Ingredients
 
 

Peanut Butter Oatmeal Squares

  • 4 cups old fashioned oatmeal
  • cup melted butter
  • 1 cup brown sugar
  • ½ cup crunchy peanut butter
  • ¼ cup dark Karo syrup

Frosting

  • 10 oz. package semi-sweet chocolate chips
  • 11 oz. package butterscotch chips
  • ¾ cup creamy peanut butter

Instructions
 

  • Preheat oven to 400 degrees
  • In a large bowl, thoroughly mix the first five ingredients together.
  • Press into a 10 x 14 baking pan lined with non-stick foil.
  • Bake in oven for 6-10 minutes, until they begin to turn lightly golden and bubble slightly. Remove and let cool.
  • Combine the 3 frosting ingredients in a nonstick saucepan and melt over low heat, stirring constantly.
  • Pour over peanut butter oatmeal squares and spread over top.
  • Chill in refrigerator for 20 minutes. Remove and cut into squares or bars. Return to refrigerator and continue chilling for at least 2 hours before serving. Store covered in refrigerator and serve cold.

Notes

You can use a different size pan for the recipe. If you use a large (11 x 17) cookie sheet, your baking time will be approximately 6-8 minutes. If you use a smaller pan (9 x 13), your baking time will increase to approximately 12-15 minutes or maybe a little more. The smaller the pan, the longer the baking time will be because the bars will be thicker. Keep an eye on them so they don't over bake.
If you prefer just a chocolate-peanut butter frosting without the butterscotch, use 20 oz. of chocolate chips and 1 cup of creamy peanut butter.
