Lunch Lady Recipe for Peanut Butter Bars

School Cafeteria Peanut Butter Bars

Have you ever made or eaten Peanut Butter Bars?  I have only made this recipe a few times {I forgot I had it} but the story behind it is an interesting one....well, maybe not interesting but there is a story.  

Peanut Butter Bars

I went to Catholic school.....kindergarten through 12th grade.  When I was in high school my friend across the street went to the public school and was really excited that her mom got THE recipe for Peanut Butter Bars {peanut butter fingers} from the school dietitian.  I smiled but had no idea what the big deal was until I tried these......oh.my.goodness!  Now mind you, my Catholic school had good food but I think this may have been considered too decadent for them to serve us....just a thought there.  Peanut Butter Bars

I made these on my own when I first got married and I think I may have made them one other time when my oldest son was a little guy.  A few weeks ago I was going through my old recipe box {does anyone else have one or is everything online these days?} and I came across some great recipes~ and this one was the first one to make it from the typewritten index card to the blog.  How exciting {I'm a nerd....to me, this is exciting!}.
