  • 1 cup graham flour
  • 3/4 teaspoon baking soda
  • 1/2 teaspoon salt
  • 3/4 cup (1 1/2 sticks) unsalted butter, softened
  • 3/4 cup Smooth Operator peanut butter
  • 1 cup demerara sugar
  • 1 large egg
  • 1 cup chopped milk chocolate
  • 1 cup roasted salted peanuts (blanched splits)


  1. Preheat the oven to 350°F. Line two baking sheets with parchment paper.

  2. In a large bowl, sift together the flour, baking soda, and salt set aside.

  3. In a separate large bowl, use an electric mixer to cream together the butter, peanut butter, and sugar. Add the egg and continue mixing. Add the dry ingredients, 1/2 cup at a time, mixing until the dough is firm. If the dough is too dry, add water by the tablespoon (but no more than 1/4 cup) until it is moist and easier to work with. Fold in the chocolate and the peanuts.

  4. Refrigerate the dough for 1 hour. When chilled, use a scoop, spoon, or your hands to form 1 inch wide balls of dough. Arrange on a cookie sheet at least 1 inch apart. Flatten each ball with your palm or the back of a spoon. Bake for 12 minutes or until golden. Allow to cool completely before removing from baking sheet. Store in an airtight container for up to 2 weeks.
