Loaded M&M Oreo Cookie Bars

If you like Oreos and M&Ms, these are the bars for you.

Is there anyone who doesn’t like Oreos and M&Ms? I hope not. Or you may be reading the wrong blog.

These bars came to be because I was preparing to move and in an effort to clean out my pantry, I started grabbing things that looked like they’d work together.

A stick of butter, 1 egg, 1 cup of brown sugar, and 1 cup flour. Check. I always have those items on hand.

And if you do, you can make these in 5 minutes without a mixer and they’re ready in a half hour. Love pans of bars for that reason. Fast, easy, no dough to chill.

If you don’t have Oreos or M&Ms, shop in your own pantry for what you do have.

Graham crackers, 4-day old leftover chocolate chip cookies that are past their prime, leftover Funsize candy bars from last Easter, the remains of your last impulse buy at Trader Joe’s like chocolate-covered pretzels or that tub of mini peanut butter cups you’ve been snacking on at midnight, or the nearly empty bag of white chocolate chips that you grab a handful of every time you walk past the cupboard.

You get the point. Don’t buy anything if you don’t have to. Sure, the Oreos and M&Ms are great but so are a lot of other things. Use the recipe as an opportunity to use up your odds and ends.

I’m a big believer in uncluttering my pantry by making odds-and-ends bars every chance I get. I’m also a big believer in bars that are packed to the max with Oreos.

I used my easy, no-mixer, go-to blondie recipe that has served me so well over the years, and I adapted it this time by stirring in chopped Oreos and sprinkling on M&Ms.

It’ll seem like there are more Oreos than batter, and that’s correct. Such a such a good problem to have.

I used Birthday Cake Oreos, which have birthday cake flavored-filling, but don’t go out of your way for them. They hardly seem different from original Oreos to me.

The bars are dense, thick, and packed with texture. The Oreos soften slightly while baking, but retain some crunch.

The crunchy shells of the M&Ms, contrasted with Oreos, and the soft, buttery, moist blondie dough is a texture lover’s dream.

Shopping in my own pantry and widdling down my ingredients before moving was a packer’s dream.

And my family was pretty happy when they had a taste of my pantry cleanout endeavors.

They’re tailor-made for your trashy eating enjoyment. Live a little, it’s fun!

Loaded M&M Oreo Cookie Bars

These dense bars are a texture lover’s dream. There’s an abundance of crunchy chopped Oreos and M&M’s, contrasted with soft, buttery, moist dough. The bars come together in 1 bowl, without a mixer, in 5 minutes, and are ready in under a half hour – great when you need a dessert in a hurry. The recipe is ripe for substitutions, and use it as an opportunity to clean out your pantry and use up your half-eaten bags and odds-and-ends. See blog post for ideas. Pantry cleanout never tasted so good.

Ingredients:

1/2 cup unsalted butter (1 stick), melted
1 large egg
1 cup light brown sugar, packed
1 tablespoon vanilla extract
1 cup all-purpose flour
18 Oreo Cookies, coarsely chopped (I used Oreo Chocolate Birthday Cake Sandwich Cookies; another type of chocolate sandwich cookie may substituted, or about 2 heaping cups of coarsely chopped add-ins including leftover cookies, graham crackers, chocolate-covered pretzels, etc.)
about 1/2 cup M&M’s (I used plain, use your favorite flavor or other chopped candy)

Directions:

  1. Preheat oven to 350F. Line an 8-by-8-inch baking pan with aluminum foil, spray with cooking spray; set aside.
  2. In a large, microwave-safe bowl melt the butter, about 1 minute on high power.
  3. Wait momentarily before adding the egg so you don’t scramble it. Add the egg, brown sugar, vanilla, and whisk until smooth.
  4. Add the flour and stir until just combined, don’t overmix.
  5. Stir in the Oreos.
  6. Turn batter out into prepared pan, smoothing the top lightly with a spatula.
  7. Evenly sprinkle the M&Ms over the top, lightly pressing them down with your finger or a spatula.
  8. Bake for about 20 to 22 minutes, or until done based on add-ins used. Top should be set and edges slightly firm. A toothpick inserted in the center (if you can find a bare patch to test) should come out clean, or with a few moist crumbs, but no batter. Allow bars to cool in pan for at least 30 minutes before slicing and serving. Bars will keep airtight at room temperature for up to 1 week, or in the freezer for up to 6 months.

