Peanut Butter M&M Cookies, pretty much the best recipe ever ohsweetbasil.com

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.

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.
