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.

Half-eaten package of Oreos. Check.

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.

  1. Definitely a fan of recipes that use up random pantry ingredients… especially when the result is something as decadent and delicious-looking as these bars!

  2. These look fabulous! Just so packed full of amazing stuff :D And I have half a bag of M&M’s and 3/4 pack of Oreo’s right in my kitchen cupboard now, they’re telling me to make these!

  3. Oreos are a total guilty pleasure. I can’t stop eating then, I even would pick them over most of the girl scout cookies.
    These bars look fantastic, perfect “bake sale” treat.

  4. So somehow I didn’t know about you till right now. Where the hell have I been? These photos are GORGEOUS!

  5. Well, now I want these. Right now.

  6. Oh me gosh! M&M’s and oreos are finally married!!! Heavenly! And I absolutely LOVE your oreo to batter ratio!!! :-D

  7. This cookie looks like a rainbow! It consists of my favorite cookies and candies. And the recipe is rather easy, which makes it more available to bake in any day of a week. I think that my kids will enjoy such cakes!

  8. Gah! These bars look absolutely perfect! Love that chewy centre!

  9. I seriously believe some greater force gravitates me toward anything involving Oreos. Needless to say, then, these caught my eye! The M&Ms just take them to the next level. I love bar recipes like this, just throwing together what you’ve got – baking simplicity at its best!

  10. There is something about M&Ms that just make me happy. I love seeing all those bright colors on top of this incredible bar. This one I have no choice but to make for my hubby – this is like his dream bar!

  11. Oh how I love loaded cookie bars!!!! These are amazing with the Oreos. I hope the move is going good!

  12. I love cookie bars (so much faster than cookies!). These look fab, my Wednesday needs a couple!

  13. Chewy center! Awesome. I think I know what my kids will be making on the weekend. Thanks for this.

  14. I used to stand in Dairy Queen paralyzed with indecision about m&m or oreo blizzards (before the days of the cookie dough, at which point things got even worse!) It would usually take me so long the cashier would take pity on me and offer to make me one with both!

  15. Now, this is my kind of dessert (if I could eat it). I love multiple layers of texture and crunch. You have chewy in the bar, hard crunch in the m&ms and oreo and altogether it is mouthwateringly delicious!! Wow. I don’t have any of those ingredients, but I am tempted to buy them just so I can smell them when they are done! LOL! I still day dream over those white chocolate, frosted bars of yours. Oy! Day 11 tomorrow of the cleanse…cannot wait to be done!!! Watermelon never sounded so good! :-)

  16. M&Ms and Oreos that come together in 1 glorious bar?! Hell yes! Love that it comes together so easily too!

  17. Oooooh I love how these can just be “clear out your pantry” bars!

    But, um, obviously I love Oreo’s and M&M’s, and now I’m thinking how good peanut butter M&M’s would be in theeese

  18. Load me up- these look fantastic!!

  19. I really hope there is no one that doesn’t like M & M’s and Oreos! Sheesh! And holy wow are these awesome Averie! Chewy cookie soft-ish baked Oreos, a little candy crunch– LOVE them!!!

  20. Loaded, indeed! I love how festive these sweet bars are – perfect for preparing with and serving to hungry little ones!

  21. Oreos and M&Ms are two of my favorite things! Baking with Oreos is so fun because they can completely change textures sometimes. Crunchy to soft. Love these bars! :)

  22. Hi Averie! I made these today and they are sooooo good! I knew it from the beginning, with oreos and m&m’s you can’t go wrong! :) Thanks for the recipe! :)

  23. All you need is a great base and you can mix anything in! This particular combo looks fantastic. Best of luck in the moving process!

  24. Wow, wow, wow! These look so amazing, Averie!

  25. Averie, it’s official.. your blog is now my new favorite dessert blog. These cookies look like heaven on earth!! I can’t wait to try them out. Might bake them closer to Halloween and bring them in as a Halloween treat for coworkers because I certainly don’t trust myself with these.
