Oreo Brownies With Buttercream Frosting

Let me just say this now… these are to die for.    My mom made these a few years ago, called them Cookies and Cream Brownies, and they instantly became my favorite brownie ever.   I know people have been putting chocolate frosting on brownies for years, but as much as I love chocolate,  the vanilla buttercream on a brownie, oh my word.  DELICIOUSNESS.

You could certainly make your brownies from scratch, but I’m one of those people that grew up on box brownies, and when I want a brownie, I usually want the good old box kind.     So here’s what you need…

Your favorite brownie mix (or the one that was on sale!), Oreos and vanilla frosting.  You can absolutely use canned frosting.   I prefer homemade frosting, and had all the ingredients on hand, so homemade it was.   Don’t you love my combo of organic milk and Crisco?  I’m guessing the Crisco is not quite organic.

Prepare the brownies as instructed on the box.

After mixed, you will add broken and crushed up Oreos to the batter.  You can certainly put your Oreos in the food processor, but I prefer the Ziploc bag and mallet for easy cleanup.

I crushed about half the package of Oreos (for a 13 x 9 size pan of brownies).

I put about 2/3 – 3/4 of the crushed Oreos into the batter, and held the rest back.

Bake your brownies according to the instructions on the box or for the recipe.

Now lick the spoon.  No, wait.  Wash the dishes.  I am ALWAYS confusing those two.   After the brownies come out, let them cool at least 20-30 minutes.   Once cooled, you can skip ahead to frosting or if you like, you can cut the brownies.   I love round brownies (like those from Sugardaddys), so at this point I cut mine out.  Think of it like cutting biscuit dough.

I used a cup, and firmly pressed into the brownies, giving them a slight twist.   If you do this, I do advise spraying a bit of cooking spray on your cup/cutter every few brownies.

Don’t toss the leftover brownies!  You can either eat them (can’t go wrong there) or save them for something else.  I’m planning to make an Oreo brownie trifle with mine.

Now for the frosting.  Either pop the lid open on your can, or make your favorite frosting.  Mine is a very unscientific mix of softened butter, Crisco, vanilla, milk, salt and powdered sugar.   This recipe would be pretty close to what I do.   After preparing the frosting, I put mine into a Ziploc bag.   Frosting brownies can sometimes be a messy task, and I find piping it on works well, and is quite quick.

To put my frosting into a bag, I put my bag into a large solid cup, and fill with a spoon.

After the frosting is in the bag, I squeeze it towards the bottom, and when ready to frost, I simply snip one of the bottom corners off of the bag.

After frosting the brownies, you will want to pull out those left over Oreo crumbs and sprinkle some on top of each one.

And there you go!  DELICIOUS buttercream frosted Oreo brownies.

If you want, you can add an Oreo to each brownie.  I think mini Oreos would work great for this as well.

Now go make these and enjoy one, or a dozen, whatever works best for you.  :)

Check out what you can do with the leftovers…  Make Oreo brownie trifle!  Super simple and a great dessert to let the kids help out with, or even make on their own.

      Sandra, thanks! They are so good and really very easy. One of those desserts that really wows, yet takes so little work. I often make them, and leave them uncut and frost them in the pan, to take as a dessert for friends. If you leave them in the pan they are super quick and easy.

    Oh. My. Goodness! YUM! Oreo’s are definitely my favorite store-bought cookie. Cookies and cream is my favorite ice cream. I love dark chocolate brownies. You basically took everything I love and combined it into one sinful treat. Can you mail me some? ;)

      Jenna, I should – these are WAY too hard to resist. My daughter is eating one now, and scolding me for not making them more often. Now I’m wanting to have them with a scoop of cookies & cream ice cream. Oh my goodness, that would be insane!

    These sound great! I never thought about topping a brownie with vanilla buttercream before, but this cookies and cream combination sounds to die for! Can’t wait to try these. Thanks for sharing!

    Can I just say what a relief to find someone who actually knows what theyre talking about on the internet. You definitely know how to bring an issue to light and make it important. More people need to read this and understand this side of the story. I cant believe youre not more popular because you definitely have the gift.

    My colleagues salute your genius. A variant of whole oreo/brownie mix is yummy. I must experiment further…! :)

      Megan, so glad you like them! Your photos look great. I seriously do not know how vanilla frosting and brownies have not been the standard. No offense chocolate, but the combo is amazing!

    These Oreo brownies look amazing! I was considering using this brownies recipe to make my son’s 2nd birthday cake. Is your icing hard enough for piping and decorating? I want to put a dump truck on it. . .and thought that the leftover brownie mix would be perfect “dirt” coming out of the truck!

      Kasey – I think it would work well for your son’s cake. With icing, I don’t really stick to an exact formula – I vary how much powdered sugar I put in based on what I want to use the frosting for – from thick to thin. If you put in enough powdered sugar, I think it would work quite well. I’d just make sure you have enough powdered sugar before starting (so probably more then one bag) so that you can add enough to get it as thick as you would like. Good luck – I’d love to see pics! And happy birthday to your son! :)

    Loooove! My family & I, husband especially, love our oreos. Definitely going to give these a go! Thanks for sharing! Btw, I use my cupcake pan for my brownies. Good individual servings & no one fights for the crust :)
