Oreo Blondies
This post contains affiliate links. Read the full disclosure here.
These gooey, thick and chewy Oreo blondies are loaded with Oreo pieces and chocolate chips! They’re so easy to make, plus they’re made in one bowl with no mixer required. I’ve tested this recipe with regular dairy ingredients as well as dairy free to make sure that it works both ways!
I am such a big believer that almost everything tastes better with Oreos, so I decided to take my classic blondie recipe and turn it into yet another insanely delicious Oreo dessert.
These Oreo blondies have a perfect crinkly top and are perfectly gooey on the inside. Inspired by my Oreo brownies, every bite has Oreo cookies and chocolate chips in it. What could be better?

These blondies are easy to customize, and you can add white chocolate chips, seasonal add-ins, or even different flavors of Oreo cookies. Everyone who I’ve made them for has gone back for seconds and absolutely loved them!
They don’t require any leavener (baking soda or baking powder) which is partly what helps us achieve the brownie-like texture, instead of being cakey. You just need a few very simple pantry staples to whip up this recipe!
Ingredient Notes
- Butter: you can use regular butter or dairy free butter. When testing this recipe, I preferred salted because I like my desserts less sweet.
- Oreos: I’ve tested this recipe with regular Oreos, but you can also use double stuf Oreos or different flavored Oreos!
How To Make These Blondies
Combine all wet ingredients.
Add in flour and salt.
Stir in chocolate chips and Oreos!
Bake!
Recipe Developer Expert Tips
- When making blondies with Oreos in them, don’t be tempted to mix the batter too much either before or after adding the Oreos. This can affect the texture of the blondies.
- These blondies are meant to be gooey. They are not meant to be cakey (or dry), otherwise you have over-baked them! Be sure to start doing the toothpick test early to avoid overbaking.

Ingredients
- ¾ cup (158 g) butter, melted, (regular or vegan)
- 1 cup (200 g) light brown sugar
- ½ cup (100 g) granulated sugar
- 2 eggs
- 1 Tablespoon vanilla extract
- ½ teaspoon salt
- 1¾ cup (220 g) all-purpose flour
- ½ cup (90 g) semisweet chocolate chips
- 14 Oreo cookies, chopped, (plus 1-2 more for topping if desired)
Instructions
- Preheat your oven to 350°Fahrenheit and line an 8×8 baking pan with parchment paper.
- Melt the butter in a microwave safe bowl, then add the light brown sugar and granulated sugar to the melted butter. Whisk until it forms almost a paste and starts to pull away from the sides of the bowl.
- Add the egg and vanilla extract and whisk until combined.
- Add the flour and salt, gently stir until the dry ingredients have just combined.
- Stir in the chopped Oreos and chocolate chips.
- Pour the blondie batter into your prepared pan. If you want you can sprinkle extra chocolate chips and Oreo cookies on top.
- Bake the Oreo blondies for 25-35 minutes. A toothpick inserted should come out with a few wet crumbs, but no batter (not completely clean)! Let the blondies cool completely in the pan before slicing.

Notes
The calorie information provided for this recipe is an estimate. The accuracy of the calories listed is not guaranteed.
Is the butter unsalted?
You can use either, if you prefer a sweeter brownie, use unsalted. I personally like desserts to be on the slightly less sweet side so I often am fine with salted butter. Either is fine though based on your personal preference.
how long to bake it in the 8 by 9?
You wont need as long as the 8×8 pan, so I would start checking around 20 minutes. I’d say it could take anywhere from 20-30 minutes depending on your oven.
Are you able to make a larger batch in a 13×9 pan? Double the recipe?
Yes definitely!
You mention a preference for weighing flour (and I do like to do that) but you did not include a weight for the flour. I have noticed some differences in what some think a cup weighs. What weight do you use? Thanks!
You can find metric measurements to weigh the flour on the recipe card, just click the metric tab next to the Ingredients heading and it’ll switch to grams from US customary!
allll your blondies recipes are to die for!! these were sooo good as an oreo and chocolate lover 😀 AMAZING.
So happy to hear this! Thank you for your review🩵
Any recipe adjustments if using a 9×9 pan?
Nope, the blondies will just be a bit less thick!
These are so delicious, I made them twice over a week and they go in no time!! I have reduced the total sugar by 50 grams and they are still sweet and moreish. I am going to try these using M&Ms just like someone said 🙂
Thank you so much for your review Sam!
Made it for a Christmas party and it was such a hit!!
I’ve made these three times and every single time, everyone asks for more!!! I use pre-crumbled Oreo pieces and I put…a whole lot lol!! Thank you for this recipe!
Thank you so much for your review! So glad to hear these blondies are a hit!
Can I freeze the blondies batter till whenever I want to use it ???
Hi Suraiya! I have never tried freezing blondie batter so I really can’t say for sure!
Hi! What are the directions for doubling the recipe?
Hi Isabel! You can easily convert the measurements to double by heading to the recipe box, then next to the heading “Ingredients” you’ll see boxes for “US Customary”, “Metric”, “1x”, “2x”, and “3x”. Click the “2x” box and that will give you a recipe for double the measurements.
I’ve made these multiple times and they’re always a hit! For the holidays I added Xmas colored m&ms and it was a great addition! Highly recommend these!
Hi Rebecca! Thanks so much for your review 😊 Love the addition of holiday m&ms – fantastic idea!
I tried this recipe and replaced Oreo with Lotus Biscoff !!! Still successfully made and taste great 👍🏻
Love that idea Jessica! I’m so happy you loved the recipe, thank you for the review!
These are absolutely fantastic and such a crowd pleaser!
I love Oreos and found this recipe when looking for a way to incorporate them into my baking. These blondies are so flavourful and the perfect texture. Soft and rich on the inside with a chewy outside. The recipe was also really easy to follow and pretty quick to whip up.
I added a combination of bittersweet and white chocolate chips. Highly recommend this recipe, I will definitely be making these again for my friends and family!
Yay! I’m so happy the blondies were a success! Thanks so much for the review!
You mentioned they can be easily made vegan. Could you please tell us how to
Hi! These can’t be made vegan, they can be made dairy free by using vegan butter and chocolate chips. I haven’t tested them with egg substitutes.
Can the recipe be cut in half?
Yes, you can use an 8×4 or 9×5 loaf pan!
