Everything delicious is loaded into these peanut butter oatmeal chocolate chip cookies with m&m’s! We have even updated this recipe to include oatmeal now, so it just got even better!

We aren’t really sugar cookie people at our house so when it’s time to bust out cookies we tend to go with chocolate chip, but my true love is peanut butter and chocolate. This old recipe is being brought back up to the front so you all can make delicious peanut butter chocolate chip m&m cookies and I promise it will be the best cookie you have all week (unless you eat any of our other cookies too in which case those are also the bomb diggity). But first, peanut butter chocolate chip m&m cookies.
I have tested this particular recipe half a gazillion times, and I truly believe this is the best peanut butter chocolate chip cookie around and it’s even better with m&m’s. I love using mini m&m’s because I love that you get little nibbles of m&m’s in every bite.

Do Peanut Butter Cookies Need to Be Refrigerated?
Peanut butter cookies do not need to be kept in the refrigerator.
To prevent peanut butter cookies from becoming stale, cover them with plastic wrap or keep in an airtight container.

Can You Freeze Peanut Butter Cookie Dough?
To freeze, roll into a log, and tightly wrap in plastic wrap, then into freezer bags.
Freeze for up to 3 months, then let it thaw in the refrigerator for an hour or two before rolling into balls or slicing and baking.
Or, you can roll into balls and place on a cookie sheet to freeze.
Once frozen, place in a freezer bag and store in the freezer until you are ready to bake them.

Can You Keep Chocolate Chips in the Freezer?
Semi Sweet Chocolate chips will maintain best quality for about 2 years in the freezer.
Milk chocolate chips will keep for 1 year.

Tips
The only thing you need to be aware of is that the more candy you add and the bigger they are the less cookie dough there is to create a yummy cookie.

This recipe sounds great! However, can you please tell me if these cookies are chewy? Soft? or do they end up crispy?
Thank-you!!
Sweet Basil
Hi Renee! They are slightly crispy around the edges and chewy in the middle. You will love them!! Enjoy!
Renee
Thanks for the reply. One more question. I see the recipe does not list butter, is that correct? No butter in these cookies?
Sweet Basil
Hi Renee! Yes, that’s correct! You get all the fat you need from the peanut butter. I’m actually in the middle of updating this post, and I haven’t taken new pictures yet. Your end result will look a little different than the photos in the post, but this recipe is seriously heaven if you are a peanut butter lover!!
