  • 10 tablespoons unsalted butter softened
  • 1/2 cup light brown sugar
  • 1/4 cup granulated sugar
  • 1 large egg
  • 1 teaspoon pure vanilla extract
  • 1 1/2 cups all purpose flour
  • 1 1/2 teaspoons cornstarch
  • 1/4 teaspoon baking soda
  • 1/8 teaspoon salt
  • 1 cup M&M's divided


  • 4 tablespoons unsalted butter softened
  • 1 1/4 cups powdered sugar sifted
  • 1/2 teaspoon pure vanilla extract
  • 1-2 tablespoons milk, half and half or cream
  • Food coloring optional (I used 1 drop of red food coloring)


  • Preheat oven to 350°F. Line a 9 1/2 inch pie dish with a round of parchment paper and grease the dish. Set aside.
  • With a hand mixer or stand mixer, beat butter and sugars on medium speed for about one minute, until smooth and creamy. Add egg and vanilla extract, and beat to combine, scraping the sides of the bowl as necessary.
  • In a separate bowl, combine flour, cornstarch, baking soda, and salt. With the mixer on low, slowly add the flour mixture to the wet ingredients, beating until combined. By hand, stir in 3/4 cup of M&M's.
  • Evenly press the dough into the prepared pie dish. The dough will be thick and sticky.Wet your fingertips with a little water (if necessary) to help flatten the dough into the dish. Lightly press the remaining 1/4 cup M&M's over the top.
  • Bake for 23-25 minutes, until light golden brown. Cool completely.


  • With a stand mixer or hand mixer, beat butter and sugar on medium speed until smooth and creamy. Add vanilla extract and 1 tablespoon milk. Beat for an additional minute. Add more milk, if needed, to thin out the frosting. Beat in food coloring, if desired
  • Use a decorating tip (I used a star tip) to frost the outer edge of the cookie. Decorate with additional M&M's, if desired.
