  • 4 oz (½) cup unsalted butter, softened
  • 106 grams (½ cup) brown sugar
  • 99 grams (½ cup) white sugar, plus more for topping
  • 135 grams (½ cup) peanut butter
  • 1 egg
  • 180 grams (1 ½ cups) flour
  • 1 tsp baking soda
  • ¼ tsp salt
  • 100 grams (½ cup) M&Ms, plus more for topping


  1. Preheat oven to 350º.
  2. In a stand mixer fitted with a paddle attachment, blend together the butter, sugars, and peanut butter on medium speed until combined. Scrape down the sides of the bowl.
  3. Add in the egg and mix until combined.
  4. With the mixer on low, add in the flour, baking soda, and salt and mix just until combined, scraping down the sides of the bowl as needed. Gently fold in most of the M&Ms, leaving a few aside to place directly on top of the cookies.
  5. Place the bowl of dough in the fridge to chill for at least 10 minutes.
  6. Using a 2 tablespoon scoop, form cookies into balls. Place remaining M&Ms on top of each cookie. Roll cookies in white sugar. Place each cookie on a parchment lined cookie sheet a few inches apart.
  7. Bake the cookies for about 12 minutes. You can use a round cookie cutter or cup to "cookie scoot" or round them out at about the 10 minute mark.
  8. Let the cookies cool for about 10 minutes on the baking sheet before carefully moving them to a cooling rack. Enjoy!


  • Leftover cookies can be stored in an airtight container for up to one week but are best when enjoyed within the first few days.
  • Cookie dough can be made ahead, scooped, and placed in a ziploc bag to be frozen for up to two months. Once you’re ready to bake, let the dough sit at room temperature for about 15 minutes and bake. You’ll need to add on an extra 5 minutes or so to the original baking time.
