Sweet and gooey oatmeal cookie bars with the favorite flavor combo - peanut butter and jam.
  • For cookie crust:
  • ¾ cup butter, softened
  • ½ cup peanut butter
  • 1 cup brown sugar, packed
  • 1 large egg
  • 1 tsp. vanilla
  • 2 cups all-purpose flour (can use half whole wheat)
  • 1½ cups old-fashioned rolled oats
  • 1 tsp. baking soda
  • ¼ tsp. salt
  • 10-12 oz. your favorite jam or jelly, whisked until smooth
  • For crumb topping:
  • ½ cup all-purpose flour
  • ½ cup brown sugar, packed
  • ½ cup old-fashioned rolled oats
  • ¼ tsp. salt
  • ½ cup chopped peanuts
  • ½ cup butter, cold, cut into tablespoons
  1. For cookie crust: Cream butter and peanut butter until light and fluffy. Add the brown sugar and beat until well-combined. Add the egg and beat for another minute or two, until light, fluffy, and very creamy. Add the vanilla and mix again. Whisk the flour, baking soda, and salt together. Add the flour to the creamed mixture in two additions. Add the rolled oats and mix until crumbly.
  2. Press into the bottom and halfway up the sides of a buttered, 9×13″ glass baking dish. Bake at 350 degrees for 15 minutes. Remove from oven and spread jam over the crust, being careful not to press at all into the crust. (It will still be gooey.) Prepare the crumb topping.
  3. For the crumb topping: Mix the flour, brown sugar, oats, and salt together. Add the cold butter and use your fingers or a pastry cutter to mix it until crumbly. Add the peanuts and gently mix to combine. Sprinkle over the jam. Bake for an additional 25-30 minutes, or until the bottom is nicely browned, the top is lightly golden, and the jam filing is bubbling all over.
  4. Let cool completely before cutting into bars.
