Love them. They They went very fast at my church's cookie walk. They went even faster at home. They are so easy to put together that even a 5 year-old can do it. So how can the directions be confusing?


I made these bars. I did a slight variation when I found out I had no eggs so instead I used some oil in place of the egg. It came out just fine. I also couldn't decide if I wanted to use grape jelly or strawberry preserve so I split it in half and did both. Kids loved it . Would make it again. I think next time I would try it with chocolate and maybe some processed banana.


I love these bars. They are easy to make. I use strawberry all fruit. Yummmmmm This is a keeper.


This recipe is so good, I have tried several several types of jam and our favorite is Concord grape preserves. SOOOO good! Had NO trouble with the instructions. SO easy!


I made this recipe, doubling it, for a "mini" school reunion I attended over the weekend. I actually used some homemade cranberry jam/honey that I had made some time ago, the tartness of the cranberries made a perfect compliment to the peanut butter. Everyone raved about it and asked for the recipe so they can try it. I intend on making this receipe again and assume, for storing it for a good length of time, I can either refrigerate or freeze it. Thank you for publishing this recipe on your website....Carol W.


Undergoing Chemo and this is a great treat for my appetite. Has fruit, protein, and starch!!! Wonderful!! My husband is enjoying them too. I mixed several types of jam/preserves and added walnuts and creamy peanut butter since I cannot eat peanuts. Thanks for a great recipe!!!!


The recipe instructions do not make sense....
