PB & J Gooey Bars with Peanut Butter Streusel

PB & J Gooey Bars with Peanut Butter Streusel

  • Author: Molly
  • Total Time: 50 minutes
  • Yield: 16 servings 1x



For the Bars:

  • ¾ cup all-purpose flour
  • 1 cup old-fashioned oats
  • ½ teaspoon baking soda
  • ¼ teaspoon baking powder
  • 1 teaspoon fine salt
  • 1 stick unsalted butter, at room temperature
  • ½ cup creamy peanut butter
  • ¼ cup sugar
  • ¾ cup packed light brown sugar
  • 1 large egg
  • 1 teaspoon vanilla extract
  • ⅔ cup jam or jelly (I like strawberry)

For the Streusel Topping:

  • ¼ cup all-purpose flour
  • ¼ cup packed light brown sugar
  • 1 tablespoon unsalted butter
  • 2 tablespoons creamy peanut butter
  • ¼ cup coarsely chopped peanuts
  • ¼ cup mini chocolate chips
  • Pinch of salt


For the Bars:

  1. Preheat oven to 350°F. Butter the bottom and sides of an 8 x 8-inch baking pan. Line the pan with parchment paper, letting the parchment extend up two sides of the pan and overhang slightly on both ends. Spray the parchment paper with nonstick cooking spray.
  2. In a medium bowl, whisk together the flour, oats, baking soda, baking powder, and salt. Set aside.
  3. In the bowl of a stand mixer fitted with the paddle attachment (or using a hand mixer), cream together the butter and peanut butter until light and fluffy. Add in the sugars and beat again until light and fluffy. Scrape down the sides of the bowl and then add in the egg and vanilla extract. Beat until smooth.
  4. Slowly mix in the dry ingredients until just incorporated. Scrape down the sides of the bowl to make sure all ingredients are well mixed. Spread the dough in the prepared pan and smooth out the top. Bake the base for 15 minutes or until it is golden around the edges and starting to set.
  5. Carefully spread the jam/jelly over the base in an even layer. Top with the streusel topping (recipe below) and bake for another 20-25 minutes, or until golden and set throughout. Allow to cool completely in the pan and then remove using the parchment overhang to help lift the bars out of the pan. Slice and serve with ice cold milk!

For the Streusel Topping:

  1. Combine the flour and sugar in a small bowl.
  2. Using a pastry cutter or a fork, mix in the butter and peanut butter until the mixture is crumbly. Stir in the peanuts, chocolate chips, and salt.
  3. Sprinkle evenly over the top of the bars before baking.
