Step‑by‑Step Instructions for Halloween Oreo Stuffed Brownies
Step 1: Preheat the Oven
Start by preheating your oven to 350°F (175°C). This ensures that your Halloween Oreo Stuffed Brownies cook evenly and develop that perfect fudgy texture. While the oven is warming up, prepare your baking pan by lining an 8x8 inch dish with parchment paper, leaving a bit of paper hanging over the edges for easy removal later.
Step 2: Melt the Mixture
In a microwave-safe bowl, combine the butter and vegetable oil with the granulated and brown sugars. Microwave this mixture in 30-second intervals, stirring well in between to create a smooth and creamy texture. After about 1 to 1.5 minutes, the ingredients should blend perfectly, leaving no chunky bits of sugar.
Step 3: Whisk in the Eggs
Let the melted mixture cool for a couple of minutes until it's just warm to the touch. Crack the eggs into the bowl one at a time, whisking vigorously after each addition to ensure thorough incorporation. Then, stir in the vanilla extract, which will elevate the heavenly aroma of your Halloween Oreo Stuffed Brownies.
Step 4: Combine Dry Ingredients
Next, gently fold in the all-purpose flour, cocoa powder, and salt until the batter is smooth and no dry flour remains. Be careful not to overmix at this stage; a few lumps are perfectly fine. This step is essential to keep the brownies soft and fudgy!
Step 5: Layer the Brownie Batter
Pour half of the brownie batter into the prepared baking pan, spreading it evenly across the bottom. This serves as the luscious base for your brownies. Use a spatula for a smooth finish; the batter should fill the pan nicely and be visually appealing.
Step 6: Add the Oreo Cookies
Now it’s time to add some fun! Arrange the Oreo cookies evenly over the brownie layer. You can use Halloween-themed Oreos for an extra festive touch. Once positioned, cover the cookies with the remaining brownie batter, ensuring they’re fully encapsulated for that delightful surprise in each bite.
Step 7: Bake the Brownies
Pop the pan into your preheated oven and bake for about 30 minutes. Keep an eye on them as the edges should be firm and the center slightly soft. A toothpick inserted into the middle should come out mostly clean, ensuring your Halloween Oreo Stuffed Brownies are perfectly baked.
Step 8: Cool and Serve
Once done, take the brownies out of the oven and allow them to cool completely in the pan. This will take about 15-20 minutes. With the parchment paper overhang, lift the brownies out and cut them into squares. Enjoy the rich chocolaty layers adorned with creamy Oreo goodness!
Make Ahead Options
These Halloween Oreo Stuffed Brownies are perfect for meal prep, allowing you to enjoy deliciousness with minimal effort on busy nights! You can prepare the brownie batter up to 24 hours in advance; simply refrigerate it in an airtight container to maintain its rich flavor and moisture. If you prefer, you can also layer the batter and Oreo cookies in the pan a day ahead, covering it tightly with plastic wrap. When you’re ready to bake, just remove it from the fridge, and allow it to sit at room temperature for about 30 minutes before popping it into the oven. This way, you’ll achieve that unforgettable fudgy texture just as if you had made them fresh!
Tips for the Best Halloween Oreo Stuffed Brownies

-
Check doneness carefully: Insert a toothpick into the center of the brownies. If it comes out with a few moist crumbs, they’re perfect—undercooked brownies are better than overbaked ones!

Halloween Oreo Stuffed Brownies Recipe FAQs
How do I choose the right Oreos for these brownies?
Absolutely! For a fun twist, I recommend using Halloween-themed Oreos, as they add a festive touch to your brownies. However, classic Oreos work just as deliciously. Just ensure they are fresh and not expired for the best flavor.
How should I store leftover brownies?
To keep your Halloween Oreo Stuffed Brownies fresh, store them in an airtight container at room temperature for up to 3 days. If you want to extend their shelf life, you can refrigerate them for up to a week. Make sure they are tightly covered to prevent them from drying out.
Can I freeze these brownies? If so, how?
Yes, you can absolutely freeze your Halloween Oreo Stuffed Brownies! To do this, individually wrap each brownie square in plastic wrap and place them in a freezer-safe bag. They will stay fresh for up to 3 months. When you're ready to indulge, simply thaw them in the fridge overnight and warm them briefly in the microwave to bring back that delightful moisture.
What if my brownies come out too cakey?
Very! If your brownies turn out too cakey, it might be due to overmixing the batter or baking them too long. To maintain that fudgy texture, mix until just combined, and check for doneness around the 25-minute mark with a toothpick—it should come out with a few moist crumbs, not clean.
Are these brownies safe for kids and those with allergies?
The Halloween Oreo Stuffed Brownies do contain eggs, dairy, and gluten, so they may not be suitable for anyone with allergies to these ingredients. If you're baking for individuals with dietary restrictions, consider using gluten-free flour or egg substitutes (like applesauce) for a modified version. Always double-check packaging for allergy information, especially with the Oreos!
