Stuffed with chunks of Reese's peanut butter cups, these homemade peanut butter cup cookies are a twist on classic chocolate chip cookies. For best results, chill the cookie dough balls for an hour in the fridge before popping the cookies into the oven.


  • 225g Unsalted butter, at room temperature
  • 170g Dark Brown or Muscovado Sugar
  • 100g Granulated / White Sugar
  • 50g Raw / Turbinado Sugar
  • 1 egg
  • 1 tsp vanilla bean paste or vanilla extract
  • 300g All-purpose flour
  • 1/2 tsp baking soda
  • 1/2 tsp baking powder
  • 1 tsp salt
  • 250g chopped peanut butter cups, plus a few extra for on the top
  • 100g milk chocolate, coarsely chopped, plus more for finishing
  • 100g dark chocolate, coarsely chopped, plus more for finishing
  • Flaky Sea Salt such as Maldon for finishing


  1. In the bowl of a stand mixer fitted with the paddle attachment, or with an electric mixer, cream together the butter and sugars on high speed for 5 minutes, until pale, and light and fluffy. Add the egg and vanilla, and mix to combine, scraping down the bowl when necessary.
  2. Sift together the flour, baking soda, baking powder, and salt. Add to the mixing bowl, and mix on low to just combine (you still want a few streaks of flour remaining that will get mixed in when you add the chocolate).
  3. Add the chopped peanut butter cups and chopped chocolate and mix until just incorporated. Remove the bowl from the mixer and give a few mixes by hand using a flexible spatula, to ensure even incorporation of the chocolate.
  4. Using a 2 Tbsp Cookie scoop, scoop out balls of dough onto a baking sheet lined with parchment paper (you can place them close together). If you want big puddles on the top of your cookies, you flatten a ball of dough, press the chocolate and chopped peanut butter cups onto the top side, then continue as usual and roll it into a ball, which then gives you even chocolate distribution as the cookie bakes.
  5. If you are not adding additional chocolate, there is no need to re-shape into a ball - you can bake right from the scooped shape. Cover the sheet pan with plastic wrap and chill the dough balls for an hour in the fridge (if you want to freeze some, now is the time, see notes in the post)
  6. Toward the end of the chilling process, preheat the oven to 350°f / 180°c. Line 2-3 baking sheets with parchment paper (you can bake these in batches)
  7. Arrange 6 cookie dough balls on a baking sheet, leaving room for spreading. Leave the remainder of the dough balls in the fridge.
  8. Bake for 13-14 minutes, or until lightly golden and beginning to set. Baking time depends on personal preference - if you like them quite soft, bake for 13 mins, if you like them a tiny bit crispy then bake for 14. Remove from the oven, and if desired, use a round cookie cutter slightly larger than the cookie to scoot them into a perfectly round shape. Add a few more chunks of chopped peanut butter cups if you see any big bare spots.
  9. Sprinkle liberally with flaky sea salt. Allow to cool on the pan - the cookies will deflate slightly as they cool. Repeat the baking process with the remaining cookies.
  10. Store leftovers in an airtight container.
