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.)

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!

  1. First off I want to say that as a full time college student your recipes are perfect for me!! They’re so simple and quick! And fabulous of course 🙂

    And for the third time this week I decided to try a new one.
    So this morning I made these and they turned out great!!

    but…. (yes, there is always a but!)

    Shortly after making them (and eating only one) I covered the pan with foil and set it next to the fridge. Not even two minutes later a wine glass fell from the top of the fridge and shattered… right through the foil and on my precious cookies!

    Needless to say, my second batch of the day is currently cooling on the counter. And I’m hoping to eat more than one this time! Thank you for this recipe along with every other one on the site. Your time and effort is much appreciated!!! 🙂

  2. I just made this these and another winner in our house!! thank you so much for a quick and inexpensive cookie snack for my family.

  3. These are great to send to school..My grandson’s class love them! They can have snacks like these on Friday’s and they always ask for these or my granola bars.

  4. I don’t usually leave comments for recipes but OMG these were phenomenal! Ooey Gooey perfect cookies-best I’ve ever had in my life. WOW WOW WOW!!! I couldn’t find Pioneer Baking mix so ordered it online. Made several batches over the holidays. Craved them last week but didn’t have anymore Pioneer mix so I used Bisquick–UGH, big mistake, not very good–you have to use Pioneer or you might as well not make these. TY so much for this recipe, it is now my favorite!

  5. I don’t suppose anyone knows what could be used instead of Biscut and Baking Mix? or Bisquick? I live in Australia and I’ve been unable to find an equivalent down here. Boo Hoo Sounds easy and divine!

  6. I have that bowl!! I love it!! It was my dad’s. I almost fell out of my chair when I came across that picture. Do you know anything about it? I also have another old bowl and some cookie jars that were my parents. I love them and use them. I am forever afraid I will break one.

  7. I just made my 1st batch of these… and goodness gracious… time to make another pan cus the pan I just made are almost gone. THESE are SOOOOOOOO good and so easy! This will be my next item to ship to a solider in Iraq. I will just vacuum seal them and ship. They will be awesome! I am sure of it! Thanks soooooooo much Christy!
