BROWNIE OREO ICE CREAM BARS!! Brownie-bottomed, oreo-topped, hot-fudge smothered, ice cream-covered dessert bars. So easy to make, perfect for a hot summer day, and absolutely delicious!

These Brownie Oreo Ice Cream Bars are one for the books! Fudge-y rich brownies are topped with chopped Oreo® cookies that have been smothered in hot fudge. Then they get topped with Cookies & Cream ice cream and we add a layer of whipped topping with a few more crushed Oreos for good measure — more is more with this dessert!

Brownie Oreo Ice Cream Cake

In an attempt to make the ultimate ice cream cake for my husband’s birthday, I combined all his favorite desserts into one show-stopping treat. It was so memorable that he now requests it every year!

Brownies, Oreos, hot fudge, ice cream, and whipped cream — who can resist?!

Brownie Oreo Ice Cream Cake Layers

Start by making fudge brownies: 

We begin with a boxed mix for this recipe. Brownie mixes are tasty and convenient, especially since the goal is for this dessert to be quick and easy. If you want to make your brownies from scratch, use your favorite brownie recipe in place of the mix in this recipe. (Just make sure it fills a 9×13-inch pan.)

My personal favorite mix for this Brownie Oreo Ice Cream Cake: Betty Crocker’s Fudge Brownie Mix®. There are different versions of this mix, so make sure to get the mix that will fit a 9×13-inch pan. Any brownie mix will work, as long as it’s intended for the larger pan (not an 8×8 or 9×9 pan). As far as homemade goes, I do have this delicious Gluten-Free Brownie recipe on my site that can be used in place of the boxed mix (just leave off the frosting).

Oreo Cookies:

While the brownies are baking, coarsely chop the Oreos. The brownies are ever so slightly under-baked so the chopped Oreos can be pressed in and adhere nicely to the brownies. To ensure Oreos end up in every bite, be sure to press the cookies in one even layer (as opposed to just scattering them on top).

Hot Fudge:

Once the cookies are in place, we spread a jar of hot fudge on top. This takes a bit of patience! I recommend warming the fudge first in the microwave and then adding large dollops all over the top of the Oreos. Use the back of a large spoon to gently coax the fudge into one even layer.

Cookies & Cream Ice Cream:

The next layer on this Brownie Oreo Ice Cream Cake is the actual ice cream! Use your favorite cookies and cream ice cream for this layer. Not sure where to start? The Washington Post has taken care of the testing for you. Tillamook® is a favorite of ours (not sponsored).

Whipped topping:

Finally, we top this Brownie Oreo Ice Cream Cake with whipped topping. You can certainly make your own (how to make whipped cream) or just use a container of thawed, frozen whipped topping. Once everything is set, feel free to add some leftover crushed Oreos.

Process shots-- images of the hot fudge being added on the top, ice cream being spread over that, whipped cream going on top of that, and Oreo crumbs being sprinkled on top.

Brownie Oreo Ice Cream Cake Tips

  • Make sure to keep the bars in the freezer as much as possible while making them. If the ice cream gets too soft and melty, it tends to turn icy when re-frozen.
  • Under-bake the brownies ever so slightly. Since they’ll be frozen, they firm up and get quite hard; I’ve found if the brownies bake the full time indicated on the package, they’re too hard in these bars (especially contrasting with the soft ice cream and hot fudge toppings).
  • Try some fun flavor variations. Get creative with the ice cream you add to this Brownie Oreo Ice Cream Cake — instead of cookies and cream, try vanilla bean, cookie dough, or even chocolate!

Quick Tips For Serving

  • Line the pan with parchment paper for easy cake removal and serving. Leave a parchment paper overhang to pull the bars from the pan and then cut them into bars.
  • For cleaner and easier slicing, run the knife under hot water and then wipe off with a towel between slices.
  • Use a very sharp knife — they cut so much easier!
  • Allow Brownie Oreo Ice Cream Cake to stand for 5-10 minutes at room temperature before cutting, so it’s slightly easier to cut into. 


  • Store leftovers in the freezer in an air tight container for up to 2 months.

