Ingredients

Cookie Dough

  • 1/2 cup butter softened
  • 1 1/2 cups brown sugar
  • 3/4 cup creamy peanut butter
  • 1 egg
  • 1/4 cup milk
  • 2 teaspoons vanilla
  • 1/2 teaspoon salt
  • 3/4 teaspoon baking soda
  • 2 cups all-purpose flour
  • 1/2 cup mini chocolate chips

Ganache

  • 1 (12 oz) bag semisweet chocolate chips
  • 4 Tbsp. butter
  • 2 Tbsp. honey
  • 2 Tbsp. milk

Instructions

  • Preheat the oven to 375 degrees.
  • Prepare a 9″x13″ baking dish with parchment paper.
  • Note: You’ll want to leave an inch or two of parchment paper over the edge on each end so that you can lift the bars out of the pan later on.
  • Cream the butter and brown sugar together. Beat in peanut butter, eggs, vanilla, and milk.
  • Add flour, baking soda, and salt.
  • Stir in chocolate chips.
  • Press cookie dough into the prepared baking dish.
  • Bake for 22-24 minutes. Cookie bars will be soft. Allow bars to cool for 30 minutes.
  • Combine ganache ingredients and melt on the stovetop over low (med/low) heat OR in the microwave in 15-20 second intervals, stirring in between each interval until melted and smooth.
  • Spread ganache over cookie bars.
  • Let cookie bars stand another 30 minutes then chill in the refrigerator for 1 hour. DO NOT skip that part if you want fudgy cookie bars. 
    Lift the cookie bars from the pan using the parchment paper and slice them into 24-48 bars.
