Pre-heat oven to 350 Fahrenheit and prepare 2 cookie sheets with parchment paper.
Over a bowl of a stand mixer using a paddle attachment, (or using a hand mixer and a large mixing bowl), cream the brown sugar, granulated sugar and unsalted butter in medium high speed, for around 2 minutes.
Add the peanut butter, egg, egg yolk and vanilla and mix until just combined.
Add the flour, baking soda and salt and mix until just combined. Do not over mix! you can mix the dry ingredients by hand for best results and to avoid over mixing.
Fold in the m&m’s carefully.
Using a large cookie scoop (3 Tablespoons), scoop the dough and place the cookie dough balls on your prepared cookie sheet, 2 inches apart from each other. Add a few extra chocolate m&m’s on top of the cookies, and bake for 8-10 minutes.
With the cookies right out of the oven, use a flat bottomed glass or measuring cup to flatten the cookies to 1/2″ thickness. Let cookies cool in the baking pan for 10 minutes, then transfer to a wire rack to cool completely.
If by any chance you haven’t eaten the whole batch and you have some leftover cookies, store them in an airtight container, away from any heat sources, for up to 5 days.
Store your cookie dough balls in the fridge for up to 5 days, and just pop them in the oven whenever you want one!
You can also freeze them for up to 3 months; bake them frozen, but add 1-2 more minutes to your baking time.
