These chewy Peanut Butter M&M Cookies are bursting with peanut butter flavor and peanut butter M&M’s throughout!

Peanut Butter Overload

I was recently at the store and picked up some Peanut Butter M&Ms for the hubby (they’re his FAV!). I realized I had never used them in a dessert before and had never tried making cookies with them.

What resulted was a batch of cookies that had a peanut butter base, crushed PB M&M’s throughout, and PB M&M’s on top. In other words… Peanut butter overload! But in the best way, of course.

The whole family loved these cookies so much. But, I mean, you can’t go wrong with a peanut butter + chocolate combo (extra emphasis on peanut butter). 😉

How to Make Them

DOUGH. Cream butter, oil, peanut butter and sugars in mixer. Add eggs and beat until fluffy. Add dry ingredients and mix well.

M&M’S. Add crushed M&ms and mix until well combined. Place on greased cookie sheet and add 3-5 M&Ms to each cookie.

BAKE. Bake at 350 for 7-9 minutes. ENJOY!

Baking tip: Overbaking can cause these cookies to dry out and lose their chewy texture. Take them out of the oven when the edges of the cookies have browned, but not the tops.

Modifications

I modified one of our Chocolate Chip Cookies Recipes and added the M&Ms and a little peanut butter. What I love about that recipe is how easily it can be changed up based on the holidays and all the different M&Ms that come out with each holiday. Can’t wait to try other versions of this cookie with:

  • Butterfinger Baking Bits
  • Caramel M&Ms
  • Peanut Butter Chips
  • Milk Chocolate Chips

I think no matter what “addition” you make, the cookie always results in a chewy treat that the whole family will enjoy.

Storage Tips

Storage: Keep them in an airtight container for 5-7 days. You can also freeze them for up to 3 months. 

Freezing dough balls: Drop the dough balls onto a baking sheet and place it in the freezer. Once they are solid transfer them to a freezer Ziploc. They can be stored for up to 3 months.

    Recipe doesn’t say when to add vanilla. I added it with the eggs.
