  • Total Time: 40 to 45 minutes
  • Yield: 24 bars 1x

Ingredients

Scale

Dry Ingredients

  • 2 ½ cups All-Purpose Flour
  • 1 teaspoon Baking Soda
  • ½ teaspoon Salt

Wet Ingredients

  • 1 cup Unsalted Butter, softened
  • 1 cup Brown Sugar, packed
  • ½ cup Granulated Sugar
  • 2 large Eggs
  • 1 teaspoon Vanilla Extract
  • ½ cup Peanut Butter (smooth)

Add-ins

  • 1 cup Reese’s Pieces
  • 1 cup Chocolate Chips

Instructions

  1. Prepare Your Baking Pan: Preheat your oven to 350°F (175°C) and line a 9×13-inch baking pan with parchment paper or lightly grease it to prevent sticking.
  2. Mix Dry Ingredients: In a medium bowl, whisk together all-purpose flour, baking soda, and salt to build structure and leavening for the bars.
  3. Cream Butter and Sugars: In a large bowl, beat softened butter with brown sugar and granulated sugar until light and fluffy, adding creaminess and tenderness.
  4. Add Eggs, Vanilla, and Peanut Butter: Beat in eggs one at a time, followed by vanilla extract and smooth peanut butter, mixing well for even flavor distribution.
  5. Combine Dry and Wet Ingredients: Slowly add the dry mixture to the wet ingredients and stir until just combined to avoid tough bars.
  6. Fold in Reese’s Pieces and Chocolate Chips: Gently fold in the Reese’s Pieces candy and chocolate chips, ensuring even distribution throughout the batter.
  7. Bake Until Golden: Spread the batter evenly in the prepared pan and bake for 25 to 30 minutes until edges are lightly golden and a toothpick inserted in the center comes out mostly clean with a few moist crumbs.
  8. Cool and Slice: Let the cookie bars cool completely in the pan before slicing into squares to help them firm up and maintain gooeyness.

Notes

  • Softened Butter Is Key: Use softened (not melted) butter for the perfect texture.
  • Don’t Overmix: Stir batter just until combined to keep bars soft and tender.
  • Use Fresh Reese’s Pieces: Fresher candies retain crunch and color better after baking.
  • Check Oven Temperature: Use an oven thermometer to ensure even baking and avoid dryness.
  • Cool Fully Before Cutting: Prevents crumbling and ensures neat, gooey squares.
