The Real Cafeteria Peanut Butter Bars

READY IN: 55mins
Recipe by LinsietheGreat

These are exactly like the ones I grew up with in the 80's! You can half the recipe and use a 9x13; I like to make a bunch and either freeze them or gobble them. (I have five kids...they usually get gobbled! ;) Sometimes I leave off the chocolate chip layer, put the PB frosting directly on top of the bars, and smother with Texas sheet cake icing instead. YUM!

I've had these bars tagged for so long and finally took the time to whip them up today for DH's lunchbox treats. I halved the recipe and used a 9x13 pan, so the bars were a little thinner than were supposed to be, but that's okay because these are super peanut-buttery! DH thinks these are just like the public school peanut butter bars and for as easy as they were to make, I'm sure I'll be making these many more times in the future- try these bars!! Edit: I did not try to pb icing as we didn't remember ours having it in the past. Thanks!
