How to Make Cookies and Cream Cookie Bars
Preheat the oven to 350°F (175°C). Line an 8×8-inch baking pan with parchment paper.
Step One: In a large bowl, whisk together the flour, sugar, brown sugar, cocoa powder, baking soda, and salt. Add the egg, vanilla, and softened or melted butter. Mix until the batter is smooth and combined.
Step Two: Fold in the chopped Oreos and half of the white chocolate chips. Reserve the remaining chips to sprinkle on top.
Step Three: Spread about two-thirds of the batter evenly into the prepared pan.
Step Four: Arrange whole Oreos on top of the batter, then drop small spoonfuls of the remaining batter between the cookies to partially cover them.
Step Five: Sprinkle the reserved white chocolate chips over the top.
Step Six: Bake for 18–22 minutes, until the bars are just set. They will continue to firm up as they cool. If desired, melt an extra 1/4 cup white chocolate chips with a touch of coconut oil and drizzle over the cooled bars.
Top Tip
For evenly chopped Oreo crumbs, pulse the cookies briefly in a food processor. Be careful not to over-process — you want small pieces, not a fine powder.
Substitutions
- Chocolate chips – Swap white chocolate chips for semi-sweet, milk, or dark chocolate chips to change the flavor profile.
- Cookies – Use a different sandwich cookie or crushed chocolate chip cookies if you prefer a different mix-in.
Variations
- Peanut butter: Dollop a spoonful of peanut butter on top of the batter before adding whole cookies for a peanut-butter twist.
- Extra chocolate: Scatter chunks of milk or dark chocolate on top in place of or in addition to the white chocolate chips.
Equipment
You’ll need an 8×8-inch baking pan, a large mixing bowl (or stand mixer), spatula, and parchment paper.
Storage
Store leftover bars in an airtight container at room temperature or in the refrigerator. They also freeze well — wrap pieces individually or place layers between parchment paper in a freezer-safe container.
Common Questions
The bars should be just set in the center and may still look slightly soft. They firm up as they cool, so avoid overbaking to keep them chewy.
Extra Oreos can be stored in an airtight bag or used in other desserts. They’re great on their own with milk or added to ice cream or brownies.
Yes — sprinkles, nuts, shredded coconut, or extra chocolate are all tasty additions. Customize to your preference.
