    Chewy peanut butter M&M cookies are always a welcome treat at our house. Baking them into a big skillet cookie makes the process even easier and gives you lots of the best chewy center parts.  It is peanut butter and chocolate cookie goodness at its finest!

    This post was originally from 2015.  I thought it was high time to make this bad boy again.

     When I pulled up the post, the pictures of Little Dude melted my heart.  He was always been such a helper.  

    I couldn't bare to take those pictures out. He is just too dang sweet. But I did update the pictures of the cookie itself.

    I will let you read the original post and see the fun pictures of little dude from when he was an itty bitty sous chef.  

    I don't know if you guys know this or not, but I have a sweet tooth.  I thought I might go ahead and fess up to it!  

    I also love all things chocolate and peanut butter.  I mean, that does go without saying right?  So I just couldn't help myself when I saw a bag of peanut butter M&Ms on sale at the store.

   I had been wanting to make some cookies, but sometimes cookies take too long!  You have to wait for the butter to come to room temperature, make the dough, put it back in the fridge to firm up, scoop the cookies, bake the cookies. 

   I am a little impatient sometimes (keep your comments to yourself, MiMi!) so I need to have a shortcut.

   A skillet cookie solves some of the time issues.  You can use melted butter and can bake it right away because you don't have to worry about the cookies spreading too far.  Plus it just takes one trip to the oven, no worry about doing a sheet at a time!

   The melted butter also made it much easier for Little Dude to stir as well.  So it was win, win.  

    He has so much fun helping in the kitchen.  For this project he got to crack the eggs, dump the ingredients in the bowl, and stir them up.  

    He also enjoyed pushing the dough  into the skillet and spreading it around.  But his favorite part was putting some more M&M's on top.  

    Our cookie might have been missing an M&M or two, but it was still delicious.

   The cookie slices best if you wait a while first.  Little Dude and I couldn't wait, so we had crumbly but delicious first slices.

     My husband and a friend were installing some siding for a couple of friends, so Little Dude and I delivered some pieces to them.  The extra wait time made those pieces come out much better.

    We also loaded up some pieces in the wagon and walked them over to my brothers' house.  Our cookie delivery service did not get any complaints!

   This cookie is everything you would want from a skillet cookie.  It is thick and soft in the middle with just a little bit of crunch around the edge.  But don't take it from, try one yourself!

Prep time: 10 MinCook time: 35 MinTotal time: 45 Min


  • 1/2 cup butter
  • 1/2 cup peanut butter
  • 3/4 cup packed brown sugar
  • 1/2 cup granulated sugar
  • 1 large egg
  • 2 tsp vanilla
  • 1 tsp salt
  • 3 T milk powder
  • 1/2 tsp baking powder
  • 1/4 tsp baking soda
  • 1 cup all-purpose flour
  • 3/4 cup whole wheat flour (you can use all all-purpose)
  • 1 bag peanut butter M&M's


  1. Preheat oven to 350 F
  2. Melt butter in mixing bowl, then stir in peanut butter.
  3. Mix in brown sugar and sugar and stir well.
  4. Add in egg and vanilla and stir until completely uniform.
  5. Stir in the salt, milk powder, baking powder and baking soda until really well mixed.
  6. Stir in flours until just combined. Fold in most of the M&M's, reserving some to place on top.
  7. Press into a 9" skillet or cake pan. Arrange remaining candies on the top of the cookie.
  8. Bake for 30-35 minutes.
  9. (This is the hardest part!) Wait for at least 45 minutes before cutting and serving. If you jump the gun, it will still taste great but will not hold its shape.

  1. That looks amazing! Pinned for reference. :)

  2. 1.. xoxoxoxoooooo. Those pictures of Jaxon helping are priceless. I can tell he is working very hard to be a good helper.
    2. Peanut Butter M&M's are my favorite. This looks like the perfect good. (Whole grains, peanuts and chocolate are good for you). I need to remember to stir in a few chocolate chips when I make this. (For the health of it 😏)
    3. Let me know when a home is for sale in your neighborhood. I want in on this special cookie delivery service. More to see you and Jaxon than the cookies, but I would take them off your hands.
    4. I would never pass judgment on someone's lack of patience. Have you met me? Hello. This is why I love the Texas style sheet cakes and Bundt cakes.
    5. I wonder if you melt the butter in the cast iron skillet and kept it hot (like I do for skillet cornbread) if it would make a crispy and buttery crust? Just think. Undercooked just a tad so we have a gooey center and crisp edge. Oh my goodness. GENIUS
    6. Did I mention that grandson of mine? WAY TOO PRECIOUS

    1. You should definitely move to the neighborhood. We deliver cookies within a one wagon pull's distance!

  3. These looks so good! I love those peanut butter m&m's. Actually, we love anything peanut butter :) Your son looks so cute helping. I love when kids get in the kitchen! I think I may need to invest in a skillet pan after seeing this.

    1. You really should! I love my skillet for all different kinds of things. I think our mutual love of peanut butter could get us both in trouble ;-)

  4. I pinned it, but I'm not making it until I get the rest of my weight off. It is tempting though lol

    Jax is such a doll and a great helper too :)


    1. I should set the same rule for myself! Jax is a very good helper, we have the best time together!

  5. Oh, wow! Those look delicious! How fun that you got to make it together!

  6. Oh my! Looks yummy and fun to bake :) I'm adding it to my 'try list'!
