Beat in the baking soda, then beat in the salt ONLY if you used unsalted butter.
Add oats one cup at a time, mixing well. Stir in the chocolate chips and M&Ms mixing until completely incorporated.
Using a heaping ⅓ cup measure or a more level ½ cup, scoop out large chunks of dough. Each should weigh around 4 ½ oz. Shape into firm balls and press tops to make mounds.
Arrange about 5 to a baking sheet and bake one sheet at a time for 15 minutes. Scoop onto baking sheet using a serving spoon or small ice cream scoop. Bake at 350 degrees for 15 minutes. Enjoy!
