Cookies and Cream Brownies Ingredients
For the Brownies
• Unsalted Butter – Provides richness and moisture; substitute with margarine for a dairy-free option.
• White Chocolate Chips – Adds sweetness and creaminess; can be replaced with semi-sweet chocolate chips for a less sweet version.
• Large Egg – Binds the ingredients together; a flax egg (1 tbsp ground flaxseed + 2.5 tbsp water) works for a vegan option.
• Sweetened Condensed Milk – Contributes to the fudgy texture; no direct substitution, but you can use less for a lower sweetness.
• Salt – Enhances flavors; can be reduced or omitted based on dietary needs.
• All-Purpose Flour – Provides structure; substitute with gluten-free flour for a gluten-free version.
• Oreos (crushed) – Adds crunch and chocolate flavor; any chocolate sandwich cookie can be used for variety.

Step‑by‑Step Instructions for Cookies and Cream Brownies
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). While the oven warms up, grab an 8″x8″ baking pan and line it with parchment paper, allowing some overhang for easy removal later. This step sets the stage for perfectly baked fudgy Cookies and Cream Brownies, ensuring they cook evenly.
Step 2: Melt the Butter and Chocolate
In a large microwave-safe bowl, combine the unsalted butter and white chocolate chips. Microwave for 30 seconds, then stir. Continue heating in 15-second intervals, stirring in between until the mixture is completely melted and smooth, which should take about 1-2 minutes total. This luscious mixture forms the base of your brownies.
Step 3: Add the Wet Ingredients
Once the butter and chocolate are melted, add the large egg, sweetened condensed milk, and a pinch of salt to the bowl. Whisk these ingredients together until they are fully combined and glossy, creating a rich, creamy batter. This adds moisture and a fudgy texture that makes these Cookies and Cream Brownies irresistible.
Step 4: Incorporate the Dry Ingredients
Sprinkle the all-purpose flour over the wet mixture and gently fold it in using a spatula. Be careful not to overmix; you want just enough flour incorporated to create a thick batter. This will help retain the ultra-fudgy texture of your brownies while combining the delicious flavors of the cookies and cream.
Step 5: Mix in the Oreos
Take 5 crushed Oreos and fold them into the brownie batter gently. This adds delightful chunks of chocolate and a nice crunch to your Cookies and Cream Brownies. Make sure the Oreo pieces are evenly distributed throughout the batter, enhancing the flavor in every bite.
Step 6: Prepare for Baking
Pour the fudgy batter into your prepared baking pan, smoothing the top with a spatula to create a level surface. To amp up the Oreo goodness, sprinkle the remaining 2 whole crushed Oreos over the top, pressing them in lightly to ensure they stick during baking. This adds a fantastic finish to your brownies.
Step 7: Bake the Brownies
Place the pan in your preheated oven and bake for 30-35 minutes. You’ll know your Cookies and Cream Brownies are done when the surface is light brown, and a toothpick inserted into the center comes out with a few moist crumbs rather than wet batter. This ensures that fudgy consistency you desire.
Step 8: Cool and Cut
Once baked, remove the brownies from the oven and allow them to cool in the pan for at least one hour. This cooling time is crucial for the brownies to set properly and prevents them from crumbling when you cut them. Once cool, use the parchment overhang to lift the brownies out and cut them into squares to serve.

Make Ahead Options
These Cookies and Cream Brownies are perfect for meal prep, allowing you to enjoy a delicious treat without the fuss on busy days! You can prepare the batter up to 24 hours in advance; simply cover the bowl with plastic wrap and refrigerate to keep it fresh. When you’re ready to bake, just pour the cold batter into the prepared baking pan and bake as instructed. For longer storage, bake the brownies and let them cool completely before cutting. Store the cut squares in an airtight container at room temperature for up to 3 days or refrigerate for up to a week to maintain their fudgy goodness. With these make-ahead tips, you’ll savor these delightful Cookies and Cream Brownies anytime with minimal effort!

Cookies and Cream Brownies Recipe FAQs
What type of Oreos should I use for the brownies?
Absolutely! I recommend using classic Oreos for this recipe, as their chocolate flavor blends perfectly with the fudgy brownies. However, feel free to get creative! You can substitute them with any chocolate sandwich cookie, like Double Stuf Oreos for extra creaminess or even flavored varieties to put a unique spin on your dessert.
How should I store leftover brownies?
For optimal freshness, store your Cookies and Cream Brownies in an airtight container at room temperature for up to 3 days. If you want to keep them for longer, place them in the refrigerator, where they can last up to a week. This keeps them moist and fudgy!
Can I freeze Cookies and Cream Brownies?
Yes, you can definitely freeze these brownies! Wrap each cut piece tightly in foil or plastic wrap, then place them in an airtight container or freezer bag. They will stay delicious for up to 3 months. When you’re ready to enjoy them, thaw in the fridge overnight, or warm them in the microwave for about 10-15 seconds for that fresh-baked fudgy experience.
What can I do if my brownies turn out too cakey?
If your brownies turn out cakey, it’s likely because they were overbaked. To achieve that ultra-fudgy texture, always check for doneness by inserting a toothpick; it should come out with a few moist crumbs, not completely clean. Next time, consider reducing the baking time by a couple of minutes and keep a close eye on them as they bake, ensuring you catch that ideal gooey consistency.
Is there a vegan option for this recipe?
Absolutely! You can easily make these Cookies and Cream Brownies vegan by substituting the large egg with a flax egg. To create this, combine 1 tablespoon of ground flaxseed with 2.5 tablespoons of water and let it sit for a few minutes to thicken before adding it to the batter. Swap the unsalted butter for margarine, and you’re on your way to a deliciously fudgy vegan treat!
