Servings: 60 small cookies


  • 1 cup unsalted butter softened
  • 1/2 cup sugar
  • 1 cup light brown sugar
  • 1 large egg
  • 2 large egg yolks
  • 2 teaspoons vanilla extract
  • 2 1/4 cups all purpose flour
  • 2 teaspoons corn starch
  • 1 teaspoon baking soda
  • 1/2 teaspoon salt
  • 3/4 cup crushed Oreos
  • 3/4 cup mini M&Ms plus more for tops if desired


  • Preheat oven to 350 degrees. Line cookie sheets with parchment paper or silicone baking mats.
  • In a large bowl, use electric mixer on medium-high speed to beat butter, sugar, and brown sugar together until lightened, about 3 minutes.
  • On low speed, beat in egg and egg yolks one at a time, scraping sides as needed. Then, beat in vanilla extract.
  • In a small bowl, stir together flour, cornstarch, baking soda, and salt. On medium speed, beat in flour mixture 1/2 cup at at time, until well combined. Stir in oreos and M&Ms.
  • Scoop dough in 1/2 tbsp sized balls on prepared sheets, about 2 inches apart. If you want the tops of the cookies to have visible M&Ms, press a few mini M&Ms on the top of each dough ball. Bake for 8-9 minutes, or until tops are golden.
  • Let cool on sheet for a few minutes before removing to cooling rack.
