Peanut Butter Oatmeal Squares Recipe

The combination of peanut butter and oatmeal makes these bars popular. My children love them with a cold glass of milk, and I've taken them to many church suppers, too.
TOTAL TIME: Prep: 10 min. + bake: 20 min. + cooling YIELD:24 servings


  • 1 cup shortening
  • 1 cup sugar
  • 1 cup packed brown sugar
  • 2/3 cup peanut butter
  • 2 eggs
  • 1/3 cup water
  • 1 teaspoon vanilla extract
  • 2 cups all-purpose flour
  • 1-1/2 cups quick-cooking oats

  • ICING:
  • 1/3 cup butter, softened
  • 2/3 cup peanut butter
  • 2 cups confectioners' sugar
  • 1/3 cup 2% milk


  • 1. In a large bowl, cream the shortening, sugars and peanut butter until light and fluffy. Add eggs, one at a time, beating well after each addition. Beat in water and vanilla.

"These PB bars will go quick! Usually make half a recipe using a 11x7 glass pan. easy to assemble. Love the fact that topping goes on warm, no need to wait to frost! But wait until completely cool to cut. Perfect for snow shoveling kids to enjoy! As a volunteer feild editor for Taste of Home magazine I love using a variety of recipes that use classic ingredients."
