Easy M&M cookie bars are guaranteed to be a family favorite. They are quicker and easier to make than individual cookies, making this a recipe perfect for beginners.
Cookie bars are not just chocolate chip cookie dough in bar form. Therefore, you will notice there is no leavener such as baking soda or baking powder in this M&M cookie bar recipe, like there is in chocolate chip cookies.
This is because adding those ingredients will make the cookie bars more cakey than chewy. We want cookie bars with chewy centers, therefore no leavener is needed.
