these thick and chewy m&m chocolate chip cookies need just 10 ingredients and 15 minutes in the oven for a fun cookie everyone is sure to love!


  • 1 stick (1/2 cup) unsalted butter, slightly melted or just room temperature (*see note)
  • 3/4 cup light brown sugar
  • 1/4 cup white sugar
  • 1 large egg
  • 1 teaspoon pure vanilla extract
  • 2 cups all purpose flour
  • 1/4 teaspoon salt
  • 1/2 teaspoon baking powder
  • 1/3 cup mini chocolate chips
  • 1/3 cup mini m&ms


  1. In a stand mixer or medium mixing bowl, add slightly melted or room temperature butter and sugars.  Cream together with stand mixer paddle or an electric hand mixer for 2 minutes until pale and creamy.
  2. Add egg and vanilla and beat for another minute.
  3. Add flour, salt and baking powder and beat until just combined.
  4. Gently fold in chocolate chips and m&ms.
  5. Chill in the fridge for at least 30 minutes.
  6. Just before ready to bake, preheat oven to 375 degrees F and line a baking sheet with parchment paper or a silpat.
  7. Scoop out about 2 tablespoons of dough (note that you can make these as big or as little as you’d like) and roll into a loose ball.  Place each ball about 2 inches apart on baking sheet (though they won’t spread very much).
  8. Bake for 12-15 minutes or until bottoms and tops are lightly browned (you may need slightly longer for larger sized cookies).
  9. Allow to cool for 2 minutes on the baking sheet before transferring to a wire rack to finish cooling.


  • The butter shouldn’t be total liquid, just soft enough to cream with the sugars
