Using an electric mixer, mix peanut butter, brown sugar, coconut oil, vanilla and eggs on high speed for 1 minute. Add oats, cinnamon, baking soda and salt and mix until combined. Stir in remaining ingredients with a rubber spatula.
Line a large baking sheet with parchment paper. Use a cookie scooper to scoop out even size balls. Press 2-3 m&m’s on the top of each cookie.
Bake 9-11 minutes until barely golden brown. Allow to cool for at least 5 minutes before transferring to a wire rack to finish cooling.
Enjoy immediately, store remaining cookies in an airtight container.
