Must have for peanut butter lovers!

These snack bars are delicious. My husband is also enjoying them (although I did not buy them for him or to share). They are also very satisfying. They are also great for that quick snack or lunch on the go. If you are a peanut butter lover, this is a must have because it is all the pleasure without the sugar.

I would buy again

I like these. I wish they were a little softer - they are a bit chewy. But the flavor is good and it’s a nice size bar.