  • 1 package (18.4 oz.) fudge brownie mix + ingredients called for Note 1
  • 27 regular Oreos, divided (leave 3 for topping)
  • 1 container (11.75 oz.) hot fudge topping
  • 1 container (48 oz.) cookies and cream ice cream
  • 1 container (8 oz.) frozen whipped topping completely thawed
  • Optional: parchment paper


  • PREP: Line a 9x13-inch pan with parchment paper leaving an overhang for easy removal. Set aside. Preheat the oven according to brownie package directions.
  • BROWNIES Prepare the brownies according to the package directions. Bake the brownies according to package directions, but slightly under-bake the brownies by 3 minutes. The brownies should be set, but soft, so they'll cut nicely when frozen. Remove brownies from the oven and allow them to cool for about 20 minutes.
  • OREOS: Coarsely chop all but 3 Oreos (I cut each cookie into 4 even pieces). Gently press the chopped cookies in one even layer on top of the brownies.
  • HOT FUDGE: Warm the hot fudge for 30 seconds and then add dollops of the fudge all over the cookies. Working carefully and slowly (this requires some patience!) use the back of a spoon to press the hot fudge into one even layer. Freeze for 10 minutes.
  • ICE CREAM: Let ice cream stand at room temperature for 5 minutes. Remove the pan from the freezer and scoop out large scoops of ice cream all over the hot fudge layer. Use a spatula to gently press down and smooth the ice cream into one even layer.
  • FREEZE: Freeze for at least 2 hours and preferably overnight.
  • WHIPPED TOPPING: Spread completely thawed whipped topping evenly over the ice cream and, if desired, garnish with the 3 reserved crushed up Oreos (no need to remove the filling; add full Oreos to a bag and crush with a meat mallet or wooden spoon and then sprinkle over the bars). Cover bars and return to the freezer for 30 minutes.
  • ENJOY: Set out bars for about 5 minutes to slightly soften before cutting into bars. Use the parchment paper overhang to remove the bars from the pan. Run a very sharp knife under hot water and then wipe off with a towel between slices. Promptly return any leftover bars, covered, to the freezer.

  1. HELLO best thing to wake up to on a Monday morning. Seriously, I just woke up, and lying in bed perusing some of my fave blogs (you!) and am dying looking at this.

  2. Why would anyone want plain brownies when you can have fudge-oreo-ice-cream topped deliciousness??????? Seriously, Chelsea, you outdid yourself here – this has to be the msot delicious dessert I’ve ever seen! I’m so drooling right now 😉 x

  3. Whoa baby! These look crazy good Chelsea!

    haha my husband is the same way – he always gets mad at me whenever I make anything other than plain vanilla bean ice cream. Now don’t get me wrong, I love plain vanilla bean but I mean there are just so many other options out there!!

  4. Oh my, I need these ice cream bars in my life! I love putting Oreos in brownies, so layering them up with some hot fudge and ice cream sounds like the best idea! They look fantastic. Have a good week, Chelsea! 🙂

  5. 5 stars
    All I can think about is grabbing a few and running away! Brownie, hot fudge, oreos, ice-cream… Your killing me! YUM!!

  6. I love the photos you have of how this ice cream bar was made!! It looks crazy easy and impossible to stop eating!! Ice cream anything is the way to go in the summer. I usually reach for the cookies and cream so i’m all over this Chelsea! Thanks for sharing 🙂

  7. These look amazing!! Is it a sign that I should make them that my son happened to pick up Oreo’s when we were at the grocery store today?! I’m thinking yes!

  8. There is no way this wouldn’t be a hit as a dessert. Everything in it is delicious, but it also has the look of something expensive if you got it at a restaurant.

  9. Note to self: do not look at Chelsea’s blog before 9am, because you will be incredibly hungry. Like seriously, really?! You’re killing me! These look beyond amazing! NEED!!!!!

  10. Haha my husband says the same thing! But I totally love how you decked out these brownies – they look crazy amazing!! Pinning:)

  11. These bars look fabulous! I’m a huge chocolate and oreo lover and I TOTALLY understand trying to “make it better” haha so guilty of that! It clearly worked here though!

  12. Can you keep brownies in pan and just add the rest of ingredients? If not then when you take brownies out of pan, how do you keep everything together so it doesn’t melt. Also how would you cover this to put in freezer?

    1. Yes absolutely keep the brownies in the pan. When I say remove – I mean from the oven. Once the brownies are cooled and topped with everything I cover the 9 x 13 pan with tin foil and place it in the freezer. It freezes in the pan like that and then you can cut into bars once everything is frozen and return any leftovers to the freezer.

