Oatmeal Monster Cookies with M&M’s are perfectly soft & chewy and so easy to make. The best way to serve them is with a tall glass of milk.
They are packed with yummy oats, white chocolate chips and chocolate candy M & M’s.
They are super thick, chewy and full of flavor. I slightly under-bake them to get the perfectly soft and chewy center that my cookie loving heart just can’t resist.
These cookies come together easily without having to use your mixer. The best way to serve them would be alongside a nice tall glass of cold milk.
