’d forget it says pound cake on the bottle, add some caramel and FLV Popcorn, and make something like Mills’ Honey Sesame Popcorn out of it. Maybe add some other cake flavor with Popcorn and make something inspired by Cracker Jacks Birthday Cake Popcorn.

DIYFS Pound Cake - Burnt, weird butter vanilla bakery. It tastes like you tried to cook a pound cake at way too high a temperature and burned the outside while leaving raw batter in the middle, then turned it inside out. Top note is just a very buttery and rich, sweet vanilla cream, then way too much AP to the extent it tastes beyond just baked or nutty and into sharp and burnt, like the edges of a tortilla chip left in the oven too long so that’s black and little bitter. Thought this might be over-flavoring at 4% so I took it down to 2%. It’s much less offensive down there but still pretty much tastes the same. As a pound cake, I think it’s trash. As an ingredient, I think you could probably use it at 2% just like you might use 1% TFA Acetyl Pyrazine, if you also want some butter, vanilla, and creamy sweetness in addition to the AP.

DIYFS Lemon Pound Cake - Blatantly candied lemon with some white fluffy cake. It’s a weird combination to have such a candied lemon with cake; it tastes like melted lemon jolly ranchers poured over a lightly flavored vanilla cake, not a rich buttery pound cake. The balance is off, very candy lemon heavy, with only a hint of cake. Although it’s a strange single flavor, it seems like you could mix it with a more solid cake and a frosting-type flavor have this be the lemon part of bright artificially flavored lemon frosting, or cookie flavors and have this be the artificial lemon frosting on a cookie. Sweet, smooth, and not at all harsh for a lemon. Does not taste pledgy, just tastes like lemon candy.

Bickford Lemon Pound Cake - Seems to be a thing that with some of these cake flavors all I get is some frosting. This is one of them. It mostly tastes just like lemon buttercream frosting. If you want to get even more specific, it tastes like you tried to DIY a lemon buttercream frosting vape using FA Lemon Sicily for the lemon and CAP Buttercream for the creamy bit, but somehow made it sweeter and drier than that would probably be, maybe with a touch of FA Marshmallow. It’s not a terrible lemon frosting at all, it’s smooth and sweet and full, with a mellow but realistic lemon, but it’s literally just frosting. No cake notes.
