Cake Mix Oreo Bars are the ultimate and best cake mix recipe! Soft, fudgy, chocolatey and filled with a layer of cream cheese frosting.
Cake Mix Oreo Bars
I love Oreos. I’m a child of the 90’s and I feel like all my memories growing growing up included a cold glass of milk and a stack of those black and white cookies. When I’m headed to a party, I always bring my number one requested treat along… Homemade Oreos. No matter where I go these disappear quicker than any dessert and everyone begs me for the recipe! I even had a bride request them for her wedding and people kept coming into the kitchen looking for more! I love making my Homemade Oreos but I wanted to reinvent the recipe to be a little less time consuming. No rolling out dough balls, no piping bags, no fuss! So my Cake Mix Oreo Bars were born! And oh my, I’m obsessed. This experiment just killed any plans of a summer diet… whoops.
The Best Cake Mix Dessert
Cake mix desserts are great! These went into the oven in about 5 minutes and while they baked I whipped up the frosting! I used a small sheet pan but you can double the recipe and use a regular sheet pan, use two cake pans, or even just use a regular sheet pan and only press out the dough to one side. Remember, this is cookie dough still, so it won’t spread out like cake batter would! The goal is to be able to cut your finished bake in half and then sandwich them together with a layer of cream cheese frosting! It was so simple to do! I used a little parchment paper under my bake to make sure it lifted off easily enough, and presto! My Cake Mix Oreo Bars were assembled! You could even use two loaf pans to create the same effect, but I wanted to make sure this sheet pan method worked! It was really easy to place the other half on top without it breaking!
My Homemade Oreo Secrets
Okay, I tell people this all the time. Serve your Homemade Oreos and these Cake Mix Oreo Bars cold! This will keep the frosting from gushing out when you bite into them and plus, they taste way better cold! My second tip would be to not over bake the cookie part. This dough really doesn’t take long to bake and you want it to be on the fudgy side anyway. I got these perfect cuts in my bars because I let them chill for at least 20 minutes! This is a great dessert to make the night before a party because it can hang out in the fridge all night long!
These Cake Mix Oreo Bars are rich! I cut them in these big squares for photos but when I took them to a party I cut them all again to make little rectangles.
The Best Cake Mix Oreo Bars
I haven’t seen anything like these Cake Mix Oreo Bars on pinterest or google so I may be the first to invent, but just watch out because they’ll be popping up at parties from now on. They’re my new go-to treat! They’re quick and easy to make and will steal the show!

Cake Mix Oreo Bars
Ingredients
- OREO BARS:
- 1 box Pillsbury Devil's Food Cake Mix
- 2 eggs
- 1/3 C. oil
- CREAM CHEESE FILLING:
- 6 Tbsp. unsalted butter softened
- 8 oz. cream cheese
- 1 tsp. vanilla extract
- 2-3 C. powdered sugar
Instructions
-
1. Preheat oven to 350 degrees and line baking pan with parchment paper.
-
2. Combine cake mix, eggs and oil. Dough will be thick.
-
3. Press into a 9X13 pan (or use half of a regular sheet pan, the dough won't spread) (or you can use two loaf pans!)
-
4. Bake for 10-15 minutes! These will be fudgy cookie bars!
-
5. Let cool in pan.
-
6. Filling: Beat butter and cream cheese until smooth. Add vanilla extract and 2 cups powdered sugar. Continue to add sugar until you reach your desired sweetness. Remember that the chocolate layers will be sweet so the filling can be less sweet to balance it out.
-
7. If you baked your dough on one pan, cut the bake in half and frost one on the halves. Then place the other side of the bake on top to sandwich the two together with your layer of cream cheese filling in the middle.
-
8. Let chill in the fridge for at least 20 minutes and then cut into bars. These are very rich, so I recommend small slices! I also recommend serving them cold!
I want one, right now!!
Something is very wrong with this recipe. I had to throw it out. Cooking for only 6 minutes left the thick chocolate cake raw in a 9×13 pan. I added another ten minutes, but cake was still wet. Also, I lined with parchment, and the cake stuck to the paper. I won’t make this again, but if others do, line with nonstick foil or spray the parchment.
I have made this cake several times with no issue! I’m so sorry you had problems. It sounds like you were using WAX paper and not parchment paper, you NEVER want to bake with wax paper! Parchment paper never sticks to anything! Also, do take the recommendation in the recipe to use a Pillsbury Cake mix! The cookie bars are supposed to be fudgy and not like a fluffy cake!
I have been making this for almost 30 yrs. Only difference is I made them into cookie size balls them put the icing in the middle. I gave used Betty Crocker cake mix and Duncan Hines. Never an issue. Works pretty good for ice cream sandwiches too.
This is a very old recipe, at least 20 years. We would make these into cookies instead of a bar. Can switch up the cake mix to different flavors also.
I just love to eat Oreo bars. It looks really delicious with cake.
Thanks for sharing the recipe.

