Ingredients for Halloween Oreo Stuffed Brownies
Okay, let’s talk ingredients – the real magic behind these brownies! I’ve made this recipe enough times to know exactly what works (and what doesn’t). Trust me, these measurements matter – especially those cold eggs we’ll chat about later. Here’s everything you’ll need lined up on your counter:
Wet Ingredients
- ⅔ cup butter (melted – I just zap it in the microwave in 20-second bursts so it doesn’t splatter everywhere)
- ¼ cup vegetable oil (this is my secret for extra fudgy texture – don’t skip it!)
- 1 cup granulated sugar
- ⅓ cup packed brown sugar (pack it tight in your measuring cup for that caramel depth)
- 2 large eggs, cold right from the fridge (yes, cold – we’ll talk about why this matters in the tips section!)
- 1 teaspoon vanilla extract (the good stuff – it makes a difference)
Dry Ingredients
- ⅔ cup cocoa powder (I use Dutch-processed because I’m fancy like that)
- ½ teaspoon salt (balances all that sweetness perfectly)
- ½ cup all-purpose flour (measured by spooning into the cup, not scooping – we want light and fluffy here)
The Star of the Show
- 15 whole Halloween Oreos (those orange creme centers make them extra festive)
- 5 extra Oreos, crushed (for that perfect crunchy topping – kids love helping with this part!)
See? Nothing too crazy – just good, simple ingredients that come together to make something magical. Now let’s get mixing!
How to Make Halloween Oreo Stuffed Brownies
Alright, let’s get baking! I promise this process is as fun as it is easy. Just follow these steps, and you’ll have the most incredible Halloween Oreo stuffed brownies ready before you can say “trick or treat!”
Step 1: Melt Butter and Sugars
First things first – preheat that oven to 350°F and line your 8×8-inch pan with parchment paper (trust me, you’ll thank me later when these beauties slide right out). Now for the magic:
Grab a microwave-safe bowl and toss in your butter, oil, and both sugars. Microwave in 30-second bursts, stirring between each one. After about 90 seconds total, give it one last minute-long zap and then whisk like crazy! You want that sugar fully dissolved – it should look glossy and smooth. Pro tip: If you’ve got a hand mixer, now’s the time to use it – the extra beating helps create that perfect fudgy texture.
Step 2: Combine Wet and Dry Ingredients
Time to bring everything together! Whisk in those cold eggs one at a time (yes, cold – it prevents greasiness), then add the vanilla. The batter will pull away from the sides slightly – that’s exactly what we want!
Now, gently fold in your flour, cocoa powder, and salt. I mean GENTLY – no vigorous stirring here! We’re making brownies, not bread. Stop when you just barely see no more flour streaks. Overmixing = tough brownies, and nobody wants that.
Step 3: Layer and Bake
Here comes the fun part! Pour half the batter into your prepared pan and spread it evenly. Now carefully place those 15 whole Oreos in a single layer – try to space them evenly so every brownie gets cookie goodness!
Dollop the remaining batter over the Oreos and spread it carefully to cover. Don’t worry if some Oreos peek through – those orange centers make for a festive surprise! Finally, sprinkle your crushed Oreos over the top like edible confetti.
Bake for exactly 30 minutes – no peeking before then! The hardest part? Letting them cool completely before slicing (but I won’t judge if you sneak a warm corner piece…).

Tips for Perfect Halloween Oreo Stuffed Brownies
After making these brownies more times than I can count (what can I say? My kids are obsessed), I’ve picked up some game-changing tricks:
- Cold eggs are non-negotiable: Room temp eggs make greasy brownies – the cold ones emulsify better with the melted butter for that perfect fudgy texture.
- Parchment paper is your best friend: Line that pan with overhanging edges so you can lift the whole batch out cleanly – no more broken brownies!
- Patience pays off: I know it’s hard, but let them cool completely before slicing. They’ll hold their shape better and get even fudgier as they sit.
- Store smart: Layer them between parchment in an airtight container – they’ll stay fresh for 3 days (if they last that long!). For longer storage, freeze them – they thaw perfectly in about 30 minutes.
Follow these tips, and you’ll have the most Instagram-worthy, crowd-pleasing brownies on the block!
Halloween Oreo Stuffed Brownies Variations
Want to mix things up? This recipe is super flexible! Swap those Halloween Oreos for mint ones if you’re feeling festive (red and green creme looks amazing against the dark chocolate). For extra Halloween flair, add ½ teaspoon orange extract to the batter – it gives that “pumpkin spice” vibe without overpowering the chocolate. Peanut butter Oreos? Yes please! Just keep the total cookie count the same. The best part? No matter what combo you try, you’ll still get that magical Oreo surprise in every bite.
How to Store Halloween Oreo Stuffed Brownies
Here’s the deal – these brownies disappear fast in my house, but if you somehow have leftovers (miracle!), store them right. At room temp, keep them in an airtight container with parchment between layers for up to 3 days. Want to save some for later? Freeze them individually wrapped – they’ll stay perfect for a whole month! Just thaw at room temp for 30 minutes when the craving hits. Pro tip: The Oreos stay surprisingly crisp even after freezing!
Halloween Oreo Stuffed Brownies FAQs
Can I use regular Oreos?
Absolutely! Regular Oreos work perfectly fine in this recipe, but here’s the thing – those Halloween ones with the orange creme centers make these brownies extra special. They peek through the batter like little festive surprises that’ll make everyone smile. That said, any Oreo flavor you love will work – golden, mint, even the peanut butter ones. The recipe is all about that cookie crunch surprise!
Why cold eggs?
Oh, this is a good one! Cold eggs might seem counterintuitive, but trust me – they’re the secret to that perfect fudgy texture. Room temperature eggs can make the brownies turn out greasy because they don’t emulsify properly with the melted butter. Cold eggs help create that dense, rich structure we all love in brownies. Pro tip: I keep mine in the fridge until the very last second before adding them to the batter.
Can I double the recipe?
You bet! Doubling the recipe is actually how I make these for school bake sales. Just use a 9×13-inch pan instead of the 8×8-inch one, and add about 5-7 minutes to the baking time (start checking at 35 minutes). The layers will be slightly thinner, but you’ll still get that awesome Oreo surprise in every bite. Bonus? More brownies to share… or not! No judgment here if you want to keep them all to yourself.
Nutritional Information
Okay, let’s keep it real – these Halloween Oreo stuffed brownies aren’t exactly health food (but hey, it’s Halloween!). Here’s the nutritional scoop per brownie, based on cutting the pan into 9 generous squares:
