Peanut butter bars

I received this recipe from a church youth leader when I was a teenager. It reminds me of the peanut butter bars the lunch ladies used to pack in our sack lunches for field trips in elementary school. I have to make it every few months or else I miss it.

  8. I was having a craving for these and did a google search for a recipe. How funny that it found your blog! The world wide web just keeps getting smaller and smaller. It probably was reading about them here that started my craving in the first place, actually. I just couldn't remember what started it all. Off to do some baking.....(Thanks for the recipe!)

  9. I have these in the oven right now ~ just couldn't resist! Thanks for posting the recipe!
