Cookies and Cream Brownies Ingredients
• Here’s what you’ll need to create these mouthwatering brownies!
For the Brownie Base
- Unsalted Butter – Base fat for moisture and richness; substitute with margarine if necessary.
- White Chocolate Chips – Provides sweetness and richness; can be swapped with milk chocolate chips for a deeper flavor.
- Large Egg – Acts as a binder for structure; a flax egg can replace it for a vegan version.
- Sweetened Condensed Milk – Adds sweetness and moisture, ensuring a fudgy texture; essential for the cookies and cream flavor profile.
- Salt – Enhances the overall flavor; optional to omit.
- All-Purpose Flour – Provides structure to the brownies; substitute with gluten-free flour for a gluten-free option.
For the Cookies and Cream Flavor
- Oreos (crushed) – Adds that iconic cookies and cream flavor; use different flavored Oreos for a fun twist.
- Additional Crushed Oreos (for topping) – Sprinkled on top for an extra crunch and flavor boost; can add chocolate drizzle for decadence.
Step‑by‑Step Instructions for Cookies and Cream Brownies
Step 1: Preheat Oven
Start by preheating your oven to 350°F (175°C). While waiting, line an 8″x8″ baking pan with parchment paper, allowing some overhang for easy removal later. This preparation ensures your Cookies and Cream Brownies have the perfect crust and are ready for baking as soon as you’ve mixed your batter.
Step 2: Melt Butter and Chocolate
In a microwave-safe bowl, combine unsalted butter and white chocolate chips. Heat the mixture in the microwave in 30-second intervals, stirring after each, until it’s smooth and fully melted—about 1-2 minutes total. This step creates a luscious base for your fudgy brownies, rich in flavor and sweetness.
Step 3: Mix Wet Ingredients
Allow the melted mixture to cool for a moment before whisking in one large egg, sweetened condensed milk, and a pinch of salt. Blend these ingredients until smooth and well combined, creating a creamy mixture. This will help ensure a delightful fudginess throughout your Cookies and Cream Brownies.
Step 4: Incorporate Dry Ingredients
Gently fold in the all-purpose flour until just combined, being careful not to overmix. You’ll want to see a few flour streaks remaining as you mix. This step is crucial to maintaining the tender texture of your brownies, giving them that melt-in-your-mouth quality you love.
Step 5: Add Crushed Oreos
Now it’s time to introduce the star of the show! Gently stir in five crushed Oreos into the brownie batter, ensuring they’re evenly distributed. This adds that iconic cookies and cream flavor and delightful bites of texture throughout your mixture, elevating your Cookies and Cream Brownies to the next level.
Step 6: Top with More Oreos
Pour the brownie batter into the prepared pan and smooth it evenly. Then, scatter the remaining crushed Oreos on top, pressing them gently into the batter. These chunks will create a tasty topping that gets slightly crisp while baking, making your brownies even more irresistible.
Step 7: Bake
Place your brownie-filled pan into the preheated oven and bake for 30-35 minutes. To check for doneness, insert a toothpick into the center; it should come out with a few moist crumbs but not wet batter. Baking them just right ensures your Cookies and Cream Brownies maintain that fudgy center.
Step 8: Cool and Cut
Once baked to perfection, remove the pan from the oven and let it cool for at least 1 hour. This cooling period allows the brownies to set properly. Once cool, carefully lift them out using the parchment paper and cut them into squares for serving, revealing the delightful goodies inside.

Make Ahead Options
These Cookies and Cream Brownies are a fantastic choice for meal prep enthusiasts! You can prepare the brownie batter up to 24 hours in advance by mixing all the ingredients as instructed and storing it in an airtight container in your refrigerator. This not only saves time but ensures you have a fresh, fudgy treat whenever you’re ready to bake. When it’s time to cook, simply pour the chilled batter into the lined baking pan, top with crushed Oreos, and bake as directed. For optimal freshness, avoid refrigerating the baked brownies, as they are best enjoyed within 3 days at room temperature, maintaining their delicious texture and flavor.
How to Store and Freeze Cookies and Cream Brownies
Room Temperature: Store your Cookies and Cream Brownies in an airtight container at room temperature for up to 3 days to maintain their wonderful fudgy texture.
Fridge: If you prefer firmer brownies, refrigerate them in an airtight container. They’ll last up to 5 days, providing even more decadence with a chilled treat.
Freezer: For longer storage, freeze the brownies. Wrap them tightly in plastic wrap and then in aluminum foil to avoid freezer burn, and enjoy them for up to 3 months.
Reheating: To enjoy a freshly baked feel, reheat individual squares in the microwave for about 10-15 seconds until warm and gooey—pure bliss with each bite!
Expert Tips for Cookies and Cream Brownies

Non-Stick Pan: Use a non-stick pan to prevent any sticking; consider using parchment paper as noted to make removal easier.
Cooling Time: Allow the brownies to cool completely before cutting. This helps them set and ensures clean, even squares—no crumbling!
Storage Savvy: Store your Cookies and Cream Brownies in an airtight container for up to 3 days at room temperature. For longer shelf life, freeze them for up to 3 months.

Cookies and Cream Brownies Recipe FAQs
How should I select my Oreos for the best flavor?
Absolutely! When choosing Oreos, opt for fresh ones without any dark spots, as these can indicate age and staleness. Depending on your preference, you could also experiment with different flavored Oreos like mint or peanut butter for unique twists in your cookies and cream brownies.
How should I store my Cookies and Cream Brownies?
To keep your brownies fresh, store them in an airtight container at room temperature for up to 3 days. If you want a firmer texture, I recommend refrigerating them for up to 5 days. Just be sure to let them come to room temperature for a bit before enjoying to restore some of that melted goodness!
Can I freeze my Cookies and Cream Brownies?
Absolutely! To freeze your brownies, first, allow them to cool completely. Then, wrap the squares tightly in plastic wrap, followed by aluminum foil to prevent freezer burn. They’ll stay fresh for up to 3 months! When you’re ready to indulge, reheat them in the microwave for about 10-15 seconds to revive that fudgy texture.
What should I do if my brownies are too tough?
Very! If you find your cookies and cream brownies are too tough, it might be due to overmixing the batter. Mix just until the flour is incorporated and no more! Additionally, ensure your baking pan is properly greased or lined to prevent sticking, as this can affect your brownies’ texture as well.
Are there any allergy considerations for this recipe?
Definitely! If you or your guests have allergies, keep in mind that Oreos contain gluten and dairy. For a gluten-free option, you could substitute the all-purpose flour with a gluten-free blend. If someone has a dairy allergy, use plant-based butter and a flax egg for a fully vegan modification without sacrificing taste.
