  • 2 sticks unsalted butter (228 grams)
  • 1 cup light brown sugar (200 grams)
  • 1 cup minus 1 tablespoon granulated sugar 185 grams
  • 3/4 cup plus 1/2 tablespoon peanut butter Jif or Skippy (200 grams)
  • 2 large eggs 100 grams
  • 1 ½ tablespoons vanilla
  • 1 teaspoon salt
  • 1 teaspoon baking soda
  • 2 1/2 cups minus 1 teaspoon pastry flour Bob’s Red Mill (320 grams)
  • 10 ounces good quality dark 50 to 63% chocolate, cut into chunks**
  • 1/3 cup coarsely chopped peanuts
  • 2 packs of Reese’s Peanut Butter Cups 4 cups


  • In a large mixing bowl, beat the butter, peanut butter both sugars until light and creamy.
  • Add the eggs one at a time, beating for 30 seconds after each egg is added.
  • Beat in the vanilla, salt and baking soda. Add flour and stir until mixed, then stir in the chocolate chunks and peanuts.
  • Divide dough into 12 large chunks and arrange on foil lined plates. Chill for at least half an hour or until ready to bake.
  • When ready to bake, preheat oven to 350F.
  • Arrange the chunks on a parchment lined baking sheet, leaving plenty of room for spreading – about 6 to a sheet.
  • To bake, put one sheet of cookies on the center rack in the350 degree oven. Close the door, set the timer for 18 minutes and reduce the heat to 325 degrees F. Bake for about 18 minutes (but check at 15) at 325 until the cookies appear set.
  • While the cookies bake, cut each Reese’s cup into 6 wedges.
  • When cookies are done, remove from oven and set some of the Reese’s wedges on top of hot cookies.
  • Let them cool on the baking sheet for about 10 minutes, then let cool completely or transfer to the freezer to quick cool.


For the pastry flour, I used Bob's Red Mill which comes in a big pink bag. You could swap out the pastry flour for an even mix (160 grams each) of bread flour and cake flour or possibly use King Arthur AP. I really am enjoying the Bob's flour. For the chocolate, I like Lindt Sweet Dark which melts quite nicely. It doesn't set up very quickly, so I like to set the chunks by throwing the cookies in the freezer. Then again, I'm a weirdo who doesn't like these gooey or melt-y.
