  • 1 cup + 1/4 cup creamy peanut butter (not the natural drippy kind. Jif or Skippy works best)
  • 2/3 cup light brown sugar, loosely packed
  • 2 teaspoons vanilla extract
  • 1 large egg
  • 1/3 cup unsweetened natural cocoa powder
  • 1 teaspoon baking soda
  • 1/2 teaspoon salt
  • 1/2 cup dark chocolate chips, plus extra for topping


  1. Preheat oven to 350℉.

  2. Line a plate with wax paper and spoon 12 teaspoon sized blobs (1/4 cup total) of peanut butter on the plate. Freeze while you prepare the batter (should only take 15-20 minutes). (You will be using these to stuff the cookies with so they need to be hardened).

  3. In a medium mixing bowl, combine all ingredients except for chocolate chips. Mix until thoroughly combined. Add the chocolate chips and mix until incorporated. Roll cookies into 12 equal balls.

  4. Remove the peanut butter blobs from the freezer. Break the cookie balls in half and put a peanut butter blob inside each. Add the cookie halves back together and seal with your fingers to ensure that no peanut butter comes out. Press a few extra chocolate chips in the tops of the cookies, if desired. Place cookie dough balls on a baking sheet, spaced 2 inches apart. 

  5. Bake cookies for 12-14 minutes or until set. Let cool for at least 20 minutes. These cookies are very fragile when hot! Enjoy!
