Thick and chewy Monster Cookies made with oats, peanut butter, M&M candies and chocolate chips. These are always a huge hit with family and friends.
Preheat oven to 350 degrees F.
Cream the butter and sugar together really well—at least 2-3 minutes until light and fluffy.
Add peanut butter and mix well. Add egg and vanilla and mix.
In a separate mixing bowl stir together the flour, oats, salt, baking powder and baking soda. (Be extra careful not to add too much flour).
Add to the wet mixture and mix to combine. Stir in chocolate chips and M&M’s.
Bake at 350 degrees for 10-12 minutes, or a little longer if you make them bigger than a 1 inch cookie scoop. Don't over bake--they will look just set.
Remove them from the oven and allow them to cool completely on the pan.
