Step‑by‑Step Instructions for Cookies and Cream Brownies
Step 1: Preheat the Oven and Prepare the Pan
Begin by preheating your oven to 350°F (175°C). While it heats, take an 8″x8″ baking pan and line it with parchment paper, allowing some overhang for easy removal later. This preparation ensures your ultra fudgy cookies and cream brownies will release effortlessly after baking, giving you a smooth finish to your dessert.
Step 2: Melt Butter and White Chocolate
In a microwave-safe bowl, combine the softened unsalted butter and white chocolate chips. Microwave in 20-second intervals, stirring in between, until melted and smooth. This process should take about 1-2 minutes total. The mixture should appear glossy without any visible chocolate chunks, setting the stage for the rich base of your brownies.
Step 3: Combine Wet Ingredients
Once the chocolate mixture is smooth, add one large egg, sweetened condensed milk, and a pinch of salt. Using a whisk or a spatula, stir vigorously for 1-2 minutes until fully combined and slightly thickened. This creates a luscious blend that forms the foundation of your cookies and cream brownies, ensuring a beautifully fudgy texture.
Step 4: Fold in the Flour
Gradually sift in all-purpose flour, folding it gently using a spatula. Mix just until the flour disappears into the batter, being careful not to overmix—this helps maintain the ultra fudgy texture. The batter will become thick and glossy, indicating that it’s ready for the next step in crafting your delectable brownies.
Step 5: Add Crushed Oreos to the Batter
Gently fold in 5 crushed Oreos into the brownie batter to evenly distribute the cookies and cream flavor throughout. Ensure the pieces are mixed well but still chunky enough to provide texture. This will enhance the rich, chocolatey taste of your cookies and cream brownies, adding delightful bits of Oreo in every bite.
Step 6: Pour the Batter into the Pan
Transfer the brownie batter into your prepared baking pan, spreading it evenly with a spatula. Make sure to smooth the top, allowing for even baking. As you pour, admire the rich, dense batter filled with Oreo pieces, which promises a fudgy treat once baked.
Step 7: Sprinkle Extra Oreos on Top
Take the remaining crushed Oreos and sprinkle them generously over the top of the brownie batter. This not only adds an appealing visual layer but also gives your cookies and cream brownies an extra crunch. The contrast between the chewy brownies and crunchy toppings will be an absolute delight.
Step 8: Bake the Brownies
Slide the pan into your preheated oven and bake for 30-35 minutes. Keep an eye on them, and check for doneness by inserting a toothpick in the center; it should come out with a few moist crumbs but not wet batter. The top should be set but slightly gooey when lightly pressed—a perfect sign of ultra fudginess.
Step 9: Cool Before Slicing
Once baked, remove the brownies from the oven and allow them to cool in the pan at room temperature for at least 1 hour. This cooling period is crucial, as it will help the brownies set, making them easier to slice into perfect squares. Patience pays off, ensuring each piece is decadent and beautifully fudgy!
Step 10: Slice and Serve
Finally, lift the brownies out of the pan using the parchment paper overhang, and place them on a cutting board. With a sharp knife, slice them into squares, revealing the rich layers and crumbles of Oreo. Serve them warm or at room temperature—these cookies and cream brownies are a treat sure to impress family and friends alike!

How to Store and Freeze Cookies and Cream Brownies
Room Temperature: Keep your brownies in an airtight container at room temperature for up to 3 days. This will keep them deliciously moist and chewy.
Fridge: If you want to extend their shelf life, store them in the fridge for up to 1 week. Ensure they’re covered tightly to prevent drying out.
Freezer: For longer storage, freeze brownies by wrapping them individually in plastic wrap and placing them in a freezer-safe bag. They can last up to 3 months, ready for your indulgent cravings!
Reheating: To enjoy your frozen cookies and cream brownies, let them thaw at room temperature for about 30 minutes or warm them briefly in the microwave for that freshly baked feel.
Make Ahead Options
These ultra fudgy Cookies and Cream Brownies are perfect for busy home cooks looking to save time without sacrificing flavor! You can prepare the brownie batter up to 24 hours in advance; simply mix everything, then cover it tightly and refrigerate. To maintain the best quality, gently re-mix the batter before spreading it into the pan and topping with crushed Oreos. Alternatively, bake the brownies and allow them to cool before storing in an airtight container for up to 3 days at room temperature or 1 week in the refrigerator. When ready to serve, simply slice and enjoy! This prep-ahead approach saves you valuable time while keeping your desserts deliciously fresh.

Cookies and Cream Brownies Recipe FAQs
What is the best way to select Oreos for this recipe?
Absolutely! When choosing Oreos, look for cookies that are fresh and intact without any dark spots or cracks on the packaging. The fresher the cookies, the better the flavor and texture in your brownies. If you’re feeling adventurous, you can also try different flavored Oreos to give your brownies a unique twist!
How should I store the cookies and cream brownies after baking?
You can keep these delectable brownies in an airtight container at room temperature for up to 3 days, ensuring they remain fluffy and moist. If you want them to last longer, pop them in the fridge for up to a week. Just remember to cover them tightly to prevent drying out, which can happen in cooler environments.
Can I freeze cookies and cream brownies?
Yes, indeed! To freeze, first let your brownies cool completely, then wrap them individually in plastic wrap to preserve their fudgy texture.

What can I do if my brownies are too gooey in the center?
If your brownies turn out too gooey, it could be due to underbaking. Next time, be sure to check them at the 30-minute mark by inserting a toothpick; it should come out with a few moist crumbs.

Very much so! Feel free to experiment with different types of chocolate chips.
