I will eat nuts all by themselves (specifically, I like almonds, cashews, pistachios), but not IN things, generally. My peanut butter must be smooth (but I actually prefer 100%, no sugar added) and I typically will not eat baked goods with nuts unless very finally chopped (I like most baklava-type pastries and rum balls, for instance). For me, it's the unexpected crunch I think, though as an adult I learned to appreciate them more (I now add slivered almonds to my salads), so she too may outgrow some of this. If she'll eat a handful of nuts, it's an excellent protein snack, though it may take some trial and error to find ones she likes.
