Ingredients

  • 2 12 cups milk chocolate chips
  • 4 tablespoons unsalted butter, at room temperature
  • 14 cup flour, plus 2 tablespoons
  • 1 teaspoon baking powder
  • 12 teaspoon salt
  • 2 eggs, at room temperature
  • 12 cup granulated sugar
  • 1 teaspoon pure vanilla extract
  • 12 cup creamy peanut butter
  • 3 tablespoons confectioners' sugar

Method

  • Preheat the oven to 350.
  • Line 2 cookie sheets with parchment paper.
  • In a medium, microwavable bowl, melt together 2 cups chocolate chips and 2 tablespoons butter on medium power until almost melted, about 1 1/2 minutes; stir just until smooth.
  • In a small bowl, whisk together the flour, baking powder and 1/4 teaspoon salt.
  • Using an electric mixer, beat together the eggs, granulated sugar and vanilla at high speed until thickened and fluffy, about 5 minutes.
  • Mix in the melted chocolate at medium speed; whisk in the flour mixture.
  • Stir in the remaining 1/2 cup chocolate chips.
  • Refrigerate the dough until firm enough to scoop, but still soft, 10 to 15 minutes.
  • Onto each prepared pan, drop 12 rounded tablespoons of dough 2 inches apart.
  • Bake, switching and rotating the pans halfway through baking, until the cookies appear bubbly and still soft, about 15 minutes.
  • Let cool completely.
  • In a medium bowl, beat together the remaining 2 tablespoons butter and the peanut butter.
  • Sift in the confectioners sugar and the remaining 1/4 teaspoon salt; beat until fluffy.
  • On the flat side of each of 8 cookies, spread about 1 1/2 tablespoons of the peanut butter mixture; sandwich with the remaining cookies.
