These were just like the bars I had in elementary school growing up! My dough did not spread to fill out the whole pan, but it didn't matter. I broke up chocolate bars instead of using chips. I did half with milk chocolate, and the other half with semi-sweet. Everyone had their favorite! I had to eat 4 bars before deciding I didn't have a favorite! Everyone asked me for the recipe. Peanut butter bars are not known here in England (or they just aren't popular), but they were a big hit with all my UK friends- even with the people who don't like peanut butter!

made these for the church luncheon. they were ok, but thin. I would put them in a smaller pan to make them thicker and cut them into smaller squares.

Thanks so much for posting this recipe! My daycare used to give us these, and I found a recipe for it a few years ago, but it got lost (along with a whole lot of other recipes). Just lately I've been REALLY wanting these. I've never heard of these with the chocolate on top, but it is just as good!! Thanks so much!

Excellent! My kids, my husband and I, and my in-laws all LOVED this bar! I simplified it by mixing the chips in the batter, then baked it at 350 for 18 minutes. I totally skipped the frosting and no one missed it. My mother-in-law made sure she had this recipe when they left! I made this twice in one weekend - this is definitely a keeper!
