Yield: 20 bars

Ingredients

  1. 1 ⅛ cups white sugar
  2. 1 ⅛ cups brown sugar
  3. 1 cup unsalted butter, softened
  4. 2 large eggs
  5. ¾ cup peanut butter
  6. 1 teaspoon vanilla extract
  7. 2 cups all-purpose flour
  8. 1 ⅔ cups rolled oats
  9. 1 teaspoon baking soda
  10. 1 pinch salt
  11. 2 cups powdered sugar
  12. 4 tablespoons unsalted butter, softened
  13. 2 tablespoons milk, or more as needed
  14. 2 tablespoons peanut butter
  15. 1 teaspoon vanilla extract

Instructions

  1. Preheat the oven to 350 degrees F (175 degrees C). Grease a 15×10-inch baking pan.
  2. 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.
  3. 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.
  4. 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.
  5. You can use margarine instead of butter.
  6. Refrigerating bars before frosting works best in my opinion.

GREAT!!

They don’t need a full layer of frosting. Make a simple icing (powdered sugar, vanilla, water or milk) and drizzle it on sparingly, rather than covered like a cake. That makes them more like the “peanut chews” (as they were called in the 70s) that we got from the cafeteria.

My kids like these bars.

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.
