The picture on the Amazon product page at this writing has an ingredient list that explicitly lists milk products, however that is the old recipe. The current recipe (May 14, 2024), which you can find on the Rip Van website, does *not* include milk products. The label on the box I received warns that it "may" contain milk because the equipment they use is probably also used to produce milk-containing products. So if you have a lethal dairy allergy or feel very strongly about only supporting 100% vegan companies (not sure how one could determine that), then you might want to avoid it. I'm a pretty militant vegan, but the way I see the world, there are functional limits. (Did you know there is gelatin in your tires? The list goes on...)That said...I love Oreos, but I'm very conscious about blood glucose because I wore a CGM for a month once and it completely changed my relationship to carbs. It's like the first time you run your car out of oil and learn the consequences of what you've done to a very expensive piece of machinery. You'll *never* do that again. Similarly, the idea of pegging my blood sugar is now an anathema to me. I'm not diabetic (yet) but I have to live in this body for the rest of my life, and I want it in the best shape possible. Alas, I have a major sweet tooth, so I have a hobby of sorts, where I'm constantly trying to substitute xylitol, erythritol, Stevia, or allulose into various recipes. I also occasionally buy products like these cookies just to assess the state of the art.Like I said in the title, I would call these about 75% of the experience of Oreos. I enjoyed eating them, but I have to admit they taste a little "off" and there is a persistent aftertaste, probably from the Stevia. (In my experience, allulose has no aftertaste.) So if you are a person whose values taste over nutrition or general health, or would prefer to eat one Oreo (who can do that??) instead of four Leos, I guarantee you'll regret buying them. However, if, like me, you want to live a long and healthy life and still have the "idea" of Oreos from time to time, I think you'll appreciate them.The nutrition facts say these have about 1/4 the "sugar" of Oreos; that number is probably derived from the corn and sugar cane fiber, though allulose is also technically a "rare sugar" so perhaps that is included in the total? In fact, it might account for most of it. Of course, neither allulose nor Stevia raise blood sugar, and allulose also reduces the postprandial glucose spike from standard carbs, so you have to take that into account. Unfortunately, I'm not currently using a CGM, so I can't make an empirical determination.Subjectively: I normally don't become aware that I'm cramming true Oreos down my throat until I eat at least eight of them because that's the point where my stomach starts to get a little upset. Conversely, I ate one package of Leos (four cookies, slightly smaller than Oreos) and I don't want any more. I'm guessing that is probably due to a combination of the lack of an addictive response and the aftertaste.I don't yet know whether I will buy these again. We'll see how I feel when the box is gone. My rating isn't just about taste, but includes function. I gave four stars because I believe there is still room for improvement. I'll also be watching to see how they modulate the recipe going forward. They're going to be hard pressed to find something as sweet as Stevia for the filling, but that's probably the only way to get rid of the aftertaste. Maybe they could replace the Stevia with the less sweet allulose and add more fat to compensate, i.e. make them "double stuff." Anyway, I'm sure they're aware of the deficiencies and are working on ways to make them better. It's not an easy problem to solve.
