Gather the ingredients - * Peanut butter * Brown sugar * Vanilla extract * Butter * Flour * Oats * Milk * M&Ms * Chocolate chips
Spread the flour and oats on the baking sheet and then bake them for 8-10 minutes or until the flour is lightly browned around the edges.
Add the butter, peanut butter, and brown sugar to the bowl of a stand mixer fitted with the paddle attachment. Beat on medium speed until light and fluffy - at least 2 minutes.
Next, add the vanilla and mix to combine. With the mixer on low speed, slowly add the oats and flour. Mix just until no large clumps of dry ingredients remain.
Next, add the chocolate chips and M&Ms and gently fold them into the cookie dough.
