These Oreo bars are a chewy brown sugar blondie base studded with white and semisweet chocolate and plenty of Oreo cookies. They’re quick to make and perfect for sharing.
If you love Oreos, you’ll want to try these cookies-and-cream bars. They’re rich, easy to slice, and ideal for parties or an everyday treat.

I’m a big fan of bar cookies. They take far less time than rolling individual cookies and baking batch after batch, which is handy on busy days or when baking with kids who want results quickly. These Oreo bars are a favorite when I want something simple, fast, and crowd-pleasing.
Bar cookies are great on their own, but they reach the next level when you add Oreos and a mix of white and semisweet chocolate. For other chocolatey treats, try substituting different chips or chopped candy for variety.

Oreo Bars Ingredients
For these Oreo bars you’ll need: all-purpose flour, baking soda, salt, unsalted butter, packed light brown sugar, granulated sugar, an egg, vanilla extract, chopped Oreo cookies, white chocolate chips (or chunks) and semisweet chocolate chips (or chunks).
How Do You Make Oreo Bars?
Preheat the oven and prepare an 8-inch square pan by spraying it and lining it with parchment, leaving an overhang for easy removal. Whisk together the flour, baking soda and salt. In a stand mixer (or using an electric mixer), cream the softened butter with the brown and granulated sugars until light and fluffy. Add the egg and vanilla, mixing until incorporated, then with the mixer on low, add the dry ingredients and mix just until combined.
Fold in half of the chopped Oreos and half of both kinds of chocolate with a spatula. Press the dough into the prepared pan in an even layer, then scatter the remaining Oreo pieces and chocolate on top. Bake until a toothpick inserted in the center comes out with a few moist crumbs—about 20–25 minutes (glass pans may need a few extra minutes). Let cool completely in the pan, use the parchment overhang to lift the slab out, and cut into squares to serve.

Tips For The Perfect Oreo Bars
- Use chocolate chips or chunks depending on the texture you prefer; a mix of both adds visual appeal and varied bites.
- Chop the Oreos into uniform, bite-sized pieces for even distribution.
- Choose white chocolate made with cocoa butter rather than palm oil for a cleaner flavor and better texture.
- When folding in the cookies, keep the pieces intact—avoid breaking them into powder.
Quick Tip
A stand mixer makes the job easiest, but any electric mixer will work fine.

Flavor Variations
This base is flexible—try different combinations to match your taste:
- Cookies: Swap in seasonal Oreo flavors or Double Stuf. Other favorite sandwich cookies can be chopped and used instead.
- Candies: Replace some chocolate chips with M&Ms or small chocolate candies for color and crunch.
- Marshmallows: Mini marshmallows add a chewy contrast when folded in.
- Nuts: Add chopped pecans, walnuts, or almonds for texture and a toasty flavor.
These bars are a hit with both kids and adults. Serve them as small squares after a meal or as a rich afternoon snack—either way, they disappear fast.