  13. after freezing the cake.. is the brownie layer completely frozen and is it hard to cut through?

    1. Nope! It does well even after being frozen. I wouldn’t leave it in the freezer longer than a 2 days though because I could see it getting pretty hard after that.

  14. 5 stars
    OMG, this looks amazing! I have a huge family party coming up, so I will definitely be making this! My only question is that do the oreos become soft after putting the hot fudge topping? Or will they stay hard, because they are put in the freezer?

    1. I don’t know how helpful this answer is, but kind of both. They aren’t like soggy since they are frozen, but they aren’t super hard like eating an oreo plain would be.

    My daughter wants this “cake” for her birthday, and pinned it to her birthday board on Pinterest. Before reading your post, I thought I might layer this in a spring form pan and then coat in whipped cream and sprinkles to give it a more festive look. When you made it this way, did you have a brownie bottom, oreo, fudge, ice-cream middle and then another brownie on top, or did you layer it a different way?

    1. Hey Cassie! I actually did it the first way — brownie bottom, oreo, fudge, ice cream, and whipped topping. Hope that helps!

  16. Hi Chelsea! How long did you have to leave this in the freezer for? I am thinking about making it for father’s day but have limited time so wanted to check. Thanks!

    1. I’d say at least 6-8 hours, it really depends on how melty the ice cream gets and how cold your freezer is 🙂 I hope that helps!

  17. 5 stars
    Made this for the 4th of July and it got rave reviews! Only change I would make the next time is to cut up the Oreos before layering them on top of the brownie, because after frozen, they were difficult to cut through. Didn’t stop us from devouring the whole pan but would certainly allow us to shovel it in our mouths more quickly next time! 😉

    1. Thanks so much for the comment Kergie! 🙂 I’m so thrilled it got rave reviews!! And that is a great idea to cut up the oreos! 🙂

  18. So excited to make this! My brownie box says to use two boxes of brownie mix for a 9x 13 pan. Did you use one so its makes for a thinner layer?

    1. As long as the mix is around 18.4 ounces it will be great in a 9 x 13 🙂 And yes, you’re correct, its supposed to be thinner for all the other layers 🙂

  19. 4 stars
    I agree with Kergie. It was very difficult to cut, but we loved it anyway. I am making this for my grandson’s birthday (he requested it – he’s going to be 7!) but this time I am going to use mini oreos so it will be easier to cut. I will let you know how that goes!

    1. I think the mini oreos are a great idea! Or even chopping up regular sized ones could help and make it easier to cut 🙂 So happy you enjoyed it and are making it again for your grandson! Happy birthday to him!

  20. 4 stars
    This didn’t work out so well for me. The brownies and oreo cookies were hard has rocks once frozen and the ice-cream never refroze enough to cut properly–so it was an oozing mess. Tasty, but messy. Once the brownies and cookies thawed, it was a good base to add more ice cream…I just wished I had made brownie cookie sundaes instead!

    1. I’m so sorry to hear that Remi! It sounds like the ice cream might have gotten too melty or didn’t refreeze for long enough. Did you use a lower calorie or fat free ice cream?

  21. You say in the recipe to chop the cookies but in the picture you just lay them whole! Is one or the other better?

    1. Yes, after making these so many times, I’ve found it’s best (cuts easier and more cookie per bite) with the cookies chopped! Thanks for the question!

  22. Hey Again!

    So, these were absolutely amazing but I have one more question. I had a little trouble getting the brownie to come up from the pan when I cut them. Do you think it ended up too thin? or froze too long? Just curious.

    Either way they were great!!

    I made them for my husband’s birthday! and he loved them.

    1. I’m so happy your husband enjoyed them! It seems like maybe the brownies were a little over-baked; if you make these again pull them out 2-4 minutes earlier and they should be great!

  23. I haven’t made this yet, but I want to. I just don’t know what and where I buy hot fudge sauce? Can I possibly use chocolate syrup instead?

  24. This looks amazing! Wish I had found this in the summer. But still want to make now!!! Question – do you think if I added a layer of caramel instead of (or in addition to 😉) the fudge layer that it would set okay? Or better to just drizzle on the top at serving? Thanks!!!
