These Peanut Butter M&M Cookies are our new favourite cookies! What could be better than M&M cookies that are peanut butter? The flavours are a match made in heaven! Make them into Christmas cookies as well by using Christmas M&M’s!

Peanut Butter with Colorful M&M Cookies

This summer we were so darn busy camping every weekend that I barely baked a cookie. Oh, fine, I know I baked up my skillet cookies and desserts while camping, but it’s been a long time since I’ve fired up the KitchenAid stand mixer and really delved into a batch of cooking baking. Muffins? Ha! I don’t think I made a single batch this summer!

So back to school means back to the kitchen for me, back to a quasi-schedule (I’m really trying to get back into schedule and it’s not working, more on that another time) and back to baking school and after-school treats for the kids. While these cookies won’t make it into the kids lunches (they have peanut butter in them) they most certainly have made it into the rotation of after school treats.

I have a thing for M&M’s and baking with them. They just come in so many sizes and flavors, each delicious in their own right..and the colors! How can you lose with those bright-colored beauties?

As I am sure you are all well aware I have a peanut butter addiction, especially when it comes to sweet treats. This cookie just makes sense to me, by pairing my favorite flavor in M&M’s with a great cookie base.

The end result is a thick cookie, like my Thick & Chewy Chocolate Chip Cookies, with little peanut butter delights baked into them.

Or these Peanut Butter-Pecan Chocolate Chip Granola Cookies recipe? It uses Bisquick! Get outta town!

How is your back to school going? It’s been three weeks and I keep hoping I’m going to get back into it more…and I swear I just keep forgetting more and more things every week!
