M&M Oatmeal Bars (Made with baking mix!)


*If you have a service member overseas, these M&M Oatmeal Bar cookies are my most requested recipe to send. They travel very well and stay moist. I’ve had packages take as long as three weeks to arrive, only still get rave reviews when I’d tucked these bars inside! If you can, send a package. It make a world of difference!


These M&M Oatmeal Bars were almost impossible to get a photo of. It seemed a soon as I cut them they started flying off the platter. Finally, I was forced to hide this little guy and he had to pose all by his lonesome :(. Poor little cookie, its not his fault he’s moist and tender, tasting of brown sugar and butter and dotted with candy coated chocolates.

Fortunately, these things are a snap to make. They may actually be the easiest cookies I bake come to think of it. I first discovered these M&M Oatmeal Bars two years ago. It was ten o’clock at night and I had already gone to bed. Suddenly, the thought occurred to me that I really should make my daughter’s preschool teacher something because I hadn’t baked for her in a while (We miss you, Miss Rose!).

I immediately thought to the Pioneer Baking Mix in my pantry as I had been cruising their website earlier for recipes. I was also curious as to what a cookie made with baking mix would taste like. Thirty minutes later, two pans of these sat cooling on the counter and I was in bed again, this time only dreaming of baking rather than getting up to actually do it. *You can substitute Bisquick if you like.

For those who may not know me I want to say yes, it is completely logical to decide to bake something on the spur of the moment, no matter the hour :). I just love to feed people. 🙂


To make these M&M Oatmeal Bars you’ll need: Brown sugar, old fashioned oats, vanilla, Pioneer Brand Baking Mix, Candy Coated Chocolate Candies, a stick of butter, and One Egg.

Now the original recipe called for both light and brown sugar but I just use whatever I have on hand, which is light in this case. I have also made these with quick oats and they have been just as wonderful.


In a mixing bowl, place oats and brown sugar.

Check out my bowl, I’m going to show you the outside view here in a minute.


Add egg.


Melt butter in microwave and pour in.


Add vanilla.


Stir all of that up. Normally I use an electric mixer and I do recommend that but I was feeling lazy and it honestly wasn’t difficult to just stir it all up good with a stiff spoon.

Of course, then again, I am a professional. ~snickers~ Just kidding. 🙂

Its cute when people take me seriously. 🙂


Toss in your candies.

Remember when blonde jokes were all the rage? You can only imagine how many I heard! I loved them though, so darn cute!

Why did the blonde get fired from the M&M factory?

She kept throwing away all the ones with “W’s” on them.



Spray an 8×8 pan with cooking spray. Y’all know I don’t even buy name brand in that, either.


Pat it out into your pan.


Then let your kids put more M&M’s on top. Katy likes to push hers down into the dough a bit.


Oh look, this is that bowl I used to mix this up in. I have a thing for antique mixing bowls and depression glass. I see no reason to spend money on modern things when I can put money into something of real value with a history to it. This is a Tulip pattern Fire King bowl and I have a whole set of them, thanks to Southern Plate!

One of these days I’m going to have to devote a post to all of my neat antique dishes that y’all have helped me buy.


Now bake the M&M Oatmeal Bars at 350 for about twenty minutes. Mine always take about twenty five minutes.


Voila! Easy Peasey, delicious, buttery tasting, brown sugar lovin’, kid pleasin’, done in a jiffy even when you start them at ten o’ clock at night, COOKIES!

I just love my baking mix!

  2. Thank you so much for posting these. I can’t wait to make them. This will be good for my five year old to help me with. He loves to help.

      I honestly cannot tell you how much personal fulfillment I get from doing Southern Plate and to hear that people like my site and even appreciate what I am doing is just icing on the big old, gorgeous cake that I get to experience every day!

      Let me know how your little man likes them! My son LOVES to cook with me!!

  3. They look great, and I really want to try these! What if I can’t find the Pioneer Brand baking mix? Will bisquick work? Thanks!

    1. Hey Kira!
      Hopefully you can find the Pioneer because I’m not kidding, that box of the other stuff is a ginormous pain in the…~clears throat~
      But yes, another baking mix should work fine. I’ve never tasted it with another baking mix and I’ve never actually used one other than Pioneer for cookies but it should still work .

      Let us know how it turns out!

      1. Hi Kira,
        About finding that fabulous Pioneer mix, I looked on the Wal-Mart website for Pioneer products by entering my zip code. I did not find ANY in the state of Pennsylvania, nor nearby surrounding big cities in other states. Wah. I guess that I will have to have GA family and friends to ship it to me or just buy it online. Good luck because those M&M oatmeal bars are a huuuuge it at my house. It would be worth the effort to try to get this baking mix. Awesome!

  4. My daughter is home today because her daycare is closed since we had some snow yesterday.

    She saw the email with this recipe and said we HAD to make them.

    This will be my firs recipe with the baking mix. I might even make the biscuits to go with dinner tonight!

    1. Bless her heart! I love it when kids get excited about cooking though, I bet she’ll be so proud! Isn’t it precious when all you do is have them put some M&M’s on top and that is enough for them to claim it as their own dish!

      You let me know how it turns out and thank you!
