1 cup M&Ms or candy-coated chocolate pieces ((200g))
½ cup semisweet chocolate chips ((75g))
Instructions:
Preheat the oven to 350°F. Line large baking sheets with parchment paper.
In a medium bowl, whisk or sift together the flour, salt, and baking soda. Stir in the oats and set aside.
In a large mixing bowl or the bowl of a stand mixer fitted with the paddle attachment, cream the butter and peanut butter together on medium speed, then scrape the bowl down and add both sugars. Beat on medium speed until light and fluffy, about 3 minutes.
Add the eggs one at a time, then add the vanilla. Scrape down the bowl and beat again until well mixed and fluffy, about 1 minute.
With the mixer on low, gradually add in the flour mixture, and beat until just combined. Stir in the M&Ms and chocolate chips.
Scoop the dough into 2 tablespoon-sized portions and roll into balls between the palms of your hands. Place about 2 inches apart on the baking sheets. (If desired, you can cover and chill the dough or dough balls for at least 20 minutes and up to 72 hours before baking.)
Bake for 10 to 12 minutes or until the cookies are golden around the edges, but still soft in the center. For crispy cookies, bake closer to 15 minutes
Let the cookies cool on the pans for a few minutes, then trransfer to a wire rack, and let cool completely.
