These Peanut Butter and Jelly Oat Bars have a soft peanut butter cookie base, mixed berry preserves, and more crumbled peanut butter cookie dough!


  • 1/2 cup butter, softened
  • 2 tablespoons dark brown sugar, packed
  • 1/4 cup granulated sugar
  • 1 egg
  • 1/3 cup crunchy peanut butter
  • 1/2 teaspoon vanilla extract
  • 3/4 cup old fashioned oats
  • 1 1/4 cups white whole wheat flour
  • 1/2 teaspoon baking soda
  • 1/2 teaspoon salt
  • 1/2 cup (heaping) berry preserves or spread
  • 2 tablespoons powdered sugar, for dusting on top


  1. Preheat the oven to 375 degrees.
  2. Prepare an 8 by 8 inch baking pan by spraying with nonstick spray, and lining with parchment paper.
  3. In a large bowl, cream butter and sugars together with the paddle attachment on medium high speed. Add egg and mix, then peanut butter and vanilla extract.
  4. In a separate bowl, mix oats, flour, baking soda and salt.
  5. Add the dry ingredients to the peanut butter mixture and stir until a dough forms.
  6. Use 2/3 of the dough for the bottom layer of the bars, patting it firmly into an even layer in the bottom of the pan.
  7. Spread the fruit preserves over the top of the dough.
  8. Sprinkle the remaining dough crumbles over the top.
  9. Bake at 375 degrees for 22-24 minutes. Allow the pan to cool completely, then lift uncut bars out using the parchment paper handles. Dust with powdered sugar. Cut into bars.
