Instructions

  1. Preheat your oven to 350°F (175°C). Grease a 9×13 inch baking pan and set aside.
  2. In a large bowl, cream together the softened butter, granulated sugar, and brown sugar until light and fluffy.
  3. Add the eggs and vanilla extract, mixing well until fully combined.
  4. In another bowl, whisk together the flour, baking soda, and salt.
  5. Gradually add the dry ingredients to the wet mixture, stirring just until combined.
  6. Fold in the chocolate chips and half of the peanut butter (1/2 cup).
  7. Spread the batter evenly into the prepared baking pan.
  8. Gently heat the remaining 1/2 cup of peanut butter in the microwave for about 20-30 seconds until it’s smooth and melted.
  9. Drizzle the melted peanut butter over the batter in the pan, using a knife to swirl it into beautiful marbled patterns.
  10. Sprinkle chopped peanuts on top if desired.
  11. Bake for 25 minutes, or until the edges are golden and a toothpick inserted into the center comes out clean.
  12. Allow the bars to cool completely in the pan before cutting into squares.

Helpful Tips

  • For a more intense peanut flavor, use chunky peanut butter and increase the amount of chopped peanuts.
  • If you’re short on time, line the baking pan with parchment paper for easier removal and cleanup.
  • Replace semi-sweet chocolate chips with milk chocolate or dark chocolate for a twist on the flavor.

Storage Instructions

Store the cookie bars in an airtight container at room temperature for up to one week. For longer storage, place them in the refrigerator for up to two weeks or freeze for up to three months, ensuring they are well-wrapped to maintain freshness.
