How to Make Chunky Chocolate Peanut Butter Bars

  1. Preheat oven to 325°F (160°C). Place rack in the center of the oven.
  2. Grease and flour a 13x9 inch baking pan.
  3. In a large bowl, combine 1 box (15.25 oz) chocolate cake mix, 1 cup creamy peanut butter, 1/2 cup (1 stick) melted unsalted butter, and 2 large eggs.
  4. Beat with an electric mixer on low speed for 1 minute, then scrape down the sides of the bowl.
  5. The mixture will be thick. Reserve 1 1/2 cups of the mixture for the topping.
  6. Press the remaining crust mixture evenly into the prepared pan.
  7. In a medium saucepan over low heat, combine 12 oz semi-sweet chocolate chips, 1 (14 oz) can sweetened condensed milk, and 2 tablespoons unsalted butter.
  8. Stir constantly until the chocolate is melted and the mixture is smooth and well combined (3-4 minutes).
  9. Remove from heat and stir in 1 teaspoon vanilla extract.
  10. Pour the chocolate mixture evenly over the crust.
  11. Crumble the reserved crust mixture over the chocolate layer.
  12. Bake for 25-30 minutes, or until the edges are lightly browned.
  13. Let cool completely on a wire rack for at least 30 minutes before cutting.
  14. Cut into 48 bars.
  15. Store in an airtight container at room temperature for up to 3 days, or in the refrigerator for up to 1 week. Freezes beautifully!
