Some days call for a good cookie. Those days that call for cookies might be anything from kids heading off to their first day of school to realizing that you haven’t had a cookie in a couple of months.

Yes, that is what I realized the other day. It just didn’t seem right to go longer than 2 1/2 months without eating a cookie.

Since I had gone so long without eating a cookie, I didn’t want just any cookie. It had to be a “good” cookie. 

These M&M peanut butter oatmeal cookies have all of the most important components of a good cookie. They are chewy, full of peanut butter, nutty from the oats, and contain just the right amount of chocolate.

These cookies look just perfect! I love oatmeal cookies - they are the best - and compared with M&M's they can only be that much better. And much more fun to eat with all the colors! I will make these the next time I am baking cookies. Thanks for sharing :)
