Step 1

Preheat the oven to 350 degrees Line two large baking sheets with Silpat baking mats or parchment paper. Set aside.

Step 2

In a medium bowl, stir together the oats, flour, baking soda, and salt. Set aside.

Step 3

Using a stand mixer or hand-held mixer, beat the butter, peanut butter, and sugars together until creamy and smooth, on medium speed. Scrape down the sides of the bowl with a spatula, if necessary. Beat in the egg and vanilla extract. Mix until well combined.

Step 4

Add in the dry ingredients and mix on low until just until the combined. Don't over mix. Gently stir in the chocolate chips and M&M’s.

Step 5

Scoop the cookies into round balls, about 2 tablespoons of dough per cookie, and place on the prepared baking sheets, leaving 2 inches in between cookies. Bake for 10-12 minutes, or until the cookies are lightly browned around the edges, but still soft in the middle.

Step 6

Remove cookies from oven and sprinkle the cookies with sea salt. You can also gently press additional chocolate chips and M&M’s on top of the cookies to make them look extra pretty. Let the cookies cool on the baking sheet for about 5 minutes or until set. When set, transfer cookies to a wire rack and cool completely.
