Soft Baked M&M Cookies

These rainbow M&M cookies are soft-baked style with extra chewy edges. We recommend mini M&Ms so you can pack more into each cookie. Chilling the cookie dough for 2 hours is an imperative step, so make sure you set aside enough time.

Ingredients

  • 2 cups + 2 Tablespoons (265g) all-purpose flour (spooned & leveled)
  • 1 teaspoon cornstarch
  • 1 teaspoon baking soda
  • 1/2 teaspoon salt
  • 3/4 cup (12 Tbsp; 170g) unsalted butter, softened to room temperature
  • 3/4 cup (150g) packed light or dark brown sugar
  • 1/2 cup (100g) granulated sugar
  • 1 large egg + 1 egg yolk, at room temperature
  • 1 and 1/2 teaspoons pure vanilla extract
  • 1 cup mini M&Ms (plus 2 Tablespoons for topping, optional)

Directions

  • Whisk the flour, cornstarch, baking soda, and salt together in a medium bowl. Set aside.
  • In large bowl using a hand-held mixer or stand mixer fitted with a paddle attachment, beat softened butter for about 1 minute on medium speed until creamy. Add the brown sugar and granulated sugar, then beat on medium-high speed until creamy and combined. Scrape down the sides and bottom of the bowl as needed. Beat in egg, egg yolk, and vanilla extract. Scrape down the sides and bottom of the bowl as needed. With the mixer running on low speed, slowly add dry ingredients to wet ingredients. Pour in 1 cup M&Ms and beat on low speed for 20 seconds or until combined. Once completely combined, cover cookie dough tightly and chill in the refrigerator for 2 hours or up to 5 days.
  • Preheat oven to 350°F (177°C). Line baking sheets with parchment paper or silicone baking mats. Set aside.
  • Roll cookie dough into balls, about 1.5 Tablespoons of dough per cookie, and arrange 3 inches apart on the baking sheets. I like to use a medium cookie scoop here. Bake for 11-12 minutes or until lightly browned on the sides. The centers will look soft.
  • Remove from the oven and allow cookies to cool on the baking sheet for 5 minutes. While the cookies are still warm, press the remaining 2 Tablespoons of M&Ms into the tops of the cookies. This is optional and just for looks. Transfer to a wire rack to cool completely.
  • Cookies stay fresh covered at room temperature for up to 1 week.
