Equipment

Stand Mixer

Ingredients

1 cup all-purpose flour
1 1/4 cups old-fashioned rolled oats (not quick cooking)
1 cup brown sugar
8 Tbsp (1 stick) butter room temperature
1 large egg + 1 egg yolk
1/2 tsp baking soda
1/4 teaspoon salt
1 1/2 teaspoon vanilla extract
1/2 cup chocolate chips
1/2 cup M&Ms

Instructions

Preheat the oven to 350 degrees Fahrenheit (177 degrees Celsius). Line two baking sheets with parchment paper or a Silpat mat, and set aside.
In the bowl of a stand mixer, beat together the butter, brown sugar, and vanilla for 3–4 minutes on medium-high. Add the egg and mix, then add the egg yolk, mixing just until combined.
In a medium-sized mixing bowl, combine the flour, oats, baking soda, and salt. Whisk to combine. With the mixing speed on low, gradually add the dry ingredients, mixing until no flour pockets remain. Remove the bowl from the stand and fold in the chocolate chips and M&Ms. Allow the dough to chill in the refrigerator for 1 hour before baking.
Scoop the chilled dough onto the prepared baking sheets. Gently pat down each ball. Place the cookie dough balls in the oven and bake for 10–12 minutes, or until the edges of the cookies begin to turn golden brown in color. The centers should look slightly underbaked; they will firm up once cooled. Remove from the oven and allow the cookies to cool on the sheets for 3–4 minutes before transferring to a wire cooling rack to cool completely.

Notes

To STORE these M&M Oatmeal Chocolate Chip Cookies, let them cool completely before placing them in an airtight container at room temperature. They’ll stay fresh and soft for about 3–4 days.

For longer storage, place cooled cookies in a freezer-safe bag or container and FREEZE for up to 2 months. To REHEAT, thaw them at room temperature or warm them in the microwave for about 10 seconds to soften them slightly and bring out the chocolate flavor again.
