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! 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.

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.)

*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!

      PS if you don’t have brown sugar you can add a tablespoon of molasses to 1 cup of sugar and there you go brown sugar.. I learned this on Chistmas eve when I needed I ran out and the stores were closed.

  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.

Southern Plate is the first thing I look at when I boot the computer up. God Bless and Happy Cooking.

    1. Tracy, thank YOU so much for such a wonderful compliment!!!
      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!
