Taste like the vanilla flavor with added pbfit powder. When I use the vanilla powder I occasionally add pbfit to it and this tastes just like it without the additional product in the mix. However, adding the pbfit does add more protein (but it also adds more carbs and calories if you care about that). I wish this was an even stronger peanut butter flavor but it’s still good. Way way way better than the grossly overly sweet and didn’t taste anything at all of peanut butter Quest peanut butter flavor. I think if I feel like adding extras, I’ll try this with pbfit to see if it gets the strong Jiff like flavor I’m looking for. I feel, as it is, the peanut butter flavor will be completely lost if I wanted to add fruit for a pb and j shake or chocolate almond milk for a pb cup shake vibe. I think it’ll be tastier and cheaper to keep adding pbfit to the vanilla flavor I can get cheaper at Sam’s club for a more intense peanut butter taste. Especially since I don’t care about calories or carbs.