  5. What’s a half-eaten bag of Oreos? I don’t think it’s something I’ve ever come across. :D

    I love how you can just throw ingredients together and make something pretty! Now I’m craving M&M’s and baking.

  6. I just made some and took it school to share with my friends and we all loved it! definitely saving this one =) thanks for sharing!

  7. These look amazing! Pinning to try later! Oh, and I’m so glad I’m not the only one who eats my baking chocolate chips for snacks. =)

  8. Averie, I love, love, love your cookies, they all look so good!!

  9. Hi! I’ve been dying to make these and I finally made them for my office. Everyone LOVES them! Thank you so much theyre amazing :)

  10. I’m dying for sweets and this just nailed the spot! Definitely making it right now!! It looks so good so I’m sure it will taste just as good ;)

  11. My brother and I have these in the oven at the moment… except we used oreos and a chopped assortment of our favourite chocolate bars (Cadbury Hazelnut, Cadbury Marvellous Creations, and Milk’n’Cookies white chocolate… mmmmmm) instead of M&M’s! Can’t wait for them to be ready, it’ll be glorious! Thank you for an excellent recipe!

  12. Just tried these out! So good, easy to make with great results :)

  13. OMG!!!! Love love love thoughts brownies! My To Do List has all these recipes on it for me to make! The Loaded M&M Cookie Bars made it through a successful 1 hour! My family ate them to fast.

  14. These look amazing! I want to make this for a big group though; can this recipe be doubled for a 9X13 pan?

  15. Would you be able to use pre made cookie dough?

    • Yes you probably could but this dough is so easy, literally takes about 3 mins to stir together, and bite for bite, it’s so much cheaper than storebought, you know what’s in it, i.e. real ingredients, and the recipe was tested using scratch dough in terms of baking time and add-ins it’ll hold.

  16. Hi, I just mde these for my hubbys work. I tested a piece. They’re gonna love it. Really yummy stuff!!

  17. I made these yesterday and gave them to my friends- everyone loved them! They’re so delicious and they were really simple to make which is great considering I mess up everything in the kitchen. They looked beautiful too.

  18. I threw in mini M&Ms, Cookie Crisp cereal, and chocolate chips in the batter. They’re in the oven now! I’m a little nervous though… the consistency came out more like cookie dough than brownie batter.

  19. These bars look so good! I can’t believe it was as simple as just wanting to clean out your cupboards to come up with the idea! I should try that to see what fun creations I could come up with. They sound very simple to make and like there isn’t too many ingredients. For those of us who are learning to cook and bake, simple and few ingredients is the best way to learn, at least for me it is. I can’t wait to try these bars. I was also surprised that the total cook time was only 30 minutes. It seemed like it should have been longer, but the shorter the cook time the sooner you get to eat. There were many other bars you posted pictures of on this blog that look like they would be very good to try as well. I think that they would be extremely delicious with ice cream! The smore brownie looked especially good since I am a big fan of smores in the first place. Well looking at this site it made me very hungry! Keep posting your delicious looking desserts so we can enjoy making them because they look amazing and good!

  20. First of all, your photography is to. die. for. amazing. Anyway, if I wanted to make extra and do it in a 9×13, I’m assuming I should just double the recipe?

  21. I just made these and they are GREAT! So quick and easy! Thanks!!

  22. You have just made half of my family happy! I want to thank you for your wonderful recipe, I made it for a baby shower and now its being requested so much I am making “just because” gifts! Thanks for making me think I can truly bake!

  23. Finally unpacked and settled enough to bake – whew! I’m making a double batch of these (I used an entire oreo bag plus an entire m&m bag) to impress my hubby’s classmates tomorrow. Your recipes never let me down. :-)

    • Thanks for trying this recipe and for saying that my recipes never let you down. This is one of my most popular recipes ever and people seem to love these things so hopefully your hub’s classmates do, too! With a whole pkg of Oreos and bag of M&Ms, it would be hard for them to resist these I’d imagine :)

  24. Do you think i could use whole wheat flour to make these?

    • You could, yes, but I don’t know if it would taste quite the same or with the same texture. I recommend maybe half the amount as whole wheat so the taste/texture doesn’t change too much.

  25. I made the left overs bars for our camping trip tomorrow I used gram cereal, peanuts, snickers, butterfinger, chocolate bars and heath chips I cant wait to try them :D
