If you like Oreos and M&M’s, these are the bars for you. Is there anyone who doesn’t like Oreos and M&M’s? 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 small bag of M&M’s that appear to have most of the reds and browns picked out. 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 Oreo bars 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.

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

The crunchy shells of the M&M’s, 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 clean-out endeavors. They’re tailor-made for your trashy eating enjoyment. Live a little, it’s fun!

What’s in These Oreo Bars?

To make these Oreo and M&M’s cookie bars, you’ll need:

  • Unsalted butter
  • Egg
  • Light brown sugar
  • Vanilla extract
  • All-purpose flour
  • Oreo cookies
  • M&M’s

Melt the butter, then whisk in the egg, brown sugar, and vanilla. Add the flour and mix until just combined. Then, fold in then crushed Oreos.

Turn the batter into a greased 8×8-inch pan. Sprinkle with M&M’s just before baking.

Bake these Oreo bars until a toothpick inserted in the center (if you can find a bare patch to test) comes out clean, or with a few moist crumbs, but no batter.

Can I Use Different Flavors of Oreos?

Yes! Use whatever variety of Oreos you have on hand. Different flavors of Oreos will work here, as will Double Stuf.

Can I Use Different Flavors of M&M’s?

Yes again! Any kind of M&M’s can be used in these Oreo and M&M’s cookie bars.

Can I Use Granulated Sugar Instead of Brown Sugar?

No, you must use light brown sugar in this recipe. Granulated sugar isn’t sticky enough, which will result in a different texture.

Can I Double This Recipe?

Most likely, yes. You’d need to bake the Oreo bars in a 9×13-inch baking pan.

Store these Oreo cookie bars in an air-tight container at room temperature. They’ll last about a week.

Can I Freeze These Oreo Bars?

Yes, but just note that M&Ms can sometimes lose their color and bleed a bit upon freezing.

Tips for Making Oreo Bars

If you don’t have Oreos or M&M’s, 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 fun-sized 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&M’s are great but so are a lot of other things. Use the recipe as an opportunity to use up your odds and ends.

Ingredients

  • ▢ ½ 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*
  • ▢ about 1/2 cup M&M’s , I used plain, use your favorite flavor or other chopped candy

Instructions

  • Preheat oven to 350F. Line an 8-by-8-inch baking pan with aluminum foil, spray with cooking spray; set aside.
  • In a large, microwave-safe bowl melt the butter, about 1 minute on high power.
  • Wait momentarily before adding the egg so you don’t scramble it. Add the egg, brown sugar, vanilla, and whisk until smooth.
  • Add the flour and stir until just combined, don’t overmix.
  • Stir in the Oreos.
  • Turn batter out into prepared pan, smoothing the top lightly with a spatula.
  • Evenly sprinkle the M&M’s over the top, lightly pressing them down with your finger or a spatula.
  • 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.

Notes

    • Note: 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.
  • Bars will keep airtight at room temperature for up to 1 week, or in the freezer for up to 6 months.
