It's taken me a while to find this recipe. There are many versions of "the peanut butter bar" but, I believe this recipe comes the closest to what I remember eating in the 1960's (via our elementary school lunchroom). Boy those ladies could really cook back then!

  • Cream white sugar, brown sugar, butter, and eggs together in a mixing bowl. Mix in peanut butter and vanilla extract. Add flour and blend well. Add oats, baking soda, and salt and mix to combine. Spread into the prepared pan.

  • Bake in the preheated oven until golden and the edges start to pull away from the sides of the pan, about 20 minutes. Remove from the oven and let cool or chill in the refrigerator, about 30 minutes.

  • While bars cool, blend powdered sugar, butter, milk, and peanut butter together in a bowl, adding more milk to give frosting the desired consistency. Frost cooled bars and cut into 20 pieces.

Cook's Notes:

You can use margarine instead of butter.

Refrigerating bars before frosting works best in my opinion.

I opted to leave mine unfrosted - but these yield amazingly delicious chewy, peanut butter infused cookie bars! A touch crumbly, but mostly just perfectly thick and chewy!! Perfect for sharing at a potluck or packing on a picnic. Read More