Wow this cake recipe is so good thank you for sharing your recipe
The “cook time” and “total time” are wrong on the recipe card. I have not made this but I make another quick cookie bar recipe with the same ingredients and it has to cook AT LEAST 20 minutes to be done… not fluffy, just not raw(EGGS!). Also, you suggest various pan sizes which would dramatically change the cook time required but you don’t make any suggestions on those adjustments. This looks good… but the directions require some work to ensure success.
Can they be frozen?
What a recipe. seems to be very delicious
amazing oreo cake and good style of recipe, liked it very much.
amazing cake and nice receipe thanks for sharing with us
nice CAKE receipe thanks for sharing with us
This is the closest thing I’ve ever found to the “Panda Brownies” a local restaurant sells. The only difference is that bar is topped with chocolate frosting. Yeah!
Can you use salted butter?
Please tell me the exact dimensions of the sheet cake pan. I want to make them, but a 9 X 13 pan is too small. Thank you
Use an 10 by 15 cookie sheet it’s a perfect size
This looks so good! This would be a fun one to make with kids!
Thanks for sharing! Does it keep long?
Trying this out tonight last minute dessert idea. You refer to cake mix and cookie mix – saying it won’t spread as it’s a cookie mix. Umm it’s a cake mix. I’m using a dunkerin gf cake mix. The one end is a little messed up that’s in the middle of the pan. It’s a little lopsided as I probably tipped it as I was putting it in the oven. Just waiting for it to cool now. Fingers crossed I can save it. I’ve taste tested the icing while waiting – it’s great but mine is less white than yours.
Very easy to follow . And it’s delicious no problems ever making them . Thanks for sharing I’ve also did them as sandwich cookies and holidays and crops coloring for the cream cheese. Always a big hit.
Unfortunately, I was not a fan. They were simple enough to make, but underwhelming in flavor. I had hoped to make these for a bake sale. And although I followed the recipe precisely, they were dry too dry to offer for sale.
Love this recipe! Made it today and my family really loved it! I used a glass pan and sprayed it instead of using parchment.
Followed the recipe but my filling was runny. When I make them again, I will leave out the butter and add some coconut.
I love oreo bars. I will definitely try it a home.
I had a box of Devil’s Food cake mix on hand so I decided to try making these. So easy and a huge hit! I love that I could eat one small piece and feel completely satisfied. Thanks for the awesome recipe that I will definitely make again!
Soo beautiful oreo bars. My children want to eat them. Will you make this for them also?
Delicious! The whole family loved it. Will definitely make again and double the batch next time!!
Made these super good looking oreo bars for the desert last night and have to say what a delicious outcome it had. My family couldn’t believe that it was made by me. Thanks for sharing the recipe. Keep up the good work.

I didn’t have a 13 x 9 available, so I used a regular cookie sheet and just spread the dough in the middle into a square. Baked perfectly in 12 minutes. Did not stick to parchment! The icing was delish! After I refrigerated it for about an hour, my daughter helped herself and said it was amazing!
Love it!

Wow this cake recipe is so good thank you for sharing your recipe…
Something is definitely wrong with the filling. I followed instructions to a T and the filling was sooo runny. When I cut them, they oozed out and looked terrible. Unfortunately I made them for a funeral and was embarrassed to take them.

I saw a recipe for Bars. There’s four ingredients in it I devil’s food cake mix, milk , instant pudding and Heath bits. When I found the recipe my daughter was at the grocery store so I called her and asked her to bring home the heath bits. I went back to the recipe and it was gone. I’m looking for the amount of milk and instant pudding and what kind of instant pudding. If anyone can help me I thank you immensely.
Very informative

Very nice recipe
This tastes absolutely delicious. However, some technical issues with the recipe:
–as others have commented, the filling is MUCH TOO RUNNY, even when chilled. Honestly they probably need to be frozen to have any chance of cutting them nicely.
–making these into sandwiches is very rich. You end up with a huge glob of icing in the middle and really thick cake slices on top/bottom.
Instead of making sandwiches, I just baked the cookie/cake as directed, spread the icing over the top, and cut them into individual bars. It’s still gooey and oozey, but at least you don’t have the issue of icing gooshing out from the middle when you bite into it.
I haven’t made this yet but could I use cupcake pan
I simply love eating Oreo bars. It looks delicious when paired with cake.Thanks for sharing this recipe.

Just made these with no issues. Used Duncan Hines devil’s food cake and followed the recipe provided. Cake was fudgy not dry and filling was perfect consistency. Will definitely make these again!
Forgot to rate in first comment:)
I also use Pilsburry mix as well , it is pretty standard product .
First, the prep time is way off. It takes about 15 minutes to work the dough into the pan to spread it out. Very frustrating and time consuming. No matter how good they are…sorry, they aren’t worth the effort and I won’t make them again. 🙁
Amazing recipe! I will deifinately try this recipe.
