My recipe for classic monster cookies that are chock full of creamy peanut butter, oats, chocolate chips, and M&M's makes both kids and adults reach for just one more cookie! Fast, EASY, soft, perfectly chewy, and they'll become a family FAVORITE in no time!

Beat together the sugars, butter, peanut butter, and vanilla. Add the eggs one at a time.


Add the oats, flour, baking soda, and salt, then beat. Add the M&M’s, toffee bits, chocolate chips, and coconut, then beat.


Form cookie dough balls and chill. Bake and let cool.
