A Sweet Return to Childhood: School Lunch Peanut Butter Bars

These peanut butter bars are more than just a treat; they’re a nostalgic nod to those carefree school days. Follow these simple steps and tips to ensure your bars are just as you remember perhaps even a bit better!

Tips for Perfect Peanut Butter Bars:

  1. Smooth Batter: Ensure the butter and peanut butter are well incorporated into the sugar and eggs for a smooth, uniform batter.
  2. Even Spreading: Press the oat mixture evenly into the pan to avoid uneven baking and to ensure every bar cooks perfectly.
  3. Cool Completely: Allow the bars to cool fully before frosting to prevent the frosting from melting into the warm bars.
  4. Creamy Frosting: Beat the frosting ingredients until creamy and smooth for easy spreading.
  5. Slicing: Use a sharp knife to cut the bars, cleaning the blade between slices for neat, clean cuts.
